A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

The Attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service against the United States naval base at Pearl Harbor, Hawaii Territory, on Sunday morning, December 7, 1941. The attack, also known as the Battle of Pearl Harbor,led to the United States' formal entry into World War II. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning.
In the military of the United States, strikes and raids are a group of military operations that, alongside quite a number of others, come under the formal umbrella of military operations other than war (MOOTW). Ex-military authors Bonn and Baker describe them as "nothing more than the conduct of conventional combat missions on an individual or small-scale basis", and what they mean, specifically, depends on which particular branch of the military is using them. However, they do have formal, general, definitions in the United States Department of Defense's Joint Publication 1-02:
The Imperial Japanese Navy Air Service was the air arm of the Imperial Japanese Navy. The organization was responsible for the operation of naval aircraft and the conduct of aerial warfare in the Pacific War.
The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.
Japan intended the attack as a preventive action to keep the U.S. Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. Over the course of seven hours there were coordinated Japanese attacks on the U.S.-held Philippines, Guam and Wake Island and on the British Empire in Malaya, Singapore, and Hong Kong.Additionally, from the Japanese viewpoint, it was seen as a preemptive strike.
The Empire of Japan was the historical nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.
A preventive war is a war or military action initiated to prevent another party from acquiring a capability for attacking. The party being attacked has either a latent threat capability or has shown through its posturing that it intends to follow through with a future attack. Preventive war aims to forestall a shift in the balance of power by strategically attacking before the balance of power has had a chance to shift in the favour of the adversary. Preventive war is distinct from preemptive strike, which is first strike when an attack is imminent.
Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the countries that are geographically south of China and Japan, east of India, west of Papua New Guinea, and north of Australia. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia and the Indian Ocean. The region is the only part of Asia that lies partly within the Southern Hemisphere, although the majority of it is in the Northern Hemisphere. In contemporary definition, Southeast Asia consists of two geographic regions:
The attack commenced at 7:48 a.m. Hawaiian Time (18:18 GMT). The base was attacked by 353 Imperial Japanese aircraft (including fighters, level and dive bombers, and torpedo bombers) in two waves, launched from six aircraft carriers. All eight U.S. Navy battleships were damaged, with four sunk. All but USS Arizona were later raised, and six were returned to service and went on to fight in the war. The Japanese also sank or damaged three cruisers, three destroyers, an anti-aircraft training ship, and one minelayer. 188 U.S. aircraft were destroyed; 2,403 Americans were killed and 1,178 others were wounded. Important base installations such as the power station, dry dock, shipyard, maintenance, and fuel and torpedo storage facilities, as well as the submarine piers and headquarters building (also home of the intelligence section), were not attacked. Japanese losses were light: 29 aircraft and five midget submarines lost, and 64 servicemen killed. One Japanese sailor, Kazuo Sakamaki, was captured. Japan declared war on the United States on 8 December (9 December in Tokyo).
A fighter aircraft is a military aircraft designed primarily for air-to-air combat against other aircraft, as opposed to bombers and attack aircraft, whose main mission is to attack ground targets. The hallmarks of a fighter are its speed, maneuverability, and small size relative to other combat aircraft.
A bomber is a combat aircraft designed to attack ground and naval targets by dropping air-to-ground weaponry, firing torpedoes and bullets, or deploying air-launched cruise missiles.
A torpedo bomber is a military aircraft designed primarily to attack ships with aerial torpedoes. Torpedo bombers came into existence just before the First World War almost as soon as aircraft were built that were capable of carrying the weight of a torpedo, and remained an important aircraft type until they were rendered obsolete by anti-ship missiles. They were an important element in many famous Second World War battles, notably the British attack at Taranto and the Japanese attack on Pearl Harbor.
The surprise attack came as a profound shock to the American people and led directly to the American entry into World War II in both the Pacific and European theaters. The following day, December 8, the United States declared war on Japan,and three days later, on December 11, Germany and Italy each declared war on the U.S. The U.S. responded with a declaration of war against Germany and Italy. Domestic support for non-interventionism, which had been fading since the Fall of France in 1940, disappeared.
The Pacific War, sometimes called the Asia–Pacific War, was the theater of World War II that was fought in the Pacific and Asia. It was fought over a vast area that included the Pacific Ocean and islands, the South West Pacific, South-East Asia, and in China.
The European theatre of World War II, also known as the Second European War, was a huge area of heavy fighting across Europe, from Germany's invasion of Poland on 1 September 1939 until the end of the war with the Soviet Union conquering most of Eastern Europe along with the German unconditional surrender on 8 May 1945. The Allied powers fought the Axis powers on two major fronts as well as in a massive air war and in the adjoining Mediterranean and Middle East theatre.
On December 8, 1941, the United States Congress declared war on the Empire of Japan in response to that country's surprise attack on Pearl Harbor the prior day. It was formulated an hour after the Infamy Speech of US President Franklin D. Roosevelt. Japan had sent a message to the United States to its embassy in Washington earlier, but because of problems at the embassy in decoding the very long message – the high-security level assigned to the declaration meant that only personnel with very high clearances could decode it, which slowed down the process – it was not delivered to the U.S. Secretary of State until after the Pearl Harbor attack. Following the U.S. declaration, Japan's allies, Germany and Italy, declared war on the United States, bringing the United States fully into World War II.
There were numerous historical precedents for the unannounced military action by Japan, but the lack of any formal warning, particularly while peace negotiations were still apparently ongoing, led President Franklin D. Roosevelt to proclaim December 7, 1941, "a date which will live in infamy". Because the attack happened without a declaration of war and without explicit warning, the attack on Pearl Harbor was later judged in the Tokyo Trials to be a war crime.
