The NATO has concluded the first iteration of its enhanced Vigilance Activity, Neptune Strike 26, on March 31, 2026. The exercise, led by Naval Striking and Support Forces NATO, took place across the Western and Central Mediterranean.

 

Launched on March 25, the activity focused on integrating advanced maritime strike capabilities in a multi-domain environment. NATO said the exercise reinforced its readiness, cohesion and ability to respond to evolving security challenges.

The operation brought together expeditionary and carrier strike groups from across the Alliance. Officials said the exercise demonstrated NATO’s ability to project credible deterrence while maintaining flexibility.

Forces from multiple Allied nations participated, including Albania, Bulgaria, Croatia, Finland, France, Germany, Greece, Italy, the Netherlands, Romania, Spain and the United States. The exercise highlighted the level of cooperation among NATO members operating in a strategically significant region.



Key formations included the Spanish Navy’s Juan Carlos I expeditionary strike group and the Italian Navy’s Cavour carrier strike group. These units operated alongside the French Navy’s Charles de Gaulle carrier strike group in coordinated operations.

NATO said the exercise demonstrated a high level of interoperability among participating forces. Units operated across maritime and air domains while synchronizing capabilities and procedures in a complex environment.

Officials attributed this level of integration to sustained investment in joint training and shared operational standards. The exercise also emphasized NATO’s ability to operate effectively in multi-domain scenarios.

All activities were conducted in accordance with international law. NATO said the exercise remained adaptable to current security conditions.

The Alliance described Neptune Strike 26 as a demonstration of its commitment to deterrence and defense. Officials said the exercise supports stability across NATO’s area of responsibility, particularly along its southern and southeastern flank.
