The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking a sole source procurement for 10 units of a specific aircraft equipment item, identified by NSN 7R-1680-015728130-CB and reference number 6120-0500-001. 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 ensure compliance with the NAVSUP WSS Source Approval Brochure and submit all required documentation with their proposals to be considered; inquiries can be directed to Danielle M. Cutrera at danielle.cutrera@navy.mil.
