French Navy Tests Advanced L22 Data Link During Indo-Pacific Mission

The French Navy is pushing the boundaries of modern naval warfare by testing the new L22 tactical data link (TDL) during its Carrier Strike Group (CSG) deployment in the Indo-Pacific. This upgrade, replacing the older L11 system, marks a significant leap in enhancing operational efficiency and real-time battlefield awareness.

Since setting sail from Toulon on November 28, 2024, as part of the CLEMENCEAU 25 mission, the French Carrier Strike Group, led by the aircraft carrier Charles de Gaulle, has been integrating L22 into its aerial and maritime operations. This next-generation TDL, operating alongside the widely used L16, allows seamless sharing of tactical data across an entire operational zone, improving coordination between warships, aircraft, and command centers.

Lieutenant-Commander Jérémie, head of the TDL cell within the French aeromaritime rapid reaction force, highlighted the significance of the technology: “Highly secure and based on constantly evolving technology, L22 significantly increases our ability to understand and control a tactical situation. It facilitates decision-making by providing a shared vision between different levels of command.”

The first operational tests of L22 began aboard NH90 ‘Caiman’ helicopters deployed on the Charles de Gaulle and the escorting frigates. These trials were supported by combat system experts, the TDL unit of the embarked staff, and specialized teams from the naval aviation practical experimentation and reception center (CEPA/10S) in Toulon.

The CSG’s deployment has provided ample opportunities to stress-test the system in real-world conditions. In January, during the multinational exercise LA PEROUSE 25 off Indonesia, L22 was instrumental in synchronizing operations among allied forces. The testing intensified in February with the trilateral exercise PACIFIC STELLER, where French, Japanese, and American vessels successfully validated situational awareness sharing via L22. Notably, for the first time, the French Navy established a direct connection with the U.S. 7th Fleet, expanding its interoperability beyond its prior collaborations with the U.S. 6th Fleet in the Mediterranean and the 5th Fleet in the Indian Ocean.

With L22, the French Navy strengthens its ability to operate alongside key allies such as the United States, Italy, and Canada. This capability ensures comprehensive control over vast maritime zones and reinforces France’s autonomous situational awareness—an invaluable asset in today’s increasingly complex geopolitical landscape.
