B52 Stratofortress

Short answer: The Boeing B-52 Stratofortress first flew on April 15, 1952, and entered US Air Force service in 1955. Boeing built 744, and the last B-52H was delivered in 1962.

Only the B-52H model is still flying. The Air Force fact sheet lists a payload of about 70,000 lb of mixed weapons and a 185 ft wingspan, with eight engines in four paired pods. It was built for high-altitude nuclear missions and was later adapted for low-level flight, conventional bombing and cruise missiles. Under the Commercial Engine Replacement Program, the Air Force plans to fit Rolls-Royce F130 engines and a new radar, rename the aircraft the B-52J and keep it in service into the 2050s. On June 15, 2026, a B-52H radar test aircraft crashed on takeoff at Edwards Air Force Base, killing all eight crew members. As of July 2026, the cause was under investigation.

DID YOU KNOW? The Boeing B52 Stratofortress is a long range strategic bomber operated by the United States Air Force, first entering service in 1955 during the Cold War. Designed for high-altitude nuclear deterrence missions, the B52 evolved into one of the most versatile bombers ever built, capable of carrying an enormous payload of conventional bombs, precision guided munitions, and cruise missiles. Its distinctive design features swept wings and eight jet engines mounted in four twin pods under the wings. NOW YOU KNOW!

The write-up

Built in the 1950s, flying into the 2050s. The Air Force plans new engines and radar for the B-52.

  1. Exhibit A

    Origins

    Boeing's design first flew as the YB-52 on April 15, 1952, and the bomber entered service with Strategic Air Command in 1955. Boeing built 744 across eight models, ending with the B-52H in 1962.

  2. Exhibit B

    The airframe

    The B-52 has 35-degree swept wings spanning 185 ft and eight engines (Pratt & Whitney TF33s on the H model) in four paired pods. The Air Force fact sheet lists about 70,000 lb of mixed ordnance.

  3. Exhibit C

    Changing roles

    It was built for high-altitude nuclear bombing. Over time it was adapted for low-level penetration, conventional carpet bombing and standoff cruise missiles, and later for precision-guided weapons.

  4. Exhibit D

    Toward the B-52J

    The Air Force plans to replace the TF33s with Rolls-Royce F130 engines under the Commercial Engine Replacement Program, and to add an AN/APQ-188 radar. Upgraded aircraft will be called B-52Js and are meant to fly into the 2050s. GAO has warned the program is behind schedule.

  5. Exhibit E

    The 2026 crash

    On June 15, 2026, a B-52H fitted for radar testing crashed on takeoff at Edwards Air Force Base, California, and all eight crew members were killed. The Air Force said a second test aircraft was being modified so testing could resume.
