The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 42 units of a structural panel (NSN 7R-1560-017137003-V2, REF NR 901-011-439-131). This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data available does not support full and open competition. The selected supplier must demonstrate unique design capabilities and provide necessary documentation to ensure compliance with the Government's quality standards. Interested parties should contact Arianna G. Pilla at (215) 697-2198 or via email at ARIANNA.PILLA@NAVY.MIL for further details, and proposals must be submitted within 45 days of this notice.
