Exercise Atlantic Lion was a large-scale multinational maritime and joint-arms training operation conducted in the North Atlantic theater. The exercise brought together naval, air, and land elements from a coalition of NATO members and partner states to rehearse anti-submarine warfare, carrier strike group operations, amphibious assault, and logistics under contested conditions. It drew strategic planners from allied headquarters, defense ministries, and multinational commands to evaluate interoperability, command-and-control, and sustainment across sea lines of communication.
The planning for the operation drew on precedents such as Exercise Trident Juncture, Baltops, Exercise Cold Response, Steadfast Defender, and historical maneuvers like Exercise Ocean Venture. Strategic concepts referenced included doctrine from NATO Allied Command Operations, lessons from the Falklands War, and capability development inspired by Carrier Strike Group 21 and RIMPAC. Political context involved diplomatic frameworks shaped by the Treaty of the North Atlantic, recent crises near Crimea, tensions involving Kaliningrad Oblast, and security debates in capitals including London, Washington, D.C., Brussels, and Reykjavík.
Planners set objectives echoing priorities of NATO Defence Planning Process, addressing anti-submarine warfare lessons from U-boat campaign studies, power projection seen in Operation Overlord amphibious doctrine, and maritime domain awareness emphasized after incidents like USS John S. McCain collisions. The scope encompassed integrated air defense rehearsals influenced by Operation Allied Force, carrier aviation cycles derived from USS Enterprise (CVN-65) operations, and logistics tested along lines similar to Operation ERINYS and Operation Atlantic Resolve. Participating staffs incorporated doctrine from Allied Joint Force Command Brunssum, joint procedures from Supreme Headquarters Allied Powers Europe, and interoperability standards from NATO Standardization Office.
A coalition of navies, air forces, and marine units assembled, including elements from United States Navy, Royal Navy, French Navy, German Navy, Royal Netherlands Navy, Norwegian Armed Forces, Spanish Navy, Italian Navy, Canadian Forces, Danish Armed Forces, Polish Armed Forces, Estonian Defence Forces, Latvian National Armed Forces, Lithuanian Armed Forces, and partner contingents from Sweden and Finland. Carrier strike groups associated with HMS Queen Elizabeth (R08), USS Gerald R. Ford (CVN-78), and FS Charles de Gaulle (R91) were present in various phases, together with submarine units such as HMS Astute (S119), USS Virginia (SSN-774), and FS Le Téméraire (S617). Air components included squadrons flying F-35 Lightning II, Eurofighter Typhoon, Dassault Rafale, F/A-18 Super Hornet, and maritime patrol aircraft like P-8A Poseidon and P-3 Orion. Amphibious forces were drawn from units with lineage to Royal Marines, United States Marine Corps, French Navy Commandos Marine, and Brigade Coastal Jaeger Units.
The operation unfolded over distinct phases mirroring exercises such as Reforger rotations and Bright Star timelines. Phase I concentrated on force assembly and maritime transit logistics via choke points near English Channel and GIUK gap corridors, invoking operational plans akin to Operation Neptune. Phase II simulated contested sea control and anti-submarine warfare in deep water inspired by Battle of the Atlantic scenarios. Phase III shifted to littoral operations, amphibious landings modeled on Operation Husky techniques, and urban stabilization rehearsals referencing Operation Sharp Guard. A final phase emphasized redeployment, casualty evacuation exercises influenced by Operation Medivac procedures, and after-action review cycles comparable to Combined Joint After Action Review practices.
Major evolutions included carrier air wing integration, underway replenishment drills like those in Operation Atalanta, complex anti-submarine exercises using towed array sonar tactics from SOSUS heritage, and electronic warfare scenarios recalling lessons from Gulf War (1990–1991). Surface action groups conducted live-fire events under rules derived from Code of Conduct for Naval Engagements and exercised cooperative engagement capability procedures similar to those used by Aegis Combat System operators. Amphibious assaults rehearsed beachhead seizure with doctrinal lineage to Normandy landings and Anzio, while special operations units executed maritime interdiction modeled on Operation Enduring Freedom approaches. Cyber defense evaluations referenced frameworks from NATO Cooperative Cyber Defence Centre of Excellence and interoperability trials used standards promulgated by the NATO Communications and Information Agency.
Operational assessments highlighted improvements in joint command interoperability consistent with recommendations from NATO Defence College studies, enhanced anti-submarine detection credited to techniques from Sonar Warfare School curricula, and logistics throughput gains reminiscent of Mulinary sealift analyses. Capability shortfalls cited by evaluators referenced sustainment constraints emphasized in reports from Congressional Research Service and lessons echoed by analysts at RAND Corporation and International Institute for Strategic Studies. Tactical innovations included refined carrier strike coordination comparable to procedures published by U.S. Fleet Forces Command and combined air defense solutions aligning with Allied Air Command priorities.
The exercise generated diplomatic reactions from capitals such as Moscow, Beijing, and regional actors including Reykjavík and Stockholm, with official statements invoking historical disputes like Nord Stream tensions and maritime rights debates tied to United Nations Convention on the Law of the Sea adjudications. Critics in parliaments including Stortinget, Bundestag, and House of Commons of the United Kingdom questioned cost and escalation risks, and non-governmental commentators at institutions like Chatham House and Carnegie Endowment for International Peace debated strategic messaging. Incidents during the exercise prompted bilateral consultations at NATO Headquarters and influenced follow-on diplomacy at meetings of the NATO-Russia Council and summits of the North Atlantic Treaty Organization.
