This opportunity involves the repair of C-5 Aft Center Cargo Doors (left and right-hand side “C Model”) for use on the C-5 aircraft until its expected retirement in 2045. The government has full rights to the technical data, and the requirement is open for competitive repair. However, the agency states that only ES3 currently possesses the necessary tooling and can meet urgent delivery needs, making reverse engineering or qualifying a new source uneconomical. No specific budget amount is mentioned. The location for performance of services is not specified.
