Key Takeaways

• Germany has committed €750 million for 200 Zetros-based Bohdana howitzers, now named “Marta,” featuring an L39 barrel.
• The Bohdana is a Ukrainian-developed self-propelled artillery system designed for NATO standards, which has shown effectiveness in combat.
• The Zetros chassis enhances logistical compatibility with German military support and established NATO supply chains.

Description of the Partnership and Project

At Eurosatory 2026, a representative from Ukrainian Armoured Vehicles confirmed that Germany’s order of 200 Bohdana howitzers will be built on a Mercedes-Benz Zetros chassis. The systems have been designated “Marta” and will feature an L39 barrel, aligning with a previous defense agreement between Ukraine and Germany worth approximately €750 million ($870 million) made in December 2025.

The Bohdana artillery system is a self-propelled 155mm weapon that has shown promise in various combat scenarios, including notable engagements on Snake Island in 2022. The new production batch, utilizing the Zetros chassis, reflects both Ukraine’s advanced defense manufacturing capabilities and its ongoing effort to meet NATO standards. This integration is presented as crucial given the current military context.

The choice of the Zetros chassis is strategic, ensuring that the howitzers can leverage established logistics structures of German military support. The Zetros is extensively used by European armed forces, making maintenance and supply smoother, particularly beneficial for Ukraine as it continues to produce and deploy these systems under active wartime conditions.

The L39 barrel length, measuring approximately 6 meters, provides a different performance profile compared to L52 barrels used in more advanced Western howitzers. While it does not compromise operational requirements, this configuration favors rate of fire, mobility, and rapid repositioning, which are essential in Ukraine’s counter-battery tactics. However, specific data regarding range and muzzle velocity with NATO-standard 155mm ammunition has not been disclosed.

Current production figures for the Bohdana stand at about 40 units per month, a pace established as of October 2025. This indicates a sustained industrial effort by Ukraine to manufacture complex military systems despite ongoing conflict. If this rate continues, the timeline for Russia’s order could align with Ukraine’s production capacity, merging several Bohdana variants in operational use.

As Ukraine continues to innovate in defense production, the Zetros-based Marta signifies a substantial step toward strengthening its industrial base, bolstered by substantial German funding. This project showcases the evolution of Ukraine’s defense capabilities and its increasing integration into NATO’s logistics and support infrastructure, merging indigenous design with European industrial support.
