The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for a sole source contract for a single disk brake (NSN 7R-1630-017023919-H5, REF NR 06650-04875-106) with a quantity of one unit, to be delivered FOB origin. This procurement is critical as the government lacks sufficient data to engage other sources, emphasizing the importance of the current supplier's capabilities in providing this specific aircraft wheel and brake system component. Interested vendors must obtain Government Source Approval prior to award, and proposals must include the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online. For further inquiries, potential bidders can contact Casey M. Brown at (215) 697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
