The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking a sole source procurement for a shaft assembly, specifically identified by NSN 7R-3040-016891325-H5, with a quantity of one unit required for delivery FOB origin. 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 contact Lauren N. Phillips at lauren.n.phillips@navy.mil for further details and must provide the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure to be considered for this opportunity.
