The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of fairing assembly spare parts. This procurement is classified as a sole source requirement, indicating that the government does not possess sufficient data to consider alternative suppliers, and thus requires government source approval prior to award. The items are critical components for aircraft hydraulic, vacuum, and de-icing systems, emphasizing their importance in maintaining operational readiness. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, and can direct inquiries to Troi Lentini at 215-697-0375 or via email at troi.lentini@navy.mil.
