North Korea’s newest warship was severely damaged during a launch ceremony Wednesday, with leader Kim Jong Un, who witnessed the accident, saying it brought shame to the nation’s prestige and vowing to punish those found responsible,

North Korea attempted to launch a new 5,000-ton naval destroyer on Wednesday, but the ship suffered a “major accident,” according to state media outlet KCNA, which reports the hull has been damaged. And North Korean dictator Kim Jong Un is not happy about it, to say the least.

It's not common for North Korea to acknowledge military-related setbacks, but observers say the disclosure of the failed ship launch suggests that Kim is serious about his naval advancement program.
