When the sensor gets a good track on you, then the FC system has you
locked in and it is almost impossible to break it off.

Not firing ship, scanning ship. A ship with one FC may only fire at
one ship at a time but may have mutliple tracks simultaneously.

These are all potential event to do that. Most ECM today is not to
break a ship's tracking methods but to spoof a self seeking missile to
either track the wrong target (before lock on has occured) or make it
think
that the new bloom is the original target.

I would leave the two applications seperate. Space has a much
larger
volume than what we deal with today and the requirement to purchase the
two
different systems represents the costs and mass involved to make the
trade
off between time to detection and the number of targets I can fire at in
one turn.
