Rolls-Royce has wrapped up altitude and operability trials of the F130 engine, advancing the modernization program for the US Air Force’s B-52J Stratofortress. The new engine will succeed the long-serving Pratt & Whitney TF33, which has powered the bomber since the early 1960s. Conducted at the Arnold Engineering Development Complex in Tennessee, the altitude tests confirmed the engine’s ability to sustain performance during prolonged high-altitude strategic missions. Operability evaluations used airflow distortion devices to simulate harsh, real-world conditions and verify stable functioning under stress. In parallel, Integrated Drive Generator testing with Boeing ensured dependable electrical output across varied operational scenarios.
Completion of this testing phase marks the end of the primary engine validation program, with performance data now aligned against computational models. The next stage involves system integration and dual-pod trials at NASA’s Stennis Space Center in Mississippi. After clearing its critical design review in late 2024, the F130 is expected to offer enhanced durability and reduced maintenance requirements, lowering lifecycle costs. Its interchangeable dual-pod setup replaces the current asymmetric configuration, improving logistical efficiency and operational readiness. Once manufacturing begins, engines will be produced and tested at Rolls-Royce’s Indianapolis site, supported by significant long-term investment in US infrastructure.
