I see your point but the problem is probably a lot more cash just for the speed. Plenty of other weapons/sensors can be integrated on Reaper (sorry), if they aren't already, you just need to pay. And speed isn't an issue in the current theatre - you can pretty much guarantee that a Reaper will be on task long before Tornado (or Typhoon

), simply because it is already there. Persistence has a quality all of its own!
There are exceptions, of course, and plenty of other theatres but are they worth the RISK and cost? IMHO going down an anglo-french route when we already have such a capable platform would have been madness (or politics, which amounts to the same thing).
