Rolls-Royce Power Systems AG

Rolls-Royce Power Systems AG is an industrial technology company that designs, manufactures and services complex power and propulsion solutions for safety-critical applications in the air, at sea and on land. Its technical work spans gas turbine engines, nuclear propulsion, hybrid-electric propulsion, sustainable aviation fuels, small modular reactors and broader decarbonisation technologies. The company reports more than 100 years at the forefront of innovation and operates globally, with a substantial presence in the United Kingdom.

Its portfolio reflects the breadth of those domains. Gas turbine engines are built across the Civil Aerospace and Defence divisions and power what the company describes as the world's most efficient commercial aircraft. Nuclear propulsion systems provide the sole nuclear propulsion for the Royal Navy's submarine fleet. Alongside these, the company develops power systems and sustainable power solutions for land and sea applications, and works on breakthrough propulsion and fuel technologies intended to cut emissions in aviation.

The work sits within commercial aerospace, defence, marine and naval propulsion, energy, global transportation and subsea markets. The engineering culture is described as mission-driven, with an emphasis on safety-critical applications where failure is not an option, and on pioneering technologies that support decarbonisation and a more sustainable future.
