North Korean leader Kim Jong Un observed the test firing of a strategic cruise missile and evaluations of anti-ship, anti-submarine and air defense systems aboard the naval destroyer Kang Kon, state media KCNA reported on Sunday.
The tests were conducted on Friday as part of an assessment of the newly built warship's combat systems.
They included checks of target-detection and information-processing capabilities, integrated firepower systems, naval guns, automatic cannons and electronic warfare equipment, KCNA said.
Kim was briefed on the vessel's weapons evaluation program before watching the strategic cruise missile launch and other tests, according to the report.
KCNA said Kim hailed recent advances in weapons development and called for further efforts to expand North Korea's war deterrence and combat capabilities.
Kang Kon to commission into naval service, construction of two warships per year
He ordered officials to complete trials of the Kang Kon and commission the destroyer into naval service within two months, KCNA said.
Late last month, North Korea commissioned the 5,000-ton destroyer Choe Hyon and announced plans to deploy the Kang Kon, a vessel of the same class, as part of a broader naval modernization drive.
Kim has called for the construction of two warships of the class every year over the next five years and also outlined plans for larger 10,000-ton warships.
The Kang Kon was repaired last year after partially capsizing during a launch ceremony.
