It would also seem that akigi was sunk by 1 derect hit by a 1000lb bomb which hit near her central elevator and exploded in the hanger there causing explosions and fires the other bomb just missed the fan tail and exploded suposedly harmlessly but the damage from the blast damaged her ruder which jamed sometime later.Another designe fault of most japanese carriers was that the aviation fuel tanks were directly attached to the ships superstructure so bomb or shell fire hiiting it could cause theses to split or leak filling the hangars[the ventilation of the hangers was also inadiquate] with aviation fuel vapors and the subsequent explosions that followed. Her anti aircraft armament was also lacking as it was placed too low on her superstructure preventing her from being able to fire across the flight deck it also comprised of some heavy guns[at the time of her build/designe it was still envisioned that an aircraft carrier would be capable of sloging it out with another ship in a gun duel] all of her main armament was slow firing which hampered her defence from air attack. After several hours of fire fighting the ship was eventually abandoned and torpedoed by her own side, the ship sank and all we have is a compass bearing of her eventual resting place her wreak up to yet has not been identified /found [the kagi has recently been found and subsequently accorded war grave status]
I appologise in advance for any spelling grammer in the above but im no english master

Thanks for the great info Andy, this is of great interest to the Akagi builders and anyone else as well

Post 1 of the official diary build......

"Akagi was an aircraft carrier of the Imperial Japanese Navy (IJN). She was originally laid down as an Amagi-class battlecruiser at the Kure shipyard in December 1920. Construction was halted when Japan signed the Washington Naval Treaty on 6 February 1922, when the treaty placed restrictions on the construction of battleships and battlecruisers. The treaty, however, authorized conversion of two battleship or battlecruiser hulls under construction into aircraft carriers of up to 33,000 tons displacement.

The IJN had decided, following the launch of its first aircraft carrier, Hosho, to construct two larger, faster carriers for operations with major fleet units. The incomplete hulls of Amagi and Akagi were thus selected for completion as the two large carriers under the 1924 fleet construction program.

Following Japan's renunciation of the Treaty in 1936, Akagi was rebuilt and, in 1939, her original three flight decks were consolidated into a single enlarged flight deck which ran the full length of the ship. This gave a greater capacity for aircraft and an island superstructure.

Akagi's aircraft participated in the Second Sino-Japanese War in the late 1930s,. She took part in the Pearl Harbour raid in December 1941, and the invasion of Rabaul in the Southwest Pacific in January 1942. The following month her aircraft bombed Darwin, Australia. Akagi took part in the Indian Ocean raid in April 1942. This was a naval sortie by the Imperial Japanese Navy against Allied shipping and bases in the Indian ocean. The Battle of Midway is regarded as the most important naval battle of the Pacific Campaign of World War II. The US Navy inflicted severe losses on the Japanese Navy. Akagi was so irreparably damaged during this battle that on the 4th June 1942, she was scuttled by Japanese destroyers to prevent her from falling into enemy hands.

The loss of Akagi and three other IJN carriers at Midway was a crucial strategic defeat for Japan and contributed significantly to Japan's ultimate defeat in the war."
