Pretty feeble compared with Phalanx
Phalanx delivers 4,500 rounds per minutes, each round a tungsten penetrator with a mass of about 100g, at a muzzle velocity of 1,100 m/s. That's an energy of 60kJ per round, and a total potential power delivered to the target of over 4.5MW. It doesn't worry about fog, smoke, or what type of camouflage the target is adorned with, either. For all their potential, current laser systems look pretty feeble next to old-fashioned cannon-based weapons.
