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 and Boeing agreed to a nearly $2.4 billion contract for a new lot of KC-46 aerial tankers on Nov. 21. The deal, announced by the Pentagon, is for 15 new aircraft in Lot 11 at a cost of $2.389 billion—some $159 million per tail.
