FIELD: transport.

SUBSTANCE: invention relates to ship building, namely, to strong hulls of submarines, submarine apparatuses. Proposed bulkhead comprises bulkhead web, bulkhead door coaming at door centre, rigid thrust ring to fasten bulkhead to strong hull. Bulkhead web is made from set of bearing composite layers bound by binding interlayers, and features zero curvature.
