Israel to have partial laser defenses by next year (jpost.com)

I'm truly surprised that lasers appear to be operational defenses against mortars, rockets, and UAVs. I had thought it would be too difficult to get enough energy from a laser to destroy a target.

But if it works, it's really a game-changer for air defense. In particular, each shot will be orders of magnitude cheaper than existing rocket-based defenses. I would think reliability would improve as well, since the laser can continuously track its target, rather than a single shot as with current defenses.

I wonder how effective countermeasures would be. If you put a mirror coating on a missile, will it reflect enough energy to make the laser ineffective?

nope. iirc it depends on specific wavelength of the laser or something. also mirror doesn't reflect 100%

Are the existing defenses rocket based? I thought they were basically a gatling gun


https://en.wikipedia.org/wiki/Iron_Dome

Tamir interceptor missile. $40k-$100k range


Certainly for short range projectiles. See https://en.wikipedia.org/wiki/Iron_Dome


I guess reasonable evolution for arrow system for gen 5 will be literally jewish space lasers


Lasers, technically, cannot have a religion.


You could say they have a coherent belief system.


They can and do - they are strict agnostics.


if they will undergo circumcision, they can


Do they cost more or less after that


more costly to maintain due to extended set of requirements

They have been testing it at a lot at the beginning of the last year. I don’t see it on the official website, wikipedia claims the range to be 7.5km, I heard 10km somewhere earlier. So it’s an addition to Iron Dome, for which range under 10km become challenging. The cost of an intercept is allegedly under $100, which is very impressive. The entire project cost 1B ILS, roughly 260M USD and was done by a government owned company. They already presented a naval version. It’s very impressive.


There are some American companies working on this for counter uas(drone) like blue halo: https://bluehalo.com/product/locust-laser-weapon-system-lws/

They talk about it a lot at trade shows, and I know it’s a big focus for them. Others like Raytheon as well.

No idea if any of them work though.
