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 Yoke and Housing, identified by NSN 7R-1680-010927980-VH and reference number 70400-01201-044, with a quantity of one unit required for delivery FOB origin. 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. Interested vendors must provide the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, and should direct any inquiries to Casey M. Brown at casey.m.brown20.civ@us.navy.mil. Offers that do not include the required data will not be considered, and the procurement is subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement.
