Modification

By 1943 she had 42 25mm guns and 6 13mm/76 machine guns.

In June 1944 the armament was increased to 61 25mm guns, 28 13mm guns, 6x28 rocket launchers, and 6 depth charges and the flight deck was extended to 670' (204.2m).

1944: Type 21 radar added.


The Ryuho was converted from submarine tender Taigei, which was part of Japan's "shadow fleet" of auxiliaries designed for rapid conversion to carriers in the event of war. She was recommissioned as a flush-deck light carrier on 28 November 1942. She proved unsuccessful, having poor internal subdivision and a weak hull, and she remained underpowered even after her original diesel engines were replaced with destroyer turbines.

Her conversion was delayed by bomb damage inflicted by the Doolittle raiders, which was possibly the most concrete material damage inflicted by that raid.

Ryuho was crippled by aircraft on 19 March 1945 at Kure and not repaired.