Franklin Delano Roosevelt, often referred to by his initials FDR, was an American statesman and political leader who served as the 32nd president of the United States from 1933 until his death in 1945. A Democrat, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which realigned American politics into the Fifth Party System and defined American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II. Roosevelt is widely considered to be one of the most important figures in American history, as well as among the most influential figures of the 20th century. Though he has also been subject to much criticism, he is generally rated by scholars as one of the three greatest U.S. presidents, along with George Washington and Abraham Lincoln.
The Infamy Speech was a speech delivered by United States President Franklin D. Roosevelt to a Joint Session of the US Congress on December 8, 1941, one day after the Empire of Japan's attack on the US naval base at Pearl Harbor, Hawaii, and the Japanese declaration of war on the United States and the British Empire. The name derives from the first line of the speech: Roosevelt describing the previous day as "a date which will live in infamy". The speech is also commonly referred to as the "Pearl Harbor Speech".
The International Military Tribunal for the Far East (IMTFE), also known as the Tokyo Trial or the Tokyo War Crimes Tribunal, was a military trial convened on April 29, 1946, to try the leaders of the Empire of Japan for joint conspiracy to start and wage war, conventional war crimes and crimes against humanity.
War between Japan and the United States had been a possibility that each nation had been aware of, and planned for, since the 1920s. The relationship between the two countries was cordial enough that they remained trading partners.Tensions did not seriously grow until Japan's invasion of Manchuria in 1931. Over the next decade, Japan expanded into China, leading to the Second Sino-Japanese War in 1937. Japan spent considerable effort trying to isolate China, and endeavored to secure enough independent resources to attain victory on the mainland. The "Southern Operation" was designed to assist these efforts.
Starting in December 1937, events such as the Japanese attack on USS Panay, the Allison incident, and the Nanking Massacre swung Western public opinion sharply against Japan. Fearing Japanese expansion,the United States, United Kingdom, and France assisted China with its loans for war supply contracts.
In 1940, Japan invaded French Indochina, attempting to stymie the flow of supplies reaching China. The United States halted shipments of airplanes, parts, machine tools, and aviation gasoline to Japan, which the latter perceived as an unfriendly act.The United States did not stop oil exports, however, partly because of the prevailing sentiment in Washington: given Japanese dependence on American oil, such an action was likely to be considered an extreme provocation.
In mid-1940, President Franklin D. Roosevelt moved the Pacific Fleet from San Diego to Hawaii. [ self-published source ] By 1941, U.S. planners expected to abandon the Philippines at the outbreak of war. Late that year, Admiral Thomas C. Hart, commander of the Asiatic Fleet, was given orders to that effect.He also ordered a military buildup in the Philippines, taking both actions in the hope of discouraging Japanese aggression in the Far East. Because the Japanese high command was (mistakenly) certain any attack on the United Kingdom's Southeast Asian colonies, including Singapore, would bring the U.S. into the war, a devastating preventive strike appeared to be the only way to prevent American naval interference. An invasion of the Philippines was also considered necessary by Japanese war planners. The U.S. War Plan Orange had envisioned defending the Philippines with an elite force of 40,000 men; this option was never implemented due to opposition from Douglas MacArthur, who felt he would need a force ten times that size.
The U.S. finally ceased oil exports to Japan in July 1941, following the seizure of French Indochina after the Fall of France, in part because of new American restrictions on domestic oil consumption.Because of this decision, Japan proceeded with plans to take the oil-rich Dutch East Indies. On August 17, Roosevelt warned Japan that America was prepared to take opposing steps if "neighboring countries" were attacked. The Japanese were faced with a dichotomy—either withdraw from China and lose face, or seize new sources of raw materials in the resource-rich European colonies of Southeast Asia.
Japan and the U.S. engaged in negotiations during 1941, attempting to improve relations. In the course of these negotiations, Japan offered to withdraw from most of China and Indochina after making peace with the Nationalist government. It also proposed to adopt an independent interpretation of the Tripartite Pact and to refrain from trade discrimination, provided all other nations reciprocated. Washington rejected these proposals. Japanese Prime Minister Konoye then offered to meet with Roosevelt, but Roosevelt insisted on reaching an agreement before any meeting.The U.S. ambassador to Japan repeatedly urged Roosevelt to accept the meeting, warning that it was the only way to preserve the conciliatory Konoye government and peace in the Pacific. However, his recommendation was not acted upon. The Konoye government collapsed the following month, when the Japanese military rejected a withdrawal of all troops from China.
Japan's final proposal, delivered on November 20, offered to withdraw from southern Indochina and to refrain from attacks in Southeast Asia, so long as the United States, United Kingdom, and Netherlands ceased aid to China and lifted their sanctions against Japan.The American counter-proposal of November 26 (November 27 in Japan), the Hull note, required Japan completely evacuate China without conditions and conclude non-aggression pacts with Pacific powers. On November 26 in Japan, the day before the note's delivery, the Japanese task force left port for Pearl Harbor.
The Japan intended the attack as a preventive action to keep the U.S. Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. Over the course of seven hours there were coordinated Japanese attacks on the U.S.-held Philippines, Guam and Wake Island and on the British Empire in Malaya, Singapore, and Hong Kong.Additionally, from the Japanese viewpoint, it was seen as a preemptive strike 'before the oil gauge ran empty'.
Preliminary planning for an attack on Pearl Harbor to protect the move into the "Southern Resource Area" (the Japanese term for the Dutch East Indies and Southeast Asia generally) had begun very early in 1941 under the auspices of Admiral Isoroku Yamamoto, then commanding Japan's Combined Fleet.He won assent to formal planning and training for an attack from the Imperial Japanese Navy General Staff only after much contention with Naval Headquarters, including a threat to resign his command. Full-scale planning was underway by early spring 1941, primarily by Rear Admiral Ryūnosuke Kusaka, with assistance from Captain Minoru Genda and Yamamoto's Deputy Chief of Staff, Captain Kameto Kuroshima. The planners studied the 1940 British air attack on the Italian fleet at Taranto intensively.
