Germany is putting in place a formal framework that will give its defense companies extensive access to real-world combat data from German-made weapons used in Ukraine. This arrangement is part of a broad €4 billion ($4.72 billion) defense package finalized in Berlin on Tuesday.
According to Ukrainian Defense Minister Mykhailo Fedorov, the data-sharing agreement is the first of its kind for Ukraine. It includes operational insights from systems such as the PzH 2000 self-propelled howitzer, the RCH 155 wheeled artillery unit, and the IRIS-T air defense system. In exchange, Ukraine will grant Germany access to its live DELTA battlefield management system and other digital tools to support the development of AI-driven models and advanced analytics.
This agreement formalizes a process that had previously been informal. German defense manufacturers have already been using battlefield feedback from Ukraine to refine future upgrades. For instance, the PzH 2000 experienced accelerated barrel wear due to Ukraine’s higher firing rates compared to NATO standards, offering valuable lessons. Similarly, insights from the conflict contributed to integrating the Israeli Trophy active protection system into the Leopard 2A8.
In return, Germany will maintain its role as a leading supporter of Ukraine, as emphasized by Chancellor Friedrich Merz. The country is funding a deal between Ukraine and Raytheon for hundreds of Patriot PAC-2 interceptors, along with another agreement with Diehl Defence for 36 additional IRIS-T launchers. An extra €300 million ($354 million) has been allocated to enhance Ukraine’s long-range strike capabilities, including the joint production of 5,000 AI-enabled mid-range drones under the “Build with Ukraine” initiative.
The IRIS-T system has proven particularly effective, with Ukrainian forces reporting an interception success rate of around 99% in operational zones and more than 250 confirmed targets neutralized. Ukraine has also independently ordered 18 more launchers.
In effect, German defense firms are leveraging Ukraine’s wartime experience to shape next-generation military systems, partially funded by German taxpayers. President Volodymyr Zelenskyy expressed optimism that Ukraine’s battlefield expertise would become part of Europe’s broader security framework, while Merz described the arrangement as mutually beneficial.
The deal reflects a broader shift in Western support for Ukraine toward more reciprocal arrangements. While earlier aid efforts were largely driven by the goal of resisting Russia and signaling unity, recent assistance has taken on a more pragmatic, exchange-based approach.
Notably, the Taurus cruise missile was not included in the latest package, with Merz again rejecting its delivery. He argued that Ukraine’s existing capabilities make it unnecessary, a stance that appears somewhat at odds with the substantial funding allocated for long-range strike development within the same agreement.
