The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure repair and modification services for a global positioning system component identified by NSN 7R-6605-017222726-RQ. The procurement involves a quantity of one unit, with delivery terms set as FOB Origin, and the government intends to negotiate exclusively with one source due to the flight-critical nature of the item and the lack of sufficient technical data for competitive procurement. Interested parties must demonstrate their capability and interest in fulfilling this requirement, with proposals due within 45 days of the notice publication, and must comply with the source approval process outlined in the NAVSUP WSS Source Approval Information Brochures. For further inquiries, interested vendors can contact Carmelena C. Oldroyd at (215) 697-2606 or via email at Carmelena.Oldroyd@navy.mil.
