SEOUL, South Korea—North Korea defied international warnings and fired a long-range rocket Wednesday, the second launch under its new leader and a clear sign Pyongyang is pushing forward with its quest to develop the technology needed to deliver a nuclear warhead.
Pyongyang’s state media quickly claimed that the country had successfully put a peaceful satellite into orbit with its long-range Unha-3 rocket—the North’s stated goal of the launch. But South Korea and Japan said they couldn’t immediately confirm that. The launch was something of a surprise, as North Korea had indicated technical problems with the rocket and recently extended its launch window to Dec. 29.
A rocket expert said North Korea’s rocket appeared to have improved on an April launch, which broke apart shortly after liftoff, but that it might be a day before US officials could determine whether a North Korean satellite was circling the Earth.
The United Nations, Washington, Seoul and others see the launch as a cover for a test of technology for missiles that could be used to strike the United States.
South Korean Defense Ministry spokesman Kim Min-seok told a nationally televised news conference that a South Korean Aegis-equipped destroyer detected the launch at 9:51 a.m., local time, and the first stage fell into the Yellow Sea about a minute later; the rocket then flew over a South Korean island near the border with North Korea a minute after that. The rocket was seen flying west of Okinawa at 9:58 am, and then disappeared from South Korean radars, Kim said.
William Lewis, a spokesman for the US North American Aerospace Defense Command, which tracks such launches, had no immediate information about the reported launch.
Japan protested the launch and said one part of the rocket landed west of the Korean Peninsula and another part was expected to have landed east of the Philippines. South Korean President Lee Myung-bak planned an emergency national security council meeting Wednesday, and South Korean Foreign Minister Kim Sung-hwan warned that North Korea will face grave consequences.
Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics said officials would likely have to wait a day or so to see if the United States can track anything that might have been placed in orbit by North Korea.
Success would be defined as “something that completes at least one orbit of the earth,” he said. But “clearly this is much more successful than their last attempt. It’s at least as good as they’ve ever done. They’ve proved the basic design of it.”
