Kitbag,
There were short term Tornado spares shortages as a direct result of the AY Tornado contracts, but at the same time, the injection of capital and commercial pressure allowed a number of lingering difficulties to be addressed that would otherwise have dragged on for years.
The big difference is that Saudi Tornados slowed deliveries when they were needed whereas Saudi Typhoon deliveries promise to delay Typhoons at exactly the time that it is most useful for them to be delayed, and will result in relatively austere Block 8 RAF aircraft (which have the Tranche 2 processors, but hosting Tranche 1 software) being replaced by more useful Block 10s or Block 15s at the back end of Tranche 2.
Industry is already producing Typhoons at a rate which is too fast for the customers to absorb.
