I have to throw another vote in for launch transits. This is a really frustrating piece of the game mechanic for me.
I had a Kilo not 5nm off my starboard that was launching Starfish, after Starfish, after Starfish at me and I was none the wiser where the torps were coming from. Everytime I evaded a torp another one would drop outta the air. I assumed that it was a Helo or P3, but after finally getting blown outta the water and replaying the mission it turned out to be a Kilo not 5nm from me

.
Come on..... this just isn't right, missile launches need a transient consquences.
