Corporate history

[edit]

In 1981, Christa Fuchs took over Otto Hydraulik Bremen GmbH. Founded in 1958, the Hemelingen-based company had five employees at the time and was engaged in the construction and repair of electrical and hydraulic ship systems for the German Federal Armed Forces. Together with MBB-ERNO as project leader and the Sarstedt shipyard, OHB won the contract for the construction of the MPOSS (Multi-Purpose Oil Skimming System) lead ship in 1984. Manfred Fuchs, then director of space flight at MBB-ERNO, had the idea of entering the space industry with OHB as well. In 1985, he therefore moved to his wife's company. Among the first space contracts was the Mikroba project (microgravity with balloon), a project sponsored by the German Federal Ministry of Education and Research and the DFVLR (now the German Aerospace Center), which involved experiments in free fall. Furthermore, OHB developed a space-qualified centrifuge for the Spacelab space laboratory for testing blood and urine samples.

As the number of employees grew, the premises at Hemelinger Hafendamm became too small. OHB built a new headquarters near the University of Bremen, which was opened in October 1988. Manfred Fuchs' vision was to develop smaller and thus less expensive satellites; this was also one reason for renaming the company Orbital- und Hydrotechnologie Bremen-System GmbH in 1991. Together with the Center of Applied Space Technology and Microgravity (ZARM) at the University of Bremen, OHB developed BremSat, one of the first German small satellites. It was launched into space on board the Discovery on February 3, 1994. A further milestone was the SAFIR (Satellite for Information Relay) satellite series for position determination and object tracking, which also marked OHB's entry into the telecommunications market. As early as 1993, OHB Teledata GmbH was established for this purpose, specializing in telematics systems. In the same year, OHB built the COLUMBUS integration hall on its premises for the construction and integration of the satellites. With the acquisition of further major projects such as ABRIXAS and the growing number of employees, the company's headquarters soon became too small. Directly adjacent to the existing buildings, the new headquarters at Universitätsallee 29 were inaugurated in 1995. In 2001, a further building was constructed in what was then Karl-Ferdinand-Braun-Straße (now Manfred-Fuchs-Platz) together with a modern clean room hall.

OHB subsequently took the lead in the development of the major SAR-Lupe project, a satellite reconnaissance system on behalf of the Bundeswehr. In addition, the company was selected as a supplier for the International Space Station (ISS) and for the European Columbus station module. Meanwhile, OHB System AG and OHB Teledata AG, which had been listed on the stock exchange since the previous year, were merged to form OHB Technology AG in 2002.[2] Over the next few years, further acquisitions and the establishment of various subsidiaries followed. Among other things, OHB acquired the MAN subsidiary MAN Technologie AG (now MT Aerospace) in 2005.[3] In 2008, an attempt to acquire the three German Airbus plants in Nordenham, Varel and Augsburg failed. According to a report in Manager Magazin, the plan was to create a new listed aviation Group. Under the leadership of OHB, a company with 6,700 employees and sales of around one billion euros was to be created.[4] In 2009, OHB acquired the Italian aerospace company Carlo Gavazzi Space (founded in 1981, now OHB Italia).[5]

In January 2010, the company was awarded a contract for the construction of 14 satellites for the Galileo navigation system. The contract was worth EUR 566 million.[6][7] A year later, Berry Smutny, the CEO of OHB-System AG, was dismissed after WikiLeaks published details of a conversation Smutny had with American embassy officials. Smutny reportedly called Galileo a "stupid idea" that wasted European taxpayers' money.[8] Later in the year, the company acquired Thales Alenia Space Antwerp, which has since operated as Antwerp Space.[9] At the beginning of 2011, the previous five business segments were combined to form the two segments Space Systems and Aerospace + Industrial Products. In May of this year, the annual general meeting resolved to rename OHB Technology AG into OHB AG.[10] In addition, OHB acquired the "Space Systems Division" of Swedish Space Corporation in the same year, which was renamed OHB Sweden in the process.[11]

In addition, the company developed the modular SmallGEO satellite platform, which serves as the basis for further major projects such as the H36W-1 communications satellite of the Spanish operator Hispasat and the third generation of Meteosat weather satellites. In 2013, the company was awarded a prime contract to develop and deliver a successor to the SAR-Lupe satellite reconnaissance system.

