This short video is about anti-missile laser weapons developed by the Israelis and similar by the USA

The Israeli Iron Dome system individual rounds cost $80,000 each, at least 500 times the cost of each of the 10,000 rockets which have been fired from Gaza into Israel, while the cost of each laser shot is about $3.50, or as the commentator puts it, a loaf of bread.

The laser beam of course travels at the speed of light, so can intercept any target at any speed on which it can trained.

It is worth pointing out that the laser is a defensive weapon, used to bring down weapons of offence.

I'm posting this to show the amazing development of what you might call a science fiction phasor weapon. I'm all for peace, wishing such did not need to be deployed.
