A U.S. Air Force B-52H Stratofortress crashed shortly after takeoff from Edwards Air Force Base, California, on June 15 while conducting a flight test for the aircraft’s radar modernization program, killing all eight personnel on board. The accident marks the first B-52 crash since 2016.
According to the U.S. Air Force, the aircraft was the first B-52H equipped with the new AN/APQ-188 active electronically scanned array (AESA) radar, designed to replace the legacy AN/APQ-166 mechanically scanned radar. It was scheduled to undergo a year-long flight test program. The loss therefore includes not only the aircraft itself but also a critical radar test platform and valuable flight-test data.
The crash comes as the Air Force advances the B-52J modernization program, which includes a new AESA radar, Rolls-Royce F130 engines, upgraded avionics, communications, and weapons interfaces to extend the bomber’s service life into the 2050s. The program has already experienced schedule delays and cost growth, with the radar upgrade triggering congressional review under the Nunn-McCurdy Act. The accident could further delay flight testing, depending on the investigation’s findings and the availability of a replacement test aircraft.
The B-52 modernization effort is proceeding alongside development of the B-21 Raider stealth bomber. While the B-21 is designed to penetrate heavily defended airspace, the upgraded B-52J is expected to remain the Air Force’s primary stand-off strike platform because of its large payload and long endurance.
In the near term, the U.S. Air Force has no ready replacement for the B-52. Although the loss of the radar test aircraft is unlikely to alter the overall modernization program, relying on airframes that entered service more than 60 years ago to meet operational requirements for another three decades carries inherent risks. Despite its durable airframe, large payload, and mature sustainment infrastructure, the B-52 continues to face challenges from airframe aging, supply chain constraints, complex modernization requirements, and limited test resources.
