The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure five units of an encoder-decoder, designated by NSN 7H-5895-016984047. This procurement is a total small business set-aside and is intended for supplies or services that will be solicited and negotiated with only one source, as it has been determined that acquiring the necessary data or rights for competitive procurement is uneconomical. The encoder-decoder is critical for military communications and operations, and the delivery is required at the DLA Distribution facility in New Cumberland, PA. Interested parties must express their interest and capability to meet the requirement within 45 days of this notice, and they can contact James E. Lewis at (717) 605-7403 or via email at JAMES.E.LEWIS711.CIV@US.NAVY.MIL for further information.
