A French Navy Mistral class amphibious assault ship has been photographed carrying Naval Group’s new Rampart modular launcher, a system designed to allow a single weapon station to employ different types of rockets, missiles, and other effectors against a wide range of threats.

The imagery, captured off Toulon during training on September 21, reveals the launcher installed on the ship’s forward starboard sponson. While the specific identity of the vessel is unclear, this represents the first publicly observed evidence that Rampart has moved into shipboard testing.

Naval Group announced in June that the first at-sea firing campaign for Rampart was planned for October aboard a Mistral class ship during the French Navy’s Wildfire counter-drone exercise.

What makes Rampart unusual is its modular architecture. Rather than being built around one missile or rocket, the system uses interchangeable launch modules that can accommodate different weapons. This allows a ship to carry large numbers of relatively inexpensive guided rockets for counter-drone work while retaining the option of using larger and more capable short-range missiles against more challenging targets.

Because the launch modules are interchangeable, the mix can theoretically be changed as the mission or threat environment changes.

The approach is aimed squarely at a problem that has become increasingly important for naval forces: defending expensive ships against potentially large numbers of inexpensive uncrewed systems and missiles without relying exclusively on high-cost interceptors.

Rampart was previously known as the Multi-purpose and Modular Launching System (MPLS). Naval Group unveiled the concept in 2023 as a self-funded development effort and formally presented the Rampart earlier this year.

The launcher uses four interchangeable ammunition modules. Depending on the configuration, Naval Group says that the system can accommodate up to 80 Thales 68mm laser-guided rockets or 48 NATO-standard 70mm laser-guided rockets. Other configurations can carry smaller numbers of short-range missiles (four to six per module, depending on type) or other effectors, including decoys.

The system has already been demonstrated with guided rockets. A January 2026 test involved a Thales 68mm guided rocket, followed by a series of firings at the Canjuers range in southern France in May. Those trials, seen in the video below, included engagements against targets at roughly two miles and a five-rocket salvo.

The relatively small guided rockets are particularly relevant to counter-drone operations. They offer a way of engaging aerial targets with a weapon substantially smaller than a conventional surface-to-air missile, while still providing precision guidance.

As well as rockets, Naval Group has been working with Thales on the Lightweight Multirole Missile (LMM). Also known as Martlet, the LMM is intended to tackle a range of challenging airborne and surface targets, as you can read about here.

The company has also explored integration of loitering munitions and other missiles, while a separate agreement with the UAE-based EDGE Group covers trials of the SkyKnight surface-to-air missile.

The company has also pursued integration of Poland’s Piorun short-range air-defense missile. This may well be with a view to a potential Polish purchase of Rampart to arm its forthcoming frigates, which you can read about here.

This means the launcher is effectively being developed as an open weapons-integration platform, rather than as a dedicated launcher for one or a small set of particular munitions.

That openness could make Rampart attractive to a wide range of navies. Instead of requiring customers to adopt a completely new missile family, the launcher can potentially be configured around weapons already in their inventories or sourced from their domestic defense industries. A country could therefore buy the common Rampart launcher while retaining control over the effectors it wants to integrate, whether those are guided rockets, short-range missiles, loitering munitions or other systems. At the same time, when it comes to air threats, this is very much a point defense system for close-in engagements, and a last line of defense to complement longer-range and more capable systems.

Naval Group has described the system as capable of operating either autonomously or as part of a ship’s combat system, with a stabilized turret and integrated fire-control equipment.

That integration will be particularly important during the upcoming sea trials. A launcher that works against stationary or land-based targets still has to contend with ship motion, vibration, sea spray, sensor integration, and the compressed timelines involved in defending a moving vessel.

France operates three Mistral class amphibious assault ships, which serve as major aviation, command, and amphibious warfare platforms. Their size and mission make them high-value assets that could face a broad range of aerial threats during operations. Another two vessels were built to the same design for Russia, before being placed under embargo, and then sold to the Egyptian Navy.

Naval Group’s choice of a Mistral for the initial at-sea campaign provides an opportunity to test Rampart under realistic operational conditions while integrating it with an existing French naval combat system.

