Can Warships Afford the Drone War? France’s Rampart Launcher Tests a Different Answer
A French amphibious assault ship has fired Naval Group's Rampart close-in weapon system at sea for the first time. The important part is not the launcher. It is the magazine behind it.
During WILDFIRE 26.2 off Toulon, the French Navy and Naval Group fired 68 mm rockets from Rampart against both surface and aerial drone-type threats. Unguided rockets engaged a remote surface target. A laser-guided Thales rocket was fired against an aerial target. A Polish Piorun very-short-range air-defense missile was also loaded into one of the launcher modules and successfully acquired the UAV with its seeker, although it was not fired.
Rampart approaches close-range defense differently from a conventional missile launcher. Four interchangeable modules can be loaded with different effectors depending on the mission: guided or unguided rockets, very-short-range missiles, surface-to-surface weapons, decoys and potentially other future payloads.
With 20 guided 68 mm rockets fitting into one module, an all-rocket configuration could theoretically place as many as 80 rounds on one mount. That creates an entirely different magazine equation from using one premium surface-to-air missile every time a small drone appears over the horizon.
The wider French and European counter-UAS market is moving in the same direction. Radar manufacturers are expanding output. Passive optical sensors are being linked with interceptors. Jammers, lasers and interceptor drones are moving alongside guns and rockets. The objective is no longer to find one perfect anti-drone weapon. It is to make sure the ship always has another affordable layer available.
France tested both sides of the drone problem
WILDFIRE 26.2 ran off Toulon from September 28 through October 2. The French Navy used the exercise to expose ships and crews to realistic aerial and surface drone threats in the maritime environment.
Six naval vessels participated, including air-defense combatants, a supply ship, a La Fayette-class frigate and, for the first time in the exercise series, a Mistral-class amphibious assault ship carrying Rampart.
Unguided rockets
A salvo of Thales unguided rockets was fired against a remotely controlled surface target.
Guided rocket
A laser-guided Thales rocket was fired against a target UAV to assess the counter-UAS engagement chain.
Piorun
The Polish VSHORAD missile was not fired, but its seeker was activated and acquired the drone target.
The trial therefore tested more than one ammunition type and more than one threat domain. That matters because the close-range problem around a ship increasingly includes small aerial drones, uncrewed surface craft, fast boats and potentially several threats arriving together.
Four modules turn one mount into several weapon systems
Naval Group first presented the system publicly as the Multi-Purpose and Modular Launching System. It has since been named Rampart.
The basic architecture is a fast-moving two-axis turret carrying four interchangeable ammunition modules. Naval Group describes each module as roughly 60 centimetres wide and two metres long.
Illustrative all-rocket configuration
Maximum 80-round illustration assumes all four modules are devoted to the 68 mm rocket configuration. Operational loadouts may instead mix rockets, missiles, decoys or other effectors.
The important feature is not that a ship must carry 80 rockets. It is that the same physical launcher can be reconfigured.
A deployment through a high-drone-threat region might favor a deep rocket magazine. Another mission could trade one or more rocket modules for very-short-range missiles or decoys.
The launcher can operate as a standalone system or integrate with the ship's combat management system and fire-control architecture.
The interceptor cannot cost more than the defense can sustain
The tactical problem created by drones is not simply whether a ship can destroy one incoming UAV. Modern warships already carry weapons capable of doing that.
The difficult question is whether the ship can continue doing it after the fifth, tenth or twentieth target.
One mount, very different magazine logic
That trade is fundamental.
A longer-range missile gives the ship more reaction time, greater reach and potentially more opportunities to re-engage a target. A short-range rocket creates a denser magazine but waits until the threat is much closer.
The optimal defense therefore does not choose one or the other. It attempts to assign the cheapest effective layer to each threat while preserving enough higher-end weapons for targets that cannot safely be allowed into the close-in envelope.
Rampart matters only if the ship detects the drone early enough
Small UAVs stress the beginning of that chain as much as the end. Their radar cross-sections can be small, their flight paths irregular and their altitude extremely low.
A ship cannot exploit an 80-round close-range magazine if the system identifies the attack only seconds before impact.
The anti-drone production surge begins with radar
The counter-UAS market is driving demand for smaller radars that can detect and provide fire-control-quality tracks on targets that conventional air-defense systems were not necessarily optimized to prioritize.
A new $40 million U.S. production facility is designed to lift annual radar-panel capacity to approximately 30,000 units. The company says counter-drone demand caused it to pull its planned 2027 expansion into 2026.
