Washington and Seoul are yet to comment officially on Thursday’s test.
Yoon Suk Yeol, the South Korean president, accused North Korea Friday of “reckless provocations.”
Ankit Panda, an analyst at the Carnegie Endowment for International Peace stated that footage from the launch on state television was the first time the world saw the missiles.
He said that the weapon could be similar Russia’s Poseidon underwater robot, but there are still questions.
According to KCNA, North Korea has been working on the underwater drone since 2012. The politburo representing the Workers’ Party of Korea was first informed about it in October 2021.
Although the country is equipped with dozens of nuclear warheads it isn’t certain if it has the technology to attach them to the new weapons it claims it has developed.
At a briefing Wednesday, Lieutenant General Scott Berrier of the U.S. Defense Intelligence Agency told reporters that while the U.S. would remain vigilant, Kim didn’t appear ready to conduct a nuclear test.
