Fabulously complicated and only producible with exotic emitters, sensors, and high frequency ICs.
Probably as easily jammed or forced into calibration state with a directed low frequency em pulse generator.
High tech garbage. We will not fare any better than Ukraine relying on tech like this.
Fortunately someone recently posted a real technological wonder - the F-14 cpu, old timers were messing with multithreaded compute while I was muddling along learning pong line by line from a hobbyist magazine.
