The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a Locator Pin Assembly (NSN 1R-9999-LLF02N446-SX, REF NR 449-240-005-159) with a quantity of one unit. This item is classified as flight critical, necessitating Government source approval prior to contract award, as the available technical data is insufficient for open competition. Interested vendors must provide detailed documentation as outlined in the NAVSUP Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the understanding that awards may proceed based on Fleet support needs if source approval cannot be processed in time. For inquiries, contact Jake Kucowski at (215) 679-2012 or via email at JAKE.KUCOWSKI.CIV@US.NAVY.MIL.
