What is B-52 Modernization (CERP + Radar Modernization Program)?

The US Air Force's B-52 modernization effort re-engines and re-sensors the B-52H fleet (redesignating it the B-52J) to extend its service life. The Commercial Engine Replacement Program (CERP) replaces the B-52's aging TF33 engines with Rolls-Royce F130 engines, via a $2.04B task order awarded to Boeing in December 2025 (work through May 2033). A parallel Radar Modernization Program (RMP) fits an RTX/Raytheon AN/APQ-188 AESA radar. Flight testing was paused after a June 15, 2026 crash of a B-52H test aircraft killed all 8 crew; the Air Force is modifying a second test aircraft with the upgraded radar and expects to resume testing by the end of 2026, asserting the broader program remains on cost and schedule.
