The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 12 units of the NRP, CCA, I O Module, identified by NSN 7R-7021-016028347-BL and REF NR 267A766-3. This procurement is critical as the item is flight critical, requiring Government source approval prior to contract award, and the necessary data for competitive acquisition is not available. Interested vendors must provide detailed technical data as outlined in the NAVSUP WSS Source Approval Information Brochure, and offers lacking this information will not be considered. For inquiries, interested parties can contact Dana L. Scott at dana.scott@navy.mil, with the understanding that the evaluation of source approval requests may affect the timeline for contract award.
