World War II
Nakajima B6N
The Nakajima B6N "Tenzan" (Japanese: 中島 B6N 天山—"Heavenly Mountain", Allied reporting name: "Jill") was the Imperial Japanese Navy's standard carrier-borne torpedo bomber during the final years of World War II and the successor to the B5N "Kate".
 Due to its protracted development, a shortage of experienced pilots and the United States Navy's achievement of air superiority by the time of its introduction, the B6N was never able to fully demonstrate its combat potential.
Aircraft carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft.
 Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations.
 Aircraft carriers are expensive to build and are critical assets.
 Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighter planes, strike aircraft, helicopters, and other types of aircraft.
 While it is possible to launch heavier aircraft such as fixed-wing gunships and bombers (it has been done) from aircraft carriers, it is virtually impossible to land them.
Japanese aircraft carrier Hōshō
Hōshō (鳳翔 , literally "flying phoenix") was the world's first commissioned ship that was designed and built as an aircraft carrier, and the first aircraft carrier of the Imperial Japanese Navy (IJN).
 Commissioned in 1922, the ship was used for testing carrier aircraft operations equipment, techniques, such as take-offs and landings, and carrier aircraft operational methods and tactics.
 The ship provided valuable lessons and experience for the IJN in early carrier air operations.
 "Hōshō"'s superstructure and other obstructions to the flight deck were removed in 1924 on the advice of experienced aircrews. List of aircraft carriers
This list of aircraft carriers contains aircraft carriers listed alphabetically by name.
 An aircraft carrier is a warship with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft, that serves as a seagoing airbase. Japanese aircraft carrier Akagi
Akagi (Japanese: 赤城 "Red Castle") was an aircraft carrier built for the Imperial Japanese Navy (IJN), named after Mount Akagi in present-day Gunma Prefecture.
 Though she was laid down as an "Amagi"-class battlecruiser , "Akagi" was converted to an aircraft carrier while still under construction to comply with the terms of the Washington Naval Treaty.
 The ship was rebuilt from 1935 to 1938 with her original three flight decks consolidated into a single enlarged flight deck and an island superstructure.
 The second Japanese aircraft carrier to enter service, and the first large or "fleet" carrier, "Akagi" figured prominently in the development of the IJN's new carrier striking force doctrine that grouped carriers together, concentrating their air power.
 This doctrine enabled Japan to attain its strategic goals during the early stages of the Pacific War from December 1941 until mid-1942. Japanese aircraft carrier Taihō
Taihō (大鳳 ) (meaning Great Phoenix), was an aircraft carrier of the Imperial Japanese Navy during World War II.
 Possessing heavy belt armor and featuring an armored flight deck (a first for any Japanese aircraft carrier), she represented a major departure in Japanese aircraft carrier design and was expected to not only survive multiple bomb, torpedo, or shell hits, but also continue fighting effectively afterwards. List of sunken aircraft carriers
With the advent of heavier-than-air flight, the aircraft carrier has become a decisive weapon at sea.
 In 1911 aircraft began to be successfully launched and landed on ships with the successful flight of a Curtiss Pusher aboard the USS "Pennsylvania".
 The British Royal Navy pioneered the first aircraft carrier as floatplanes, as flying boats under performed compared to traditional land based aircraft.
 The first true aircraft carrier was the HMS "Argus" , launched in late 1917 with a complement of 20 aircraft, a flight deck of 550 ft and 68 ft wide.
 The last aircraft carrier sunk in wartime was the Japanese carrier "Amagi", in Kure Harbour in July 1945.
 The greatest loss of life was the 2,046 killed on the "Akitsu Maru"—a converted passenger liner with a small flight deck, carrying the Imperial Japanese Army's 64th Infantry Regiment. List of aircraft carriers in service
This is a list of aircraft carriers which are currently in service, reserve, under construction, or being rebuilt.
 An aircraft carrier is a warship with a full-length flight deck, hangar and facilities for arming, deploying, and recovering aircraft.
 The list only refers to the status of the ship, not availability or condition of an air wing.
 This includes helicopter carriers and amphibious assault ships, which are vessels whose primary purpose is to carry, arm, deploy, and recover aircraft. HMS Furious (47)
HMS "Furious" was a modified "Courageous"-class battlecruiser built for the Royal Navy (RN) during the First World War.
 Designed to support the Baltic Project championed by the First Sea Lord of the Admiralty, Lord Fisher, the ship was very lightly armoured and designed to be armed with only two heavy guns (18-inch), one forward and one aft, plus a number of lesser guns.
 "Furious" was modified and became an aircraft carrier while under construction.
 Her forward turret was removed and a flight deck was added in its place, such that aircraft had to manoeuvre around the superstructure to land.
 Later in the war, the ship had her rear turret removed and a second flight deck installed aft of the superstructure, but this was less than satisfactory due to air turbulence.
 "Furious" was briefly laid up after the war before she was reconstructed with a full-length flight deck in the early 1920s. Kiyoshi Ogawa
Kiyoshi Ogawa (Japanese: 小川 清 "Ogawa Kiyoshi", October 23, 1922 – May 11, 1945) was a Japanese naval aviator ensign (少尉 ) of the Imperial Japanese Navy during World War II.
 As a kamikaze pilot, Ensign Ogawa's final action took place on May 11, 1945, during the Battle of Okinawa.
 Piloting a bomb-laden Mitsubishi Zero fighter during Operation Kikusui No. 6, Ogawa at the age of 22 flew through American anti-aircraft fire and attacked the U.S. Navy aircraft carrier USS "Bunker Hill" .
 He dropped a 550 lb bomb, never pulled out of the dive, and crashed deliberately into the flight deck near the control tower of the American aircraft carrier.
 The bomb penetrated "Bunker Hill's" flight deck and exploded, gasoline fires flamed up and several explosions took place when re-armed and re-fueled planes on deck exploded and caught fire.
 Nearly 400 American sailors died with Ogawa and the ship was disabled for the remainder of the war.
