(Popular Mechanics) The laser jammer by ITT that uses a trick of quantum mechanics to create a powerful laser that can target missiles approaching from any direction.
Common Infrared Countermeasures (CIRCM) system uses a laser to scramble the seekers used by missiles that have infrared homing devices in their tips. The US Navy and Army want these defenses for their helicopters, which are particularly vulnerable to heat-seeking missiles. The idea of using lasers to scramble IR-guided missiles has been around for a while, and most of the large defense firms have created systems to do so. But they’ve been waiting for the Pentagon to place an order to replace the current laser jammer, BAE’s Advanced Threat Infrared Countermeasure (ATIRCM). Now it has, and the competition is under way.
