The Department of Defense, specifically the Department of the Army, is seeking a contractor for the inspection and overhaul of the Control, Interface, under a presolicitation notice. The contractor will be responsible for providing all necessary services, facilities, labor, parts, materials, equipment, tools, and data to accomplish this task, with an estimated quantity ranging from 5 to 25 units. This procurement is critical as it involves a unique item for which the technical data is exclusively owned by Telephonics Corporation, making them the only approved source for this requirement. Interested parties must secure rights to the technical data package to be eligible for future procurements, and the contract is expected to be a two-year, Firm Fixed Price, Indefinite Delivery Indefinite Quantity (IDIQ) agreement. For further inquiries, interested vendors can contact Arthur Gunter at arthur.l.gunter.civ@army.mil, noting that the requirement is currently unfunded and the solicitation will not open before the estimated closing date.
