content: Following its success as an automobile manufacturer, Rolls-Royce, Ltd. began design and development of aircraft engines at the request of the British Admiralty at the beginning of World War I. The Rolls-Royce Condor was a large and very powerful engine developed at the end of the war in 1918 for use in long-range heavy bombers, principally for bombing Berlin, Germany. Design work was begun at the end of 1917 and retained the same cylinder construction of earlier types. A total of 327 Condors were recorded as having been built.
