Introduction

米海軍で開発され、運用された潜水艦用魚雷兵装です。
前部6門の発射管から最大6射線、後部発射管もあわせれば、10発の魚雷で攻撃可能です。
信頼性の向上した後期型の魚雷は、日本の輸送船舶や護衛艦艇に対して圧倒的な猛威を発揮、
日本海軍そして日本全体の継戦能力を大きく削っていきました。

A torpedo weapon developed and deployed by the US Navy.
When the 6 bow tubes are combined with the stern tubes, the submarine is capable of launching a 10 torpedo spread.
The more reliable late-model torpedoes were an overwhelming menace against Japanese convoys and escort vessels.
It severely limited the ability of the Imperial Japanese Navy and Japan to prosecute the war.
