and the electric fields associated with the radio waves would amount to millions of volts per meter
If you could by some means focus all this RF power on a volume of air the size of one wavelenght, and the voltages work up to the many-mV/m range, you'd be mostly ionizing air.
I guess this would result in a very spectacular lightshow, and a missile could be severely damaged by both EM radiating from the discharge in mid air and the heat it delivers to that air.
However, I don't think that there is any feasible way to concentrate RF energy to a space the size of a wavelenght at any serious distance (i.e. over 100s of waveleghts away).
