Founded in the early 20th century, it began as a pioneer in aero
engine design and has grown into a global engineering powerhouse.
It develops and produces engines and power systems for commercial and military aircraft, naval vessels, submarines, and energy infrastructure.
Headquartered in London, it operates across four core segments—civil aerospace, defence, power systems and emerging markets like nuclear and modular reactors.
It supports iconic programmes—supplying wide
