The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure eight units of a specific cartridge for repair or modification, identified by NSN 7H-4310-001020351-PP. The procurement is limited to a single source due to the government's determination that it is uneconomical to acquire the data or rights necessary for competitive bidding, and the contract will be negotiated under FAR 6.302-1. This cartridge is critical for military operations, and the government is not utilizing the policies for the acquisition of commercial items in this solicitation. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of this notice, and they can contact Jaclyn I. Phillips at (717) 605-2984 or via email at Jaclyn.Phillips1@navy.mil for further information.
