ww2dbaseIn Dec 1941, submarine depot ship Taigei was decommissioned and drydocked at the Yokosuka Naval Shipyard, Japan, undergoing a conversion to become an aircraft carrier. In Apr 1942, she was the only ship to become damaged by the Doolittle Raiders (500-pound bomb on the bow, plus several incendiary bomb hits). When the ship re-emerged on 30 Nov 1942, the carrier was re-christened Ryuho. The newly converted carrier joined the 3rd Fleet. In Dec 1942, she ferried 20 light bombers with their crews from Japan to Truk. At 0910 hours on 12 Dec, she was hit by a torpedo on the starboard side from the American submarine Drum, forcing her to spend time at Yokosuka for repairs. On 13 Mar 1943, she began a series of ferrying missions between various Japanese bases in from Singapore to the Central Pacific Ocean. In May 1944, she joined the Combined Fleet at Tawi Tawi, Philippine Islands. In the following month, she participated in the Battle of the Philippine Sea, launching aircraft against US Navy Task Force 58 and nearly lost all of them. At 0610 hours on the next day, 20 Jun, her group was attacked by TBF Avenger torpedo bombers from the carrier USS Enterprise, damaging her from near misses. Deprived of most of her aircraft after the battle, she returned to Japan for patrol and training missions. On 25 Oct 1944, she returned to ferrying duty by transporting aircraft from Sasebo, Japan to Keelung, Taiwan. Between 7 and 15 Nov, she was briefly the flagship of Admiral Jisaburo Ozawa. On 31 Dec 1944, she set sail for Taiwan once again with a load of 58 Ohka special attack aircraft, accompanied by 9 empty oil tankers bound for Singapore, escorted by destroyers Hamakaze, Isokaze, Yukikaze, Shigure, and Hatakaze. After successfully disembarking the aircraft, she was found by 12 American TBF Avenger aircraft, but none scored a hit while Ryuho's anti-aircraft guns shot down one of the torpedo bombers. She departed for Japan on 12 Jan with Isokaze in escort, arriving at Kure, Japan on 18 Jan. This was to be the last Japanese carrier mission outside Japanese waters.
ww2dbaseOn 19 Mar, Ryuho was attacked near Kure, receiving three 500-pound bomb hits and two 140-millimeter rocket hits. Her flight deck was severely damaged between her two elevators, the No. 1 boiler was punctured, the stern settled two meters into the water, and a fire broke out. 20 were killed and 30 were wounded in the attack. She made it to Kure on 1 Apr, but since Japan no longer had aircraft to operate from carriers, it was decided that she was not to be repaired. After the war, she was scrapped in 1946.

著名二戰名言
"Among the men who fought on Iwo Jima, uncommon valor was a common virtue."Fleet Admiral Chester W. Nimitz, 16 Mar 1945
5 Aug 2012 12:12:07 PM
I am interested in the aircraft carrier Ryuho. In her first conversion, she had a shorter flight deck. Later it was extended. Did this take place before or after the Turkey Shoot? If you know, can you list your sources as well? Thank you.
