Rolls-Royce Holdings plc operates primarily through three main segments: Civil Aerospace, Defence, and Power Systems. The Civil Aerospace division develops and manufactures aero engines for large commercial aircraft, regional jets, and business aviation, alongside comprehensive aftermarket support. The Defence segment supplies military aero engines, naval engines, and submarine nuclear power plants to government and military customers worldwide. The Power Systems division, operating largely under the mtu brand, provides integrated solutions for onsite power generation and propulsion across marine, industrial, and defense markets. Additionally, the company's New Markets segment focuses on developing small modular reactors (SMRs) and new electrical power solutions to support the transition to lower-carbon energy. With a global footprint spanning over 40 countries, Rolls-Royce is a critical supplier to the aerospace and defense industries, distinct from the Rolls-Royce Motor Cars brand which is owned by BMW.
