We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

The UK has successfully fired a high-power laser weapon against an aerial target for the first time in a trial.

It is hoped that the test will pave the way for a low-cost alternative to missiles to shoot down targets like drones.

The DragonFire weapon is precise enough to hit a £1 coin from a kilometre away, the Ministry of Defence (MoD) says.

The cheapest option is a CWIZ but even that thing costs something like $40,000 a minute to fire

You don't have to spam stupid amounts of individual bullets.

You don't have to spam a stupid amount of individual bullets.

You would against a drone swarm, especially if each drone is more than a meter or two away from the next one.

I will say that my memory was bad and so my cost was wrong. A CWIZ has a rate of fire of about 3,000 rounds a minute with each round costing something like $30. So the firing cost per minute is $90,000!

Back to your point; engaging a single target will use about 100 rounds for a cost of $3,000. So if for a modest swarm of 10 drones dispersed such that each has to be targeted individually the total cost would be around $30,000. Contrast that with a HEL system where the total cost would be around $50.

Even if you could upgrade the CWIZ to "one shot one kill" levels of accuracy it would still cost $30 per drone so our little swarm would cost $300 to deal with.

I love the CWIZ but the economics are entirely in favor of HEL systems.
