The "largest naval battle in history" is a disputed title between adherents of varying criteria which include the numbers of personnel and/or vessels involved in the naval battle, the total displacement of the vessels involved and sometimes the significance and/or implications of the battle. While battles fought in modern times are comparatively well-documented, the figures from those in pre-Renaissance era are generally believed by contemporary chroniclers to be exaggerated.
In 1975, the Austrian historian Helmut Pemsel attempted to evaluate naval battles in history by a scoring system. He assigned a score to each of four aspects of a battle as follows:
According to him, the largest naval battle ever is the Battle of Leyte Gulf, scoring 8 of a possible 9 points total, while six others tied for second at 7 points each: Salamis, the Aegates, Actium, La Hogue, Trafalgar and Jutland. [1]
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial.
The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slower type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
The United States Pacific Fleet (USPACFLT) is a theater-level component command of the United States Navy, located in the Pacific Ocean. It provides naval forces to the Indo-Pacific Command. Fleet headquarters is at Joint Base Pearl Harbor–Hickam, Hawaii, with large secondary facilities at Naval Air Station North Island, California.
The Battle of Leyte Gulf 23–26 October 1944, was the largest naval battle of World War II and by some criteria the largest naval battle in history, with over 200,000 naval personnel involved.
USS Alabama (BB-60) is a retired battleship. She was the fourth and final member of the South Dakota class of fast battleships built for the United States Navy in the 1940s. The first American battleships designed after the Washington treaty system began to break down in the mid-1930s, they took advantage of an escalator clause that allowed increasing the main battery to 16-inch (406 mm) guns, but Congressional refusal to authorize larger battleships kept their displacement close to the Washington limit of 35,000 long tons (36,000 t). A requirement to be armored against the same caliber of guns as they carried, combined with the displacement restriction, resulted in cramped ships. Overcrowding was exacerbated by wartime modifications that considerably strengthened their anti-aircraft batteries and significantly increased their crews.
USS Massachusetts (BB-59) is the third of four South Dakota-class fast battleships built for the United States Navy in the late 1930s. The first American battleships designed after the Washington treaty system began to break down in the mid-1930s, they took advantage of an escalator clause that allowed increasing the main battery to 16-inch (406 mm) guns, but refusal to authorize larger battleships kept their displacement close to the Washington limit of 35,000 long tons (36,000 t). A requirement to be armored against the same caliber of guns as they carried, combined with the displacement restriction, resulted in cramped ships, a problem that was exacerbated by wartime modifications that considerably strengthened their anti-aircraft batteries and significantly increased their crews.
USS Washington (BB-56) was the second and final member of the North Carolina class of fast battleships, the first vessel of the type built for the United States Navy. Built under the Washington Treaty system, North Carolina's design was limited in displacement and armament, though the United States used a clause in the Second London Naval Treaty to increase the main battery from the original armament of nine 14 in (356 mm) guns to nine 16 in (406 mm) guns. The ship was laid down in 1938 and completed in May 1941, while the United States was still neutral during World War II. Her initial career was spent training along the East Coast of the United States until Japan attacked Pearl Harbor on 7 December 1941, bringing the United States into the war.
Haruna was a warship of the Imperial Japanese Navy during World War I and World War II. Designed by the British naval engineer George Thurston, she was the fourth and last battlecruiser of the Kongō class, amongst the most heavily armed ships in any navy when built. Laid down in 1912 at the Kawasaki Shipyards in Kobe, Haruna was formally commissioned in 1915 on the same day as her sister ship, Kirishima. Haruna patrolled off the Chinese coast during World War I. During gunnery drills in 1920, an explosion destroyed one of her guns, damaged the gun turret, and killed seven men.
The Battle off Samar was the centermost action of the Battle of Leyte Gulf, one of the largest naval battles in history, which took place in the Philippine Sea off Samar Island, in the Philippines on October 25, 1944. It was the only major action in the larger battle in which the Americans were largely unprepared. After the previous day's fighting, the Imperial Japanese Navy's First Mobile Striking Force, under the command of Takeo Kurita, had suffered significant damage and appeared to be retreating westward. However, by the next morning, the Japanese force had turned around and resumed its advance toward Leyte Gulf. With Admiral William Halsey Jr. lured into taking his powerful Third Fleet north after a decoy fleet and the Seventh Fleet engaged to the south, the recently-landed 130,000 men of the Sixth Army were left vulnerable to Japanese attack on Leyte.
