The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of Cylinder Assembly, A, as part of a Foreign Military Sales (FMS) spares purchase. This requirement is classified as a sole source procurement, indicating that the government does not possess sufficient data to contract with any source other than the current supplier, necessitating Government Source Approval prior to award. The items are critical components for aircraft hydraulic, vacuum, and de-icing systems, underscoring their importance in maintaining operational readiness. Interested vendors must submit their proposals along with the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For further inquiries, potential bidders can contact Troi Lentini at 215-697-0375 or via email at troi.lentini@navy.mil.
