The U.S. Army is seeking potential sources to manufacture a Door, Aircraft component (NSN 1560-01-582-6079, Part number 70207-52701-041) for Redstone Arsenal, Alabama. This is a market research notice only, not a solicitation, and no funds are available for response preparation. The government does not own the proprietary data needed for competition, so contractors must have authorization from Sikorsky Aircraft Corporation or a plan to obtain it. Responses are due by 4:30 p.m. Central Time on 11 May 2026, and performance would involve packaging and shipping to required destinations. No budget amount is specified.
