Raytheon Wins $603M Contract for B-52H Radar Modernization

This is a developing story. Information may change as official details are released.

Raytheon has secured a $603,000,000 sole-source contract from the U.S. Air Force (USAF) to produce and sustain the new AN/APQ-188 radar for the Boeing B-52H Stratofortress fleet, advancing a critical modernization effort despite the recent loss of the program’s primary test aircraft.

The U.S. Department of Defense announced the indefinite-delivery/indefinite-quantity (IDIQ) contract on August 25, 2026, following the official award on August 21, 2026. The agreement establishes the ceiling value for the production phase of the B-52 Radar Modernization Program (RMP). The Air Force Life Cycle Management Center (AFLCMC) at Wright-Patterson Air Force Base (FFO) in Ohio is the contracting activity, obligating $46,008,396 in fiscal 2026 aircraft procurement funds with the initial delivery order.

Upgrading the B-52 radar capabilities

The RMP replaces the bomber’s 1960s-era mechanically scanned AN/APQ-166 radar with the Raytheon AN/APQ-188, an Active Electronically Scanned Array (AESA) system. The new Radar-Systems is a derivative of the AN/APG-79 used on the F/A-18 and forms a cornerstone of the broader B-52J upgrade package designed to keep the fleet operational into the 2050s.

According to the Department of Defense, Raytheon will perform the contract work across multiple facilities, including Forrest, Mississippi; El Segundo, California; McKinney, Texas; and Warner Robins, Georgia. The contract is expected to be completed by August 20, 2031.

Program continuity following testbed loss

The production contract award follows a major setback for the RMP during the flight testing phase. On June 15, 2026, the sole B-52 radar testbed aircraft crashed shortly after takeoff at Edwards Air Force Base (EDW) in California. The USAF confirmed the accident resulted in the deaths of all eight crew members on board, which included military personnel, government civilians, and contractors. The official cause of the accident remains under Investigation by the USAF.

Despite the loss of the initial testbed, military officials have confirmed the modernization program will proceed. According to reporting by DefenseScoop, Col. Spencer Turner, the B-52 System Program Manager, stated that the original acquisition strategy always included two test aircraft.

Turner confirmed that work on the second aircraft is actively underway at The Boeing Company facility in San Antonio, Texas. He noted that the service expects to “complete the full modification and put the full radar suite onto the aircraft this year and proceed with testing.” Following the June 15, 2026 accident, the active USAF fleet stands at 75 B-52H bombers.

AirPro News analysis

The decision to award a $603,000,000 production contract just two months after the loss of the primary testbed underscores the firm commitment of the USAF to the B-52J upgrade timeline. Because the AN/APQ-188 is heavily derived from an existing, mature AESA system, the service likely views the radar technology itself as low-risk, separating the radar’s production readiness from the ongoing investigation into the June 15 accident. We note that delaying the production contract until a second testbed completes flight trials would have likely pushed the B-52J initial operational capability timeline to the right, a delay the USAF appears unwilling to accept as it plans to operate the airframe for another three decades.
