The Democratic People's Republic of Korea (DPRK) conducted an ejection test for a submarine-launched ballistic missile (SLBM) last month, South Korea's Yonhap news agency reported Wednesday citing a military official.
The DPRK's SLBM was believed to have been tested in an initial phase as it was an ejection test, not a full flight test. Under the ejection test, the missile flies just hundreds of meters after being ejected from waters.
The Seoul military official was quoted as saying that the December test was a failure, noting that the DPRK has continued such ejection tests.
