no one knows it's energy usage or range, those are classified. it has however been tested hitting a 1 coin at over 1 mile away and has repeatedly been able to shoot down both drones and mortar shells from over 2 miles away. the weapon can be fired for around 10 seconds at a time with a total cost of less than 10 total (just under 1 a second). one person said it uses the equivalent energy of running a space heater for about 1 hour per 10 second shot. we do not know how long between firing it needs to be fired again.  it can be mounted on buildings, ships and even armoured vehicles and should be ready by 2027. almost everything about it's technical specifications is top secret and any information you've read on it is purely speculation outside of what i have just mentioned.
