Although overshadowed by its predecessor, the B-29, and its successor, the B-36 Peacemaker, the B-50 Superfortress played an extremely important role in the Late 1940s and 1950s within the U.S. Air Force. If the B-29 was a darling in World War II, the B-50 evolved into a much-needed asset in the Cold War era that began just after the former war, with roles significant for nuclear deterrence and reconnaissance missions.
First conceptualized as a B-29 follow-on, the B-50 had heavy-duty Pratt & Whitney R-4360 radial engines with a stronger structure and lighter skin of an aluminum alloy. Among some of the critical improvements, this aircraft was capable of nearly 400 miles per hour at altitudes around 36,700 feet, thus significantly improving performance over that of the B-29. The prototype first flew on 25 June 1947, and the first B-50As entered SAC in June 1948.
The contribution of the B-50 does not end with the tag of being a nuclear bomber. It played a vital role in developing the technology of air-to-air refueling, one of the most important factors for long-range military operations today. In 1949, the B-50A Lucky Lady II was the first to fly around the world without landing, refueled in mid-air by KB-29M tankers. This historic flight of 23,452 miles in 94 hours proved the global reach and strategic abilities of the U.S. Air Force.
The B-50 also flew diverse missions, from weather reconnaissance to electronic espionage. RB-50 variants were equipped for photo-reconnaissance missions; many of these aircraft flew perilous overflights of Soviet and North Korean airspace. Coupled with other sorties in the first decade of the Cold War, much valuable intelligence was gathered. National Weather Service WB-50D “hurricane hunter” aircraft were dispatched to monitor intense weather phenomena and Soviet nuclear tests.
However, the rapid progress in jet technology soon outdated the B-50. As jet-powered bombers such as the B-47 Stratojet and the B-52 Stratofortress entered service, B-50s were phased out. The B-50 never dropped a bomb during combat, though it made immense contributions towards military aviation. It provided a launching platform for future airpower strategies and technologies, especially air-to-air refueling, which remains a cornerstone of U.S. airpower.
Today, only a few B-50s are preserved in museums, with some remaining as a testament to this unsung hero of Cold War aviation. One of those interesting nuggets, reminding people about how quickly technology and strategies came together in the early years of the Cold War, is the legacy of the often-forgotten B-50.
