Working on some vehicles for a vehicle guide, but I'm including this, which is actually a part of Kaidan. This is the Uki class large attack submersible, Yokosuka, a heavily armed and armored military submersible - in the shape of a giant squid, with a variety of torpedo types, and a sonic pulse beam mostly to repulse giant sealife, though can be used against other targets. A crew of 16 is aboard, with 4 each 4 person rooms with 2 sets of bunkbeds per chamber and common latrine.
