I'm a feder-allergic and I blame the Klingon for not having smashed the Federation in time to save us from Star Trek serials.
Thanks Paolo some how I knew you would be answering this. Makes sense!
I tell you one more thing. If you compare the Shoho vs Zuiho you will note a difference. The reply that the Shoho DF is underestimated and the correct one is the Zuiho. The Japanese report on its sinking reports that it was hit by 3/4 torpedoes and 8/10 bombs, that makes her a hard to sink ship. As long as it regards the AAF, they are correct so since between Coral Sea and the Guadalcanal campaign the Zuiho AA suite was improved.
