As the U.S. Air Force moves closer to starting a
major re-engining program for its B-52H Stratofortresses, it is reportedly considering adding in additional upgrades to ensure the bombers will remain combat capable through at least 2050. These updates could include improvements to the iconic plane’s avionics, defensive suite, sensors, ejection systems, and flight data recorder, with the resulting aircraft receiving the new designation B-52J.
