The French Navy’s carrier strike group has departed for exercise ORION 26, a large-scale, high-intensity war game designed to test how France and its allies would fight and endure in a major conflict on Europe’s doorstep.
French carrier heads west for combat rehearsal
Flagship aircraft carrier Charles de Gaulle sailed from Toulon on 27 January, leading a powerful escort for the first phase of ORION 26 in the Atlantic. The exercise will unfold over several weeks in waters Paris describes as a “strategic area of manoeuvre” for the defence of European interests.
While the navy has not formally published the full order of battle, naval observers in Toulon watched a substantial group get underway. Alongside Charles de Gaulle, the following ships were seen leaving port:
- Air-defence FREMM frigate Alsace (D652)
- Horizon-class air-defence destroyer Chevalier Paul (D621)
- Italian Horizon-class destroyer Andrea Doria (D553)
- Replenishment ship Jacques Chevallier (A725)
As is standard practice, a nuclear-powered attack submarine is almost certainly shadowing the group, adding a hidden protective layer beneath the surface.
The escort mix leans heavily toward air defence, with three specialist anti-air warfare ships guarding the carrier — a strong signal about the threats being rehearsed.
Why ORION 26 matters for Europe
ORION 26 is not just another naval drill. It is the French armed forces’ main high-intensity training event of the decade, involving land, air, sea, cyber and space units in a single, complex scenario.
The French military frames the exercise as a stress test: can national forces, reinforced by allies, sustain demanding operations in a contested environment while facing simultaneous threats in multiple domains?
For Paris, the answer needs to be yes. The exercise comes as European governments worry about the durability of NATO, persistent Russian aggression and a global climate of strategic competition, from the Atlantic to the Indo-Pacific.
French commanders view ORION 26 as a bridge between today’s crisis management missions and the kind of brutal, large-scale combat that many in Europe hoped had been left in the past.

A fictional crisis designed to feel uncomfortably real
To keep the training sharp, ORION 26 uses a detailed political and military storyline. The exercise centres on two invented states: Mercury and Arnland.
Mercury is portrayed as an expansionist power trying to block Arnland’s move towards the European Union. Over several months, Mercury wages a campaign of “hybrid” actions: disinformation, cyber attacks, the use of proxy militias and covert support to armed groups inside Arnland.
By early 2026, the situation tips towards open conflict. Arnland, portrayed as a French ally, calls for help. France then takes command of a coalition under the ORION banner to stabilise the crisis and deter further aggression.
Within that framework, the carrier strike group has a clear mission: secure the maritime and air approaches, support land forces ashore and demonstrate that France can project serious power quickly and at distance.
A unique European asset at the heart of the exercise
The French Navy repeatedly describes its carrier strike group as a “unique strategic asset” in Europe. The United Kingdom also operates a carrier group, but France is the only EU state with a nuclear-powered aircraft carrier and an integrated air wing capable of sustained high-intensity operations.
With ORION 26, Paris wants to show that this asset is more than a prestige symbol. The group is expected to practise:
- Long-range air defence of coalition forces
- Strikes against targets deep inland
- Protection of sea lines of communication in the Atlantic
- Joint operations with land and air units during a large amphibious manoeuvre
The presence of an Italian destroyer within the screen underlines another point: France wants its carrier to be firmly embedded in regional defence plans, not operating in isolation.
What each service brings to ORION 26
ORION 26 is spread across the French armed forces, with large formations committed on land, at sea and in the air. The scale gives a sense of how seriously Paris is taking the exercise.
| Service | Key assets involved |
|---|---|
| Army | 3 combined arms brigades, 2,150 tactical vehicles, 40 helicopters, 1,200 drones |
| Navy | 1 carrier strike group, 2 amphibious assault ships (LHDs), 50 aircraft, 25 major surface combatants |
| Air force & space | 50 aircraft, 2 medium-altitude long-endurance drones, 6 air defence systems, 20 space-based sensors |
In total, 24 countries are taking part. That multinational character adds real friction: different procedures, different languages and different equipment all have to be meshed into a functioning coalition.
High-intensity focus and air-defence heavy escort
The composition of the carrier’s escort stands out. With three high-end air defence ships guarding the group, ORION 26 clearly places priority on surviving saturation missile and air attacks.
Horizon-class destroyers and FREMM frigates are equipped with sophisticated radars and surface-to-air missiles designed to fend off modern anti-ship threats. In a high-intensity scenario, the carrier would be a prime target for long-range missiles, drones and submarines.
During the exercise, the group is expected to rehearse layered defence: fighters intercepting threats at distance, ships engaging at medium range and close-in systems handling anything that leaks through.
The message is blunt: if an adversary tries to shut down access to the Atlantic through missiles and air power, France intends to keep that door open.
A response to a harsher strategic climate
Senior officers overseeing ORION 26 are candid about the context. They talk about “strategic competitors” using hybrid tactics to undermine European cohesion and weaken democratic societies.
That language reflects a shift in French thinking. The focus is no longer just on distant counterinsurgency operations or small-scale interventions. Instead, planners are asking how France would cope if a technologically capable opponent contested cyberspace, space, the electromagnetic spectrum and the information environment all at once.
For the carrier strike group, that means training not only for missile defence and strike operations, but also for fighting through jamming, spoofed signals and cyber intrusions aimed at command systems and logistics chains.
Key concepts behind ORION 26
Some of the terms used around ORION 26 can sound abstract. In practice, they relate to very concrete challenges for the forces at sea and ashore.
- High-intensity warfare: Large volumes of fire, heavier casualties and rapid consumption of munitions and fuel. For a carrier group, that means keeping aircraft flying and ships supplied under constant pressure.
- Hybrid actions: Activities below the threshold of open war, such as cyber attacks on ports, GPS interference, or orchestrated protests targeting military deployments.
- Joint and combined operations: “Joint” refers to cooperation between services of one nation; “combined” adds allied forces to the mix. ORION 26 requires both at once.
The logistical burden alone is significant. The presence of the new support ship Jacques Chevallier is part of a wider effort to ensure ammunition, aviation fuel and spare parts can keep flowing across long distances while the group operates at tempo.
What this means for future crises
Exercises like ORION 26 are designed to be uncomfortable. Planners insert unexpected events: a cyber attack on a fuel depot, a political restriction on airspace use, or an allied unit suddenly taken out of action. The aim is to see where the system bends or breaks.
For the French Navy and its partners, those lessons will feed directly into how future deployments are planned. If the Atlantic grows more contested, a carrier strike group that has rehearsed realistic worst-case scenarios stands a better chance of deterring an aggressor, or fighting through if deterrence fails.
Beyond the headlines, this deployment also signals something quieter but just as significant: European navies are re-learning how to think in terms of big wars, not just small crises. The wake of Charles de Gaulle in the Atlantic is part of that shift.
