SEOUL, Oct 17 (Reuters) - North Korea conducted an underwater test of a new torpedo ​weapon system on Thursday to verify technological upgrades, state ‌news agency KCNA reported on Saturday, describing the test as a success and a significant step in the country's naval development.

The test verified propulsion technology ​developed through more than 180 tests over the past five ​years, KCNA said, adding that artificial intelligence was used ⁠for target detection and guidance in the new high-speed precision-guided torpedo.

The ​test is the latest in a run of North Korean weapons ​launches. It comes amid heightened tensions on the Korean Peninsula, as both Koreas race to develop weapons capable of evading missile defences.

The test was part ​of routine defence research activities aimed at advancing the country's weapons ​systems, KCNA said, adding that it demonstrated improvements in propulsion efficiency and the ‌performance ⁠of the torpedo's rocket propulsion system.

The latest test came after North Korea said it had tested two types of submarine-launched strategic cruise missiles on Wednesday to verify its navy's mission capabilities and the reliability ​of its war ​deterrent.

Pyongyang has ⁠been seeking to develop modern missile submarines alongside ballistic and cruise missiles, test-launching them from various platforms, ​including an aging submarine.

Meanwhile, South Korean President Lee ​Jae Myung ⁠oversaw the country's first test-firing of a domestically developed hypersonic missile last week.

Seoul's test of a hypersonic glide vehicle, a maneuverable weapon that can ⁠change ​course during flight, came days after ​North Korea said its leader, Kim Jong Un, had also overseen a test of an intermediate-range ​hypersonic missile.
