Rear guns unused. 10x 20cm/50 3rd Year Type 1 2x double turrets facing front 8x 8"/55 Mark 9 in dual turrets. The 20cm guns' rapid fire shook off the planes. The planes were unsteady and the fairies felt sick due to the shaking.

Removed! Akagi: Triple decker version 6x single casemates facing rearSaratoga in early configuration But I wasn't even anywhere near my limit... This isn't fair!
