Star Wars: U.S. Navy to answer hypersonic anti-ship missile threat with lasers

May 4, 2012 – HIGH TECH - Northrop Grumman Corporation has test fired the first product in its next-generation FIRESTRIKE family of high-energy, solid-state lasers that meet goals for size and weight reduction and ruggedization for operational applications. The lethality testing used a single Gamma chain at short distance in a way that simulated the effects that a laser weapon of several chains aboard a Navy ship could achieve at a range of several miles. “We validated that the laser could produce the amount of energy we predicted, and that the energy would have the effect on the target that we predicted,” said Wildt. “Gamma has equaled or exceeded the performance we achieved in previous slab lasers, but the real advancement here is in packaging and ruggedization for operations in real-world military platforms,” he added. The term “slab laser” refers to a class of high-power, solid-state lasers with a gain medium, or source of atoms that emit light, in the form of a slab about the size of a microscope slide. The components used in the test included the skin of a surplus BQM-74 drone and other parts configured to represent critical internal components. The BQM-74 was formerly produced by Northrop Grumman for the Navy as a representative cruise missile threat and used for testing defensive systems. “The FIRESTRIKE laser, announced in 2008, forms the backbone near-term laser weapon systems from Northrop Grumman. Combined with advanced electro optical and/or infrared sensors, FIRESTRIKE™ line replaceable units and their subsystems can provide military services with active defense, offensive precision strike and enhanced situational awareness capabilities, all in the same weapon system,” Wildt said. –Physics
