According to Snopes, the footage was filmed as the Norwegian navy fired on one of its own ships to test its new missile. The recently-decommissioned naval ship KNM Trondheim was used as target for testing Norway’s Naval Strike Missile and the video shows it exploding into a massive fireball on being hit.

Norwegian Navy Test Missile Strike - commentary:
This is the dramatic moment a ship is blown up to demonstrate a powerful new missile. The Norwegian armed forces took a decommissioned frigate out into the sea for a game of target practice. They then fired the new 'Joint Strike Missile' at the vessel with pinpoint accuracy, causing a huge explosion and major damage to the vessel.
