Delay seen in launchpad construction

SEOUL — North Korea has stopped construction on a launchpad where intercontinental-range rockets could be tested, an interruption, possibly caused by heavy rains, that could stall completion up to two years, according to an analysis of new satellite imagery.

Despite the setback, however, Pyongyang is also refurbishing for possible future use another existing pad at the same complex that has been used for past rocket launches, according to the analysis of Aug. 29 images by 38 North, the website of the U.S.-Korea Institute at Johns Hopkins School of Advanced International Studies.

While the renovations don’t mean a launch is imminent, they indicate North Korea is preparing the site for possible future rocket tests, according to the 38 North special report, written by Nick Hansen.

North Korea conducted nuclear tests in 2006 and 2009, but experts don’t believe Pyongyang has yet mastered the technology needed to shrink a nuclear weapon so it can be mounted onto the tip of a long-range missile.

There are worries, however, about North Korea’s rocket and missile programs. The United States, South Korea and others have said North Korea uses rocket launches, including a failed effort in mid-April, as covers to test banned missile systems that could single out parts of the United States. North Korea says recent rocket launches were meant to put peaceful satellites into orbit.

“Despite the temporary halt in construction at the new Tonghae launchpad and the failed test last April, the North Koreans appear determined to eventually build bigger and better rockets,” said Joel Wit, a former U.S. State Department official and editor of 38 North.
