The Boeing C-97 Stratofreighter was a militarized Model 377 optimized for long range heavy cargo transport. The C-97 was based on the B-29 bomber.
Development
The
Boeing C-97 Stratofreighter was developed towards the end of
World War II by fitting an enlarged upper fuselage onto a lower fuselage and wings which were essentially the same as the
B-50 Superfortress with the tail, wing, and engine layout being nearly identical. It was built before the death of Boeing president,
Philip G. JohnsonThe prototype XC-97 was powered by the 2,200 hp (1,640 kW) Wright R-3350 engine, and was fitted with a built-in ramp and a hoist to help in the loading and unloading of supplies and personnel through the large clamshell-type doors in the belly. On January 9, 1945 the first prototype, piloted by Major Curtin L. Reinhardt, flew from Seattle to Washington, DC in 6 hours 4 minutes, an average speed of 383 mph (616 km/h) with 20,000 pounds of cargo, which was for its time rather impressive for such a large aircraft. Production models featured the 3500 hp (2,610 kW) Pratt & Whitney Wasp Major engine, the same engine as the B-50.
The C-97 had a useful payload of 35,000 lb (16 t) and could carry two normal trucks or light tanks. The C-97 was also the first mass produced air transport to feature cabin pressurization, which made long range missions somewhat more comfortable for the crew and passengers.
C-97s evacuated casualties during the Korean War. The USAF Strategic Air Command operated C-97 Stratofreighters from 1949 through 1978. Early in its service life, it served as an airborne alternative SAC command post. While only 60 C-97 transports were built, 812 were built as the KC-97 Stratotanker variant for inflight refueling. The civilian derivative of the C-97 was the Boeing 377 Stratocruiser, a very luxurious transoceanic air liner which featured a lower deck lounge and could be fitted with sleeper cabins.
Two C-97s are still airworthy at the present day, one operated as a privately-owned warbird, the other operated as a fire bomber in the United States.
