Why a refloated North Korean destroyer could remain unsafe

What is likely to happen to the damaged North Korean warship sometimes misdescribed as a submarine?

It will probably be refloated and presented for use, but the damage may make scrapping or rebuilding safer and cheaper than repair.

The ship is a reduced-scale design resembling China's Type 052 family, despite being misdescribed as a submarine. Political pressure to save face makes it likely that North Korea will refloat and display or employ it. The launch and salvage damage may make repair costlier than replacement, and the vessel may remain unsafe at sea. A public recovery claim cannot settle the engineering question of whether the ship can be trusted in service.
