Illustration of space-based lasers destroying targets Light Saber: Space-based lasers would destroy targets by heating them with a powerful beam generated by a chemical reaction between hydrogen and fluorine. However, many such lasers would be required for global coverage; clouds and smoke block the beam; and keeping the beam on target long enough to cause damage is difficult. Illustration: John MacNeill

12 June 2018—The world awakens to an international crisis: officials at the Tokyo airport have detained a foreign airliner suspected of carrying illegal arms. The aggressive and threatening response from the plane’s country of origin, a “rogue” state believed to possess both nuclear and biological weapons, adds credibility to the suspicion. Hamstrung by its rogue status, the country’s economy has been in free fall for decades, and with this latest incident, it’s widely feared that the country will launch a nuclear attack against Japan. U.S. satellites report escalating activity at the country’s rocket-launch facility; other U.S. intelligence indicates that three intermediate-range missiles are being fueled and are within a 15-minute launch window. No air-, sea-, or land-based military system is available to respond in time. The U.S. president demands that the country cease and desist immediately but receives no response. Five minutes later, the U.S. Strategic Command activates a heretofore undisclosed space-based laser; within minutes, it incinerates the launch facility’s command and control center, thus narrowly averting a catastrophe.
