The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of new manufacture spare parts, specifically aircraft doors. This is a sole source requirement, meaning that the government does not possess sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The items are critical for maintaining operational readiness and safety in military aircraft. Interested vendors must submit their proposals along with the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online, and proposals must remain valid for a minimum of 120 days following submission. For inquiries, contact Katlyn Galetto at Katlyn.m.galetto.civ@us.navy.mil or by phone at 215-697-6549.
