The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure four control modules under the presolicitation titled "61--CONTROL MODULE SLAV, IN REPAIR/MODIFICATION OF." The procurement involves a specific National Stock Number (NSN 7H-6110-997009491) and is limited to one source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding. These control modules are critical components of electrical control equipment, and the government intends to solicit and negotiate exclusively with the identified source. Interested parties are encouraged to express their interest and capabilities within 45 days of the notice, with all proposals considered at the government's discretion. For further inquiries, contact Abigail R. Hurlbut at (717) 605-6805 or via email at ABIGAIL.R.HURLBUT.CIV@US.NAVY.MIL.
