Armament: 8 dual 5/40 DP, 42 25 mm AA
Aircraft: 72 (84 maximum) Concept/Program: The third pair of fleet carriers, and the last big carriers completed before WWII. They were an improved and enlarged Soryu.
Design: In general similar to the Soryu design, but more significantly larger, more heavily built, better armed and armored. They were the best Japanese carriers built. The original design had included a port-side island on one ship (as in the previous carrier pairs), but completed with starboard-side islands.
Modifications: During WWII they carried 96 25 mm AA and 6 28-barrel AA rocket launchers. Zuikaku later carried additional AA armament and had other modifications.
Operational: Usually operated together, until Shokaku was lost.
Departure from Service/Disposal: Both lost in WWII.
