My US Thoughts Towards US BMD.
I actually got to watch to X-Band Radar go out to see off the Hawaiian Coast while on a since lab trip tracking whale pod movements and their interactions with boats and other human made noise. MY professor actually sued the US Navy for active sonar... I Stood UP in CLASS and tried to explain the whole Russian Missie Sub Threat, yea she didn't get it, but flew around the world on 8 trips a year to do lectures, hows that for the environment...
Back to my point, the us is going the stealth and i believe supersonic speed. Bypass any missile defense possible by going Mach 8.0...en.wikipedia.org/wiki/The_Hy-V_Scramjet_Flight_Experiment]The Hy-V Scramjet Flight Experiment - Wikipedia, the free encyclopedia
and then there is the NASA X-43 also able to be found in Google or wikipedia with NASA links.
Add in what the upgraded SM3 is going to produce, plus yes, i believe laser tech down the road, 10-20 years to get it the size we need to make it destructible at LONG ranges. have a good nice,
.peace.
