NATO’s Standing Naval Forces Join Exercise Polaris to boost maritime power and unity

English Channel – NATO ships from Standing NATO Maritime Group One (SNMG1) took part in Exercise Polaris 25 in the Northern Atlantic Ocean and English Channel. Led by France, this ten-day operational readiness exercise prepared naval forces for high-intensity combat, as they tackled multiple threats in a contested, complex environment - combining land, sea, air, cyber, seabed, cyberspace, space, electronic warfare and the information field.

The exercise took place between 12 May to 15 June 25, involving 3,000 military personnel alongside more than twenty surface ships and forty aircraft, including assets from the French Army, Navy and Air Force.

Participating nations included Brazil, Canada, France, Germany, Italy, the Netherlands, Norway, Portugal, Spain, the UK, the US and the NATO task group.

POLARIS 25 was a valuable exercise in which we operated as one team alongside our Allies, against our training opponents

UK–France-led amphibious drills in Devon, UK, was one of the largest such drills since WWII, featuring joint landings by Royal Marines, French naval infantry, Spanish and Italian troops, supported by 11 warships, helicopters and beachhead drills.

NATO units from Standing NATO Maritime Group One (SNMG1) participated in the French-led exercise Polaris 25. Over the course of 10 days in the Northern Atlantic Ocean and the English Channel, this operational readiness exercise integrated land, sea, air, cyber, seabed, cyberspace, space, and electronic warfare, creating a highly intense and complex scenario.

This was followed by an exercise-based naval confrontation between “Blue” and “Red” fleets, supported by submarines, frigates, aircraft, and multi-domain systems, allowing them to engage in realistic, high-intensity engagements. The dynamic and demanding nature of the exercise strengthened the operational agility and decision-making of all participants.

“POLARIS 25 was a valuable exercise in which we operated as one team alongside our Allies, against our training opponents,” said the SNMG1 Commander, Royal Netherlands Navy Commodore Arjen S. Warnaar. “Cooperation and collective efforts make us stronger against any threat — at sea and in the air.”

SNMG1’s participation underscores NATO’s commitment to deterrence, maritime security, and stability in strategically vital waters. Polaris 25 is crucial for reinforcing the task group’s readiness and ability to operate seamlessly within an international force.

As a defensive alliance, NATO remains committed to peace. Exercises such as this demonstrate its resolve and preparedness to deter any form of aggression.

SNMG1 is one of NATO’s four standing maritime task groups under the operational control of Allied Maritime Command (MARCOM). These task groups form the core maritime capability of NATO’s Allied Reaction Force (ARF) and provide a continuous maritime capability to execute NATO missions across the spectrum of operations, demonstrating solidarity and strengthening the bond and interoperability between Allied naval forces.
