According to Norwegian authorities, the objective of the launch was to test, verify and demonstrate the offensive power of the submarine’s weapon system, as well as to assess its employment capability in real combat scenarios. The destruction of the frigate served as proof of concept to validate the weapon’s lethality and precision.

The Armed Forces highlight that submarines represent one of the most strategic elements of modern naval power: they operate discreetly, have high autonomy and can dictate the pace of battle by remaining hidden and ready to strike.
The exercise included several Norwegian units, as well as assets from the United Kingdom’s Royal Navy and forces from Poland, reinforcing multinational cooperation within NATO.

The operation was released with the alliance’s official hashtags: #WeAreNATO, #StrongerTogether, and #DeterAndDefend.
