Fire Resistant Joiner Bulkhead

SBIR topic DON27BZ01-NV002 (U.S. Department of Defense – Navy), Phase I and II. Open to U.S. small businesses. Opens: October 28, 2026. Closes: November 25, 2026. Fire represents a grave hazard to Navy vessels. Recent fire events have propagated through joiner bulkheads and resulted in significant fire damage, which poses a substantial threat to personnel and equipment. Uncontrolled fires can propagate throughout a ship and cause extensive damage to machinery, equipment, and ship compartments; additionally, fires represent an extreme risk to ship personnel. The Navy has made numerous improvements to make ships more fire-resistant but is seeking improvement for containment of compartment-level fire events seen in recent and historical ship fires (i.e., USS OSCAR AUSTIN, USS CONYNGHAM, USS STARK, and the cruise ship Star Princess). More fire-resistant joiner bulkheads would allow damage control teams to contain and extinguish fires more easily before they could grow to threaten the ship. Innovation is needed to meet Navy goals with regard to weight, cost, fit, and performance. The Navy seeks an improved fire-resistant joiner bulkhead that would reduce the damage ships sustain during fires, as well as improve safety for the crew. Development of a fire-resistant joiner bulkhead faces several technical challenges. First, any fire-resistant joiner bulkhead must not have a significant weight increase. Given the quantity of joiner bulkheads onboard ships, any weight increase could add significant weight to the ships, which will impair and degrade ship performance. Second, the improved joiner bulkheads must not excessively exceed the width of current joiner bulkheads. Destroyers have confined spaces and for the comfort and operational capability of the crew, any new joiner bulkhead cannot greatly exceed the dimensions of the existing panels. Third, any fire-resistant joiner bulkhead must be a cost-effective solution for the Navy. In particular, the fire-resistant…