At the beginning of September 2014, the two largest subsidiaries, Bremen-based OHB System AG and Munich-based Kayser-Threde GmbH, merged to form OHB System AG with facilities in Bremen and Munich.[12] This was followed in December 2015 by the relocation of the Munich site to a new building in Oberpfaffenhofen.[13] OHB has been registered as a European Company (Societas Europaea) in the commercial register since March 2015.[14]

With its investment in Rocket Factory Augsburg AG, the company has been participating in the development of a small launch vehicle (microlauncher) since 2018.[15]

In 2020, the restructuring of the business segments was announced. All service activities arising from space technologies and data have since been combined in the third segment DIGITAL.

In 2023 OHB was taking the US financial investing company Kohlberg Kravis Roberts on board and withdrawed from the stock exchange. The Fuchs family still holds almost 70 percent of the shares, didn´t sold any shares and will therefore remain the majority owner.[16]

The OHB protest at the ECJ's General Court is based on “allegations of theft of trade secrets”, and seeks both a suspension of the contract signatures and the cancellation of the contract award. In May 2021 ESA reported it signed the contracts to design and build the first batch of Galileo Second Generation (G2G) satellites with Thales Alenia Space and Airbus Defence and Space.[30][31]

History

Founding and Early Development

OHB was founded in 1981 in the Bremen suburb of Hemelingen, Germany, as Otto Hydraulik Bremen (OHB) by Christa Fuchs, with her husband Manfred Fuchs as co-founder and key technical leader. The company initially operated as a small hydraulics firm with five employees, specializing in the repair and development of electrical and hydraulic systems for marine applications, particularly for the German Federal Armed Forces. Manfred Fuchs, an engineer with prior experience in European space initiatives including the Ariane launcher and Columbus programme through his role at ERNO in the 1960s, provided foundational expertise that later facilitated diversification. In its early years, OHB focused on practical maritime projects, including work on oil skimming ships such as MPOSS and Knechtsand during the , while hiring initial engineers to build technical capacity. Adhering to a strategy of producing "smaller, cheaper, and better" systems, the firm expanded operations and relocated to its own facilities at the Bremen technology estate near the university in 1988, enhancing proximity to research institutions and supporting steady growth. This period marked the transition from a workshop-based operation to a more structured enterprise, laying the groundwork for entry into high-tech sectors. By the mid-1980s, OHB began pivoting toward , contributing to the MIKROBA drop capsule project in 1985 for experiments, which represented its first foray into aerospace applications. This shift built on Manfred Fuchs's background in space systems and positioned the company for further advancements, including contributions of 14 research units to the MIR 92 mission in 1992.

Expansion into Space Sector

In 1985, OHB transitioned from its initial focus on hydraulic systems for marine and applications to , developing the MIKROBA drop capsule for microgravity experiments and contributing 14 research units to the MIR '92 mission. This shift established OHB as a supplier of specialized components and subsystems for projects, leveraging ’s emerging ecosystem. The company's early efforts emphasized practical experimentation, aligning with Germany's growing involvement in (ESA) initiatives. By the mid-1990s, OHB expanded into full development, launching Brem-Sat in 1994 as its first independently built for and . Concurrently, OHB pursued applications through the SAFIR program and founded OHB Teledata in 1994 to handle ground-based data services and operations. These milestones transformed OHB from a niche component provider into a , securing initial contracts for reconnaissance and technologies. This phase of growth was driven by founder Manfred Fuchs and his son Marco, who steered investments toward high-value space contracts, culminating in the €320 million program in for five German military reconnaissance satellites. OHB's strategic pivot capitalized on public-private partnerships, particularly with the (DLR) and ESA, enabling scalable production capabilities and positioning the firm for larger-scale satellite constellations in the 2000s.

