Question: The Nakajima B5N was the standard of what type of warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft?
Context: 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. HMS "Argus" was a British aircraft carrier that served in the Royal Navy from 1918 to 1944.  She was converted from an ocean liner that was under construction when the First World War began, and became the first example of what is now the standard pattern of aircraft carrier, with a full-length flight deck that allowed wheeled aircraft to take off and land.  After commissioning, the ship was heavily involved for several years in the development of the optimum design for other aircraft carriers.  "Argus" also evaluated various types of arresting gear, general procedures needed to operate a number of aircraft in concert, and fleet tactics.  The ship was too top-heavy as originally built and had to be modified to improve her stability in the mid-1920s.  She spent one brief deployment on the China Station in the late 1920s before being placed in reserve for budgetary reasons. The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea.  On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck.  The official U.S. Navy term for these vessels is "air-capable ships". 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. Sub Lieutenant Seizō Yasunori (安則 盛三 , Yasunori Seizō , died May 11, 1945) was a Japanese student who joined the Imperial Japanese Navy, and on May 11, 1945 was ordered to fly a kamikaze mission during the Battle of Okinawa near the end of World War II.  Kamikaze pilots were generally 18–20 years old, poorly trained, and flew poorly maintained aircraft.  As leader of the Navy's Kamikaze Corps 7th Showa Special Attack Squadron, he led a group of four young men to attack US Navy ships.  Yasunori led a group of six planes which departed Kanoya Air Base between 0640 and 0653 on May 11, 1945.  Yasunori dropped a 550-lb bomb and then crashed his A6M Zero into the aft portion of the flight deck of the USS "Bunker Hill" , along with his wingman, Kiyoshi Ogawa.  He and his wingman killed 393 Americans; the most devastating suicide attack in the Pacific War and wounded an additional 264.  Three-hundred fifty-two of the dead were buried at sea the next day.  The bomb tore a hole in the port side of the ship and his plane crashed onto the flight deck.  The ensuing explosion destroyed many of the planes on the deck.  His plane dragged another plane overboard.  His wingman, Kiyoshi Ogawa, crashed into the ship a few seconds later.  A third plane crashed into the sea before reaching the ship.  The fate of the remaining three planes is unknown.  His story is told in "Danger's Hour", published by Simon & Schuster on Veteran's Day, 2008. 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. The Nakajima B5N (Japanese: 中島 B5N , Allied reporting name "Kate") was the standard carrier torpedo bomber of the Imperial Japanese Navy (IJN) for much of World War II. 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. 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. 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.
