Significance of Type: The KC-97 closely resembles the B-29 bomber, the aircraft on which it was based. The KC-97 has the same wing, tail and engines as the B-29, but has a whale-like “double-bubble” fuselage.

Outfitted with a flying boom and loaded with fuel, the four engine, propeller driven aircraft could fly fast enough to match the minimum speed of a B-47 bomber. As the pioneer aircraft for aerial refueling, the 2nd Air Refueling Squadron at Hunter AFB, GA set a record by transferring 563,270 gallons of fuel to B-47′s in sixteen days in 1955.

About our KC-97G: This KC-97G was manufactured by Boeing in Seattle, Washington and delivered to the USAF on April 3, 1955. It was dropped from the inventory and delivered to the Strategic Air & Space Museum in September, 1964.
