A group of scientists is claiming THAAD cannot effectively defend South Korea from ballistic missile attack:
Another scientist, David Wright, co-director of the Union of Concerned Scientists’ Global Security Program, said that a salvo of North Korean short-range missiles could overwhelm THAAD.
The 10 million people living in Seoul will also not be protected by THAAD, since it is being installed 125 miles south of the city. “It cannot engage missiles fired at Seoul, so it offers no additional protection of the city,” David Wright told the Associated Press.
“We have a layered defense systems, which is shared with the Republic of South Korea and Japan,” Commander Gary Ross, a Pentagon spokesperson, told Business Insider in response to whether or not Seoul was protected. “But we don’t discuss specific weapons systems.”
As it stands, US Patriot Advanced Capability-3 missile defenses provide protection for Seoul, though it has similar limitations to THAAD.
One scientist was even more wary of THAAD’s capabilities. Harris’ statement about THAAD is “technically incorrect,”Theodore Postol, a professor at the Massachusetts Institute of Technology, said.”The THAAD interceptor is very easily defeated by either causing a missile to tumble end over end or by intentionally fragmenting a rocket into pieces.”
In the case of a saturation attack, or a large volume of missiles as Postol described, THAAD’s defense capabilities “can be expected to be very low, probably zero or close to that,” Postol said. [Business Insider]
You can read more at the link, but of course if North Korea masses enough ballistic missiles at one location and there is not enough Patriot and THAAD interceptors to shoot them down then ballistic missiles will get through. When it comes to Seoul, North Korea can already destroy Seoul with artillery why waste ballistic missiles by shooting at it?
It seems they would want to use their ballistic missiles to target areas further to the south that their artillery systems cannot reach. Additionally as mentioned in the article THAAD is not the only missile defense system in South Korea with Patriot batteries deployed across the peninsula. THAAD has never been sold as being a magic force field to protect all of South Korea, it is part of a layered missile defense system to protect the country.
