The Air Force effort to upgrade 112 C-5 airlifters has passed a major hurdle—the successful test of new General Electric engines mounted on one of the airlifters as part of the C-5 Reliability Enhancement and Re-engining Program. There was some concern that the technical risk on this massive overhaul effort would be too great, but everything worked—start up, electronics, thrust reversal, and run up to full power. The engine replacement process included about 70 other modifications and were preceded by the Avionics Modernization Program. Once all AMP and RERP work is complete—around 2020—USAF will change the airlifter designation to C-5M.
The new defense reconciliation bill includes $7.2 billion for Air Force and Navy aviation accounts, almost half of which will buy more F-15EXs. While electronic warfare, drones, connectivity and airlift all get attention, the F-35 was conspicuously absent from the package, with no explanation given.
