I don't think it has been announced publicly yet. There is a bit of a fight going on it would appear. Tonka got a lot of development over her 40 years and the Typhoon has not yet got the same capability despite an impressive sprint by BAE to add additional capability. With the F35 not due to be in operational service with the RAF until 2020 we have a bit of a gap. I suspect they will be locked in a hanger for a bit. The initial F35's are due to be put on the new carrier I think.
There will be three Tornado final flights shortly. I believe one will include Boscombe which I may pop along for. Tonka was held in high regard.
