Sigh...
The Tornado F3 production run of 170 wasn't particularly excessive for the number of squadrons expected to use it - it was only after the downsizing of the RAF in the 1990s that they started ending up in storage in large numbers. As previously mentioned, both the Tornado and Typhoon were/are international collaborations, in which BAe/BAE Warton played a major part in both design and manufacturing, so I'm not sure what point Lewis is trying to make here.
The current plan for the Typhoon is to rotate the surplus planes through the squadrons to prolong the life of the fleet.... but given that the RAF's Tornado GR4 fleet are around 25 years old now with no replacement programme in place, a bit of engineering work to produce a 2-seat strike-optimised Typhoon variant for Tranche 3 might avoid the GR4s having to soldier on for another 25...
...and anyway, isn't the Cold War starting again???
