The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead. It was also the first military battle between two aircraft carriers.
Zuikaku was the second and last Shōkaku-class aircraft carrier built for the Imperial Japanese Navy (IJN) shortly before the beginning of the Pacific War. Zuikaku was one of the most modern Japanese aircraft carriers when commissioned, and saw successful action throughout numerous battles during the Pacific War.
USS Yorktown (CV-5) was an aircraft carrier that served in the United States Navy during World War II. Named after the Battle of Yorktown in 1781, she was commissioned in 1937. Yorktown was the lead ship of the Yorktown class, which was designed on the basis of lessons learned from operations with the converted battlecruisers of the Lexington class and the smaller purpose-built USS Ranger.
USS Lexington (CV-2), nicknamed "Lady Lex", was the name ship of her class of two aircraft carriers built for the United States Navy during the 1920s. Originally designed as a Lexington-class battlecruiser, she was converted into one of the Navy's first aircraft carriers during construction to comply with the terms of the Washington Naval Treaty of 1922, which essentially terminated all new battleship and battlecruiser construction. The ship entered service in 1928 and was assigned to the Pacific Fleet for her entire career. Lexington and her sister ship, Saratoga, were used to develop and refine carrier tactics in a series of annual exercises before World War II. On more than one occasion these included successfully staged surprise attacks on Pearl Harbor, Hawaii. The ship's turbo-electric propulsion system allowed her to supplement the electrical supply of Tacoma, Washington, during a drought in late 1929 to early 1930. She also delivered medical personnel and relief supplies to Managua, Nicaragua, after an earthquake in 1931.
The second USS Astoria (CL/CA-34) was a New Orleans-class cruiser of the United States Navy that participated in both the Battle of the Coral Sea and the Battle of Midway, but was then sunk in August 1942, at the Battle of Savo Island. Astoria was the first New Orleans-class cruiser to be laid down but launched after and received a hull number higher than the lead ship New Orleans.
USS Sims (DD-409) was the lead ship of her class of destroyers in the United States Navy during World War II. She was the first ship to be named for William Sims, an Admiral who pushed for the modernization of the Navy.
The bombing of Rabaul in November 1943 was an air attack conducted by the Allies of World War II upon a cruiser force at the major Japanese base of Rabaul. In response to the Allied invasion of Bougainville, the Japanese had brought a strong cruiser force down to Rabaul from Truk, their major naval base in the Caroline Islands about 800 miles north of Rabaul in preparation for a night engagement against the Allied supply and support shipping. Allied carrier- and land-based planes attacked the Japanese ships, airfields, and port facilities on the island of New Britain to protect the Allied amphibious invasion of Bougainville. As a result of the Rabaul raids, the Japanese naval forces could no longer threaten the landings. The success of the raid began to change the strongly held belief that carrier-based air forces could not challenge land-based air forces.
The New Guinea campaign of the Pacific War lasted from January 1942 until the end of the war in August 1945. During the initial phase in early 1942, the Empire of Japan invaded the Territory of New Guinea on 23 January and Territory of Papua on 21 July and overran western New Guinea beginning on 29 March. During the second phase, lasting from late 1942 until the Japanese surrender, the Allies—consisting primarily of Australian forces—cleared the Japanese first from Papua, then New Guinea, and finally from the Dutch colony.
Operation Mo or the Port Moresby Operation was a Japanese plan to take control of the Australian Territory of New Guinea during World War II as well as other locations in the South Pacific. The goal was to isolate Australia and New Zealand from the Allied United States.
The invasion of Tulagi, on 3–4 May 1942, was part of Operation Mo, the Empire of Japan's strategy in the South Pacific and South West Pacific Area in 1942. The plan called for Imperial Japanese Navy troops to capture Tulagi and nearby islands in the British Solomon Islands Protectorate. The occupation of Tulagi by the Japanese was intended to cover the flank of and provide reconnaissance support for Japanese forces that were advancing on Port Moresby in New Guinea, provide greater defensive depth for the major Japanese base at Rabaul, and serve as a base for Japanese forces to threaten and interdict the supply and communication routes between the United States and Australia and New Zealand.
