The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of 10 units of aircraft equipment, specifically NSN 7R-1680-015728130-CB, REF NR 6120-0500-001. 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. The items involved are subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement, highlighting their significance in international trade compliance. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and can direct inquiries to Danielle M. Cutrera at danielle.cutrera@navy.mil or by phone at (215) 697-6566.
