23 Jul 25. Having made its mark in the micromechanics industry with its silicon-core micromotor, awarded a Best of Innovation Award at CES in Las Vegas, the French deeptech SilMach has taken a new step forward with its shock microsensors. The French Defence Procurement Agency (Commissariat des Armées) has chosen SilMach’s technology to monitor personal protective equipment such as ballistic plates inserted in bulletproof vests. The French Armed Forces may now monitor its protective equipment in real-time, allowing unrivalled tracking performance and reliability As part of this program, christened GMOS, SilMach has been awarded a contract worth a minimum of €3 m, for the delivery of hundreds of thousands of microsensors over the next seven years. The first deliveries will start September 2025. The French Defence Procurement Agency (Commissariat des Armées) has chosen Silmach for its GMOS programme, which aims to equip ballistic plates with a self-monitoring system. This initial award represents a 7-year commitment. SilMach shall begin production this autumn, at its base in Besançon (eastern France), with the first deliveries expected in September 2025. Pierre-François Louvigné, CEO of SilMach, commented: “We are very proud to see our technologies being put at the service of our armed forces. The shock detectors installed on ballistic protection plates are designed, first and foremost, to protect our soldiers. In a glance, users can assess if a plate’s integrity has been compromised, be it through use or an awkward fall. Thus, by making it easier to identify potentially damaged plates, we are reinforcing personnel safety and improving operational maintenance carried out by the Service du Commissariat des Armées.” Soldiers deployed in combat zones are issued essential bulletproof protection, consisting of hard ceramic and multi-layer composite plates. However, the intrinsic fragility of ceramic raises the risk of cracking in the event of an accidental fall, compromising the level of protection. With SilMach’s ChronoMEMS® technology, each ballistic plate now contains an ultra-miniaturised, autonomous, energy-free sensor capable of detecting and logging the impact sustained. Through an integrated visual indicator, armed forces can instantly check the integrity of bulletproof protection, ensuring optimum safety for soldiers and reduced maintenance costs.
A unique shock sensor with numerous uses
The ChronoMEMS® solution forms the core of a smart and sustainable monitoring approach, enabling precise processing of shock and vibration data.
Among its numerous advantages:
- No need for a power source: Operates without an external power source.
- Reliable and accurate: Drift-resistant technology guarantees accurate measurement.
- Robust: Operational underwater, in space, and not affected by extreme conditions (temperature, pressure, electromagnetic fields).
- Compact and lightweight: The size and weight of a credit card chip.
- Easy tracking: Visual indicator displays information directly.
- Cost-effective: Costs just a few euros per sensor.
A Strategic Impact on Security and Defence
For the Armed Forces, the integration of SilMach’s technology into bulletproof protection addresses a crucial need: Real-time monitoring of protective equipment ensures traceability and reliability, boosting soldiers’ confidence in their equipment.
Pierre-François Louvigné adds: “We realised that shock detection is a common problem affecting a wide range of fields, from aeronautics to consumer goods (helmets, smartphones, computers, etc.) and the logistics of high value-added products. Thanks to the expertise we have developed, with the support of the Direction Générale pour l’Armement (DGA) and the Commissariat des Armées (SCA), we are actively exploring other use cases. Discreet, accurate and reliable, these shock detectors constantly monitor the object on which they are installed, 24 hours a day, 7 days a week. This reassures owners, manufacturers and users alike!”.
A true pioneer in technological innovation, SilMach is ushering in a new era in the monitoring of strategic equipment. The scaling of the technology’s production is already attracting interest in various sectors, including defence, security and critical infrastructures.
23 Jul 25. CSG Acquires Majority Stake in Arms Manufacturer ZVI Vsetin, a Traditional Czech Producer of Medium-Caliber Ammunition. MSM Group, the Slovak subsidiary of the industrial group CSG, has signed a purchase agreement with the MPI Group to acquire ZVI a.s., a Czech manufacturer primarily focused on medium-caliber ammunition in 20mm and 30mm calibers. The transaction price was not disclosed, as per mutual agreement between the parties.
