All Hail.
In recent test-blasts, Pentagon-researchers at Northrop Grumman managed to get its 105 kilowatts of power out of their laser -- past the "100kW threshold [that] has been viewed traditionally as a proof of principle for 'weapons grade' power levels for high-energy lasers," Northrop's vice president of directed energy systems, Dan Wildt, said in a statement.
Does that mean energy weapons are a done deal? Hardly. There are still all sorts of technical issues -- thermal management and miniaturization, to name two -- that have to be handled first. Then, the ray gunners have to find the money. The National Academies figure it'll take another $100 million to get battlefield lasers right.
Still, clearing the 100 kilowatt hurdle is a big deal. For the longest time, the military research community concentrated on developing chemical-powered lasers. The ray guns produced massively powerful laser blasts. But the noxious stuff needed to produce all that power makes the weapons all-but-impractical in a war zone. (One ray gun took as many as eight shipping containers' worth of chemicals and electronics to power a single blaster.) So the Defense Department shifted gears, and poured money into electric lasers. They're much less hassle to operate. And, given a steady supply of power, they should be able to fire away, almost indefinitely.
Indefinite fire rate means you won't have to burn the barrel or stop for empties?? Burn through ballistic armor with one shot? No stun setting? SWEET.
