The Japanese aircraft carrier Akagi was originally laid down as a battle cruiser on 6 December 1920. Treaty obligations led to her conversion to aircraft carrier and she was completed on 22 April 1925. Her displacement was 28,100 tons, her length approximately 763 feet and her beam 92 feet. She was armed with 10 8-inch, four 4.7-inch and 12 4.7-inch anti-aircraft guns. In normal service she carried 30 aircraft, but was capable of taking a greater number. In the Pearl Harbor operation she carried 18 Aichi D3A1 Val Type 99 dive-bombers, 27 Nakajima B5N2 Kate Type 97 torpedo-bombers and horizontal bombers and between 18 and 27 Mitsubishi A6M Navy Type Zero Carrier Fighter Model 11s. The Akagi, under Captain Kiichi Hasegawa, was the flagship of the operation's commander, Vice-Admiral Chuichi Nagumo (Nagumo, Chuichi) and also on board were Commander Minoru Genda (Genda, Minoru), air staff officer of the First Air Fleet, Commander Mitsuo Fuchida (Fuchida, Mitsuo) who led the First Attack Wave, Lieutenant Commander Shigeharu Murata, leader of the torpedo bombers and Lieutenant Commander Shigeru Itaya, leader of the fighter aircraft. In the rough seas of the morning of 7 December preparations were made for take-off to commence at 0530 and all aircraft were launched and assembled for the flight to Pearl Harbor by 0610 hours.
