I guess the semi-secret 60,00 dollar question is what are cost effective drone defences? What do they look like and consist of, and how fast can we start mass-producing and improving them?
I.E., A re they jamming the drone communications? Or using a C.I.W.S. type shoot-down system at closer ranges? Interceptors that detonate close enough to the incoming drone to at least disable it or throw it off course? Bombing the country(s) making and supplying the drones?
Some combination of all these?
I think it’s a combination of CIWS and large numbers of defensive FPV drones. Others may have better ideas. And you’re not gonna bomb countries that make drone components unless you want us to declare preemptive war on China.
