North Korea said Saturday that it had conducted an underwater test of a new high-speed, precision-guided torpedo system using artificial intelligence for target detection and guidance.

The Zam-2.0 system was tested Thursday to verify technical upgrades, according to the state-run Korean Central News Agency, as reported by Yonhap and the South China Morning Post. KCNA said the test demonstrated technology intended to improve propulsion efficiency and rocket propulsion systems. It added that more than 180 related tests had been conducted over the past five years but disclosed no further specifications.

North Korean defense officials described the test as a success that could bring a significant change to the development of the country’s navy, according to KCNA.

The announcement followed another naval weapons test Wednesday, when North Korea launched two types of strategic cruise missiles from what was believed to be a 3,000-ton submarine in the East Sea, Yonhap reported. The launches marked North Korea’s first submarine-launched cruise missile test in nearly three years, according to USNI News.

Pyongyang has also recently commissioned two 5,000-ton destroyers, the Choe Hyon in the West Sea and the Kang Kon in the East Sea.
