The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source contract to procure nine units of the LINK ASSEMBLY, UPPER, identified by NSN 7R-1615-012212614-VH and reference number 70104-08021-044. This procurement is critical as the government lacks sufficient data to engage alternative sources, emphasizing the importance of Government Source Approval prior to award. The items are subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement, highlighting their international trade significance. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and direct any inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
