They can also be equipped on light cruisers, as there technically isn't a naval treaty in the Kancolle universe. However in the interview with Japanese Febri magazine the line appeared as "20.3cm guns equipped on light cruisers will not be able to show 100% efficiency", although there is no data to prove the fact.


条約上限一杯の8インチ(20.3cm)のこの砲は、中距離での砲撃戦はもちろん、 夜戦のような近距離での殴り合いでも十分にその威力を発揮します。

"The 20.3cm twin gun was the main armament of heavy cruisers. Calibered at 8 inches (20.3cm), the limit of naval treaty, it works extremely well in both day and night battle, from point-blank to mid-range firing. It also works limitedly as anti-air weapon."

Equipped as standard main guns for all Japanese heavy cruisers. Initially it was developed as the 20.0cm single mount (as seen on early Furutaka-class cruisers) but was later modified to fit 8.0 inches (20.3cm). "