In its basic form, each Mistral is armed with a pair of Simbad launchers, each of which is fitted with two Mistral short-range surface-to-air missiles. In terms of guns, each of the vessels is armed with two 30mm and two 20mm cannons, two 7.62mm M134 Miniguns, and four 12.7mm machine guns. Adding even a single Rampart launcher provides considerably more options against aerial targets across a wide range of threats — depending on the effectors that are included.

Recent U.S. and allied operations in the Middle East have highlighted the problem of large-scale missile and drone attacks causing forces to expend substantial numbers of interceptors, raising concerns about both magazine depth and the cost of using high-end missiles against lower-cost threats. Directed-energy weapons could eventually provide a way out of that cost-exchange problem, but shipboard laser systems remain in the early stages of operational development. Navies cannot simply wait for them to mature, creating an immediate requirement for lower-cost, high-capacity kinetic options. Rampart’s large guided-rocket capacity and ability to mix different effectors are aimed at exactly that gap.

If Rampart can reliably engage drones with inexpensive guided rockets while retaining the ability to employ more capable missiles from the same launcher, it could offer navies an additional defensive layer between conventional guns and high-end surface-to-air missile systems.

Critically, new effectors could potentially also be integrated as they become available, allowing the system to evolve without replacing the entire turret.

Reflecting the urgency of the requirement, Naval Group’s development path for Rampart has been relatively rapid.

Naval Group has also demonstrated a ground-based Rampart, mounted on a high-mobility truck chassis. This configuration is intended for mobile air defense missions as well as protection of fixed sites, giving the system a role beyond ship self-defense. The truck-mounted version could provide a rapidly relocatable launcher for counter-drone and short-range air-defense missions, while retaining the same basic modular architecture and ability to employ different effectors.

The photographs from Toulon indicate that the Rampart concept is now moving from the range to the French fleet, albeit on an experimental basis. The forthcoming sea campaign will be an important milestone and should provide a better idea of how this system works at sea.

Ukraine has unveiled a new domestically developed surface-to-air missile system designed to turn a diverse collection of air-to-air missiles into a flexible ground-based air defense capability. Called Shershen, Ukrainian for hornet, the system combines a locally-developed command-and-control architecture, a dedicated surveillance radar, and multiple launchers that can employ both Ukrainian and Western missiles.

The system was displayed at the MSPO defense exhibition in Kielce, Poland, by the National Association of Ukrainian Defense Industries (NAUDI). The example shown is reportedly the second operational prototype and is described as being close to its production configuration.

At the ongoing MSPO-2026 defense and industrial exhibition in Poland, the launcher of the Ukrainian Shershen air defense system, developed by Radionix, has been presented for the first time, along with the R-120K surface-to-air guided missile specially developed for it (second… pic.twitter.com/5RfZWHWuxl

The appearance of Shershen comes as Ukraine continues to develop an increasingly diverse family of indigenous air defense systems, while simultaneously adapting older missiles and foreign-supplied weapons to address a severe shortage of interceptors.

That effort has produced some distinctly unconventional combinations. Ukraine’s so-called FrankenSAM programs have paired existing Soviet-era launchers and radars with Western missiles, while other systems have adapted Soviet R-73 air-to-air missiles for ground launch. The United Kingdom and Denmark have also worked with Ukraine on the containerized Gravehawk system, another concept built around repurposed air-to-air missiles.

Shershen takes that philosophy a step further by making missile interchangeability a central feature of the system.

The Shershen battery consists of a Perun command-and-control vehicle, an Athena radar, and four Borei launchers.

According to the developer, the system’s architecture is deliberately open. This allows it to use different missiles from different manufacturers and also permits the integration of third-party surveillance and guidance radars.

The company says Shershen can currently employ the R-27 (AA-10 Alamo), R-73 (AA-11 Archer), AIM-9 Sidewinder, and AIM-132 ASRAAM, while compatibility with the R-60 is also being explored. These weapons come with a mix of semi-active radar or infrared homing seeker heads.

