"Hiryu (1931-32 Supplementary Programme) was a slightly enlarged and modified Soryu; the beam was increased by 1m for a 20 per cent increase in oil capacity, the protection was strengthened and the forecastle raised by a deck. The flight deck was 711ft 6in x 88ft 6in, and as in Soryu the two hangers were served by three lifts. The island was almost amidships and to port (the second and last Japanese carrier with this arrangement) where it partly balanced the two horizontally-discharging funnels to starboard. Hiryu was hit by 4 bombs from US dive-bombers in the Battle of Midway, wrecking flight deck and hangers; she had to be abandoned and scuttled, the last of the 4 Japanese carriers sunk in the Battle."
