OHB SE Fully Acquires MT Aerospace Strengthening Ariane 6 Role

OHB SE Solidifies Its Stake in European Space and Defense by Fully Acquiring MT Aerospace

In a strategic move that underscores a long-term vision for Europe’s space and defense sectors, technology group OHB SE has completed the full takeover of MT Aerospace AG. By acquiring the remaining 30% of shares, OHB SE transitioned from a majority stakeholder to the sole owner of the Augsburg-based Aerospace specialist. This transaction, finalized on October 29, 2025, marks the culmination of a partnership that began two decades ago and signals a reinforced commitment to the burgeoning global launch vehicle and defense markets.

The significance of this Acquisitions extends beyond corporate consolidation. MT Aerospace is a cornerstone of Europe’s independent access to space, serving as the largest German supplier to the Ariane 6 program. As the continent’s next-generation launch vehicle, Ariane 6 is pivotal for deploying critical infrastructure, from navigation and Earth observation satellites to national security payloads. This full integration allows OHB to streamline operations and align strategies more closely, ensuring robust support for Europe’s strategic autonomy in an increasingly competitive and contested domain. The move is a calculated step to harness the synergies between the two entities, positioning the unified group to better navigate and capitalize on future opportunities.

For OHB, this is more than just a financial transaction; it is a declaration of confidence in the trajectory of both MT Aerospace and the wider market. The decision reflects a belief in the sustained growth of the commercial launch industry and the increasing importance of a strong, integrated defense industrial base in Europe. By bringing MT Aerospace entirely under its umbrella, OHB is better equipped to pursue a cohesive Strategy across its Space Systems, Aerospace, and Digital segments, leveraging MT Aerospace’s specialized Manufacturing capabilities to enhance its offerings and solidify its market position.

A Partnership Culminates: The Path to Sole Ownership

The relationship between OHB and MT Aerospace is a story of strategic evolution that dates back to 2005. It was then that OHB Technology AG, as it was known, joined forces with the private equity firm Apollo Capital Partners to acquire MAN Neue Technologie. This joint venture was a foundational moment, leading to the formation of MT Aerospace in Augsburg and MT Mechatronics in Mainz. For OHB, this was a strategic entry into the launcher business, securing a significant workshare in the Ariane 5 program and laying the groundwork for a deeper involvement in European space transportation.

Over the next two decades, MT Aerospace operated as an integral part of the OHB Group, contributing its expertise in lightweight metallic and composite structures to a variety of high-profile projects. The company established itself as a leader in producing essential components for launch vehicles, aircraft, and satellites. The partnership with Apollo Capital Partners provided a stable framework for growth, allowing MT Aerospace to flourish while benefiting from the strategic oversight and market access of the OHB Group.

The decision by OHB SE to acquire the final 30% stake from Apollo Capital Partners represents the logical conclusion of this long-standing collaboration. It transforms a successful partnership into a fully integrated corporate structure. This move is driven by a conviction that complete ownership will unlock new efficiencies and strategic advantages, particularly in the rapidly expanding defense sector. As Marco Fuchs, CEO of OHB SE, noted, being the single shareholder will make it easier to strengthen the company’s position in this critical market.

“The full takeover of shares in MT Aerospace AG underlines both our confidence in the company’s established growth path and in the very positive development of the global launch vehicle market.”, Marco Fuchs, CEO of OHB SE

Strengthening Europe’s Launch Capabilities

At the heart of this acquisition lies the Ariane 6 program, Europe’s flagship initiative to guarantee its independent access to space. MT Aerospace is not just a supplier; it is a linchpin in the Ariane 6 production chain. The company holds a workshare of over 10%, making it the largest German contributor to the program. Its responsibilities include manufacturing key structural components, such as tank domes and metallic structures for the rocket’s boosters and upper stage. The reliability and quality of these components are mission-critical, directly impacting the performance and success of every launch.

The full integration of MT Aerospace into OHB SE ensures a more streamlined and resilient Supply-Chain for Ariane 6. In an era of geopolitical uncertainty and supply chain disruptions, having a tightly integrated industrial base is a significant strategic asset. This consolidation allows for better long-term planning, investment in advanced manufacturing technologies, and a more agile response to evolving program requirements. It solidifies Germany’s industrial contribution to the Ariane program and, by extension, reinforces Europe’s collective capacity to place its own assets in orbit without relying on foreign partners.

Beyond Ariane 6, MT Aerospace’s expertise has broader applications. The company’s capabilities in lightweight structures and advanced materials are relevant for future launch systems, satellite buses, and even deep-space exploration missions. With over 500 employees dedicated to developing and manufacturing these high-performance components, the company represents a significant pool of specialized talent and industrial know-how. Bringing this expertise fully in-house allows OHB to leverage these skills across its entire portfolio, fostering innovation and enhancing its competitive edge in both institutional and commercial markets.

Strategic Implications for the Defense and Aerospace Markets

The takeover is explicitly framed by OHB’s leadership as a strategic move to bolster its position in the defense market. This aligns with a broader European trend of increased defense spending and a renewed focus on sovereign capabilities. MT Aerospace has long been a partner to the defense industry, providing specialized components and manufacturing services. As a wholly-owned subsidiary, its activities can be more closely aligned with OHB’s overarching defense strategy, creating a more powerful and integrated offering for government customers.

Vertical integration, where a company controls multiple stages of the production and supply chain, is a proven strategy for enhancing efficiency and competitiveness in the aerospace and defense sectors. By becoming the sole shareholder of MT Aerospace, OHB gains greater control over a critical part of its supply chain, reducing dependencies and potentially lowering costs. This structure enables the group to offer more comprehensive, end-to-end solutions, from satellite design and manufacturing (Space Systems) to launch vehicle components (Aerospace) and data services (Digital).

This consolidation also positions the OHB Group to better compete on the global stage. The international space economy is dynamic and fiercely competitive, with new players and technologies constantly emerging. A larger, more integrated entity like the expanded OHB Group is better able to invest in research and development, scale production, and pursue large-scale, complex Contracts. The move sends a clear signal to the market that OHB is committed to long-term growth and is positioning itself to be a leading European prime contractor in both the space and defense arenas.

Conclusion: A Unified Front for a New Era in Space

OHB SE’s full acquisition of MT Aerospace AG is a defining moment that consolidates two decades of partnership into a unified corporate entity. This strategic integration is about more than just corporate structure; it is a forward-looking move designed to strengthen the company’s role in the critical sectors of European space transportation and defense. By securing complete control over a key supplier for the Ariane 6 program, OHB not only enhances its own portfolio but also contributes to the resilience and strategic autonomy of Europe’s access to space.

Looking ahead, the unified OHB Group is poised to capitalize on the synergistic strengths of its combined operations. The deep expertise of MT Aerospace in advanced manufacturing, coupled with OHB’s broader systems integration and satellite capabilities, creates a formidable player in the European aerospace landscape. As the global launch and defense markets continue to evolve, this consolidation provides the stability, agility, and scale necessary to innovate and compete effectively, ensuring that the group remains at the forefront of creating space and security solutions for the future.
