I've followed the development of the F2000 as good as I could (Wich is quiet hard.)

But I was just wondering, as the F2000 had it's first mission?
And is it being issued anywhere yet??

I believe, as a mission, that it's just a fighter with limited ground attack capabilities. As far as I know, it's staying in the UK.

Do you mean the FN F2000 Rifle, or Eurofighter F2000?

Exactly

The Swiss FN F2000 Rifle.

The know the Eurofigher, it's been used some time now..

I was just wondering about the "new" high-tech "computer" weapon.

The FN F2000 is belgian and i dont believe it has been put in use yet!
The eurofighter is not in service yet with any country yet though it is close to service, there has just recently been a lot of problems with the program due to what weapons it will carry and the amonut of planes to be built.
