The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the manufacture of spare parts identified as Control Assembly, HY. This procurement is a sole source requirement, necessitating Government Source Approval prior to award, as the Government lacks sufficient data to contract with other sources. The items are critical for shipboard systems that enable the launch and recovery of aircraft, emphasizing the importance of quality and compliance with stringent manufacturing and testing standards. Interested vendors must submit proposals along with the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, and can direct inquiries to Alexis Healy at alexis.k.healy.civ@us.navy.mil or by phone at 215-697-1143. Proposals must remain valid for a minimum of 120 days following submission.
