The award exercises the one-year base period under the service branchâs indefinite-delivery/indefinite-quantity contract, the Defense Department said Monday.
E-4B works as a command-and-control post that serves the U.S. president, defense secretary and the Joint Chiefs of Staff during national emergencies.
The aircraft is a military version of Boeing 747-200 and has a satellite communications system, four General Electric-built CF6-50E2 turbofan engines and a technical control facility.
Work will occur in San Antonio and Oklahoma City through Dec. 30, 2016, and includes supply chain management, aircraft depot and engine maintenance, program management and field service staff support.
The Air Force Life Cycle Management Center will obligate $13.6 million from fiscal 2016 operations and maintenance funds at the time of award, according to DoD.
