I think the Tornado will be fully retired by 2020 - something like that
I did see this (Jan 2014) http://theaviationist.com/2014/01/31/dambusters-last-mission-tonka/
Royal Air Force’s 617 Squadron known as the “Dambusters”, from the daring night missions against the Mohne, Eder and Sorpe dams, pivotal to Hitler’s industrial heartland in the Ruhr Valley, back in 1943, completed their last operational mission (over Afghanistan) with the Tornado GR4.
It will be a temporary disbandment though: the unit will reform in 2018, with both Royal Air Force and Navy personnel and it will be equipped with the F-35B Lightning II joint strike fighter.
This last flight was a Close Air Support (CAS) mission, which aimed at helping the coalition troops and was made by Squadron Leader, Mark Jackson.
