Zam-2.0: North Korea tests high-speed AI-guided torpedo; what we know

North Korea has tested a new artificial intelligence-equipped torpedo designed to detect and guide itself towards targets, as Pyongyang steps up efforts to strengthen its naval capabilities and develop weapons that could pose a greater challenge to South Korea and the United States.The high-speed, precision-guided torpedo, identified as the Zam-2.0, was tested underwater on Thursday to verify technological upgrades, North Korea's state-run Korean Central News Agency (KCNA) reported on Saturday. The agency described the test as a success, saying it demonstrated improvements in propulsion technology and marked a potentially significant advance in the country's naval development.The test follows North Korea's underwater launches of two types of strategic cruise missiles on Wednesday, its first publicly reported underwater missile tests in nearly three years, according to The Washington Post.
