North Korea's government stopped four people. This is because a ship they launched did not work. Kim Jong Un said they were very careless. News said this.

North Korea does not often punish its leaders for bad weapon tests. But this weekend, four leaders went to prison. This means Kim wants a strong army and people to follow rules.

On Wednesday, a big ship was hurt. It happened when Kim was there. A part broke off the ship when they were starting it in Chongjin. Pictures from space show the ship on its side with blue covers. Some of the ship is in the water.

Kim was very angry. The ship is important for his navy. Kim said it was a bad thing because people were not careful.

On Monday, the Korean news said the police stopped Ri Hyong Son. He works for the Workers Party. He said he was very sorry because the rocket did not fly.

KCNA said on Sunday that three people from the Chongjin Shipyard were held because of a problem. They were the main engineer, the boss of the hull workshop, and an office manager.

Hong Kil Ho worked at the shipyard. He was asked questions, said KCNA before.

North Korea said on Thursday that bad people will get a punishment. But we don't know what the punishment is.

Kim killed many people when he started to rule. He did this to be strong. Now, he is very strong. So, he does not kill people often.

Kim helps scientists who make weapons. He wants more nuclear weapons. He gave them new homes. Last year, a satellite launch did not work. Kim told the scientists it was okay. He said that not winning helps you to win, the news said.

Kim wants to make his weapons plan better. He started it in 2021. Kim says North Korea needs more ships and strong missiles. This is to be safe from the U.S.

Last month, North Korea showed a new, big ship. It can carry weapons. The leader said it helps their navy get better.

North Korea said the ship was not broken much. They said it had a scratch and some water went inside.

North Korea said on Friday it needs about 10 days to fix things. But many people think the damage is bigger.
