Neptune Strike 26-3 Validates NATO's Ability to Command and Integrate Allied Forces

Story by JFCNF Public Affairs

Neptune Strike 26-3, conducted from 17–23 July 2026, demonstrated NATO's ability to command and integrate multinational forces during multi-domain operations across the High North, North Atlantic and multiple areas of responsibility (AORs). Led tactically by Naval Striking and Support Forces NATO (STRIKFORNATO), the activity brought together carrier and expeditionary strike groups, Standing NATO Maritime Forces, submarines, air assets, and intelligence, surveillance and reconnaissance (ISR) capabilities under a unified operational framework.

As one of NATO's enhanced Vigilance Activities (eVAs), Neptune Strike is a recurring series designed to strengthen collective defence, deterrence and year-round readiness through flexible, multinational training tailored to evolving operational requirements.

Neptune Strike 26-3 marked the first time the activity expanded into the High North and North Atlantic alongside eVA Arctic Sentry, led by Joint Force Command Norfolk (JFC Norfolk). Operating in one of the Alliance's most strategically significant regions, the activity demonstrated NATO's ability to extend its operational reach, integrate multinational capabilities and strengthen command relationships across the maritime, air and amphibious domains.

The activity also highlighted NATO's ability to synchronise operations across multiple areas of responsibility. Close coordination between JFC Norfolk, JFC Brunssum and JFC Naples ensured unity of effort through aligned planning, command and execution.

Operating under STRIKFORNATO's tactical command, Allied forces validated command-and-control structures, refined operational procedures and trained in the demanding Arctic environment. These activities enhanced regional awareness, strengthened the security of transatlantic sea lines of communication and improved NATO's ability to reinforce Europe rapidly during a crisis.

For participating nations such as Spain, Neptune Strike provided valuable experience operating beyond traditional areas of responsibility. Vice Admiral Juan Bautista Pérez Puig, Commander of the Spanish Maritime Forces Headquarters (COMSPMARFOR), highlighted the importance of operating in the High North to improve regional expertise, situational awareness and Allied interoperability.

Throughout the activity, Allied maritime, air and amphibious forces demonstrated integrated operational capabilities:

* The United Kingdom Carrier Strike Group, centred on HMS Prince of Wales, and the Spanish Expeditionary Strike Group, led by ESPS Castilla, operated alongside Standing NATO Maritime Group One (SNMG1) and Allied surface combatants. Integrated carrier strike, amphibious and maritime warfare training—including replenishment-at-sea, simulated maritime interdiction and cross-deck aviation with a French destroyer—demonstrated NATO's ability to combine national capabilities into a cohesive multinational force.

Reflecting on the Carrier Strike Group’s contribution, Commodore Richard Hewitt, Commander of the United Kingdom Carrier Strike Group, said:
"Over the past three months, we have proven the UK Carrier Strike Group’s capabilities repeatedly, committing this capability to NATO and demonstrating our determination to defend NATO’s northern flank. We have shown how we can generate and sustain combat power and, when called upon, defend our NATO and Joint Expeditionary Force Allies against threats in the High North and North Atlantic. Neptune Strike has provided a successful conclusion to this period, demonstrating our capability and supporting NATO deterrence across the Euro-Atlantic area."

* Air operations showcased multinational integration across the Alliance. UK F-35B Lightning aircraft conducted long-range missions supported by Royal Air Force Voyager, French A330 Multi-Role Tanker Transport (MRTT) and Italian KC-767 aerial refueling aircraft. The NATO Intelligence, Surveillance and Reconnaissance Force (NISRF) further enhanced situational awareness and supported commanders' decision-making.
* Led by the Spanish Expeditionary Strike Group, more than 700 Spanish Marines rehearsed planning for expeditionary operations in the High North. While no amphibious landings were conducted, the planning process strengthened multinational coordination, demonstrating NATO’s ability to rapidly assemble and synchronise multinational amphibious capabilities should operational requirements require it.
* Allied forces also integrated autonomous systems alongside crewed platforms to enhance intelligence collection, logistics support and maritime awareness. During Find-Fix-Track (F2T) operations, NATO AWACS aircraft and the NISRF improved detection and tracking, while autonomous maritime systems increased operational flexibility and reduced risk to personnel.

Conducted alongside Arctic Sentry and Baltic Sentry, Neptune Strike 26-3 validated NATO's ability to integrate operational headquarters, maritime forces, carrier and expeditionary strike groups, air assets and supporting capabilities within a unified command-and-control structure. By training together in the Arctic, Allied forces strengthened overall readiness and their ability to preserve freedom of navigation and respond rapidly to emerging challenges.

Reflecting on the activity, Commodore Donald Mackinnon, Assistant Chief of Staff for Operations at Joint Force Command Norfolk, said:
"Neptune Strike 26-3 demonstrates NATO's ability to integrate maritime, air, land and multinational forces across one of the Alliance's most strategically significant regions. Operating in the High North and North Atlantic strengthens our readiness, reinforces interoperability among Allies, and ensures we can command and synchronise multi-domain operations as required."

Neptune Strike 26-3 forms part of JFC Norfolk's wider programme of enhanced Vigilance Activities across the High North and North Atlantic. Together with Arctic Sentry and Baltic Sentry, it reinforced NATO's collective defence and deterrence while strengthening command relationships and interoperability that will inform future activities, including the final 2026 iteration, Neptune Strike 26-4, later this year.
