The U.S. Air Force’s Grandpaps, the B-52 and KC-135, Just Keep On Flying

These planes are older than you: a KC-135 refuels a B-52 in flight.

Over at The Daily Beast, Clive Irving has a neat piece about the venerable U.S. Air Force B-52 Stratofortress and it’s little brother, the KC-135 Stratotanker. The B-52, which turns 65 years old this year, and the KC-135 were both designed by Boeing aeronautical engineers Ed Wells and George Schairer.

Wells and Schairer came up with the basic design for the B-52 over one weekend in 1948, drawing upon advanced concepts developed by Nazi Germany during World War II. The first prototype flew in 1952.

Six days after that first B-52 flight, the two pitched an idea to the Boeing board for a jet-powered passenger aircraft, which they would get the U.S. government pay to develop by marketing it as a military tanker for the B-52. This program would yield the KC-135 and the civilian Boeing 707 airliner. The first KC-135 flew in 1956.

Although seeking replacements, the Air Force is planning on keeping both the B-52 and KC-135 in service past 2050, when both airframes will be over 100 years old. Boeing won a contract to replace the KC-135 in 2011, but its new tanker is woefully late and over budget.

The 76 B-52s have a 70% readiness rate due to their relative simplicity to maintain and the Air Force is about to approve $4 billion in new engines to keep them flying.
