unless there's been some significant change in Tornado or Typhoons capabilities, surely this faces the same problem that the proposed Buccaneer strike in 1982 had - they can't stay in the air long enough to fly from Assension, fire Storm Shadow ALCM's at MPA, and fly back to Assension.
TLAM's are the only strike option available once MPA is lost/disabled. unless anyone fancies taking Ocean and a deck full of AH-64's down there to fight it out with Skyhawks and Mirage III's...