Thales and the Netherlands Ministry of Defence are expanding radar production and test capacity at Hengelo, including new production facilities, electronics capacity and a new test tower.
Thales reports more than 85 GM200 radars sold. The system can track drones alongside aircraft, missiles and surface targets.
The companies are combining passive infrared surveillance and counter-UAS technologies after large-scale field trials, adding a sensor path that does not depend on continuous radar transmission.
Not all of those systems are naval products, but the production trend matters to navies because the underlying problem is shared: mass drone threats require far more distributed sensors than traditional air-defense architectures were built around.
The cheapest successful engagement is the one that uses no projectile
French naval-defense work increasingly treats electronic warfare, directed energy and kinetic weapons as complementary rather than competing answers.
Naval Group's current near-field-defense concept explicitly allows jamming and other non-lethal measures to sit inside the same close-protection architecture as offensive effectors such as missiles and Rampart.
| Layer | Representative technology | Magazine effect | Main constraint |
|---|---|---|---|
| Electronic attack | RF jamming / cyber-RF effectors | Potentially repeated engagements without expending physical ammunition | Autonomous drones may continue operating if navigation and targeting do not depend on vulnerable links. |
| Laser | HELMA-P / future SYDERAL | Deep theoretical magazine while electrical power remains available | Weather, atmospheric conditions, dwell time and line-of-sight affect performance. |
| Interceptor drone | Systems such as Blaze | Adds another relatively scalable physical layer | Still consumes an interceptor and requires its own detection and control chain. |
| Gun | 76 mm or smaller naval artillery | Substantially deeper ammunition supply than major missiles | Probability of kill, engagement geometry and minimum range become increasingly important. |
| Guided rocket | Rampart 68 / 70 mm family | Potentially dozens of rounds from one compact launcher | Shorter engagement envelope than major surface-to-air missiles. |
| VSHORAD | Piorun / future compatible missiles | Higher-performance close-range layer | Smaller magazine and higher-value interceptor than rockets. |
| Area-defense missile | Aster family | Long-range interception and greater engagement opportunity | Finite vertical-launch magazine must also support higher-end threats. |
Rampart is arriving beside directed-energy development, not instead of it
The French Navy tested the HELMA-P laser at sea aboard the air-defense frigate Forbin in June 2023 after earlier land-based trials.
The system was developed to track and physically damage hostile drones with concentrated laser energy and can be integrated aboard ships.
France has since moved toward a more powerful follow-on.
In August 2025, the DGA ordered the SYDERAL high-power laser demonstrator from a consortium involving MBDA, Safran Electronics & Defense, Thales and CILAS. The programme is intended to demonstrate a weapon in the tens-of-kilowatts class against tactical drones, rockets, mortar rounds and remotely operated munitions, with a target of providing the armed forces a future capability around 2030.
France is also pushing existing naval weapons deeper into the counter-drone mission
In April 2026, the FREMM Normandie used its 76 mm gun and upgraded STIR fire-control system against two ALBA aerial targets representing low-flying drones.
The targets flew at approximately 80 knots. The Navy reported that both were destroyed despite dense fog reducing visibility to less than 200 metres.
That test reinforces the layered approach.
The future close-defense magazine is not one magazine
A French warship may ultimately have electronic attack, guns, guided rockets, very-short-range missiles, area-defense missiles and directed energy available against different stages of the same attack.
The combat-management problem becomes deciding which layer should engage each target and when the ship should escalate to the next one.
The rocket is becoming a cross-platform anti-drone weapon
Rampart is not the only French programme using 68 mm guided rockets against UAVs.
In July 2026, the DGA completed integration testing of laser-guided 68 mm rockets on Rafale fighters for counter-drone missions. France said fewer than eight months separated contracting from the first operational capability.
The test sequence used the Rafale radar to detect the target, the Talios pod to track and designate it, and the guided rocket to complete the engagement.
The French Air and Space Force described the capability as suitable for threats including Shahed-type drones.
A deep launcher matters only if industry can keep filling it
A ship carrying 80 rounds has little value if wartime consumption quickly exceeds manufacturing capacity.
Thales Belgium says it has been expanding its family of 70 mm guided, unguided and counter-drone rockets while increasing production capacity in response to demand.
That company is already working with Naval Group on Rampart. Further testing using Belgian 70 mm rockets is planned for 2027.
