V-22's are compatible with KC-10 and KC-46, refueling happens at around 200ktsI don't think the USAF has any KC-130s. I'm 99.999% sure it's all -135s and KC-10s.
So, good luck to the Army getting support from the VMGRs. They're already tapped out.
And I'm not sure if the KC-10 or KC-135 can get slow enough to refuel helos.
First in-air refueling between KC-46, AFSOC CV-22
The 20th Special Operations Squadron and 349th Air Refueling Squadron brought a CV-22 Osprey and KC-46 Pegasus together for in-air refueling training over Cannon AFB early June.
