"Why were the FA.2s retired so early? "
Politics and bolony, my dear boy.
The British, bless us, have a history of having designing and making something really good, world beating, in many different fields.
Yet those who ought to know better would flitter all this away for nothing. Well, usually it's for monetary reasons.
Am I bitter, you bet I am.
The FA.2 is a case in point. Excellent radar, well armed for BVR (AMRAAM), superb at dogfighting and capable of shooting down sea-skimming missiles. Just what you need for Fleet defence.
The decision to withdraw the FA.2 was taken back in 2002 and they disppeared in 2006.
Let's just hope that we don't suffer another "rethink" with the F-35.
