The US Air Force obtained 20 CH-53C machines for general transport work, Missile Site support, and aerial drone recovery. The CH-53C was apparently very similar to the HH-53C, even retaining the rescue hoist, the most visible difference being that the CH-53C did not have an inflight refueling probe. Most survivors from 1983 onward were converted to special operations [Pave Low] configuration.
