The Adour 106 was conceived from a marriage of the US F405, a new digital control and the reheat system taken from the Mk411.
The dry engine exhibited all the promised reliability charactaristics that the USN have experienced over the years with the T45 operation
(there were certainly no issues with the turbine as suggested in a previous thread).
The digital control gave many advantages over previous Mks of Adour, there was no setting up to worry about, and the engine could be tuned around the flight envelope for maximum benefit.
There were issues with the reheat system, but all had an identified fix. Sadly there was not the time or money to embody them.
Given a kinder roll of the dice the 106 Jag could have been an extremely effective tool in today's environment.
