Rolls-Royce traces its roots back to 1884 when Henry Royce established an electrical and mechanical company. In 1904, Royce began manufacturing cars and later collaborated with CS Rolls & Co., owned by Charles Rolls, to sell the cars. With the onset of the First World War, Rolls-Royce began its first foray into aircraft engine manufacturing. The engine manufacturing section of Rolls-Royce produces propulsion systems for marine equipment as well as power generation systems. Overall, Rolls-Royce operates in the industrials sector under four segments. Civil aerospace entails manufacture of engines for civilian aircrafts and power systems that focus on power generation systems and marine propulsion systems. The defense segment entails manufacturing of engines for military aircraft, and ITP Aero, which entails manufacture of gas turbines, meant for the oil and gas industry.
