The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of 16 units of the Spring Cover (NSN 1R-1680-016870343-BL, REF NR 4166AS0533-103). This acquisition is critical as the government lacks sufficient data to contract with sources other than the current supplier, 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 can direct inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
