TKMS-Navantia Partnership: Building a Stronger European Submarine Fleet.

TKMS-Navantia MoU Signing Ceremony.
TKMS and Navantia MoU for European Submarine Project: The European defence landscape is undergoing a major shift. Two of the continent’s premier naval shipbuilders, Germany’s TKMS and Spain’s Navantia, have officially signed a second Memorandum of Understanding (MoU). This agreement takes their earlier partnership to the next level, with a clear goal to establish a formal joint collaboration framework for selected submarine projects by the end of the year, subject to regulatory approvals.
In simple terms, the two companies want to work closely together on future submarine projects. Instead of competing on every front, they plan to combine their unique strengths to build better submarines faster, helping to meet a growing global demand for advanced underwater defense technology.
Why This Partnership Matters Now
Geopolitical challenges around the world are putting a heavy spotlight on the security and self-reliance of Europe. Modern navies need cutting-edge submarines, but building them is complex, costly, and time-consuming.
By joining forces, TKMS and Navantia hope to solve these bottlenecks. The partnership is designed to expand industrial capacity, speed up delivery timelines, and boost long-term technological innovation. Company leaders emphasise that this move directly supports the continent’s broader goals.
“Europe’s security requires a stronger and more resilient industrial base,” says Oliver Burkhard, CEO of TKMS. “This Memorandum of Understanding marks an important step towards combining complementary industrial strengths while preserving the technological leadership, design authority, and quality standards that define TKMS. By combining our strengths, we will reinforce Europe’s industrial base and sovereignty in the defense sector, thereby contributing to greater strategic autonomy for Europe.”
Echoing this sentiment, Ricardo Domínguez, Executive Chairman of Navantia, points out the global scale of the challenge: “Navantia and TKMS are making concrete progress to foster Europe’s strategic autonomy, working in the creation of a robust and scalable industrial defence base, capable of responding to a sustained growth of global demand in design, building and sustainment of submarines. This MoU highlights Navantia’s capacities in the submarine domain, reinforces our presence in this market and is a testament to our role in European defence.”

What the Agreement Means (and Doesn’t Mean)
For those watching the corporate side of the defence industry, it is important to note what this MoU does not entail. There is no merger happening, and neither company is acquiring shares or assets from the other.
Furthermore, all existing contracts, active programmes, and ongoing projects will remain completely independent and unaffected. The collaboration is strictly forward-looking, aimed at future international opportunities.
Dr. Andreas Görgen, COO of TKMS, explains how this balance will work in practice: “Today’s MoU reflects the excellent progress of our discussions and the strong commitment of both partners to create a new model combining the strengths of TKMS and Navantia in selected areas, expanding opportunities for both companies and providing our customers with greater industrial capacity, technological excellence and enhanced delivery performance. At the same time, both partners will continue to operate independently and remain fully committed to their existing programmes and customers.”

Looking Ahead: The Road to Year-End
Over the past three months, constructive discussions have helped both shipbuilders identify exact areas where their combined expertise creates genuine extra value for customers.
The upcoming months will involve navigating regulatory processes, ensuring full compliance with competition laws and export-control regulations, and securing appropriate customer approvals. If everything goes to plan, the formal joint collaboration framework will be finalized before the year is out.
Gonzalo Mateo-Guerrero, Navantia Chief Operating Officer, highlights the practical benefits of this roadmap: “This new MoU marks progress towards a collaboration model with the purpose of enhancing delivery competitiveness and establishing a long-term technological partnership to supply cutting-edge defence products. It builds upon the strengths of Navantia and TKMS while ensuring that each company retains its own technologies and design authority on their respective programmes and contracts.”
Ultimately, this partnership signals a pragmatic new era for European defence engineering—one where cooperation helps bridge the gap between rising global demand and the need for swift, high-tech naval solutions.
