The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of four units of the NSN 1R-1560-014667305-VH, reference number 70207-26001-046, which pertains to airframe structural components. This acquisition is critical as the government lacks sufficient data to contract with any source other than the current supplier, emphasizing the importance of government source approval prior to award. The items involved are subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement, highlighting their international trade significance. Interested vendors must ensure compliance with the NAVSUP WSS Source Approval Brochure and submit the required documentation with their proposals to be considered. For inquiries, contact Casey M. Brown at (215) 697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
