Operational history
In March 1948, the service (now the USAF) ordered four more aircraft under the new designation XG-18A and a fifth to be fitted with engines as the YC-122. The air force eventually lost interest in purchasing assault gliders, but continued with the development of the powered variant, purchasing two more examples for evaluation as the YC-122A and redesignating the second of these as the YC-122B when the original Pratt & Whitney engines were swapped for Wright units. This aircraft would form the basis for the definitive service trials version, the YC-122C.
Nine of these aircraft were ordered and although they performed well in evaluation (first at
Following their retirement, the fuselage of one of the YC-122s was used in the construction of the Hiller X-18.
