Rolls-Royce and the UK Government have announced plans for a joint £2.5 billion, ten-year research and technology programme to advance jet engine technologies for civil and defence aerospace.
Subject to final agreement, the programme would support more efficient, lower-emission propulsion, strengthen advanced manufacturing and sustain critical engineering and testing capabilities. A central ambition is to secure a Rolls-Royce engine position, in partnership, on the next generation of narrowbody aircraft, expected to enter service in the mid-to-late 2030s.
For context, UltraFan is a scalable suite of technologies, being developed through demonstrators for both single-aisle and widebody aircraft. These combine advances in engine design, lightweight composite fans, power gearboxes and combustion systems to improve efficiency.
- The UltraFan 30 narrowbody demonstrator, planned for ground testing in 2028, targets a 20% fuel-burn improvement relative to current in-service engines.
- The UltraFan 80 widebody demonstrator (the world’s largest aero-demonstrator), first tested in 2023, targets a 25% fuel-efficiency improvement over first-generation Trent engines, or 10% over the Trent XWB.
The defence significance lies in the wider programme’s investment in gas turbine technology, specialist skills, and development infrastructure that underpin military propulsion capability. UltraFan’s narrowbody and widebody demonstrators address commercial aviation and support the broader technology base required for future defence engines.
For African aviation, the longer-term relevance is the development of more efficient propulsion across the aircraft sizes needed for regional connectivity and long-haul growth.
