Actually what im seeing from other countries are even larger and heavier technologies. I mean all of these can be mobilized as low speed ground vehicles, a far cry from the mobility and invasive potential of aircraft. Its the energy requirement thats the kicker, and the weight of batteries. Which is why we’re only seeing this technology being deployed as stationary anti air defense. Its a nice bonus that lasers have to travel in a straight line so we dont have to worry about long range trajectory attacks like with ICBM’s.
The only downside im seeing so far is surprisingly limited range hampering its ability to handle incoming supersonic targets.
