The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure a sole source supply of a Seal Assembly for the P-8 aircraft from The Boeing Company. The procurement involves a specific National Stock Number (NSN 1R-5330-LLF02M638-P8) and part number (411A3140-144B), with a quantity of one unit required for delivery on a Free on Board (FOB) origin basis. This Seal Assembly is critical for the operational readiness of the P-8 aircraft, and as the Original Equipment Manufacturer (OEM), Boeing is the only known source capable of providing this spare part due to the lack of available drawings or data for alternative suppliers. Interested parties must submit their capability statements to the primary contact, Jessica M. Gershenfeld, at jessica.m.gershenfeld.civ@us.navy.mil, within 15 days of this notice, with the solicitation expected to be issued around March 20, 2025, and proposals due by April 20, 2025.
