Dover AFB - Hangar Door Plug

The 436 CONS LGC at Dover Air Force Base is conducting market research to identify sources for a custom-fitted hangar door plug system. This requirement supports the 736 Aircraft Maintenance Squadron by providing a thermal and weather seal for Hangar 714 North. The system is designed to close the gap around a C-17 fuselage when the aircraft is positioned within the larger C-5 sized aperture of the hangar doors. This notice, issued under solicitation number FA449726Q0006, covers a solution that includes a bolt-on Keder rail system for mounting, an inflatable plug made from high-strength, fire-retardant fabric, and an electric blower for inflation. The Air Force is gathering capability statements, verifying CAGE codes, and requesting recommendations for the most appropriate NAICS code for this acquisition. Performance will take place at Dover Air Force Base in Delaware. The draft Statement of Work details the technical specifications and performance metrics required for the system. Capability statements and relevant past acquisition experience are due by June 22, 2026. The 736 Aircraft Maintenance Squadron at Dover Air Force Base needs a custom hangar door plug system for Hangar 714 North. The existing hangar doors are sized for C-5 aircraft, leaving gaps when a C-17 is inside. Building 714 North at Dover Air Force Base requires an inflatable hangar door plug because the current C-5 sized doors create air gaps around C-17 aircraft. These gaps interfere with climate control and can lead to frozen pipes in winter, which stops maintenance work.
