Jammers will often cause radars to give a range estimate of several hundred miles until "burn thought" at around 25nm. If you assume that radar data to be accurate you now have an object covering hundreds of miles in the time of a single radar sweep only to apparently decelerate to a couple of hundred knots.
If that is your starting point where you start talking about the energy requirements and materials that can handle such huge forces you have done yourself a huge disservice by not questioning the accuracy of the radar data first.
