More has emerged on the US Air Force Research Laboratory's Electric Laser on Large Aircraft (ELLA) program and, as anticipated, it's an effort to fit DARPA's Hellads laser into the weapons bay of a B-1B bomber to flight-test a high-power electric laser against tactical targets. General Atomics and Textron Systems are developing rival 150kW lasers under Hellads, with the goal of demonstrating a laser weapon system weighing less than 5kg/kW - substantially smaller and lighter than any previous airborne laser. Lockheed Martin is designing the laser weapon system module (LWSM), including power, cooling and beam director. Answers to bidder questions...
