Introduction

20cm級の砲を一基三門に集約したベーシックでありながら、大火力を備えた主砲兵装です。米海軍の条約型重巡Pensacola級やNorthampton級の主兵装として運用されました。

Developed by the United States Navy as the main gun of their treaty heavy cruisers, it was equipped on the heavy cruisers in a triple mount. It possesses great firepower even though it is just a basic mounting of three 20cm guns in a single turret. It was used as the main gun of the United States Navy's Pensacola and Northampton-class treaty heavy cruisers.
