North Korea developed the launching device for its submarine-launched ballistic missile (SLBM) by modeling it on a Soviet-era device imported from a Japanese trade partner in 2003, the head of a South Korean defense think tank said.
Hong Seong-min, who heads Security Policy Networks, said in an interview with the JoongAng Sunday that Pyongyang developed the device based on equipment once used for a now-retired Soviet submarine.
The arms expert added that it was imported via a Japanese trade dealer, citing a U.S. Congressional report drawn up in 2006 as evidence for his conclusions. The SLBM launching device is used to fire missiles from underwater.
