The incident, which Western sources described as an act of intimidation, underscores the rising tensions between France and Russia in this strategically sensitive region. According to the French Armed Forces General Staff, the use of a fire-control radar—a system designed to lock onto a target before launching a missile—signals hostile intent.
Despite the encounter, the French aircraft continued its mission, which involved monitoring critical underwater infrastructure in the Baltic Sea, without altering its course or responding to the Russian action. This marks the second time in recent months that an Atlantique 2 has been illuminated by Russian radar, following a similar incident in January involving an S-400 air defense system based in Kaliningrad.
The event over the Baltic Sea was not an isolated occurrence. Earlier this month, on March 4, a French Air and Space Force MQ-9A Reaper drone faced aggressive maneuvers from a Russian Su-35 fighter jet near Crimea in the eastern Mediterranean.
That encounter prompted French Defense Minister Sébastien Lecornu to denounce the Russian actions as “intentional, unprofessional, and aggressive,” emphasizing France’s resolve to maintain operations in international zones.
These repeated incidents highlight a pattern of Russian military interactions with French assets, raising questions about the broader geopolitical dynamics at play.
The Baltic Sea incident, in particular, occurred as the Atlantique 2 was conducting surveillance under the NATO-led Operation Baltic Watch, a mission focused on safeguarding underwater infrastructure amid growing concerns over sabotage in the region.
The French Armed Forces General Staff explained that the use of a fire-control radar differs significantly from standard surveillance radars, which passively monitor airspace without direct engagement. A fire-control radar, by contrast, actively locks onto a target, feeding precise data to a weapons system for a potential strike.
This distinction elevates the March 19 incident beyond routine monitoring, positioning it as a deliberate escalation. “Such an illumination indicates hostile intent, as it’s the final step before a missile launch,” the General Staff noted in a statement.
Western analysts have suggested that the Russian warship’s actions may have been intended to deter the French aircraft from its surveillance mission, though no missile was fired, and the situation did not escalate further. The Atlantique 2, equipped for maritime patrol and anti-submarine warfare, continued its task, demonstrating operational resilience in the face of the radar lock.
This was not the first time an Atlantique 2 encountered Russian radar in the Baltic region. In January, another aircraft from the same fleet was targeted by an S-400 system stationed in Kaliningrad, a Russian enclave bordered by Poland and Lithuania. That earlier incident also took place during a NATO mission, with the aircraft monitoring international waters.
French officials at the time condemned the move as an unacceptable provocation, with Lecornu stating on social media that the “aggressive Russian action” would not deter France from defending freedom of navigation. The recurrence of these encounters suggests a deliberate Russian strategy to assert control over the Baltic Sea, a waterway critical to both NATO and Russian interests.
The January event, like the one in March, saw the Atlantique 2 complete its mission despite the radar illumination, reinforcing France’s commitment to its operational objectives.
Analysts point to several factors driving French aerial activity in the Baltic Sea and adjacent regions. The Atlantique 2’s presence aligns with NATO’s broader efforts to secure critical infrastructure, including undersea cables and pipelines, which have faced suspected sabotage in recent months.
In December, the EstLink 2 power cable between Finland and Estonia was damaged, alongside several telecommunication lines, prompting Finnish authorities to investigate possible Russian involvement.
NATO Secretary General Mark Rutte responded by announcing an increased military presence in the region, with Operation Baltic Watch serving as a direct countermeasure.
The French aircraft’s role in this mission likely involves low-altitude flights to gather detailed intelligence on maritime activity, potentially using sonobuoys—hydroacoustic devices dropped into the water to detect submarines. Such operations could explain Russia’s decision to deploy its fire-control radar, viewing the French surveillance as a challenge to its naval operations.
The geopolitical context further illuminates these tensions. Europe is grappling with heightened security concerns following Russia’s invasion of Ukraine in 2022, which has strained relations with NATO members, including France.
The Baltic Sea, often described as a “NATO lake” due to its proximity to alliance members like Sweden, Finland, Poland, and the Baltic states, remains a contested space.
