A Japanese carrier's anti-aircraft defense depended on attack geometry

How formidable was the Japanese carrier's late-war anti-aircraft battery?

It was respectable but not overwhelming, and its effectiveness varied sharply against torpedo bombers, dive bombers, and rocket attacks from different bearings.

The late-war Japanese carrier battery is judged reasonable for its era. Arcs, altitude, bearing, and attack profile determined how much of it could engage: the same ship might be formidable to a torpedo bomber, merely adequate against a dive bomber, and poorly placed against rockets. A raw gun total cannot capture those differences.
