The galley consists of one small microwave. Sea Shadow was designed for short duration missions, typically 3-5 days apart from HMB-1. But even with a normal crew of 12, the galley was limited. The food was very basic, one crew member commented, "We survived the food, but that was it."
The ladder up leads to a hatch in the overhead leading to the main deck. Forward the door leads to the bridge. Curtains were available to allow crew to move to and from the bridge without leaking light.
