• 1914 The company's first aero engine was the Eagle. Around half the aircraft engines used by the Allies in World War I were made by Rolls-Royce. By the late 1920s, aero engines made up most of Rolls-Royce's business.

• 1933 The Condor engine was produced.

• 1935 Henry Royce's last design was the Merlin aero engine, which came out in 1935, although he had died in 1933. This was developed after the R engine, which had powered a record-breaking Supermarine S6B seaplane to almost 400 mph in the 1931 Schneider Trophy. The Merlin was a powerful V12 engine and was fitted into many World War II aircraft: the Hawker Hurricane, Supermarine Spitfire, de Havilland Mosquito (two-engine), Avro Lancaster (four-engine), Vickers Wellington (two-engine); it also transformed the American P-51 Mustang into possibly the best fighter of its time, its Merlin engine built by Packard under licence. Over 160,000 Merlin engines were produced. The Merlin crossed over into military vehicle use as the Meteor powering the Centurion tank among others.

• 1937 Aero engine manufacturers. "Kestrel" Aero Engines. "Merlin" Aero Engines.

• In the post-World War II period Rolls-Royce made significant advances in gas turbine engine design and manufacture. The Dart and Tyne turboprop engines were particularly important, enabling airlines to cut times for shorter journeys whilst jet airliners were introduced on longer services. The Dart engine was used in Argosy, Avro 748, Friendship, Herald and Viscount aircraft, whilst the more powerful Tyne powered the Atlantic, Transall and Vanguard, and the SRN-4 hovercraft. Many of these turboprops are still in service. Amongst the jet engines of this period was the RB163 Spey, which powers the Trident, BAC 1-11, Grumman Gulfstream II and Fokker F28.

• During the late 1950s and 1960s there was a significant rationalisation of all aspects of British aerospace and this included aero-engine manufacturers, culminating in the merger of Rolls-Royce and Bristol Siddeley in 1966 (Bristol Siddeley had itself resulted from the merger of Armstrong Siddeley and Bristol Aero Engines in 1959). Bristol Siddeley, with its principal factory at Filton, near Bristol, had a strong base in military engines, including the Olympus, Viper, Pegasus and Orpheus. They also manufactured the Olympus 593 Mk610 for Concorde.

• 1968 First test run of the RB.211 turbo-fan engine for Lockheed.
