History Highlight

The KC-97L was a modified version of the earlier KC-97 Stratofreighter, a strategic air refueling tanker derived from the C-97 Stratofreighter cargo aircraft, which was originally modified from World War II-era B-29 Superfortress bombers. What made the "L" model distinct was the addition of two General Electric J47 turbojet engines mounted under the wings, supplementing the aircraft's four massive Pratt & Whitney R-4360 radial piston engines.

This enhancement provided a crucial boost in speed, making the KC-97L more compatible with the jet fighters and bombers it was tasked with refueling.

The KC-97L's service with the Utah Air National Guard came at a time when the Air Force was transitioning to an all-jet tanker fleet. Air National Guard and Air Force Reserve units continued to operate the KC-97s after the active-duty force had begun phasing them out in favor of the newer KC-135 Stratotanker.

In early 1978, the era of the KC-97L came to a close for the Utah Air National Guard as the 191st Air Refueling Squadron began receiving the first of its new KC-135A Stratotankers. This transition to an all-jet tanker marked a significant modernization for the unit, aligning it with the active-duty force's capabilities.

The retiring KC-97Ls were flown to the "boneyard" at Davis-Monthan Air Force Base in Arizona for storage.

The legacy of the KC-97L, however, remains a point of pride for the Utah Air National Guard, representing a unique period in its operational history.
