According to the just-released Directorate of Operational Test & Evaluation annual report, the restructured C-5 Reliability Enhancement and Re-engining Program requires “further assessment” before the Pentagon can formally determine just how much the C-5M (a combination of the RERP and the Avionics Modernization Program) makeover will increase capability for the behemoth airlifter. Flight testing done last summer showed a 20 percent increase in fuel efficiency and greater reliability. The Air Force decided last year to convert only B and C model C-5s to C-5M Super Galaxy status, leaving the oldest C-5s, the A Models, to receive only the AMP upgrade. The service planned to put the first three production RERP aircraft in the field (see above) for crew familiarization and, sometime this summer, to provide three systems development and demonstration aircraft reconfigured for IOT&E testing, which it must complete to support a full-rate production decision. According to the DOT&E annual report, the C-5 enterprise needs to address “remaining deficiencies” identified during the avionics modernization program testing by ensuring technical orders are validated and verified before RERP begins its IOT&E phase.
The Air Force has finished modifying and testing the new VC-25B Bridge aircraft that will serve as a temporary Air Force One, the service announced May 1. All that’s left now is to finish painting the jet before it starts flying this summer.
