How the Kai-Taiho might have looked once commissioned.
Planned in 1942 as a follow-on of the IJN Taiho
BB1987, my two cents
Think:
-
(approved in the 1937 3rd supplementary program) : Shokaku & Zuikaku laid-down by late 1937/early 1938, launched by mid/late 1939, commissionned by mid/late 1941.
-
(approved in the 1939 4th program): Taiho laid-down by mid 1941, launched by early 1943, commissioned by early 1944.
G-15:
- (proposed in the 1942 program): 2 ships (n° 801 & 802) => laid-down during 1943, launched by late 1944, commissioned by mid 1945.
- (proposed in the 1942 supplementary program): 5 ships (n° 5021-5025) = laid-down by late 1943/late 1944, launched by early/late 1945, commissioned by early/late 1946.
For the 1945-1946 AA suit, don't forget that :
- The Zuikaku carry from July 1944 six 28-barreled AA rocket launchers
- The Zuiho carry from 1944 eight 28-barreled AA rocket launchers
- The Junyo carry from July 1944 six 28-barreled AA rocket launchers
- The Shinano carry by november 1944 twelve 28-barreled AA rocket launchers
- The Unryu class carry by late 1944 six 28-barreled AA rocket launchers
=> "As commissioned", your G-15 must carry eight to twelve 28-barreled AA rockets launchers
Don't forget that by 1945 :
- a new 100mm/65 Type 5 (Model 1945) gun was under design, but no guns are known to have been completed.
- a new 40mm/60 Type 5 (Model 1945) gun was under design (a japanese version of the famous 40mm Bofor).
