USS "Wasp" (CV-7) was a United States Navy aircraft carrier commissioned in 1940 and lost in action in 1942.
 She was the eighth ship named  , and the sole ship of a class built to use up the remaining tonnage allowed to the U.S. for aircraft carriers under the treaties of the time.
 As a reduced-size version of the "Yorktown"-class aircraft carrier hull, "Wasp" was more vulnerable than other United States aircraft carriers available at the opening of hostilities.
 "Wasp" was initially employed in the Atlantic campaign, where Axis naval forces were perceived as less capable of inflicting decisive damage.
 After supporting the occupation of Iceland in 1941, "Wasp" joined the British Home Fleet in April 1942 and twice ferried British fighter aircraft to Malta.
 "Wasp" was then transferred to the Pacific in June 1942 to replace losses at the battles of Coral Sea and Midway.
 After supporting the invasion of Guadalcanal, "Wasp" was sunk by the Japanese submarine "I-19" on 15 September 1942.
The "Iowa"-class battleships were a class of six fast battleships ordered by the United States Navy in 1939 and 1940 to escort the Fast Carrier Task Forces that would operate in the Pacific Theater of World War II.
 Four were completed, two more were laid down but canceled in August 1945, at war's end, and both hulls were scrapped in 1958.
 Like other third-generation American battleships, the "Iowa"s followed the design pattern set forth in the preceding "North Carolina"-class and "South Dakota"-class battleships, which emphasized speed in addition to secondary and anti-aircraft batteries.
 Based on wartime experience, they were to serve as fast escorts for "Essex"-class aircraft carrier s.
The two "Hiyō"-class aircraft carriers (飛鷹型航空母艦 , Hiyō-gata kōkūbokan ) were built for the Imperial Japanese Navy (IJN) during World War II.
 Both ships of the class, "Hiyō" and "Junyō", were originally laid down as luxury passenger liners before being acquired by the IJN for conversion to aircraft carriers in 1941.
 "Junyō" was the first of the sister ships to be completed in May 1942 and the ship participated in the invasion of the Aleutian Islands the following month.
 Both ships participated in several battles during the Guadalcanal Campaign in late 1942.
 Their aircraft were disembarked several times and used from land bases in a number of battles in the South West Pacific.
The "Unryū"-class aircraft carriers (雲龍型航空母艦 , Unryū-gata Kōkūbokan ) were World War II Japanese aircraft carriers.
 16 carriers were planned under the Maru Kyū Programme (Ship #302 in 1941) and the Kai-Maru 5 Programme (#5001–5015 in 1942).
 However, only 3 of the Unryū class carriers were completed.
The "Kiev"-class aircraft carriers (also known as Project 1143 or as the Krechyet (Gyrfalcon) class) were the first class of fixed-wing aircraft carriers built in the Soviet Union.
The "Chitose"-class aircraft carriers (千歳型航空母艦 , Chitose-gata kōkūbokan ) were a class of two seaplane tenders, later converted to light aircraft carriers, of the Imperial Japanese Navy during World War II.
 Under the terms of the Washington Naval Treaty, the total tonnage of Japan's naval vessels was limited by class.
 The "Chitose"-class ships were built as seaplane tenders, designed to make the conversion to aircraft carriers relatively easy.
 They served as seaplane tenders during the early part of the Pacific War.
 After the Battle of Midway, they were converted into light aircraft carriers.
 Both ships participated in the Battle of the Philippine Sea and both were sunk in the Battle of Leyte Gulf.
King Neptune (May 16, 1942 – May 14, 1950) was a pig used by a United States Navy recruiter to raise $19 million in war bonds (over $250 million in 2012 adjusted for inflation ) for the construction of the "Iowa"-class battleship "Illinois" between 1942 and 1946.
The "Clemenceau"-class aircraft carriers are a pair of aircraft carriers which served in the French Navy from 1961 until 2000.
 From 2000 until 2017 one served with the Brazilian Navy as "São Paulo" .
 The "Clemenceau" class was France's first successful aircraft carrier design after World War II and was the backbone of the French Fleet for the duration of its forty years of service.
The "Lexington"-class aircraft carriers were a pair of aircraft carriers built for the United States Navy (USN) during the 1920s.
 The ships were built on hulls originally laid down as battlecruisers after World War I, but under the Washington Naval Treaty of 1922, all U.S. battleship and battlecruiser construction was cancelled.
 The Treaty, however, allowed two of the unfinished ships to be converted to carriers.
 They were the first operational aircraft carriers in the USN and were used to develop carrier aviation tactics and procedures before World War II in a series of annual exercises.
The "Saipan"-class aircraft carriers were a class of two light carriers "Saipan" (CVL-48) and "Wright" (CVL-49) built for the United States Navy during World War II.
 Like the nine "Independence"-class light carriers, they were based on cruiser hulls.
 However, they differed from the earlier light carriers in that they were built from the keel up as carriers, and were based on heavy rather than light cruiser hulls.
 Completed too late for the war, they served as carriers until the mid-1950s, then were converted into a command ship ("Wright") and a major communications relay ship ("Saipan") in the late 1950s, and in those roles served until 1970.
 They were both scrapped in 1980.
