end bulkhead

There were twin sliding doors in the end bulkheads, with a concealed chain over the top so that they opened and closed together.

The lifts were placed outside the hangar, at either end, with access through sliding armoured doors in the end bulkheads.

Two of the benches (those attached to the end bulkheads) were fixed and the other seven benches were tip-over.

As all U.S. battleships already had thick armor end bulkheads, this gave the magazines, machinery and control areas one continuous armored box.

Split barges serve the same purpose, but instead of a door in the hull's bottom, the hull of the whole barge splits longitudinally between the end bulkheads.

Letters and numbers were originally painted only on the end bulkheads and doors, both of which could be removed as traffic dictated, and this made wagon identification difficult until the decals were transferred to the underframes of each wagon.

Its warren of cabins, cramped day rooms, machinery compartments, stairwells, and labyrinthine passageways reminded him more of a submarine than anything else, Massey thought as he lounged on his bunk and contemplated the view of Earth's disk being presented on the screen built into the cabin's end bulkhead.
