The 5,000-tonne destroyer, North Korea's second known, was damaged during its launch ceremony on May 21, leading Kim Jong Un to call it a “criminal act”.
The Centre for Strategic and International Studies reported the warship is now in a graving dock at Rajin Ship Repair Factory, with critical parts covered to limit visibility.
Experts say the ship's hull will be examined to determine restoration steps, with potential transfer to the fitting out dock for weapons and systems installation after repairs.
Kim Jong Un blamed officials for the failed launch, detaining several involved and ordering the ship's restoration before a ruling party meeting.
