North Korea has unveiled a nearly completed nuclear submarine, while Kim Jong-un criticized South Korea's acquisitions of similar technology.

North Korea has published photographs of a nearly completed nuclear submarine, following a visit by leader Kim Jong-un to a shipyard. He inspected a massive 8,700-ton vessel, covered with anti-corrosive paint, and stated that the completion of the submarine will strengthen the country's nuclear capabilities. Kim criticized South Korea's efforts to acquire a nuclear submarine, considering them an offensive act.

The North Korean submarine, referred to as a "strategic nuclear attack submarine," could be equipped with nuclear weapons and may be tested at sea in a few months. There are also discussions about possible sources of technology and resources for the construction of the submarine, including a potential collaboration with Russia. Tensions on the Korean peninsula have increased, especially after North Korea accelerated its nuclear program and strengthened relations with Moscow.
