Do SMLs require a Firecon?
The official ruling is that the ship needs to have an operating firecon available during the SML launch phase of the turn (just one irrespective of how many salvoes are fired), but that firecon can then also be used during the main fire phase of the same turn to fire other weapons. This is simply a rule mechanism to avoid having to remember or record which firecons have been used up from phase to phase. A ship that has lost all Firecon capability cannot fire SLMs (or any other weapons).