Key Milestones and Acquisitions

OHB SE achieved a pivotal expansion in 2005 through the acquisition of MAN Neue Technologie, which included MT Aerospace AG and MT , thereby strengthening its manufacturing base for structures and systems. This was followed in 2007 by the purchase of Kayser-Threde GmbH, renamed OHB System Oberpfaffenhofen, which added advanced expertise in space vehicle assembly and testing. Further international growth occurred in 2009 with the integration of Carlo Gavazzi Space into OHB Italia, expanding and capabilities. In 2010, OHB acquired the Belgian operations of , rebranded as Antwerp Space, enhancing and technologies. The following year, 2011, saw the acquisition of the Swedish Space Corporation's space systems division, establishing OHB and bolstering and expertise. Key contractual milestones included the 2001 award of a €320 million contract for the German radar reconnaissance satellite system, marking OHB's entry into defense-related space projects. In 2010, OHB secured a €566 million contract from the (ESA) to build 14 Full Operational Capability (FOC) satellites for the Galileo navigation system, later expanded to 34 satellites by 2017. The 2013 radar satellite contract further solidified its portfolio. Significant launches underscored operational successes: the 2016 arrival of the ExoMars Trace Gas Orbiter at Mars, the 2017 deployment of the H36W1 SmallGEO telecommunications satellite, and the 2019 launches of PRISMA (for autonomous satellite formation) and EDRS-C (European Data Relay System). Revenue reached €1 billion in 2019, reflecting scaled operations. More recent achievements include the 2022 launches of EnMAP (hyperspectral ) and MTG-I1 (Meteosat Third Generation imaging satellite), alongside the 2023 deployment of the communications satellite. In 2022, OHB acquired GEOSYSTEMS , a geo-information technology specialist, to augment digital services in data processing. The company also pursued strategic investments, such as agreeing in to acquire a stake in Holdings alongside AFK Enterprise, targeting sector synergies. Concurrently, KKR's 2023 minority investment of up to €338 million via a offer and capital increase provided capital for further expansion.

Recent Strategic Shifts

In August 2023, OHB SE entered into an investment agreement with KKR, under which KKR launched a voluntary public for all outstanding shares at €44 per share, valuing the company at approximately €768 million, to strengthen its capital base and support the implementation of its growth strategy while the Fuchs family retained long-term majority control as a strategic minority . This included a 10% capital increase of €77 million at the offer price, completed shortly thereafter, aimed at funding expansion in core systems and digital services amid increasing European demand for technologies. The arrangement facilitated a potential delisting from the , though OHB remained publicly traded into 2025, with management citing opportunities from competitors' consolidations, such as the Airbus-Thales-Leonardo units merger, to maintain flexibility. Following the KKR partnership, OHB initiated a comprehensive transformation program in late 2023, emphasizing , project profitability, digitalization, , and capabilities across its segments to address execution risks and adapt to a competitive landscape driven by geopolitical tensions and autonomy goals. This shift built on a strategy update presented in 2023—reiterated in 2024—shifting focus from legacy dependencies toward high-growth areas like small satellites and , evidenced by a July 2023 memorandum of understanding with for joint EO applications. The program also incorporated a new ESG framework adopted in 2024, setting KPIs and targets through 2030 for in operations and supply chains. These initiatives yielded a record order intake of €1.67 billion in , surpassing prior years and supporting revenue guidance of 16.5% growth in and an additional 25% by 2027, primarily from European government contracts in secure communications and systems. adjustments, including the appointment of Dr. Tim Tecklenburg as in September 2025, further aligned with efficiency goals.