Over the next several months, pilots were trained, equipment was adapted, and intelligence was collected. Despite these preparations, Emperor Hirohito did not approve the attack plan until November 5, after the third of four Imperial Conferences called to consider the matter.Final authorization was not given by the emperor until December 1, after a majority of Japanese leaders advised him the "Hull Note" would "destroy the fruits of the China incident, endanger Manchukuo and undermine Japanese control of Korea."
By late 1941, many observers believed that hostilities between the U.S. and Japan were imminent. A Gallup poll just before the attack on Pearl Harbor found that 52% of Americans expected war with Japan, 27% did not, and 21% had no opinion.While U.S. Pacific bases and facilities had been placed on alert on many occasions, U.S. officials doubted Pearl Harbor would be the first target; instead, they expected the Philippines would be attacked first. This presumption was due to the threat that the air bases throughout the country and the naval base at Manila posed to sea lanes, as well as to the shipment of supplies to Japan from territory to the south. They also incorrectly believed that Japan was not capable of mounting more than one major naval operation at a time.
The Japanese attack had several major aims. First, it intended to destroy important American fleet units, thereby preventing the Pacific Fleet from interfering with Japanese conquest of the Dutch East Indies and Malaya and to enable Japan to conquer Southeast Asia without interference. Second, it was hoped to buy time for Japan to consolidate its position and increase its naval strength before shipbuilding authorized by the 1940 Vinson-Walsh Act erased any chance of victory.Third, to deliver a blow to America's ability to mobilize its forces in the Pacific, battleships were chosen as the main targets, since they were the prestige ships of any navy at the time. Finally, it was hoped that the attack would undermine American morale such that the U.S. government would drop its demands contrary to Japanese interests, and would seek a compromise peace with Japan.
Striking the Pacific Fleet at anchor in Pearl Harbor carried two distinct disadvantages: the targeted ships would be in very shallow water, so it would be relatively easy to salvage and possibly repair them; and most of the crews would survive the attack, since many would be on shore leave or would be rescued from the harbor. A further important disadvantage—this of timing, and known to the Japanese—was the absence from Pearl Harbor of all three of the U.S. Pacific Fleet's aircraft carriers (Enterprise, Lexington, and Saratoga). IJN top command was attached to Admiral Mahan's "decisive battle" doctrine, especially that of destroying the maximum number of battleships. Despite these concerns, Yamamoto decided to press ahead. [ page needed ]
Japanese confidence in their ability to achieve a short, victorious war also meant other targets in the harbor, especially the navy yard, oil tank farms, and submarine base, were ignored, since—by their thinking—the war would be over before the influence of these facilities would be felt.
On November 26, 1941, a Japanese task force (the Striking Force) of six aircraft carriers—Akagi, Kaga, Sōryū, Hiryū, Shōkaku, and Zuikaku—departed Hittokapu Bay on Kasatka (now Iterup) Island in the Kurile Islands, en route to a position northwest of Hawaii, intending to launch its 408 aircraft to attack Pearl Harbor: 360 for the two attack waves and 48 on defensive combat air patrol (CAP), including nine fighters from the first wave.
The first wave was to be the primary attack, while the second wave was to attack carriers as its first objective and cruisers as its second, with battleships as the third target. [ citation needed ]The first wave carried most of the weapons to attack capital ships, mainly specially adapted Type 91 aerial torpedoes which were designed with an anti-roll mechanism and a rudder extension that let them operate in shallow water. The aircrews were ordered to select the highest value targets (battleships and aircraft carriers) or, if these were not present, any other high value ships (cruisers and destroyers). First wave dive bombers were to attack ground targets. Fighters were ordered to strafe and destroy as many parked aircraft as possible to ensure they did not get into the air to intercept the bombers, especially in the first wave. When the fighters' fuel got low they were to refuel at the aircraft carriers and return to combat. Fighters were to serve CAP duties where needed, especially over U.S. airfields.
Before the attack commenced, the Imperial Japanese Navy launched reconnaissance floatplanes from cruisers Chikuma and Tone, one to scout over Oahu and the other over Lahaina Roads, Maui, respectively, with orders to report on U.S. fleet composition and location.Reconnaissance aircraft flights risked alerting the U.S., and were not necessary. U.S. fleet composition and preparedness information in Pearl Harbor were already known due to the reports of the Japanese spy Takeo Yoshikawa. A report of the absence of the U.S. fleet in Lahaina anchorage off Maui was received from the Tone's floatplane and fleet submarine I-72. Another four scout planes patrolled the area between the Japanese carrier force (the Kidō Butai) and Niihau, to detect any counterattack.
Fleet submarines I-16, I-18, I-20, I-22, and I-24 each embarked a Type A midget submarine for transport to the waters off Oahu. 10 nmi (19 km; 12 mi) of the mouth of Pearl Harbor and launched their midget subs at about 01:00 local time on December 7. At 03:42 Hawaiian Time, the minesweeper Condor spotted a midget submarine periscope southwest of the Pearl Harbor entrance buoy and alerted the destroyer Ward. The midget may have entered Pearl Harbor. However, Ward sank another midget submarine at 06:37 in the first American shots in the Pacific Theater. A midget submarine on the north side of Ford Island missed the seaplane tender Curtiss with her first torpedo and missed the attacking destroyer Monaghan with her other one before being sunk by Monaghan at 08:43.The five I-boats left Kure Naval District on November 25, 1941. On December 6, they came to within
A third midget submarine, Ha-19 , grounded twice, once outside the harbor entrance and again on the east side of Oahu, where it was captured on December 8.Ensign Kazuo Sakamaki swam ashore and was captured by Hawaii National Guard Corporal David Akui, becoming the first Japanese prisoner of war. A fourth had been damaged by a depth charge attack and was abandoned by its crew before it could fire its torpedoes. Japanese forces received a radio message from a midget submarine at 00:41 on December 8 claiming damage to one or more large warships inside Pearl Harbor.
