Weren't the Tornado F2s simply upgraded to F3s, rather than being scrapped?
It is interesting that the two Eurofighter FCAS partners, Germany and Spain, have opted to retain some upgraded Tranche 1s and/or replace Tranche 1s with the latest Tranche 4/5s, while the two Eurofighter Tempest partners, Italy and the UK, are offloading their Tranche 1s with no replacement. Worth noting that the Italy and the UK also have the F-35, which it seems they see as their bridge through to Tempest.
