Re: Stealing our watches to tell us the time ?
The benefit is that the UK builds a certain percentage of each airframe built.
Personally, I think that:-
1) We ought to buy more F35's to increase our workshare of each jet built, as we are going to get much more back money from the industrial participation of building the aircraft than the financial cost of the aircraft.
2) the F35 is a military disastrous abomination resulting from compromises to get three separate roles into nominally one airframe which compromises it's ability to perform any one of those roles. We'd be better putting each through a car crusher on delivery rather than putting in service and then use the money gained from the industrial participation to buy something designed for the job.
Apart from the fact that going with option 2 would reduce the number of F35's people would buy, and therefore the net gain to UK industry.
So.... The F35 is a wonderful aircraft that your military can't do without! Just buy more of these instead of any other aircraft!