Russia maintains a significant military presence in Kaliningrad, home to its Baltic Fleet and advanced air defense systems like the S-400. This enclave provides Russia with a strategic foothold, enabling it to project power and monitor NATO movements.
The French aircraft’s operations near this sensitive area may be perceived by Moscow as an encroachment, prompting responses like the radar lock to signal its disapproval.
The use of a fire-control radar carries distinct implications compared to surveillance systems. While surveillance radars sweep broad areas to track aircraft or ships, they do not typically engage specific targets.
Fire-control radars, however, are designed for precision, aligning with a weapons system to calculate a target’s speed, altitude, and trajectory. This process, known as “illumination,” prepares the system for an attack, making it a more immediate threat.
Military experts note that such actions are rare in peacetime and often serve as a warning rather than a prelude to violence. In this case, the Russian warship’s radar lock could have been a calculated move to test the French crew’s reaction or to assert dominance without crossing into open conflict.
Atlantique 2’s decision to proceed with its mission suggests a measured response, avoiding escalation while maintaining its operational mandate.
To understand the aircraft at the center of these incidents, a closer look at the Atlantique 2 is warranted. Developed by Bréguet and Dassault Aviation, this twin-engine turboprop entered service with the French Navy in the late 1980s as an evolution of the earlier Breguet Atlantic.
Designed primarily for maritime patrol and anti-submarine warfare, it boasts a flight endurance of up to 14 hours and a range of approximately 4,300 nautical miles. Its distinctive bilobed fuselage houses a pressurized cabin for the crew and a weapons bay capable of carrying torpedoes, anti-ship missiles, and sonobuoys.
The aircraft’s sensor suite is equally impressive, featuring a 360-degree Iguane radar for surface and air surveillance, a forward-looking infrared [FLIR] sensor for night operations, and a magnetic anomaly detector [MAD] to locate submerged submarines. These capabilities make the Atlantique 2 a versatile platform, well-suited for monitoring the Baltic Sea’s complex maritime environment.
Recent upgrades have further enhanced the aircraft’s effectiveness. The French Navy’s fleet of 22 Atlantique 2s has undergone modernization since 2013, with improvements to its radar, sensors, and mission management systems.
The Standard 6 configuration, set to be fully implemented this year, bolsters its anti-submarine capabilities and integrates advanced communication systems for coordination with NATO forces. During its Baltic Sea mission, the aircraft likely flew at low altitudes—possibly below 1,000 feet—to deploy sonobuoys or visually identify Russian vessels.
This proximity could have heightened Russian concerns, leading to the radar engagement. The Atlantique 2’s ability to operate in contested areas, combined with its sophisticated equipment, positions it as a key asset in France’s contribution to NATO’s regional security efforts.
France and Russia’s relationship provides additional context for these encounters. Since the onset of the Ukraine conflict, Paris has taken a firm stance against Moscow, supplying military aid to Kyiv and advocating for stronger European defenses.
President Emmanuel Macron has emphasized that supporting Ukraine’s sovereignty is essential to preventing broader Russian aggression, a position that has strained diplomatic ties. Russia, in turn, has accused NATO of encroaching on its sphere of influence, particularly in areas like the Baltic Sea and Black Sea regions.
The targeting of French aircraft may reflect Moscow’s broader frustration with a Western military presence near its borders, though it stops short of direct confrontation. French officials, including Lecornu, have reiterated their commitment to international operations, signaling that such incidents will not alter their strategic posture.
As these events unfold, the Baltic Sea remains a focal point of geopolitical friction. NATO’s increased surveillance, driven by concerns over infrastructure security, continues to intersect with Russia’s efforts to assert its regional authority.
The Atlantique 2’s encounters with Russian radar underscore the delicate balance both sides must navigate—maintaining presence and deterrence without tipping into outright conflict.
For now, the French crew’s professionalism in completing their mission amid intimidation reflects a broader resolve among NATO allies. The coming months will likely reveal whether these incidents mark a temporary spike in tensions or a more enduring shift in the region’s security landscape.
