The Aegis BMD system with it's SM-3 missiles looks like a great system but probably doesn't have the range to take on the NK ICBM.
In fact the SM-2, SM-3 and PAC-3 systems all look like theater defense systems to me. Not clear that we would be close enough to the launch to take out the NK missile.
There is some good background information on the SM-3 and the Aegis system at this website
Here is a key paragraph:
The Aegis BMD weapon system went to sea September 30, 2004. Raytheon began delivering Standard SM-3 initial deployment missile rounds to the Missile Defense Agency (MDA) October 22, 2004. Five additional missiles were delivered to MDA in December 2004 to support missile deployment on destroyers and cruisers. Aegis BMD will protect not only the United States, but also US allies and US troops deployed around the globe against short to medium range ballistic missiles. SM-3 has been under testing since January 2002 intercepting targets in space four times.
Note that the system is for short and medium range ballistic missiles. I think the NK missile is in the long range class. Hoping I'm wrong about this. I would love to see us take out that SOB's latest toy.
Thanks for the link and information. Having short and medium range defense missiles near enough to what we want to defend is key to their effectiveness. And although it's been public news in years past, many would be surprised to know of some of the places those defenses are already posted.
