CSG lands NATO fuze contracts as Europe races to rearm

CSG, the Dutch-headquartered, Prague-managed defence industrial group, has secured two long-term contracts — collectively valued in the high tens of millions of euros — to supply mechanical and electronic fuzes for large-calibre ammunition to customers in two NATO member states. The deal is notable not only for its size but for the industrial architecture it triggers: a new joint venture, Fuchs Electronics Europe, established between CSG and Reunert, the JSE-listed South African conglomerate whose subsidiary Fuchs Electronics has manufactured electronic fuzes for more than six decades.

Production will be based at ZVS holding's site in Dubnica nad Váhom, Slovakia. Deliveries under the contracts are set to begin this year, with the joint venture operating as an independent fuze supplier — meaning it will sell to other European ammunition producers as well as CSG's own group companies.

The strategic logic of vertical integration

The fuze is not a glamorous component, but it is arguably the most consequential one in a modern artillery shell: it governs when and how detonation is initiated, determining whether a round achieves impact detonation, airburst at a defined altitude, or delayed penetration. Modern 155mm electronic fuzes — the NATO-standard calibre that has dominated consumption in the Ukraine conflict — must also interface with digital fire-control systems, making them as much a precision-electronics product as a mechanical one.

That complexity is precisely why the European supply chain has struggled to scale. According to CSG chief executive of the Defence Systems division Jan Marinov, "Today, the European defence industry needs to increase capacity not only in ammunition production itself, but also in the production of its most important components." The joint venture is explicitly designed to address that chokepoint, bringing Fuchs Electronics' core fuze technology into a European regulatory and licensing environment that CSG understands well. CSG already reported revenues of €6.7 billion in 2025 and operates across nine countries, giving it the industrial footprint to scale production rapidly once the venture clears its remaining regulatory conditions.

Convergence of capital, geopolitics and defence-industrial policy

The Fuchs Electronics Europe arrangement is a textbook example of the post-2022 European defence-industrial logic: friend-shoring critical components, vertically integrating to reduce single-country dependencies, and using regulated joint ventures rather than acquisitions to navigate export-licensing constraints across multiple jurisdictions. That South Africa — a non-NATO, non-EU country with a historically export-focused defence electronics industry — is the technology anchor for a Slovak production facility underscores how pragmatically European primes are now scouring the global supply chain for sovereign-capable partners with proven IP.

For investors tracking cross-sector capital flows, the deal sits at the intersection of two major macro themes. The first is the re-armament of European NATO members: European defence budgets have risen sharply since 2022, and the bottleneck has shifted from platforms to consumables — artillery shells and, critically, the components inside them. The second is the industrial-policy race to onshore critical defence-technology manufacturing within the EU, a drive that parallels, in defence terms, what the CHIPS Act attempted to do for semiconductors. Slovakia, already home to significant automotive and defence manufacturing, is emerging as a production hub for exactly this kind of dual-use precision engineering.

The broader capital landscape is moving in the same direction. European defence-focused private equity and sovereign funds have accelerated commitments to ammunition-adjacent supply chains since 2023, and Euronext-listed primes — CSG trades under the ticker CSG on Euronext Amsterdam — are increasingly valued on their ability to demonstrate vertical integration and domestic content, not just platform sales. The Fuchs Electronics Europe joint venture, once operational, gives CSG a defensible position in one of the hardest-to-replicate segments of the artillery supply chain, with a ready customer base across European NATO producers who face the same fuze shortage CSG is now moving to solve.
