Matsushima II submarineEdit
Matsushima II is noticeably bigger than the original Matsushima and has completely different appearance. It actually looks more like some futuristic spaceship placed underwater than a conventional submarine. That said, she is still not autonomous and needs to be manually controlled.
Also, unlike her predecessor, Matsushima II is armed. She has at least 16 torpedo tubes, numerous missile launchers, and carries several dozens of Corrosive Warhead Torpedoes that have been salvaged from Hyuuga's husk. In addition to that, Matsushima can synchronize with the Auxiliary Super-Graviton Cannon ships and fire a Super-Graviton Cannon using them.
According to Hyuuga, Matsushima's hull isn't made entirely from nanomaterials and will start breaking apart if the submarine exceeds 1500m depths.
After the battle between I-401 and Kongou's fleet heats up, Gunzou decides to use Matsushima II for offense and distraction. While this plan kinda works - he was able to neutralize the hinting fleet, sinking Kongou was able to critically damage Matsushima II in retaliation. And, when that wasn't enough to outright destroy it, Kongou rams it with her prow (the rest of her hull is debris at that point).