The Battle of Wau, 29 January – 4 February 1943, was a battle in the New Guinea campaign of World War II. Forces of the Empire of Japan sailed from Rabaul and crossed the Solomon Sea and, despite Allied air attacks, successfully reached Lae, where they disembarked. Japanese troops then advanced overland on Wau, an Australian base that potentially threatened the Japanese positions at Salamaua and Lae. A race developed between the Japanese moving overland, hampered by the terrain, and the Australians, moving by air, hampered by the weather. By the time the Japanese reached the Wau area after a trek over the mountains, the Australian defenders had been greatly reinforced by air. In the battle that followed, despite achieving tactical surprise by approaching from an unexpected direction, the Japanese attackers were unable to capture Wau.
The invasion of Salamaua–Lae, called Operation SR by the Japanese, was an operation by Imperial Japanese forces to occupy the Salamaua–Lae area in the Territory of New Guinea during the Pacific campaign of World War II. The Japanese invaded and occupied the location in order to construct an airfield and establish a base to cover and support the advance of Japanese forces into the eastern New Guinea and Coral Sea areas. As the Japanese arrived, the tiny Australian garrison in the region retreated and did not oppose the invasion.
The action off Bougainville was a naval and air engagement on the South Pacific Theater of World War II near Bougainville, Papua New Guinea on 20 February 1942. A United States Navy aircraft carrier task force on its way to raid the Imperial Japanese military base at Rabaul, New Britain was attacked by a force of land-based bombers of the Imperial Japanese Navy. The US task force was commanded by Admiral Wilson Brown and the Japanese aircraft forces were under the command of Eiji Gotō.
Task Force 17 (TF17) was an aircraft carrier task force of the United States Navy during the Pacific Campaign of World War II. TF17 participated in several major carrier battles in the first year of the war.
The ANZAC Area, also called the ANZAC Command, was a short-lived naval military command for Allied forces defending the northeast approaches to Australia including the Fiji Islands, New Hebrides, and New Caledonia during the early stages of the Pacific Campaign of World War II. The command was created on 27 January 1942. United States Navy Vice Admiral Herbert Fairfax Leary commanded the force. The force co-existed with the Allied ABDA command which was charged with defending Allied colonial territories in Southeast Asia and the Southwest Pacific from Imperial Japanese aggression.
The Tenyo Maru was a 6,843-gross register ton passenger cargo ship built by Mitsubishi, Nagasaki for Toyo Kisen Kabushiki Kaisha in 1935. She was chartered to Mitsui and plied the New York route until she was requisitioned on 9 September 1941 by the Imperial Japanese Navy during World War II and converted at the Harima shipyard to a minelayer, which was completed on 31 October 1941.
The neutralisation of Rabaul was an Allied campaign to render useless the Imperial Japanese base at Rabaul in eastern New Britain, Papua New Guinea. Japanese forces landed on Rabaul on 23 January 1942, capturing it by February 1942, after which the harbor and town were transformed into a major Japanese naval and air installation. The Japanese heavily relied on it, using it as a launching point for Japanese reinforcements to New Guinea and Guadalcanal. Throughout the Solomon Islands campaign, neutralizing Rabaul became the primary objective of the Allied effort in the Solomons.
Stanley Winfield "Swede" Vejtasa was a United States Navy career officer and World War II flying ace. During the Battle of the Santa Cruz Islands, he was credited with downing seven Japanese aircraft in one mission, becoming an "ace in a day".
Naval historians such as Evan Mawdsley, Richard Overy, and Craig Symonds concluded that World War II's decisive victories on land could not have been won without decisive victories at sea. Naval battles to keep shipping lanes open for combatant's movement of troops, guns, ammunition, tanks, warships, aircraft, raw materials, and food largely determined the outcome of land battles. Without the Allied victory in keeping shipping lanes open during the Battle of the Atlantic, Britain could not have fed her people or withstood Axis offensives in Europe and North Africa. Without Britain's survival and without Allied shipments of food and industrial equipment to the Soviet Union, her military and economic power would likely not have rebounded in time for Russian soldiers to prevail at Stalingrad and Kursk.
A series of operations by American aircraft carriers was undertaken in the first half of 1942 in response to the Japanese attack on Pearl Harbor. Six American air-naval operations conducted from January to the end of April 1942 were aimed at harassing Japan during the height of the Japanese offensive in Southeast Asia, improving the morale of the American forces, which had deteriorated after the attack on Pearl Harbor, and also showing Japan that despite all the defeats of the Allies during this time, the United States Navy could carry out effective strikes. The last of these raids directly accelerated the Japanese attack on Midway, which had strategic consequences for the Pacific War.
