Jacko,
Generic answer that the cynic is probably looking for is "Yes".
But the more interesting question is what the opposition is, and how that plays out - ie, if you're going to deploy a battle group to Trashcanistan to do peace support operations, then the FJ requirement is rather different that if you're going to take on the Berzerkistani's 3 Guards Tank Army with organic SA-15/SA-17/SA-20/SA-12 and a shedload of Su-30MKs with PL-12.
So the better answer is that it is "threat dependent".
