It'd open up entirely new mission tactics. The new frigates can skimp on speed, armour and anti-fighter defences, but will have huge offensive capacity. Park them outside of beam range in the mission field - what would that be, 30km or something? And have something like Pegasus fighters flying about tagging targets (just like the TAG system, except that's for beam cannons) for SSM. Once you've got sufficient target data, the frigates launch their barrage against the enemy. (We probably ought to make the 'sufficient' data something like 120 seconds worth of targeting laser. That sounds like a lot, but it can't be too easy - otherwise the power of SSM won't be balanced. And you could spread it out between a wing of fighters - 30 seconds each from 4 fighters, something like that.) Gee, the possibilities...
