The B-52H is a long-range nuclear/conventional bomber and USAF’s primary standoff cruise missile carrier. The YB-52 prototype first flew on April 15, 1952, and Strategic Air Command declared IOC with the B-52A on June 19, 1955. Boeing produced a total of 744 B-52s culminating in the current B-52H. Multimission capabilities include long-range precision strike, CAS, air interdiction, defense suppression, and maritime surveillance utilizing both Litening and Sniper targeting pods.
The B-52 is undergoing major upgrades to replace key obsolescent systems including engines, radar, comms, and weapons interface to extend the fleet through the 2050s. Combat Network Communications Technology (CONECT) recently replaced cockpit displays and comms and added integrated mission-management, including Link 16, and machine-to-machine tasking/retargeting. It forms the digital backbone of the Internal Weapons Bay Upgrade transitioning the Conventional Rotary Launchers designed for CALCM to carry the modern AGM-158B JASSM-ER. This nearly doubles the B-52’s JASSM, JDAM, and MALD payloads and reduces drag for longer range. CONECT also enables associated mods including Tactical Data Link to add low-latency, jam-resistant C2/comms as well as GPS updates.
USAF is pursuing the Radar Modernization Program to replace the B-52’s legacy radar with an AESA radar and Commercial Engine Replacement Program (CERP) to reengine the fleet. CERP will replace the B-52’s current engines with efficient and reliable Rolls-Royce F130-200 turbofans in a modified pylon-mounted eight-engine arrangement. Reengined aircraft will be redesignated B-52J and fleetwide retrofits are expected to be completed by 2038. The B-52J’s IOC has slipped three years to 2033 due to the cost and complexity of integrating new engines and radar.
The radar entered flighttesting last December but USAF was also forced to postpone retrofitting the B-52J with AESA-tailored radomes after a critical cost spike triggered by congressional notification and program re-scope in 2025. An initial two B-52s will be retrofit with Rolls-Royce engines for flight-testing as Boeing works to correct engine nacelles airflow issues. Current upgrades include MIDS/ JTRS higher capacity, jam-resistant Link 16, Mobile User Objective System (MUOS) secure, jam-resistant SATCOM and NATO-interoperable SATURN UHF, and VLF/LF receiver modernization. Future upgrades include color targeting pod displays to enhance performance and situational awareness, and AEHF SATCOM installation. Ongoing Long-Range Standoff (LRSO) cruise missile flight-testing will cement the B-52’s nuclear role, complementing the B-21 Raider, potentially through the 2050s.
