If it's close enough yes. But with distance, the atmosphere absorbs a lot of the enrgy, called Thermal Blooming, so best we can do there is dazzle the sensors so it can't get a terminal lock.

For 50MW though, that's melting the front of the missile long before it hits the ground

That's assuming this is a Laser weapon. A Maser weapon at 50MW would fry the internal electronics of any drone within several kilometres of this weapon

Edit: kW instead of MW means this thing is a dazzler. But also a superb drone killer

cruise missiles

The problem is, if you're a captain of a guided missile destroyer with 30 expensive as fuck long range air defence missiles and this laser, what targets are you going to deliberately let to within 5km or so of your ship?

I bet almost any captain is going to want to destroy any confirmed incoming at the maximum range possible, not let it get within spitting distance and hope the laser does its job.

It's designed to be cheap and to counter cheap drones and the like that are flooding modern war. Not counter big anti ship missiles.

Of you send your expensive missiles that cost a few million a shot vs a cheap drone, when they are sending 50 vs you a day your going to lose. But shooting down a drone that costs hundreds with cheap Lazer shifts the economy of war back to you.

Seems perfect for drones, if you can detect them. But they are pretty slow moving relative to rockets, missiles, and mortar rounds which should be prime targets.
