The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure five units of a refueling coupling, identified by NSN 7R-1680-013126219-FZ and part number 61520-2, from Eaton Corp, the sole source manufacturer. This procurement is critical as the coupling is a miscellaneous aircraft accessory essential for operational readiness, and no alternative sources are approved due to the lack of available drawings or data. Interested parties must submit their capability statements to the primary contact, Christophe M. Kilcourse, via email at Christopher.kilcours@navy.mil within 15 days of this notice, with the anticipated award date set for January 2025.
