@SASless with the politics in mind, which UK-designed and manufactured turboprop did you have in mind?
It might have been arguable with Shorts(Bombardier..) production of Tucano on-going, but now we are closer to the argument of where exactly UK manufacturing capability for military aircraft is going to be in only a few years. With the end of production of both Hawk and Typhoon looming, Taranis(or a production standard progeny) seemingly nowhere, and no other UK procurement other than F35 apparently on the horizon, is it now time for some home stimulus to support a strategic national capability?
If not, how comfortable are we that the UK will have a fast jet production capability by the time we decide we need a new fast jet, of otherwise that further foreign purchases of Hawk will be forthcoming if we don't eek out the production run a few years?
This is a separate argument to whether BAE Systems need as much capacity as they have, spread across so many sites.
