Today's Ballistic Missile Defense Systems rely upon Hit-to-Kill kinetic energy interceptors. GMD missile sites are located at Fort Greely, AK, and at Vandenberg AFB, CA. Regardless of what the MDA might tell you, hope we never have to use it!

This info is from 14 Aug 2012 and is projecting into the future because some capabilities are not yet there such as the East Coast Fire Control site (Ft Drum is a potential site and some money has been spent there but final location is still pending I believe. More interceptor missiles may or may not go somewhere on East Coast. Regardles,s there is a system of systems in place now.

Ballistic Missile Defense System (BMDS) is available now for detection and intercept of Ballistic Missiles. An overview of this series of multiple systems is at WWW.mda.mil/system/elements.html

JimE - I too am curious about what we have. We can detect threats, from almost anybody these days, but what do we do about it? Who knows. Nukes would have to be destroyed somewhere around their flight apogee, which is very high, and SCUD-type defenses such as the "Patriot" won't do. The high-power laser? Maybe, I think it shows some promise, but I have no idea where in the development cycle it is. Just keeping my fingers crossed that MAD is still viable, and that the nutty Korean, Kim, doesn't commit suicide by nuke.

Gene, I was looking at you latest post: Documents relating to Nekoma, ND. When I was a TSgt in the USAF I had the opportunity to tour this site during a 15th AF Inspection visit. To say I was impressed would be an understatement. The audio-visual presentation given bt the US Army was outstanding. I am curious to know what systems we have on line today to replace this ABM system.
