The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 45 units of the Cylinder Hoist Assembly and other replacement parts. This procurement is limited to one source due to the Government's lack of ownership of the necessary data for competitive sourcing, making it uneconomical to reverse engineer the part. The items are critical for marine hardware applications, and interested parties are encouraged to express their capabilities within 45 days of this presolicitation notice. For further inquiries, potential vendors can contact James E. Lewis at (717) 605-7403 or via email at JAMES.E.LEWIS5@NAVY.MIL.