Air-to-air missiles are already available in considerable variety across Ukraine’s arsenal and those of its foreign partners. Being able to employ several types from a common ground-based system provides much more flexibility than a conventional SAM designed around one dedicated interceptor.

It also offers a way to exploit missiles that were never originally intended to be fired from the ground. That means Shershen’s launcher and fire-control system are meant to be interceptor agnostic, at least to a certain degree.

Shershen’s Athena radar is reported to be capable of detecting targets at ranges of up to 85 kilometers (53 miles).

In terms of the engagement envelope, Shershen is claimed to be capable of engaging aircraft, cruise missiles, and drones at ranges of up to 25 kilometers (16 miles) and altitudes of up to 10,000 meters (32,800 feet). Clearly, these figures will vary widely depending on the type of interceptor.

When employing radar-guided missiles, the system’s engagement architecture can reportedly guide as many as six missiles simultaneously.

The advertised performance figures have not been independently verified, and it remains unclear what target types and engagement conditions were used to establish them.

The developer says the second prototype has completed initial testing, including successful interceptions at a test range.

One of the Borei launchers displayed at MSPO were armed with an R-120K, a new Ukrainian missile equipped with a radar seeker and is intended to be capable of both air-to-air and surface-to-air employment.

The R-120K remains under development, however. Work is reportedly continuing on its rocket motor, meaning that its eventual performance and production status remain uncertain. Still, having the option of including the R-120K on the Shershen system in the future is significant.

Rather than relying indefinitely on stocks of Soviet and Western air-to-air missiles, Ukraine could eventually have a domestically produced interceptor specifically tailored to its growing family of ground-based air-defense systems. That will become increasingly important as stocks of legacy missiles are depleted. Earlier this year, it was reported that Ukrainian F-16s were running low on their air-to-air missiles, which include the same AIM-9s that are used in some FrankenSAM systems, as well as being compatible with Shershen. But even before that, it was clear that Western-supplied missile stocks in Ukraine across the board were diminishing, in some cases drastically, with critical interceptors like the AMRAAM and Patriot being badly affected.

Ukraine’s need for additional surface-to-air missiles has become increasingly acute during the full-scale war, especially as Russian drone and missile barrages have stepped up.

The shortage has encouraged Ukraine to pursue a combination of indigenous development and unconventional adaptations.

The FrankenSAM initiative, conducted with U.S. support, demonstrated how existing Ukrainian systems could be combined with foreign missiles to rapidly create additional air-defense capacity. Ukraine has also fielded modified Osa systems armed with R-73 air-to-air missiles rather than their original 9M33 interceptors. Other R-73-based concepts have even been demonstrated aboard Ukrainian uncrewed surface vessels.

Shershen appears to reflect the next logical step in that evolution: rather than creating a one-off FrankenSAM combination, build an architecture from the outset that can accept multiple missiles. Additionally, with so many different ground-based air defense systems now being fielded, it comes with the significant advantage of a standardized launcher and control interface that can accommodate a range of interceptors.

At the same time, Ukraine is pursuing substantially more ambitious indigenous SAM projects.

Earlier this year, a previously secretive Ukrainian missile identified as the Koral made what appeared to be its first public appearance. The program dates back to at least 2021, when Ukraine’s Luch design bureau presented a concept for a medium-range surface-to-air missile.

Koral is intended to provide a much longer-range capability, potentially filling some of the gap left by Ukraine’s aging Soviet systems and supplementing the Western-supplied Patriot and SAMP/T.

Shershen, by contrast, is clearly focused on the short-range layer.

Together, the programs illustrate the breadth of Ukraine’s emerging domestic air-defense effort: from relatively inexpensive systems built around repurposed air-to-air missiles to new, purpose-designed interceptors intended to replace or augment Soviet-era systems.

Ukraine’s experience with FrankenSAM has demonstrated the value of getting unconventional air defense combinations into service quickly.

Once fielded, Shershen, with its architecture capable of accepting different Soviet-origin and Western-made interceptors, and eventually a Ukrainian one, gives Ukraine another way to stretch its missile inventory and enhance its air defense capabilities.
