The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 149 units of a specific switch identified by NSN 7H-5930-015462158. The procurement is intended to be negotiated with a single source due to the government's determination that acquiring the necessary data or rights for competitive procurement is uneconomical, and reverse engineering is not feasible. This switch is critical for military applications, and the government is not utilizing the policies for commercial item acquisition in this solicitation. Interested parties are encouraged to express their interest and capabilities within 45 days of the notice, with all inquiries directed to James E. Lewis at (717) 605-7403 or via email at JAMES.E.LEWIS5@NAVY.MIL.
