S. Korea tests a submarine-launched missile ballistic missile

 South Korea successfully tested a submarine-launched missile ballistic missile (SLBM) at home, a military source reported Tuesday.

The military source said that the state-run Agency for Defense Development (ADD) conducted its first underwater ejection test of the SLBM from a domestically-developed 3,000-ton submarine on September 1, reports Xinhua news agency.

After a few more tests, the SLBM will become mass-produced and can be deployed.

It will be mounted on Dosan Ahn Changho's submarine equipped with six vertical launch tubes. The submarine was in commission since August 13.

According to reports, the SLBM was codenamed Hyunmoo 4-4’ because it was based on technology from the country's Hyunmoo-2B missile. It has a range of approximately 500 km.

It can be used with standard warheads.

Before the submarine launch last week, the military conducted a successful test of SLBM from an underwater barge.
