NATO has released striking new footage from Exercise Ægir 25 in Norway, capturing the moment the submarine KNM Uthaug launched a torpedo that successfully struck and sank the decommissioned frigate KNM Trondheim. The controlled test, carried out as part of a broader naval readiness operation, was designed to confirm the destructive capability and precision of the weapon system under real conditions.

During the exercise, the KNM Uthaug executed a covert approach before firing the torpedo, which tore through the frigate and sent it to the depths. The Norwegian Armed Forces emphasized that the purpose of the demonstration was to validate the operational power of the submarine fleet—highlighting its ability to remain hidden, control the tempo of conflict, and deliver decisive strikes when required.

Officials underscored that submarines remain one of the most strategically influential assets in modern warfare, combining stealth, endurance, and overwhelming firepower. The footage serves as a reminder of the continuing importance of undersea capability within NATO’s defense posture, particularly at a time when maritime security is increasingly central to global stability.

The successful torpedo demonstration reinforces the message that NATO’s naval forces remain fully equipped, fully prepared, and fully capable of deterring threats across the North Atlantic and beyond.
