Obviously taken off some Yank forum looking at the wording and the replies which stand out in your head like "Yeah, you wait dude, you Europeans will have your ass kicked" type of thread.
I'm sure there are plenty of upgrades that could be done to the Typhoon but the UK simply won't do it on grounds of cost. You'll probably find later on down the line that the UK Typhoons will be of lower spec than those of our European friends that use the Typhoons of which will probably find the funds to upgrade the Typhoon (engine etc) in a few years time.
