Significant resources have been allocated to the national space program, which is managed by the National Aerospace Development Administration (formerly managed by the Korean Committee of Space Technology until April 2013) Domestically produced launch vehicles and the Kwangmyŏngsŏng satellite class are launched from two spaceports, the Tonghae Satellite Launching Ground and the Sohae Satellite Launching Station. After four failed attempts, North Korea became the tenth spacefaring nation with the launch of Kwangmyŏngsŏng-3 Unit 2 in December 2012, which successfully reached orbit but was believed to be crippled and non-operational. It joined the Outer Space Treaty in 2009 and has stated its intentions to undertake crewed and Moon missions. The government insists the space program is for peaceful purposes, but the United States, Japan, South Korea and other countries maintain that it serves to advance military ballistic missile programs.
