The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of digital computer systems. This procurement is a sole source requirement, indicating that the government lacks sufficient data to contract with any source other than the current approved vendor, necessitating that interested parties submit detailed information as outlined in the NAVSUP WSS Source Approval Brochure. The items in question are critical for operational capabilities, and the selected contractor will be responsible for providing quotes that include pricing for test, training, and evaluation (TT&E) as well as estimated repair costs. Interested vendors should direct inquiries to Danielle Cutrera at Danielle.Cutrera@navy.mil or by phone at 215-697-6566, as offers lacking the required documentation will not be considered for award.