USS Gambier Bay (CVE-73) was a Casablanca-class escort carrier of the United States Navy. During the Battle off Samar, part of the overall Battle of Leyte Gulf, during a successful effort to turn back a much larger attacking Japanese surface force, Gambier Bay was sunk by naval gunfire, primarily from the battleship Yamato, taking at least 15 hits between 8:10 and 8:40. She was the only American aircraft carrier sunk by enemy surface gunfire during World War II.
Vice-Admiral Jisaburō Ozawa was an admiral in the Imperial Japanese Navy during World War II. Ozawa held several important commands at sea throughout the duration of the conflict.
Takeo Kurita was a vice admiral in the Imperial Japanese Navy (IJN) during World War II. Kurita commanded IJN 2nd Fleet, the main Japanese attack force during the Battle of Leyte Gulf, the largest naval battle in history.
USS Helm (DD-388) was a Bagley-class destroyer in the United States Navy during World War II. She was named for Rear Admiral James Meredith Helm. Helm received 11 battle stars for her World War II service in the Pacific.
Crossing the T or capping the T is a classic naval warfare tactic used from the late 19th to the mid-20th centuries in which a line of warships crosses in front of a line of enemy ships to allow the crossing line to bring all their guns to bear while it receives fire from only the forward guns of the enemy.
During World War II, at the beginning of the Pacific War in December 1941, the Imperial Japanese Navy (IJN) was the third most powerful navy in the world, and the naval air service was one of the most potent air forces in the world. During the first six months of the war, the IJN enjoyed spectacular success inflicting heavy defeats on Allied forces, being undefeated in every battle. The attack on Pearl Harbor crippled the battleships of the US Pacific Fleet, while Allied navies were devastated during Japan's conquest of Southeast Asia. Japanese Navy aircraft operating from land bases were also responsible for the sinkings of HMS Prince of Wales and HMS Repulse which was the first time that capital ships were sunk by aerial attack while underway. In April 1942, the Indian Ocean raid drove the Royal Navy from South East Asia. After these successes, the Japanese now concentrated on the elimination and neutralization of strategic points from where the Allies could launch counteroffensives against Japan's conquests. However, at Coral Sea the Japanese were forced to abandon their attempts to isolate Australia while the defeat at Midway saw them forced on the defensive. The campaign in the Solomon Islands, in which the Japanese lost the war of attrition, was the most decisive; they had failed to commit enough forces in sufficient time.
Yahagi (矢矧) was an Agano-class cruiser which served with the Imperial Japanese Navy (IJN) during World War II.
World War II saw the end of the battleship as the dominant force in the world's navies. At 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.
A fleet action is a naval engagement involving combat between forces that are larger than a squadron on either of the opposing sides. Fleet action is defined by combat and not just manoeuvring of the naval forces strategically, operationally or tactically without engaging. Most famous large naval battles in history were fleet actions. A fleet action is unrelated to participation of any formation that is a named naval fleet, and usually includes only major parts of such formations.
The United States Navy grew rapidly during its involvement in World War II from 1941–45, and played a central role in the Pacific War against Imperial Japan. It also assisted the British Royal Navy in the naval war against Nazi Germany and Fascist Italy. The U.S. Navy grew slowly in the years prior to World War II, due in part to international limitations on naval construction in the 1920s. Battleship production restarted in 1937, commencing with the USS North Carolina. The US Navy was able to add to its fleets during the early years of the war while the US was still neutral, increasing production of vessels both large and small, deploying a navy of nearly 350 major combatant ships by December 1941 and having an equal number under construction.
At the start of World War II, the Royal Navy was the strongest navy in the world, with the largest number of warships built and with naval bases across the globe. It had over 15 battleships and battlecruisers, 7 aircraft carriers, 66 cruisers, 164 destroyers and 66 submarines. With a massive merchant navy, about a third of the world total, it also dominated shipping. The Royal Navy fought in every theatre from the Atlantic, Mediterranean, freezing Northern routes to Russia and the Pacific Ocean.