In 1992, 2000, and 2001, Hawaii Undersea Research Laboratory's submersibles found the wreck of the fifth midget submarine lying in three parts outside Pearl Harbor. The wreck was in the debris field where much surplus U.S. equipment was dumped after the war, including vehicles and landing craft. Both of its torpedoes were missing. This correlates with reports of two torpedoes fired at the light cruiser St. Louis at 10:04 at the entrance of Pearl Harbor, and a possible torpedo fired at destroyer Helm at 08:21.
The attack took place before any formal declaration of war was made by Japan, but this was not Admiral Yamamoto's intention. He originally stipulated that the attack should not commence until thirty minutes after Japan had informed the United States that peace negotiations were at an end.However, the attack began before the notice could be delivered. Tokyo transmitted the 5000-word notification (commonly called the "14-Part Message") in two blocks to the Japanese Embassy in Washington. Transcribing the message took too long for the Japanese ambassador to deliver it on schedule; in the event, it was not presented until more than an hour after the attack began. (In fact, U.S. code breakers had already deciphered and translated most of the message hours before he was scheduled to deliver it.) The final part is sometimes described as a declaration of war. While it was viewed by a number of senior U.S government and military officials as a very strong indicator negotiations were likely to be terminated and that war might break out at any moment, it neither declared war nor severed diplomatic relations. A declaration of war was printed on the front page of Japan's newspapers in the evening edition of December 8, but not delivered to the U.S. government until the day after the attack.
For decades, conventional wisdom held that Japan attacked without first formally breaking diplomatic relations only because of accidents and bumbling that delayed the delivery of a document hinting at war to Washington. In 1999, however, Takeo Iguchi, a professor of law and international relations at International Christian University in Tokyo, discovered documents that pointed to a vigorous debate inside the government over how, and indeed whether, to notify Washington of Japan's intention to break off negotiations and start a war, including a December 7 entry in the war diary saying, "[O]ur deceptive diplomacy is steadily proceeding toward success." Of this, Iguchi said, "The diary shows that the army and navy did not want to give any proper declaration of war, or indeed prior notice even of the termination of negotiations ... and they clearly prevailed."
In any event, even if the Japanese had decoded and delivered the 14-Part Message before the beginning of the attack, it would not have constituted either a formal break of diplomatic relations or a declaration of war. The final two paragraphs of the message read:
Thus the earnest hope of the Japanese Government to adjust Japanese-American relations and to preserve and promote the peace of the Pacific through cooperation with the American Government has finally been lost.
The Japanese Government regrets to have to notify hereby the American Government that in view of the attitude of the American Government it cannot but consider that it is impossible to reach an agreement through further negotiations.
The first attack wave of 183 planes was launched north of Oahu, led by Commander Mitsuo Fuchida.Six planes failed to launch due to technical difficulties. It included:
As the first wave approached Oahu, it was detected by the U.S. Army SCR-270 radar at Opana Point near the island's northern tip. This post had been in training mode for months, but was not yet operational.The operators, Privates George Elliot Jr. and Joseph Lockard, reported a target. But Lieutenant Kermit A. Tyler, a newly assigned officer at the thinly manned Intercept Center, presumed it was the scheduled arrival of six B-17 bombers from California. The Japanese planes were approaching from a direction very close (only a few degrees difference) to the bombers, and while the operators had never seen a formation as large on radar, they neglected to tell Tyler of its size. Tyler, for security reasons, could not tell the operators of the six B-17s that were due (even though it was widely known).
As the first wave planes approached Oahu, they encountered and shot down several U.S. aircraft. At least one of these radioed a somewhat incoherent warning. Other warnings from ships off the harbor entrance were still being processed or awaiting confirmation when the attacking planes began bombing and strafing. Nevertheless, it is not clear any warnings would have had much effect even if they had been interpreted correctly and much more promptly. The results the Japanese achieved in the Philippines were essentially the same as at Pearl Harbor, though MacArthur had almost nine hours warning that the Japanese had already attacked Pearl Harbor.
The air portion of the attack began at 7:48 a.m. Hawaiian Time (3:18 a.m. December 8 Japanese Standard Time, as kept by ships of the Kido Butai), with the attack on Kaneohe. A total of 353 Japanese planes in two waves reached Oahu. Slow, vulnerable torpedo bombers led the first wave, exploiting the first moments of surprise to attack the most important ships present (the battleships), while dive bombers attacked U.S. air bases across Oahu, starting with Hickam Field, the largest, and Wheeler Field, the main U.S. Army Air Forces fighter base. The 171 planes in the second wave attacked the Army Air Forces' Bellows Field near Kaneohe on the windward side of the island, and Ford Island. The only aerial opposition came from a handful of P-36 Hawks, P-40 Warhawks, and some SBD Dauntless dive bombers from the carrier Enterprise.
In the first wave attack, about eight of the forty-nine 800 kg (1760 lb) armor-piercing bombs dropped hit their intended battleship targets. At least two of those bombs broke up on impact, another detonated before penetrating an unarmored deck, and one was a dud. Thirteen of the forty torpedoes hit battleships, and four torpedoes hit other ships. Men aboard U.S. ships awoke to the sounds of alarms, bombs exploding, and gunfire, prompting bleary-eyed men to dress as they ran to General Quarters stations. (The famous message, "Air raid Pearl Harbor. This is not drill.", was sent from the headquarters of Patrol Wing Two, the first senior Hawaiian command to respond.) The defenders were very unprepared. Ammunition lockers were locked, aircraft parked wingtip to wingtip in the open to prevent sabotage, guns unmanned (none of the Navy's 5"/38s, only a quarter of its machine guns, and only four of 31 Army batteries got in action). Despite this low alert status, many American military personnel responded effectively during the attack. Ensign Joe Taussig Jr., aboard Nevada, commanded the ship's antiaircraft guns and was severely wounded, but continued to be on post. Lt. Commander F. J. Thomas commanded Nevada in the captain's absence and got her under way until the ship was grounded at 9:10 a.m. One of the destroyers, Aylwin, got underway with only four officers aboard, all ensigns, none with more than a year's sea duty; she operated at sea for 36 hours before her commanding officer managed to get back aboard. Captain Mervyn Bennion, commanding West Virginia, led his men until he was cut down by fragments from a bomb which hit Tennessee, moored alongside.
