The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of two units of a specific computer digital item, identified by NSN 7R-7021-017054062-BL and reference number 344A060-552. This acquisition is critical as the government lacks sufficient data to contract with sources other than the current supplier, and the items are subject to Free Trade Agreements and require 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 Danielle M. Cutrera at danielle.cutrera@navy.mil. Proposals that do not include the required data will not be considered for award.
