On Dec. 12, 2023, a C-5M Super Galaxy and a KC-10 Extender conducted a reverse flow air refueling training over Northern California and Oregon, as part of a PoC (Proof of Concept) designed to maintain readiness in emergency situations to prevent loss of a tanker aircraft.

The C-5M offloaded 23,500 pounds of fuel in approximately thirty minutes to the KC-10 during the test. Noteworthy, reverse air refueling is something that both KC-10s and KC-135s have been able to perform for decades. However this was the first time the test assessed the ability to siphon fuel back in to the tanker from the Super Galaxy.