The second planned wave consisted of 171 planes: 54 B5Ns, 81 D3As, and 36 A6Ms, commanded by Lieutenant-Commander Shigekazu Shimazaki.Four planes failed to launch because of technical difficulties. This wave and its targets comprised:
The second wave was divided into three groups. One was tasked to attack Kāneʻohe, the rest Pearl Harbor proper. The separate sections arrived at the attack point almost simultaneously from several directions.
Ninety minutes after it began, the attack was over. 2,008 sailors were killed, and 710 others wounded; 218 soldiers and airmen (who were part of the Army prior to the independent United States Air Force in 1947) were killed and 364 wounded; 109 marines were killed and 69 wounded; and 68 civilians were killed and 35 wounded. In total, 2,403 Americans were killed and 1,143 were wounded.Eighteen ships were sunk or run aground, including five battleships. All of the Americans killed or wounded during the attack were non-combatants, given the fact there was no state of war when the attack occurred.
Of the American fatalities, nearly half were due to the explosion of Arizona's forward magazine after it was hit by a modified 16-inch (410 mm) shell.
Already damaged by a torpedo and on fire amidships, Nevada attempted to exit the harbor. She was targeted by many Japanese bombers as she got under way and sustained more hits from 250 lb (113 kg) bombs, which started further fires. She was deliberately beached to avoid blocking the harbor entrance.
California was hit by two bombs and two torpedoes. The crew might have kept her afloat, but were ordered to abandon ship just as they were raising power for the pumps. Burning oil from Arizona and West Virginia drifted down on her, and probably made the situation look worse than it was. The disarmed target ship Utah was holed twice by torpedoes. West Virginia was hit by seven torpedoes, the seventh tearing away her rudder. Oklahoma was hit by four torpedoes, the last two above her belt armor, which caused her to capsize. Maryland was hit by two of the converted 16" shells, but neither caused serious damage.
Although the Japanese concentrated on battleships (the largest vessels present), they did not ignore other targets. The light cruiser Helena was torpedoed, and the concussion from the blast capsized the neighboring minelayer Oglala. Two destroyers in dry dock, Cassin and Downes were destroyed when bombs penetrated their fuel bunkers. The leaking fuel caught fire; flooding the dry dock in an effort to fight fire made the burning oil rise, and both were burned out. Cassin slipped from her keel blocks and rolled against Downes. The light cruiser Raleigh was holed by a torpedo. The light cruiser Honolulu was damaged, but remained in service. The repair vessel Vestal, moored alongside Arizona, was heavily damaged and beached. The seaplane tender Curtiss was also damaged. The destroyer Shaw was badly damaged when two bombs penetrated her forward magazine.
Of the 402 American aircraft in Hawaii, 188 were destroyed and 159 damaged, 155 of them on the ground.Almost none were actually ready to take off to defend the base. Eight Army Air Forces pilots managed to get airborne during the attack and six were credited with downing at least one Japanese aircraft during the attack: 1st Lt. Lewis M. Sanders, 2nd Lt. Philip M. Rasmussen, 2nd Lt. Kenneth M. Taylor, 2nd Lt. George S. Welch, 2nd Lt. Harry W. Brown, and 2nd Lt. Gordon H. Sterling Jr. Sterling was shot down by Lt. Fujita over Kaneohe Bay and is listed as Body Not Recovered (not Missing In Action). Lt. John L. Dains was killed by friendly fire returning from a victory over Kaawa. Of 33 PBYs in Hawaii, 24 were destroyed, and six others damaged beyond repair. (The three on patrol returned undamaged.) Friendly fire brought down some U.S. planes on top of that, including five from an inbound flight from Enterprise. Japanese attacks on barracks killed additional personnel.
At the time of the attack, nine civilian aircraft were flying in the vicinity of Pearl Harbor. Of these, three were shot down.
Fifty-five Japanese airmen and nine submariners were killed in the attack, and one was captured. Of Japan's 414available planes, 29 were lost during the battle (nine in the first attack wave, 20 in the second), with another 74 damaged by antiaircraft fire from the ground.
Several Japanese junior officers including Fuchida and Genda urged Nagumo to carry out a third strike in order to destroy as much of Pearl Harbor's fuel and torpedostorage, maintenance, and dry dock facilities as possible. Genda, who had unsuccessfully advocated for invading Hawaii after the air attack, believed that without an invasion, three strikes were necessary to disable the base as much as possible. The captains of the other five carriers in the task force reported they were willing and ready to carry out a third strike. Military historians have suggested the destruction of these shore facilities would have hampered the U.S. Pacific Fleet far more seriously than the loss of its battleships. If they had been wiped out, "serious [American] operations in the Pacific would have been postponed for more than a year"; according to Admiral Chester W. Nimitz, later Commander in Chief of the Pacific Fleet, "it would have prolonged the war another two years." Nagumo, however, decided to withdraw for several reasons:
At a conference aboard his flagship the following morning, Yamamoto supported Nagumo's withdrawal without launching a third wave.In retrospect, sparing the vital dockyards, maintenance shops, and the oil tank farm meant the U.S. could respond relatively quickly to Japanese activities in the Pacific. Yamamoto later regretted Nagumo's decision to withdraw and categorically stated it had been a great mistake not to order a third strike.
Twenty-one ships were damaged or lost in the attack, of which all but three were repaired and returned to service.
