The Royal Norwegian Navy blew up all torpedoes remaining in the sunken frigate, Helge Ingstad, which sank as a result of collision with an oil tanker in November 2018.
Helge Ingstad was one of the most modern ships in the navy and cost over $500 million dollars. It sunk between the port city of Bergen and the North Sea.
The Navy already dealt with torpedoes on board the sunken ship. However, more ammunition will need to be reviewed before the remains can be raised.
