The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source contract for the procurement of a Cowl Assembly, Left Hand, Aircraft (NSN 7R-1680-016063550-CB, REF NR 70302-22141-054) with a quantity of one unit, to be delivered FOB Origin. This acquisition is critical as the government lacks sufficient data to engage alternative sources, emphasizing the importance of the current supplier's unique capabilities. The items involved are subject to Free Trade Agreements and require Government Source Approval prior to award, necessitating that non-approved sources submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure. Interested parties should direct inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil, as offers lacking the necessary data will not be considered for award.