After a systematic search for survivors, formal salvage operations began. Captain Homer N. Wallin, Material Officer for Commander, Battle Force, U.S. Pacific Fleet, was immediately ordered to lead salvage operations. "Within a short time I was relieved of all other duties and ordered to full time work as Fleet Salvage Officer."
Around Pearl Harbor, divers from the Navy (shore and tenders), the Pearl Harbor Naval Shipyard, and civilian contractors (Pacific Bridge and others) began work on the ships that could be refloated. They patched holes, cleared debris, and pumped water out of ships. Navy divers worked inside the damaged ships. Within six months, five battleships and two cruisers were patched or refloated so they could be sent to shipyards in Pearl Harbor and on the mainland for extensive repair.
Intensive salvage operations continued for another year, a total of some 20,000 man-hours under water.Oklahoma, while successfully raised, was never repaired, and capsized while under tow to the mainland in 1947. Arizona and the target ship Utah were too heavily damaged for salvage, though much of their armament and equipment was removed and put to use aboard other vessels. Today, the two hulks remain where they were sunk, with Arizona becoming a war memorial.
In the wake of the attack, 15 Medals of Honor, 51 Navy Crosses, 53 Silver Stars, four Navy and Marine Corps Medals, one Distinguished Flying Cross, four Distinguished Service Crosses, one Distinguished Service Medal, and three Bronze Star Medals were awarded to the American servicemen who distinguished themselves in combat at Pearl Harbor.Additionally, a special military award, the Pearl Harbor Commemorative Medal, was later authorized for all military veterans of the attack.
The attack outraged American public opinion, turning a once isolationist country into committing an all-out war to the death against the Japanese Empire. The day after the attack, Roosevelt delivered his famous Infamy Speech to a Joint Session of Congress, calling for a formal declaration of war on the Empire of Japan. Congress obliged his request less than an hour later. On December 11, Germany and Italy declared war on the United States, even though the Tripartite Pact did not require it.Congress issued a declaration of war against Germany and Italy later that same day. The UK actually declared war on Japan nine hours before the U.S. did, partially due to Japanese attacks on Malaya, Singapore and Hong Kong, and partially due to Winston Churchill's promise to declare war "within the hour" of a Japanese attack on the United States.
The attack was an initial shock to all the Allies in the Pacific Theater. Further losses compounded the alarming setback. Japan attacked the Philippines hours later (because of the time difference, it was December 8 in the Philippines). Only three days after the attack on Pearl Harbor, the battleships Prince of Wales and Repulse were sunk off the coast of Malaya, causing British Prime Minister Winston Churchill later to recollect "In all the war I never received a more direct shock. As I turned and twisted in bed the full horror of the news sank in upon me. There were no British or American capital ships in the Indian Ocean or the Pacific except the American survivors of Pearl Harbor who were hastening back to California. Over this vast expanse of waters Japan was supreme and we everywhere were weak and naked".
Throughout the war, Pearl Harbor was frequently used in American propaganda.
One further consequence of the attack on Pearl Harbor and its aftermath (notably the Niihau incident) was that Japanese American residents and citizens were relocated to nearby Japanese-American internment camps. Within hours of the attack, hundreds of Japanese American leaders were rounded up and brought to high-security camps such as Sand Island at the mouth of Honolulu harbor and Kilauea Military Camp on the island of Hawaii.Eventually, more than 110,000 Japanese Americans, nearly all who lived on the West Coast, were forced into interior camps, but in Hawaii, where the 150,000-plus Japanese Americans composed over one-third of the population, only 1,200 to 1,800 were interned.
The attack also had international consequences. The Canadian province of British Columbia, bordering the Pacific Ocean, had long had a large population of Japanese immigrants and their Japanese Canadian descendants. Pre-war tensions were exacerbated by the Pearl Harbor attack, leading to a reaction from the Government of Canada. On February 24, 1942, Order-in-Council P.C. no. 1486 was passed under the War Measures Act allowing for the forced removal of any and all Canadians of Japanese descent from British Columbia, as well as the prohibiting them from returning to the province. On 4 March, regulations under the Act were adopted to evacuate Japanese-Canadians.As a result, 12,000 were interned in interior camps, 2,000 were sent to road camps and another 2,000 were forced to work in the prairies at sugar beet farms.
The Japanese planners had determined that some means was required for rescuing fliers whose aircraft were too badly damaged to return to the carriers. The island of Niihau, only 30 minutes flying time from Pearl Harbor, was designated as the rescue point.
The Zero flown by Petty Officer Shigenori Nishikaichi of Hiryu was damaged in the attack on Wheeler, so he flew to the rescue point on Niihau. The aircraft was further damaged on landing. Nishikaichi was helped from the wreckage by one of the native Hawaiians, who, aware of the tension between the United States and Japan, took the pilot's maps and other documents. The island's residents had no telephones or radio and were completely unaware of the attack on Pearl Harbor. Nishikaichi enlisted the support of three Japanese-American residents in an attempt to recover the documents. During the ensuing struggles, Nishikaichi was killed and a Hawaiian civilian was wounded; one collaborator committed suicide, and his wife and the third collaborator were sent to prison.
The ease with which the local ethnic Japanese residents had apparently gone to the assistance of Nishikaichi was a source of concern for many, and tended to support those who believed that local Japanese could not be trusted.
Admiral Hara Tadaichi summed up the Japanese result by saying, "We won a great tactical victory at Pearl Harbor and thereby lost the war."To a similar effect, see Isoroku Yamamoto's alleged "sleeping giant" quote.
While the attack accomplished its intended objective, it turned out to be largely unnecessary. Unbeknownst to Yamamoto, who conceived the original plan, the U.S. Navy had decided as far back as 1935 to abandon 'charging' across the Pacific towards the Philippines in response to an outbreak of war (in keeping with the evolution of Plan Orange).The U.S. instead adopted "Plan Dog" in 1940, which emphasized keeping the IJN out of the eastern Pacific and away from the shipping lanes to Australia, while the U.S. concentrated on defeating Nazi Germany.
