Watch Navy's New Laser Cannon, Mounted on a Ship, Kill a Drone

How does it do against maneuvering targets? The classic sci-fi defense would be to start turning. This wouldn't be so much to avoid the beam as it would be to distribute the energy of the beam across the hull. Also, the drone could produce an aerosolized "smokescreen" whose particles are sized to disperse most of the laser's energy. Such a system could adjust to many different frequencies, making the drone harder to kill. By attacking in a swarm and using such tactics, one could swamp the laser's ability to down the drones.

That's a fake. Real laser weapons like seen in Star Wars and The Terminator can be seen coming out of the gun at very fast speeds of hundreds of miles an hour. Also, a blaster like Han Solo had would have blow up that drone as soon as the red laser blast hit it.
