SEOUL, Aug. 3 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) fired one ballistic missile into east waters from its west region, South Korea's Joint Chiefs of Staff (JCS) said on Wednesday.
The projectile was launched eastward from South Hwanghae province at about 7:50 a.m. local time, a JCS official said on the phone. Further details are being analyzed, the official added.
The launch came after the DPRK test-fired two medium-range Rodong ballistic missiles and one shorter-range Scud missile on July 19 in an apparent protest against the decision between Seoul and Washington to deploy Terminal High Altitude Area Defense on South Korean soil.
On July 8, South Korea and the U.S. abruptly announced an agreement to deploy one THAAD battery by the end of next year. Five days later, the deployment site was designated at Seongju county, some 250 km southeast of Seoul.
One day after the announcement, Pyongyang test-fired a submarine-launched ballistic missile (SLBM) off its east coast to demonstrate against the THAAD deployment decision. In times of military conflict, it is hard to detect and track SLBM with THAAD's X-band radar.
THAAD is incapable of intercepting Rodong and Scud missiles targeting South Korea as the DPRK missiles travel at an altitude of 20-30 km. The U.S. anti-missile system is designed to shoot down missiles at a much higher altitude of 40-150 km.
The DPRK military has threatened to take"physical measures" against the THAAD deployment site. On July 19, Seoul's unification ministry said Pyongyang appeared to have been in a state of conducting another nuclear test at any time given increased activity in its main Punggye-ri nuclear test site.
All of the four DPRK underground nuclear tests had been carried out in Punggye-ri since 2006. The latest took place in January this year.
China and Russia have strongly opposed to THAAD in South Korea as it raises tensions in Northeast Asia.
The U.S. missile defense system also breaks strategic balance in the region and severely damages security interests of China and Russia as the X-band radar can peer into Chinese and Russian territories.
Seoul claims that it will adopt the terminal mode radar with a detectable range of 600-800km, but it can be converted at any time into a forward-based mode capable of detecting at least 2,000 km. The modified version allegedly needs no conversion, spotting as far as 3,000-4,000 km.
South Korea's capital city and its adjacent metropolitan area cannot be protected by the THAAD battery as its interceptors have a maximum range of 200 km. Seongju is about 250 km away from the capital.
It's a clear evidence to support a claim that THAAD in South Korea is not aimed at intercepting DPRK missiles, but supervising and pressuring China and Russia as part of U.S. efforts at its Pivot-to-Asia strategy.
