I don't follow Draken? The Typhoon is still the primary interceptor, if the R.A.F.are looking to get rid of the GR4, they'll need to line up a replacement! No? This has got nothing to do with trying to prop up the Typhoon. If they could, they'd leave the Typhoon as an nterceptor and look for a replacement for the GR4s. Bearing in mind the cost involved and the fact that the Typhoon is, as you say at the start of its career in mud moving (rather than at its best ever) and is still needed for its primary purpose of shooting down stuff, which would you rather do? Disband the Typhoons and bring the Harrier GR9 back, which can do ground attack nearly as well as the Typhoon can do Air Superiority, and Air Superiority nearly as well as the C130!
