Naval Group made waves at Euronaval 2024 with the debut of its latest uncrewed surface vehicle (USV), the SeaQuest-S. This compact, high-performance craft, measuring just 9.3 meters in length, is a testament to Naval Group’s innovative approach to maritime security and uncrewed technologies.
Equipped with modular systems and a robust sensor suite, SeaQuest-S is designed to enhance naval deterrence, intelligence gathering, and combat support capabilities, making it suitable for both governmental and civilian applications, according to Aude Leroy.
A defining feature of the SeaQuest-S is its advanced 4-meter Panoramic Sensor Integrated Module (PSIM). This mast, which can fold down for stowage, consolidates navigation, security sensors, and command systems within a single, efficient unit.
The SeaQuest-S comprises three primary modules, each designed for specific functionalities and customizability. The front section is built to house a swarm of drones, additional fuel, or, if needed, weaponry. Although the Naval Group hasn’t confirmed the SeaQuest-S as armed, the platform’s design makes it “combat-ready,” according to Pierre-Antoine Fliche, from the Naval Group’s Drones, Autonomous Systems, and Submarine Weapons (DSA) Department. The rear compartment is dedicated to communications, but all internal configurations can be customized according to the operator’s needs.
Designed to integrate seamlessly with a variety of vessels, the SeaQuest-S can be stowed on front-line ships, such as frigates, logistic support ships, transport vessels, and minesweepers. This flexibility is crucial for rapid deployment, as no modifications to the ship’s structure or lifting systems are needed. Once deployed, either from a ship or a shore installation, the SeaQuest-S can operate autonomously or in a coordinated swarm, even in challenging conditions up to sea state 5.
Powered by a 350-horsepower diesel inboard motor with waterjet propulsion, the SeaQuest-S combines speed and maneuverability, reaching up to 35 knots. It can operate for about five hours per mission, with a range extending over 200 nautical miles, making it ideal for securing sensitive areas or acting as an advanced remote sensor for larger naval vessels. Its primary defense mechanism lies in its speed and evasive capabilities, allowing it to swiftly disengage from threats if necessary.
The first production unit, launched in July 2024, has already demonstrated Naval Group’s commitment to pushing boundaries in naval technology and modular, unmanned systems.
