SEOUL, April 14 (UPI) — North Korean leader Kim Jong Un oversaw the test-firing of strategic cruise missiles and anti-ship missiles from a 5,000-ton naval destroyer, state media reported Tuesday, as he called bolstering nuclear deterrence the country’s “most important priority task.”

The North’s Choe Hyon destroyer launched two cruise missiles and three anti-ship missiles at island targets in the Yellow Sea on Sunday, the official Korean Central News Agency said.

The cruise missiles flew for roughly two hours and 12 minutes before striking their targets, KCNA said, while the anti-ship missiles flew for about 33 minutes.

The test was “aimed at checking the launching control line of the warship’s integrated weapon commanding system … as well as confirming the accuracy and the rate of hits of the improved active anti-jamming navigation system,” KCNA reported.

Pyongyang described the cruise missiles as “strategic,” a term it typically uses for systems capable of carrying nuclear warheads.

Kim observed the test-firing alongside senior defense officials and naval officers, KCNA said. Images published by state media showed Kim and the officials watching from an unspecified pier.

KCNA quoted Kim as saying the North’s “most important priority task [is] to steadily and unlimitedly bolster up the powerful and reliable nuclear war deterrent.”

“He clarified the important tasks for further strengthening the strategic and tactical attack capability, a key component of the nuclear war deterrent,” KCNA added.

Kim observed a pair of similar test launches last month, involving cruise missiles only.

Sunday’s expanded test may indicate the destroyer is nearing deployment, an official from South Korea’s Unification Ministry told Yonhap News Agency and other local reporters.

“It appears to be a final check of the weapons system if the test took place before the delivery of the Choe Hyon to the Navy,” the official said.

Pyongyang launched the Choe Hyon, its first 5,000-ton destroyer, last April, as Kim called for strengthening the country’s naval capabilities. Photos released by state media show the ship’s missile and radar systems resembling those found on Russian vessels, prompting speculation that Pyongyang received technical assistance from Moscow.

North Korea has deployed troops, artillery and weapons to support Russia’s war in Ukraine and is believed to be receiving financial support and advanced military technology in return.

A second destroyer, the Kang Kon, suffered an accident during its launch ceremony last year that left it listing on its side before it was repaired and relaunched in June.

KCNA said Kim was also briefed on plans for the weapons systems of two more destroyers currently under construction.

South Korean Rep. Yoo Yong-won of the People Power Party said earlier this month that commercial satellite imagery showed North Korea accelerating construction of a new warship at a shipyard in the western port city of Nampho.

“North Korea appears to be accelerating the modernization of its navy on the back of military technology assistance from Russia,” Yoo said.

Kim Jong Un has ordered a third 5,000-ton destroyer to be completed by Oct. 10, the anniversary of the founding of the ruling Workers’ Party of Korea.
