Unfortunately, Gerneral Atomics only produce a few of these beasts per (insert you favourite time period... month/year...), and EVERYONE has one or more on order. (US Border patrol HAS two but crashed one - Therefore wants more) - along with the USAF 42nd Attk Sqn (Creech) and US Navy - Mariner.... and RAAF (Maybe?) and Italy et al. If your RAF intends to order up to 7 more, I'm sure you will get them, but in what timeframe??
Will the Waddington spotters ever see one T/O or land on UK soil ????...now that is the question - Or will the punters have to go out to Benbecular to see your UCAVs in action. Does parc-Aberporth have a place to play in this emerging web??
More to the point, will a UK Predator B fire a Hellfire or drop a JDAM. Or did you not get those bits.