“ZVI Vsetín is an important and traditional player in the Czech defense industry, and its know-how in ammunition, weapon, and cannon production holds strategic value for the CSG group. While this acquisition is relatively small in size, it is both symbolically and practically very significant – we are decisively expanding our capacity for ammunition and weapons systems production directly on Czech soil,” said Jan Marinov, Head of the CSG Defence Division.
In addition to its 20mm ammunition, used for example by the Czech Air Force, ZVI is the only Czech producer of 30mm ammunition certified for MK44 Bushmaster II cannons. These cannons are used by many armed forces worldwide, including the Czech Armed Forces, particularly in the Pandur 8×8 armored vehicles. This type of ammunition will also be used in the newly procured CV-90 infantry fighting vehicles for the Czech Army. ZVI is also a qualified supplier for several foreign militaries. The company’s production capacity for medium-caliber ammunition is in the high hundreds of thousands of units per year. With this acquisition, CSG expands its portfolio to include medium-caliber ammunition, which it plans to supply to the Czech Army and Air Force, as well as export abroad.
Jaroslav Král, CEO of ZVI, commented on the transaction: “CSG’s entry is a logical step in the further development of ZVI. With this partnership, the company gains not only a strong investor but above all a partner with significant export capabilities and extensive experience in growing defense-sector businesses. Furthermore, CSG will enhance ZVI’s supply chain by providing selected components – particularly energetic materials – that ZVI previously sourced from third parties. We are confident that this partnership marks the beginning of a new era of substantial growth for ZVI.”
CSG plans to invest in extensive modernization and expansion of ZVI’s production, primarily in anticipation of increased demand. Another priority is integrating ZVI into CSG’s export projects and embedding it further into the global defense industry supply chains. ZVI will become part of the CSG Defence Division. CSG also plans to invest in the development of new ammunition products in additional calibers and to place this production within ZVI’s facilities. This will result in a significant expansion of manufacturing capabilities within the Czech Republic. (Source: ASD Network)

Officials during the signing of the partnership. Credit: D&M Holding Company. D&M Holding has reached an agreement with the Ukrainian Defense Industry (UDI) to establish a joint venture (JV) to produce ammunition propellant in the US. This new US-based entity will focus on manufacturing specialty chemicals required for ammunition production, serving the Ukrainian Defense Forces’ needs. This initiative aims to alleviate the shortfall of specialty chemicals, which the “ammunition industry is currently experiencing”, said Ukraine’s largest arms producer UDI. Ukrainian Defense Industry director general Oleh Huliak said: “We have to gradually move from large-scale procurement to our own production to meet our immediate needs. It is equally important that the company will operate in a safe area. Our cooperation with American arms companies will continue in other areas.” The formalisation of JV took place at the Ukraine Recovery Conference in Rome. The new facility will produce single base propellant intended for artillery ammunition such as 155mm shells, which are currently in high demand by Ukraine for its ongoing conflict with Russia.
“This joint venture continues to build upon and further strengthen the relationship between D&M and Ukrainian state-owned enterprises with projects now in both Ukraine and the US,” D&M CEO Daniel Powers said.
Since February 2022, Ukraine has been substantially dependent on international military support for its defence against Russia.
According to the State Department’s Bureau of Political-Military Affairs Factsheet, as of 12 March 2025, the US has provided Ukraine with $66.9bn in military assistance following Russia’s full-scale incursion on 24 February 2022 and approximately $69.7bn since Russia’s initial invasion of Ukraine in 2014. In April 2025, the US Army opened a new artillery projectile loading facility. Located in Camden, Arkansas, the facility features two load, assemble, and pack lines that will produce completed high-explosive projectiles at a rate of 50,000 per month when fully operational.
