Unha-3 was largely of North Korean manufacture

A team of South Korean analysts, assisted by US personnel, has completed a study of wreckage from the first stage of the Unha-3 satellite launch vehicle that was recovered following North Korea's satellite launch on 12 December 2012. According to local press reports, which cite a 21 January briefing by the South Korean Ministry of Defense, the vehicle was largely of North Korean manufacture, but some components had been obtained from five other countries, including China and a number of unspecified European nations.

None of this foreign hardware was military-specific, so was not covered by the Missile Technology Control Regime (MTCR). Press reports listed it as including a power-converter, pressure and temperature sensors, and wiring.

A day after South Korea released its report on the Unha-3 first stage, the UN Security Council adopted Resolution 2087 (2013), which expanded the travel ban and asset freeze on North Korea. Officials targeted included Paek Chang-Ho, described as a senior official and head of the satellite control centre of the Korean Committee for Space Technology, and Chang Myong-Chin, described as the general manager of the Sohae Satellite Launching Station and head of the launch centre used for the Unha-3 launches.
