The Department of Defense, specifically the Department of the Navy, is seeking to procure 85 units of a power supply component, identified by NSN 7H-6120-016945070, through a presolicitation notice. This procurement is intended for supplies or services that will be solicited and negotiated with only one source, as the Government does not own the necessary data or rights to purchase or contract repair from additional sources, making it uneconomical to reverse engineer the part. The items are crucial for military operations, and the procurement process will consider proposals from all responsible sources within 45 days of the notice publication. Interested parties can contact James E. Lewis at (717) 605-7403 or via email at JAMES.E.LEWIS711.CIV@US.NAVY.MIL for further information.
