UC-5, The imperial submarine.

Inspired by historical designs from an ancient earth submarine, the UC-5 is an invention of necessity. Little space is wasted aboard this cramped vessel, but don't be fooled by its size. It is more than capable of doing the job.

Features: -Two coilguns, each with about 180 degrees of vision top and bottom, with a railgun towards the front for larger foes.

-Complex automated rear airlock. Won't let water in, but will open if the interior is already flooded. In the case of an emergency, the door can be dewired to function normally.

-Zero security doors allows for full access for repairs; Hazardous materials are behind tiered safes, depending on security clearance.

-Compact size, about the size of a dugong. Should allow it to fit inside most small passages.

-Easy-flow design. The majority of the ship is a hallway, making traversing the ship relatively easy and quick.

-Fabricators and deconstructors are present, with lots of storage space.

-Water alarms sound when a room is fully flooded
