Right now, the United States and South Korea are in discussions regarding the feasibility of deploying a Terminal High Altitude Area Defense, or THAAD system there, along with its associated radar, while nearby China has voiced objections to the idea.
No decision has been reached, but earlier this week Lt. Gen. David L. Mann, commander of U.S. Army Space and Missile Defense Command/Army Forces Strategic Command and Joint Functional Component Command for Integrated Missile Defense said such an emplacement would provide a "huge increase in capabilities," in South Korea to protect against threats posed by North Korea.
Mann is aware of China's concerns.
"This is a sensitive issue for the partners throughout the region, and we understand the sensitivities that are involved, especially when you look at South Korea is one of the largest trading partners to China in the region," Mann said. "We don't minimize the sensitivity of these discussions."
Right now, he said, discussions are about the feasibility of putting a THAAD battery in South Korea. The system is designed to strike down incoming missiles in their "terminal" phase. THAAD missiles don't carry warheads, but rather rely on their own weight combined with the speed at which they travel to strike down the missiles they target. A THAAD battery consists of launcher vehicles with each vehicle holding 8 missiles; a radar system; and a fire control system which serves as the communications and data-management backbone.
The THAAD system, he said, is designed to provide greater capability to address "more challenging threat vehicles that are out there." The THAAD system augments existing capabilities such as the Patriot Missile system and the Aegis Combat System.
"THAAD, if you look at its performance, especially in past testing, it's just remarkable what its capability has proven to be," Mann said, praising the system's capabilities.
Were such a system ever put into South Korea, Mann said, it would be focused not on China, but on threats coming from North Korea.
"That radar and that system is not looking at China," he said. "That system, if the decision is made to deploy it, would be oriented on North Korea, quite frankly, and threats posed by the North Korean military. It's a missile defense capability, to make sure we provide our South Korean partners as well as other partners in the region, with protection."
SABRE RATTLING
In recent months, North Korea has become more aggressive in testing potential weapons technology. In January, North Korea detonated what it claimed to be a hydrogen bomb. Last month, it launched an earth observation satellite into space. Mann said the North Koreans are making themselves a viable threat -- the kind of threat THAAD is designed to address.
"I think we need to take North Korea seriously," he said. Recent North Korean activity "shows that they have the capability for long-range flight. And so I would not minimize ... I think we need to take their capability seriously ... I think we need to take their developments very, very seriously."
Right now, the Army has a THAAD system in place in Guam, and Mann said that system is likely to stay there long-term. Were a decision to be made to place a THAAD system in South Korea, it could take several weeks to make happen, Mann said. While the system is mobile, site selection and site preparation will take some time.
The Army is looking at other locations for THAAD as well, Mann said. In addition to South Korea, he said, he believes Japan and other nations may also be interested in the system, but "to what degree I'm not prepared to say," he said.
Mann also said the Army is seeing a "demand signal' from other areas for such a capability, including from U.S. European Command, U.S. Central Command, and other areas
"If you look at their operation plan, they see a need ... for this capability," he said.
OVERTAXED PATRIOTS
The older Patriot Missile System has a mission similar to that of the THAAD system, though there are many more in the Army's inventory. The Army plans to have up to seven THAAD batteries, for instance, while it currently maintains 15 Patriot Battalions. Nevertheless, Patriot systems and crews are overtaxed, and Mann said it's not prudent to look to the THADD system to relieve that stress.
With just seven planned THAAD batteries, he said, "you have to be so judicious, so careful as to where you deploy THAAD, because you have so few ... of that defense system. It's complementary, but I don't think you are looking at THAAD necessarily as being able to alleviate the stress on Patriot, just by the sheer numbers and where we have Patriot located throughout the U.S., and the world."
Instead, he said, the Army is looking at other options that will enable it to more effectively use Patriot. One solution is purchasing a dismounted command and control system for the Patriot battery to allow for it to serve a wider area -- "instead of deploying a whole battalion we can maximize what that battalion brings to the table by not having to send the whole battalion, but by using the dismounted capability to take different components within the Patriot battalion to different locations and really kind of spread its capability ... on the battlefield."
Mann also said that instead of deploying an entire Patriot battalion -- including all the equipment that supports the launchers and missiles, "maybe we can take a Patriot battery to a location and augment its capabilities by leveraging an Aegis radar, or an Air Force radar, or a coalition radar, and really kind of componentize the Patriot unit and optimize its capabilities across a battle space. Leveraging networks to be able to get the best return on investment, in order to have the best sensor, best shooter mix to address a threat."
