The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure 22 units of a detection unit, identified by NSN 7H-6665-123891629, for repair or modification purposes. This procurement is intended to negotiate with a single source, as the government has determined it uneconomical to acquire the necessary data or rights to purchase or contract the repair from additional sources. The detection units are critical for hazard detection applications, and the government is not utilizing the policies in FAR Part 12 for this solicitation. Interested parties must submit their interest and capability to the primary contact, Joshua Eshleman, at joshua.j.eshleman@navy.mil, prior to the award date, and should include their CAGE code in all solicitation requests.