The distinction between a 68 mm French-standard rocket family and a 70 mm NATO-standard family is particularly important to Rampart's export strategy. A modular launcher that can accept ammunition from several suppliers reduces the chance that the complete weapon system becomes tied to one national production line.
Naval Group has also previously announced integration work involving Thales Lightweight Multirole Missile, MBDA Mistral and Akeron families and other payloads.
The strategic feature is therefore not any single interceptor. It is the possibility that the launcher remains useful while ammunition changes faster than the ship itself.
Eighty rockets still do not guarantee survival against eighty drones
A nominal magazine count can exaggerate real defensive depth.
More than one shot may be required
If doctrine requires two interceptors per target or the probability of kill is below one, an 80-round magazine can disappear much faster than the target count suggests.
Threats can arrive simultaneously
Magazine depth does not equal engagement capacity. Fire-control channels, laser designation, launcher slew rate and target geometry determine how many threats can be serviced in the available seconds.
Not every target belongs inside the rocket envelope
A fast, maneuvering or particularly dangerous threat may justify an earlier missile engagement rather than allowing it to approach the close-defense layer.
Surface and air threats can compete for the same launcher
Rampart's strength is multi-domain flexibility. That also means ammunition consumed against fast boats is no longer available for UAVs until the modules are reloaded.
Reloading remains a tactical question
Naval Group designed the modules for comparatively simple reconfiguration and reload, including at sea, but a ship under continuous attack may not have the time or deck conditions required to safely replenish the mount.
Rampart is becoming an ammunition marketplace
The first sea firing is not the end of development.
| Effector | Origin | Status | Why it matters |
|---|---|---|---|
| 68 mm guided rocket | Thales / France | Fired against UAV at sea | Demonstrates the high-capacity counter-UAS configuration. |
| 68 mm unguided rocket | Thales / France | Fired against surface target | Provides another response for inexpensive small surface threats. |
| Piorun | Poland | Integrated; seeker locked UAV during sea trial | Adds a higher-performance VSHORAD option without dedicating the entire mount to missiles. |
| 70 mm rocket | Thales Belgium | Future Belgian trials planned | Expands compatibility toward a widely used NATO-standard rocket calibre. |
| SkyKnight | EDGE / UAE | Future UAE trial planned | Demonstrates the export philosophy of integrating customer-selected missile families. |
| Mistral / Akeron | MBDA | Integration work previously announced | Could further broaden air and surface-defense options. |
The defense has to become mass-producible too
The drone revolution creates a production imbalance if only the attacker benefits from inexpensive mass.
Echodyne's decision to build capacity for as many as 30,000 radar panels annually is one indication of how rapidly the detection side is scaling.
France has ordered Blaze interceptor drones with plans for local assembly and manufacturing. Thales and Renault are preparing production of Toutatis loitering munitions at a potential 1,000-unit monthly rate. France is investing in higher-power lasers. Thales is expanding European radar infrastructure. Passive-sensor suppliers are combining their systems with counter-UAS effectors.
Not all of those products will be installed on ships. Together they reveal the industrial direction of travel.
Mass has to meet mass
A navy cannot solve a thousand-drone production problem with a defensive industrial base capable of manufacturing only dozens of interceptors.
The requirement is therefore shifting from exquisite anti-air capability alone toward a layered system whose sensors and lower-cost effectors can themselves be produced in quantity.
The launcher fills the space between electronic warfare and the main missile magazine
| Threat condition | Preferred first layer | Possible escalation | Magazine logic |
|---|---|---|---|
| Drone dependent on RF control link | Electronic attack | Gun / rocket if jamming fails | Avoid physical ammunition if the threat can be defeated electronically. |
| Slow isolated UAV | Gun, laser or guided rocket | VSHORAD missile | Preserve area-defense missiles for more demanding threats. |
| Large autonomous UAV | Longer-range interception if identified early | Rampart / CIWS as leakage layer | Do not allow a dangerous target into minimum-range territory solely to save a missile. |
| Small surface drone | Gun or unguided / guided rocket | Heavier surface weapon | Use a proportional effector rather than a major anti-ship weapon. |
| Mixed swarm | All available layers | Prioritized engagements by threat | Distribute kills across several effectors to avoid exhausting one magazine. |
Naval Drone-Swarm Magazine Stress Test
This model tests the value of layered defense rather than assuming every drone must be destroyed with a rocket. Adjust the size of the incoming raid, soft-kill effectiveness, gun or laser contribution, rocket magazine and rocket effectiveness to see how quickly threats can leak into the missile layer.
