The United Kingdom is building a laser gun. Technically, the Ministry of Defence is looking for a contractor to build a "laser directed energy weapon capability demonstrator," but that's a jargony soup for laser gun. There will be a briefing for defense companies in mid-April, where the Ministry of Defence can hammer out all the business matters that go into buying a weapon that destroys things with light.
It's not a new dream. Declassified memos from 1983 revealed that Great Britain had by then already decades of work on laser weaponry, including one designed to dazzle low-flying pilots during the Falklands War.
