North Korea has developed an improved missile with a range of 180-300 km based on the Chinese Silkworm ground-to-ship missile.
"Since 2003, the North has kept testing the new KN-01 ground-to-ship missile," a government source here said Thursday. "It has now completed an improved version and deployed such missiles in South Hwanghae Province."
Until recently the KN-01 was believed to have a range of 160 km, meaning the North has managed to nearly double the range, making it easier to target South Korean ships in the West Sea.
Meanwhile, the South Korean military is staging an exercise in preparation for local provocations from the North on Friday, a day before the third anniversary of the North's shelling of Yeonpyeong Island.
The Ministry of Patriots and Veterans Affairs will mark the third anniversary of the shelling at the War Memorial of Korea on Saturday. http://english.chosun.com/site/data/html_dir/2013/11/22/2013112200741.html
