United Colonies Navy Ship Pack: 0.4.1.6a.
Two major additions to the fleet, proving yet again that Harmonia Linea is at the forefront of Barotrauma submarine design:
The August Richard, a dedicated submersible passenger liner, and a semi-functional
Swimmer Delivery Vehicle (SDV) which, if all goes well, will be used as a parasite vehicle on UCN boats to support UCN Marines.
The August Richard (inspired by the real-life
Auguste Piccard) is my stab at a civilian boat. Up until now, everything has been military-oriented and loosely based on real designs. This one was my attempt at making an unarmed passenger boat suited to the Europa colonies during better days. It is by far the largest and most sophisticated submarine available right now; it is the first that actually caused my computer itself to lag rather than as a result of network latency. Because it's unarmed, it's best suited to non-combat missions, though if you're crafty you might be able to build weapons and attack sea creatures by hand. Otherwise, it should be interesting to see how a bunch of griefers sabotage a boat this big and robust.
The SDV is "functional" except for the part where you spawn with it and it alone. It's battery-powered and meant to shuttle armed divers to and from military subs, or even between others if multiplayer ever becomes a thing. Trying to complete missions in it is an immense challenge, so for now it's really just a showpiece.
As always, minor updates are made to older designs to keep them up to speed with new developments. Always replace these whenever a new pack is released.
