The main objectives for Neptune Strike 25-1, which began on Apr.1 and taking place across the entire Mediterranean are to maintain freedom of navigation and maneuver in NATO’s area of operations, to secure strategic maritime chokepoints, to conduct deterrence and vigilance, and to increase the interoperability in operational domains, fostering NATO’s capabilities to enable multi-domain operations across Europe, according to a NATO release.
Earlier on Saturday, ten NATO nations and Australia kicked off exercise At Sea Demonstration / Formidable Shield 25 (ASD/FS25), led by U.S. Sixth Fleet and executed by Naval Striking and Support Forces NATO (STRIKFORNATO), according to a Sixth Fleet release.
The release stated that ASD/FS 25 is the largest at-sea live-fire exercise in the European theater and that exercise is designed to enhance Allied interoperability in a joint, live-fire, Integrated Air and Missile Defense (IAMD) environment using NATO command and control reporting structures, “There is simply no substitute for the training and learning that occurs when we operate in these intensely realistic scenarios,” said Capt. Michael Dwan, Commander, Task Group 154.64 and STRIKFORNATO’s U.S. Maritime Ballistic Missile Defense Assets Advisor, in the release, “Training as a collective using NATO command and control reporting structure forges the bonds of interoperability and strengthens the alliance as a whole. Exercises like ASD/FS are critical for refining our collective integrated air and missile defense capabilities, ensuring we can respond effectively to any threat from any direction and maintain a credible deterrent posture.”.
ASD/FS 25 will include a series of live-fire events against unmanned air and surface systems, subsonic, supersonic, and ballistic targets, incorporating multiple Allied ships, multi-nation/multi-service ground-based air defenses, and aviation forces working across battlespaces and participating nations will share common tactical pictures and situational awareness, conduct NATO-level mission planning and engagement coordination, and exercise force-level pre-planned responses in various scenarios and situations, according to the release.