Fortunately for the United States, the American aircraft carriers were untouched by the Japanese attack; otherwise the Pacific Fleet's ability to conduct offensive operations would have been crippled for a year or more (given no diversions from the Atlantic Fleet). As it was, the elimination of the battleships left the U.S. Navy with no choice but to rely on its aircraft carriers and submarines—the very weapons with which the U.S. Navy halted and eventually reversed the Japanese advance. While six of the eight battleships were repaired and returned to service, their relatively low speed and high fuel consumption limited their deployment, and they served mainly in shore bombardment roles (their only major action being the Battle of Surigao Strait in October 1944). A major flaw of Japanese strategic thinking was a belief that the ultimate Pacific battle would be fought by battleships, in keeping with the doctrine of Captain Alfred Thayer Mahan. As a result, Yamamoto (and his successors) hoarded battleships for a "decisive battle" that never happened.
The Japanese confidence in their ability to win a quick victory meant that they neglected Pearl Harbor's navy repair yards, oil tank farms, submarine base, and old headquarters building.All of these targets were omitted from Genda's list, yet they proved more important than any battleship to the American war efforts in the Pacific. The survival of the repair shops and fuel depots allowed Pearl Harbor to maintain logistical support to the U.S. Navy's operations, such as the Doolittle Raid and the Battles of Coral Sea and Midway. It was submarines that immobilized the Imperial Japanese Navy's heavy ships and brought Japan's economy to a virtual standstill by crippling the transportation of oil and raw materials: by the end of 1942, import of raw materials was cut to half of what it had been, "to a disastrous ten million tons", while oil import "was almost completely stopped". Lastly, the basement of the Old Administration Building was the home of the cryptanalytic unit which contributed significantly to the Midway ambush and the Submarine Force's success.
Ever since the Japanese attack, there has been debate as to how and why the United States had been caught unaware, and how much and when American officials knew of Japanese plans and related topics. Military officers including Gen. Billy Mitchell had pointed out the vulnerability of Pearl to air attack. At least two naval war games, one in 1932 and another in 1936, proved that Pearl was vulnerable to such an attack. Admiral James Richardson was removed from command shortly after protesting President Roosevelt's decision to move the bulk of the Pacific fleet to Pearl Harbor.The decisions of military and political leadership to ignore these warnings have contributed to conspiracy theories. Several writers, including journalist Robert Stinnett and former United States Rear Admiral Robert Alfred Theobald, have argued that various parties high in the U.S. and British governments knew of the attack in advance and may even have let it happen or encouraged it in order to force the U.S. into war via the so-called "back door". However, this conspiracy theory is rejected by mainstream historians.
Isoroku Yamamoto was a Japanese Marshal Admiral of the Navy and the commander-in-chief of the Combined Fleet during World War II until his death.
The Battle of Midway was a decisive naval battle in the Pacific Theater of World War II that took place between 4 and 7 June 1942, only six months after Japan's attack on Pearl Harbor and one month after the Battle of the Coral Sea. The United States Navy under Admirals Chester Nimitz, Frank Jack Fletcher, and Raymond A. Spruance defeated an attacking fleet of the Imperial Japanese Navy under Admirals Isoroku Yamamoto, Chūichi Nagumo, and Nobutake Kondō near Midway Atoll, inflicting devastating damage on the Japanese fleet that proved irreparable. Military historian John Keegan called it "the most stunning and decisive blow in the history of naval warfare".
Zuikaku was a Shōkaku-class aircraft carrier of the Imperial Japanese Navy. Her complement of aircraft took part in the attack on Pearl Harbor that formally brought the United States into the Pacific War, and she fought in several of the most important naval battles of the war, before being sunk during the Battle of Leyte Gulf.
USS Arizona was a Pennsylvania-class battleship built for and by the United States Navy in the mid-1910s. Named in honor of the 48th state's recent admission into the union, the ship was the second and last of the Pennsylvania class of "super-dreadnought" battleships. Although commissioned in 1916, the ship remained stateside during World War I. Shortly after the end of the war, Arizona was one of a number of American ships that briefly escorted President Woodrow Wilson to the Paris Peace Conference. The ship was sent to Turkey in 1919 at the beginning of the Greco-Turkish War to represent American interests for several months. Several years later, she was transferred to the Pacific Fleet and remained there for the rest of her career.
USS Nevada (BB-36), the second United States Navy ship to be named after the 36th state, was the lead ship of the two Nevada-class battleships. Launched in 1914, Nevada was a leap forward in dreadnought technology; four of her new features would be included on almost every subsequent US battleship: triple gun turrets, oil in place of coal for fuel, geared steam turbines for greater range, and the "all or nothing" armor principle. These features made Nevada, alongside its sister ship Oklahoma, the first US Navy "standard-type" battleships.
USS Enterprise (CV-6) was the seventh U.S. Navy vessel to bear the name. Colloquially called "The Big E", she was the sixth aircraft carrier of the United States Navy. A Yorktown-class carrier, she was launched in 1936 and was one of only three American carriers commissioned before World War II to survive the war. She participated in more major actions of the war against Japan than any other United States ship. These actions included the Attack on Pearl Harbor, the Battle of Midway, the Battle of the Eastern Solomons, the Battle of the Santa Cruz Islands, various other air-sea engagements during the Guadalcanal Campaign, the Battle of the Philippine Sea, and the Battle of Leyte Gulf. Enterprise earned 20 battle stars, the most for any U.S. warship in World War II, and was the most decorated U.S. ship of World War II. She is also the first American ship to sink an enemy warship during the Pacific War when she sank Japanese submarine I-70 on 10 December 1941. On three occasions during the Pacific War, the Japanese announced that she had been sunk in battle, inspiring her nickname "The Grey Ghost".