Leadership and Ownership

Founding Family Influence

OHB SE originated from Otto Hydraulik Bremen GmbH, a small and marine systems firm established in 1958 with five employees by the time Christa Fuchs acquired it in 1981. Christa Fuchs, alongside her husband Manfred Fuchs who joined the leadership in 1985, redirected the company's focus toward , leveraging Manfred's prior experience in at firms like Messerschmitt-Bölkow-Blohm to develop payloads and subsystems starting in the early . This pivot transformed the family-controlled entity into a key player in European space systems, with the Fuchs family retaining operational and strategic oversight through direct involvement in management and board roles. Their son, Marco Fuchs, entered the business in 1995 as an authorized signatory and assumed the CEO position at OHB SE in 2000, continuing the family's hands-on influence by steering expansion into satellite manufacturing, orbital infrastructure, and international partnerships. Christa Fuchs served as chair of the at subsidiaries like OHB System AG until her departure in 2024, underscoring the intergenerational continuity in governance. The family's control has emphasized long-term stability over short-term gains, as evidenced by their establishment of the Fuchs Family Foundation in October 2022, to which Marco and Christa Fuchs transferred their direct and indirect holdings, explicitly aiming to safeguard the company's independent, family-oriented ownership structure. Despite a 2023 minority investment by Kohlberg Kravis Roberts (KKR), which acquired approximately 28.64% of shares to bolster capital for strategic growth, the Fuchs family preserved majority ownership—holding around 38.76% directly via Marco Fuchs and additional stakes through the foundation—ensuring veto power over major decisions and continuity under Marco Fuchs's CEO leadership. This arrangement has allowed the family to maintain strategic autonomy, prioritizing investments in core competencies like satellite development amid partnerships with entities such as the , while resisting full externalization of control. The family's enduring stake, exceeding 70% prior to the KKR deal, has been credited with fostering resilience and innovation in a capital-intensive sector prone to volatility.

Contract Disputes and Litigation

In 2021, OHB System AG, a key subsidiary of OHB SE, challenged the European Commission's decision to award a multi-billion-euro contract for the second-generation Galileo satellite constellation to a consortium led by Airbus Defence and Space and Thales Alenia Space Italia. The tender, initiated by the European Space Agency in 2018, aimed to develop transition satellites for the Galileo navigation program, for which OHB had previously supplied most of the first-generation units. OHB alleged that Airbus obtained an unfair competitive edge by hiring its former chief operating officer, who possessed sensitive proprietary information from OHB's prior work, and requested Airbus's exclusion from the tender. The Commission rejected this request in January 2021, prompting OHB to seek annulment of the award in the EU General Court. The General Court dismissed OHB's action, finding insufficient evidence of irregularity. On appeal, the EU Court of Justice upheld the dismissal on April 26, 2023, ruling that OHB's claims of were too vague and hypothetical to warrant further Commission investigation. However, on June 12, 2025, the ECJ set aside the General Court's judgment in Case C-415/23 P, referring the matter back for reexamination. The ECJ held that the Commission has a duty to probe objective indications of conflicts of interest to ensure equal treatment among bidders and to implement if violations are found, potentially reopening scrutiny of the contract award process. Separately, in 2019, U.S. firm ValveTech, Inc. initiated breach-of-contract litigation against OHB System AG in the U.S. District Court for the Western District of New York (Case No. 6:19-cv-06829), centered on 4552785 for a specialized spare valve intended for satellite applications. ValveTech claimed OHB violated non-disclosure agreements by exporting the valve to in without consent and by retaining proprietary data, while seeking a that the was unenforceable. OHB counterclaimed for ValveTech's alleged failure to deliver conforming valves, with its business relations with Thales, and promissory . On January 3, 2023, the court granted partial : dismissing ValveTech's declaratory and claims but allowing its core breach-of-contract claim to proceed to trial; it also dismissed OHB's counterclaims while permitting OHB's breach-of-contract and promissory claims to advance. No public record indicates a final resolution, suggesting the dispute may have settled out of court or remains pending. These cases highlight OHB's involvement in disputes over procurement fairness and obligations in high-stakes contracts, though neither has resulted in adverse judgments against the company to date.

