I-315 Submarine

Continuation of the evolution of the I-305 design. The I-315 class is bigger and more powerful than the I-310 class, being similar in size to the I-400 and I-402 classes. The I-315 was designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels and it is the first patrol submarine of the Imperial Japanese Navy that does not carry any kind of defensive or offensive guns, relying solely on the deadly Type 3 torpedoes and the ability to remain submerged for long periods of time.
