[edit] History
The Adour was a turbofan engine developed primarily to power the Anglo-French SEPECAT Jaguars Fighter-bombers, achieving its first successful test run in 1968. It comes with or without the installation of an afterburner (reheat).
To date, more than 2,800 Adours have been produced, for 19 different armed forces with total flying hours logged at over 7 million. The U.S. military designation for this engine is the F405-RR-401 (a derivative of the Adour Mk 871), which is currently used to power the fleet of Boeing / BAE Systems T-45 Goshawk trainer jets of the US Navy.
[edit] Variants
Reheated

- Adour Mk 104
- Adour Mk 106 - Replacement for the Jaguar's Mk104 engine (developed from the Adour 871) with a reheat section. The RAF refitted its fleet with this engine as part of the GR3 upgrade.[1] In May 2007, following the retirement of the last 16 Jaguars from No. 6 Squadron RAF, based at RAF Coningsby, the Adour 106 has been phased out of RAF service.[2]
- Adour Mk 804
- Adour Mk 811

- Adour Mk 861
- Adour Mk 871
- Adour Mk 951 - Designed for the latest versions of the BAE Hawk, with improved performance on the 871, with up to twice the service life. The Adour 951 is a more fundamental redesign than the Adour Mk106, featuring an all-new fan and combustor and revised HP and LP turbines.
