Australian Strategic Policy Institute – Bill Sweetman writes that F-35 program leader Lieutenant General Greg Masiello delivered something of a lite-beer testimony to the Senate Armed Services Committee last week, with many questions deferred to a closed session. But the discussion pointed to a big and little-discussed change to air warfare technology – fighter radars so powerful that they can act as high-power microwave (HPM) weapons. And this involves not just the Lockheed Martin F-35 Lightning but also British Eurofighter Typhoons and the multinational Global Combat Aircraft Program (GCAP).
