ATM the biggest problem for LRAD is cost, you fire a $12K Patriot missile to intercept what is either a $40 million jet or a $300 drone. This is revolutionary.

Directed energy (laser) will solve this issue, so that Patriots are only engaged for expensive planes, while lasers will destroy drones and cheap ballistic rockets

No, lasers will not be a sufficient defense against ballistic missiles. Lasers require time to burn through the target. With ballistic missiles, they're facing a target traveling 5+ times the speed of sound (ie. little time), that also has heat shielding on the bit that's facing the target. Not to mention adverse weather conditions. And missiles w

Lasers will, however, be very effective at SHORAD, especially against cheap drones, rockets, artillery shells and cruise missiles, in the proper conditions. Iron Beam is projected to cost $0.50-$1.00 in electricity per shot, compared to a $50-60k Iron Dome interceptor missile (which is already insanely cheap for what it is).
