Yes and No.
Each fire control will determine what the nearest salvo is... at firing time. So if FC1 takes out salvo1, FC2 will look for the next salvo and not be stuck trying to engage the now eliminated salvo1.
Maybe i understand
Example:
Salvo 0001 4x size 4 missile (distance 1m km)
Salvo 0002 4x size 4 missile (distance 2m km)
Anti-M equipment: 3 Quad Laser Turrett (3 FC all in area defence mode)
--- 5 second (events)
- first FC target Salvo 0001 and fire
- 1 missed, 3 hit
- second FC target Salvo 0001 and fire
- 1 missed, 3 hit (2 overkill)
- third FC target Salvo 0002 (because Salvoo 0001 no longer exists)
- 2 missed, 2 hit
--- ecc...
All correct?
