The Adour jet engine is the result of a cooperative program between Safran Helicopter Engines and British manufacturer Rolls-Royce, which was established in 1965. The two companies celebrated the Adour's 50th anniversary in June 2015.

Initially developed for the SEPECAT Jaguar twin-engine attack aircraft, which entered service in 1973, more than 3,000 Adour have now been sold in nine different countries. Worldwide, the fleet has totaled more than eight million flight hours.

The Adour is one of the most successful cooperative military engine programs in history.

A total of 13 variants (with and without post-combustion) are used to power light fighter and training aircraft. The most recent versions (Mk. 951, Mk. 971 and F405) power the BAE Systems single engine Hawk Advanced Jet Trainer, and the Boeing/BAE Systems T-45 Goshawk operated by the US Navy. The Adour also powers the BAE Systems Taranis and Dassault Aviation Neuron combat drone technology demonstrators.

The Adour is a dual flow jet engine, capable of providing maximum thrust (with post-combustion) of between 28.9 and 37.4 kN. Its architecture comprises a low-pressure two-stage compressor, a high-pressure five-stage compressor, an annular combustion chamber, a high-pressure single-stage turbine and a low-pressure single-stage turbine. The latest variants are equipped with a dual channel Full Authority Digital Engine Control (FADEC).