Mitsuo Fuchida was a Japanese captain in the Imperial Japanese Navy Air Service and a bomber aviator in the Japanese navy before and during World War II. He is perhaps best known for leading the first wave of air attacks on Pearl Harbor on 7 December 1941. Working under the overall fleet commander, Vice Admiral Chūichi Nagumo, Fuchida was responsible for the coordination of the entire aerial attack.
Battleship Row was the grouping of eight U.S. battleships in port at Pearl Harbor, Hawaii, when the Japanese attacked on 7 December 1941. These ships bore the brunt of the Japanese assault. They were moored next to Ford Island when the attack commenced. The ships were Arizona, California, Maryland, Nevada, Oklahoma, Pennsylvania, Tennessee, and West Virginia. A repair ship, Vestal, was also present, moored next to Arizona.
Isaac Campbell Kidd was an American Rear Admiral in the United States Navy. Kidd was killed on the bridge of USS Arizona during the Japanese attack on Pearl Harbor. He was the father of Admiral Isaac C. Kidd, Jr. He was a posthumous recipient of his nation's highest military honor—the Medal of Honor. The highest ranking casualty at Pearl Harbor, he became the first U.S. Navy flag officer killed in action in World War II as well as the first killed in action against any foreign enemy. A Fletcher-class destroyer, Kidd (DD-661), was commissioned in his honor on April 23, 1943. The second ship named after him, Kidd (DDG-993), lead ship of four Kidd-class destroyers, was commissioned on March 27, 1981. An Arleigh Burke-class guided missile destroyer, Kidd (DDG-100), was the third ship named after him and was commissioned on June 9, 2007.
Minoru Genda was a well-known Japanese military aviator and politician. He is best known for helping to plan the Pearl Harbor attack. He was also the third Chief of Staff of the Japan Air Self-Defense Force.
The 1st Air Fleet also known as the Kidō Butai, was a name used for a combined carrier battle group comprising most of the aircraft carriers and carrier air groups of the Imperial Japanese Navy (IJN), during the first eight months of the Pacific War.
The Pacific War is a series of alternate history novels written by Newt Gingrich and William R. Forstchen with Albert S. Hanser. The series deals with the Pacific War between the United States of America and the Empire of Japan. The point of divergence is the decision of Admiral Isoroku Yamamoto, commander-in-chief of the Japanese Combined Fleet, to take personal command of the 1st Air Fleet for the attack on Pearl Harbor, rather than delegate it to Adm. Chūichi Nagumo.
A series of events led to the attack on Pearl Harbor. War between Japan and the United States had been a possibility that each nation's military forces planned for in the 1920s, though real tension did not begin until the 1931 invasion of Manchuria by Japan. Over the next decade, Japan expanded slowly into China, leading to the Second Sino-Japanese war in 1937. In 1940 Japan invaded French Indochina in an effort to embargo all imports into China, including war supplies purchased from the U.S. This move prompted the United States to embargo all oil exports, leading the Imperial Japanese Navy (IJN) to estimate it had less than two years of bunker oil remaining and to support the existing plans to seize oil resources in the Dutch East Indies. Planning had been underway for some time on an attack on the "Southern Resource Area" to add it to the Greater East Asia Co-Prosperity Sphere Japan envisioned in the Pacific.
World War II saw the end of the battleship as the dominant force in the world's navies. On the outbreak of the War, large fleets of battleships—many inherited from the dreadnought era decades before—were one of the decisive forces in naval thinking. By the end of the War, battleship construction was all but halted, and almost every remaining battleship was retired or scrapped within a few years of its end.
The attacks on Kure and the Inland Sea by United States and British naval aircraft in late July 1945 led to the sinking of most of the surviving large warships of the Imperial Japanese Navy (IJN). The United States Third Fleet's attacks on Kure Naval Arsenal and nearby ports on 24, 25, and 28 July sank an aircraft carrier, three battleships, five cruisers, and several smaller warships. During the same period the British Pacific Fleet attacked other targets in the Inland Sea region and sank two escort ships and several smaller vessels as well as damaging an escort carrier. Many historians consider the Kure bombing as the Japanese Navy's Pearl Harbor.
Naval Station Pearl Harbor is a U.S. naval base adjacent to Honolulu, in the U.S. state of Hawaii. In 2010, along with the United States Air Force's Hickam Air Force Base, the facility was merged to form Joint Base Pearl Harbor–Hickam.
The attack on Yokosuka was an air raid conducted by the United States Navy on 18 July 1945 during the last weeks of the Pacific War. The Japanese battleship Nagato was the raid's main target, though anti-aircraft positions and other warships at Yokosuka Naval Arsenal were also attacked. Other U.S. Navy and British Royal Navy aircraft struck airfields in the Tokyo area.
The United States Navy grew rapidly during World War II from 1941–45, and played the central role in the war against Japan. It assisted the British Royal Navy in the naval war against Germany and Italy. The largest amphibious invasion of all time was the invasion of France in June 1944. The combatant warships were 79 percent British or Canadian, 17 percent American, and the remainder from other Allies.
Ford Island is an islet in the center of Pearl Harbor, Oahu, in the U.S. state of Hawaii. It has been known as Rabbit Island, Marín's Island, and Little Goats Island, and its native Hawaiian name is Mokuʻumeʻume. The island had an area of 334 acres (135 ha) when it was surveyed in 1825, which was increased during the 1930s to 441 acres (178 ha) with fill dredged out of Pearl Harbor by the United States Navy to accommodate battleships.
The attack on Pearl Harbor has received substantial attention in popular culture in multiple media and cultural formats including film, architecture, memorial statues, non-fiction writing, historical writing, and historical fiction. Today, the USS Arizona Memorial on the island of Oahu honors the dead. Visitors to the memorial reach it via boats from the naval base at Pearl Harbor. The memorial was designed by Alfred Preis, and has a sagging center but strong and vigorous ends, expressing "initial defeat and ultimate victory". It commemorates all lives lost on December 7, 1941.
