During the launch ceremony the previous day, North Korean leader Kim Jong Un vowed to rapidly strengthen the country's navy by building two destroyers per year to deter aggression, with the third and fourth ships of the new Choe Hyon class planned for 2026.

North Korean leader Kim Jong Un inspected military industrial factories, calling them to expand production of shells that meet modern warfare needs, state media KCNA said on Saturday.

North Korea says it has repaired its damaged second destroyer and launched it into the water in the presence of leader Kim Jong Un.