Regulatory Challenges

OHB SE, operating in the highly regulated European space sector, encounters challenges stemming from procurement rules and export controls on dual-use technologies. The company's heavy reliance on institutional contracts from the (ESA) and national agencies subjects it to stringent oversight in bidding processes, where decisions can favor competitors amid allegations of irregularities. A prominent example is the prolonged litigation involving OHB System AG, a key subsidiary, against the over Galileo program contracts. In 2021, OHB challenged the €1.47 billion award for second-generation Galileo satellites to and , claiming the rivals obtained trade secrets through the hiring of an OHB executive and other unfair practices. The General Court dismissed OHB's initial action in April 2023, ruling that the Commission had adequately justified the award despite procedural concerns. However, OHB appealed, and in June 2025, the (ECJ) annulled parts of the lower court's decision, mandating a fresh review of the contract due to potential breaches in transparency and rules. This case underscores broader difficulties in contesting regulatory decisions on public tenders, which prioritize but can lead to disputes over alleged favoritism or insufficient safeguards against risks. As of October 2025, the litigation persists, influencing OHB's strategic positioning in Galileo transitions. Beyond , OHB navigates complex and controls applicable to hardware and , governed by dual-use regulations and international frameworks like the . These rules restrict transfers of sensitive technologies to prevent proliferation, requiring rigorous compliance to avoid penalties. OHB addresses this through dedicated internal structures, including an Export Compliance Officer and board-level oversight, as outlined in its . The regulated market environment further constrains pricing flexibility, as fixed-price contracts with public entities limit margins amid fluctuating costs. No public records indicate violations or fines against OHB for regulatory non-compliance, reflecting proactive measures amid industry-wide scrutiny.

Criticisms of Operations

OHB SE's subsidiary OHB System AG served as prime contractor for the SARah military reconnaissance satellite program, intended to provide Germany with synthetic aperture radar imaging capabilities. In December 2023, two reflector satellites launched aboard a SpaceX Falcon 9 rocket failed to deploy their antennas, rendering them non-operational despite initial successful orbit insertion. By July 2024, attempts by OHB engineers—including software resets and orbital maneuvers to vibrate the antennas—had not resolved the issue, prompting the German Ministry of Defence to blame OHB and demand an updated action plan. As of May 2025, partial recovery hopes persisted, but the satellites' persistent problems highlighted potential deficiencies in OHB's design, testing, or manufacturing processes for critical deployable components. This failure, part of a €900 million contract, contributed to a €25 million impairment charge on a classified system in OHB's 2024 financials, exacerbating a 13% revenue decline and sharp profit drop. The EnMAP hyperspectral imaging satellite, also led by OHB System as prime contractor for the German Aerospace Center, faced significant developmental delays attributed to technological and engineering challenges, postponing launch by approximately a decade from initial plans. These issues primarily involved the satellite's advanced imaging payload, which required overcoming mass budget constraints and complex hyperspectral sensor integration. Despite eventual launch in July 2022 via SpaceX, the protracted timeline drew criticism for inefficient project execution in a program aimed at environmental monitoring with a budget exceeding €150 million. In the Galileo navigation , OHB System constructed the majority of satellites under contracts, but the program encountered repeated delays partly ascribed to OHB's performance. Vice President in 2010 explicitly blamed both the ESA and OHB for setbacks in deployment and system readiness. Early satellites suffered from clock failures and other reliability issues, contributing to overall program overruns exceeding initial estimates by billions of euros and pushing full operational capability beyond original 2014-2020 targets. These operational shortcomings underscored recurring challenges in OHB's design and subsystem integration for high-reliability missions.
