Rolls-Royce is a Power Systems company: for more than a hundred years we have been providing power for aircraft, ships and land applications. Our vision is to provide “better power for a changing world”. Better, because our customers need our systems to become more efficient all the time as we respond to the growing demand for all types of power in our fast changing world. We are best known for our aero engines, that power many of the world’s most advanced passenger jets, like the new Airbus A350 and the Boeing 787 Dreamliner. But, there is much more to the company than that. We also produce low–emission power systems for ships, some of which we design ourselves. We power a wide array of land vehicles: ranging from trains to combine harvesters, and build engines that can generate electricity. Around half of our revenues come from servicing the power systems we deliver.
