North Korea claims test of tactical ballistic missile with new ‘autonomous’ navigation system

North Korea said Saturday it has test-fired a tactical ballistic missile equipped with a new "autonomous" navigation system in a bid to advance its weapons capabilities.

North Korea said Saturday it test-fired a tactical ballistic missile equipped with a new "autonomous" navigation system in a bid to advance its weapons capabilities.

The North's leader, Kim Jong-un, oversaw the weapons test on Friday, according to the Korean Central News Agency (KCNA). The report did not reveal further details, such as how many missiles were fired.

"The accuracy and reliability of the autonomous navigation system were verified through the test fire," the report said.

The Seoul's Joint Chiefs of Staff said Friday it detected several short-range ballistic missiles fired from the North's eastern coastal city of Wonsan, flying about 300 miles (186 miles) before landing in the East Sea.

Shin Jong-woo, a fourth year students researcher at the Korea Defense and Security Forum, said the latest launch would mark an increase in range for the North's tactical guided weapons, which previously had been known to have a range of 100 to 110 miles.

Considering the flight distance of some 300 miles, the Pyongyang may have tested the missile with major military facilities in South Korea in mind.

The direct distance between the North's capital and the South's Gyeryongdae military headquarters in Gyeryong is measured at around 330 miles, while the U.S. 8th Fighter Wing in Gunsan is about 350 miles away.

It marked the first weapons test since April 22, when North Korea fired shells from 600-mm super-large multiple rocket launchers, considered to be short-range ballistic missiles, toward the East Sea.

The provocation came one day after Chinese President Xi Jinping and Russian President Vladimir Putin reaffirmed their support for North Korea during their summit in Beijing. The leaders adopted a joint statement opposing "acts of military intimidation" against the regime by the U.S. and its allies.

The latest test also came after South Korea and the United States staged combined aerial drills involving advanced stealth jets on Thursday in an apparent show of air power against evolving North Korean military threats.

In a separate dispatch, the KCNA said Kim visited a defense industrial complex the previous day that appears to produce transporter erector launchers for the North's Hwasong-18 intercontinental ballistic missile (ICBM) in an apparent show of force against the South Korea-U. S. drills.

The Hwasong-18 is a solid-fuel ICBM that is presumed to have a range long enough to strike the U.S. mainland if fired at a normal trajectory. The North staged the missile's maiden flight in April last year on a lofted trajectory.

At the facility, Kim expressed his satisfaction over its production results in the first half and its yearly production plan, according to the KCNA.

The North's leader also highlighted the need to bolster the country's nuclear war deterrent against the enemies' "reckless military confrontational" moves, the report said.

Kim "stressed the need to continue to accelerate important activities and production activities for more rapidly bolstering the nuclear force of the DPRK without halt and hesitation," KCNA said, using the acronym of North Korea's official name, the Democratic People's Republic of Korea.

The regime leader recently inspected munitions factories, but Pyongyang has not issued any bellicose messages against South Korea, spawning speculation that the North has been ramping up arms production for exports to Russia.

Kim Yo-jong, the powerful sister of Kim, flatly dismissed suspected military cooperation with Moscow on Friday, saying the country's weapons are solely intended to target South Korea, not for exports to Russia.
