The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure eight units of the Sensor Assembly, ESM, identified by NSN 7H-2990-016110637-VN. This procurement is a total small business set-aside, and the government intends to negotiate with only one source due to the unavailability of data or rights necessary for competitive procurement. The items are crucial for military operations, and the delivery is required at the DLA Distribution facility in New Cumberland, PA. Interested parties must respond within 45 days of the notice publication, and for further inquiries, they can contact Jacob Davis at (717) 605-4237 or via email at JACOB.T.DAVIS18.CIV@US.NAVY.MIL.
