But that's not all! DARPA wants this system, which could go on trucks and ships, to also "address rocket, artillery, mortar, and other conventional threats." There are only a few weapons in the world that can do all of that, and they're mostly lasers. The United States Air Force and Army are developing laser weapons, and the U.S. Navy already fielded one laser weapon, and is working on others. The Marine Corps, which shares a budget with the Navy, is even working on laser-toting anti-drone trucks. And while DARPA will probably want to stick with American companies, both Israel and Germany are showing off anti-drone laser weapons at military trade shows.
