(Tornado Operational Conversion Unit – TOCU) were tri-nationally mixed. A-Squadron was headed by a German, B-Squadron by a British and C-Squadron by an Italian squadron commander. Standardization Squadron (S-Squadron) was responsible for follow-on training, training of instructor pilots and conducting check flights. Theory lessons and simulator training was conducted by Ground School. Funding Cost sharing followed the ratio of flown sorties: 40:40:20 (Germany/Great Britain/Italy). Closure In the post-Cold War era and the growing differences in the aircraft variants, the three nations decided that they would be better served performing their own type training. There was also a need to find space for British aircraft returning to the UK from Royal Air Force Germany bases, such as RAF Bruggen, that were closing. Consequently, the unit disbanded on 24 February 1999, with Tornado flying ending on 31 March 1999. After TTTE, Cottesmore became the base for Joint Force Harrier. The station housed all the operational Harrier GR9 squadrons in the Royal Air Force, and No. 122 Expeditionary Air Wing. In April 2012 RAF Cottesmore was transferred to the British Army and renamed Kendrew Barracks. Precedent for other training establishments While the Eurofighter project has followed the example of the Tornado programme in many ways, the TTTE model was not adopted. Rather the Eurofighter partners (Germany, Italy, Spain and United Kingdom) have chosen to run national training schemes.
