Rolls-Royce and the UK government have agreed a planned 10-year, £2.5 billion research and technology programme for more efficient, lower-emission gas-turbine engines for civil and defence aerospace. The initiative is intended to return Rolls-Royce to the next generation of single-aisle aircraft, with work centred in the UK and an engine demonstrator aimed at securing a position on future narrowbody programmes.
The aircraft are expected to enter commercial service in the mid-to-late 2030s, with manufacturers likely to select engine partners over the next several years. Rolls-Royce is seeking to apply its UltraFan technology in a market dominated by established suppliers including GE Aerospace and Pratt & Whitney.
The initial programme is expected to support 3,300 jobs by the end of 2029 and sustain UK capabilities in engineering, testing and manufacturing. If Rolls-Royce secures an engine position, the company estimates that the programme could eventually create tens of thousands of jobs across its UK operations and supply chain and contribute up to £120 billion to the UK economy over its lifetime.
The agreement provides a framework for future cooperation rather than a final engine production contract or confirmed aircraft selection. No new grants have been awarded at this stage, and any government support remains subject to legal, value-for-money, affordability and approval procedures.
