Fighter intercept of salvo missiles

Hello

Came up against this one at the weekend.

I fired a salvo at an enemy ship which finished it's move within 
3" of the salvo. 
My opponent had a fighter sqaudron within 6" of the salvo 
marker. They were not screening the target ship.

Now the problem I had was that the fighters went first which 
ment we had not rolled to see how many missiles were on target.
The thing which was not clear is that I argued that the fighters 
were engaging all 6 missiles from the salvo since the rules say 
that you roll to see how many are on target. In this case the 
target was not the fighters.
As it was I rolled to see how many were on target. 3 these were 
wiped out by the fighters.
Doing it this way would suggest that when I fired the salvo 3 of 
the 6 missiles flew of at weird angles when launched.
This hardly seems fair.

What do you lot think?
