The Department of Defense, through the NAVSUP Weapon Systems Support, is seeking a sole source procurement for nine units of a specific computer subassembly, identified by NSN 7R-7021-016689481-BL and reference number 35579-007, from Lockheed Martin. This procurement is critical as the government lacks sufficient data to contract with other sources, and the items are subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement. Interested firms that believe they can meet the requirements must contact Dana L. Scott at dana.scott@navy.mil to express their interest and must provide the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure. Proposals that do not include the required data will not be considered for award.
