North Korea tested a railway-borne missile in its firing drills on Friday, a state media KCNA said on Saturday, amid a U.S. push for new sanctions against the isolated state after its recent series of weapons tests.
South Korea's Joint Chiefs of Staff said two short-range ballistic missiles SRBMs travelled approximately 430 km 267 miles to a maximum altitude of 36 km 22 miles after being launched eastward on the northwest coast of North Korea.
The official KCNA news agency did not say what the missiles range, or trajectory, but said a firing drill was held in North Pyongan Province to check and judge the proficiency in the action procedures of the railway-borne regiment. The country tested the rail-based system for the first time last September, and said it was designed as a potential counter-strike to any threatening forces.
Three ballistic missiles have been launched in a fast sequence of weapons tests since New Year's Day. The previous two launches involved what state media called hypersonic missiles capable of high speeds and manoeuvring after launch.
Hours before the latest test drill, North Korea slammed the United States for new sanctions in response to its recent missile launches, calling it a provocation and warning of a strong reaction.
On Wednesday, U.S. President Joe Biden imposed its first sanctions against Pyongyang and called for the UN Security Council to blacklist several North Korean individuals and entities.
North Korea has defended the missile tests as its sovereign right to self-defence and accused the United States of intentionally escalating the situation with new sanctions.
Kim Jong Un, North Korea's leader, did not attend the drill. KCNA said the military leadership had ordered the test at short notice and the system precisely hit the target set in the east coast with two tactical guided missiles. The system demonstrated high manoeuvrability and a rate of hits, KCNA said, leading to discussions to set up a proper railway-borne missile operating system across the country. North Korea is steadily developing its weapons systems, raising the stakes for stalled talks that aim to dismantle its nuclear and ballistic missile arsenals in return for U.S. sanctions relief.
South Korean Chung Eui-yong and US Secretary of State Antony Blinken condemned the latest launch during their phone call on Saturday and coordinated responses to the North's recent missile tests, the State Department said.
Both sides pointed out the importance of maintaining a firm combined readiness posture and urged Pyongyang to return to a negotiating table, Seoul s foreign ministry said.
The test could be an instant display of force against the U.S. sanctions push, as noted by Cheong Seong-chang, director for North Korean studies at South Korea's Sejong Institute, said it was not planned in advance and unusually took place in the afternoon.
It is a message that they will take an eye to eye approach if Washington presses for sanctions for testing non-long range missiles, Cheong said.
KCNA released pictures showing a column of smoke and flame as it was launched from the top of an olive-green train in a mountainous area, before arrowing down on a small island, sending up a cloud of smoke and debris as it hit.
Despite North Korea's limited and sometimes unreliable rail network, rail mobile missiles are a relatively cheap and efficient way to improve the survivability of their nuclear forces, making it hard for enemies to detect and destroy them before being fired, analysts said.
Kim Dong-yup, a former South Korea Navy officer who teaches at Seoul's Kyungnam University, said North Korea appears to have fired KN 23 SRBMs, which were also tested fired in September, when they flew 800 km 497 miles. First tested in May 2019, the KN 23 resembles Russia s Iskander-M SRBMs, and is designed to evade missile defences and conduct precision strikes.
