North Korea said on Friday it had righted a capsized 5000-tonne Choe Hyun Class destroyer and moored it at a pier in the northeastern port of Chongjin as it continues to repair the new warship.

North Korea’s official Korean Central News Agency said experts will closely examine the ship’s hull before beginning the next phase of restoration, which will take place at a dry dock at the neighbouring port of Rajin and is expected to last seven to 10 days.

Satellite images taken on Thursday showed the stricken destroyer upright and floating. It wasn’t immediately clear from the image just how much damage had been done to the vessel, which had been in the water for days after the failed launch. But it did not appear to be listing.
