#ThrowbackThursday
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 were 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 occurred as the Air Force transitioned 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 KC-97L era came to a close for the Utah Air National Guard, as the 191st Air Refueling Squadron began receiving its first KC-135A Stratotanker. This transition to an all-jet tanker marked a significant modernization for the unit, aligning it with the active-duty force's capabilities.
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.
