Executive Summary
The German F126 frigate program, supposed to serve as the foundation of Germany’s naval combat capabilities in the future, is beset by major setbacks, increased expenses, and poor industrial coordination. Initial operational capability has been delayed into the early 2030s after years of development and more than €1.8 billion in expenditures, resulting in an increasing capability gap for the German Navy. Germany’s NATO maritime commitments are also under increasing strain due to the ageing F123 fleet and increased Russian submarine activity. There is a significant strategic risk associated with continuing to use the F126 as the main solution.
This Whitepaper discusses how the F 126 became a liability and argues for the quick acquisition of tested interim frigates, like the MEKO 200. The German Navy must have combat-ready ships available to maintain a credible deterrence.
Introduction
While the cancellation of the US Navy’s Constellation-class frigate program sparked significant controversy within NATO naval circles at the end of 2025, another problematic program on the brink of cancellation has progressed more quietly in Europe (Katz, 2025). “Sailing under the radar,” in Navy parlance. This is Germany’s spearhead surface-combatant project: the F126 anti-submarine frigate program, also known as the “Niedersachsen class.”
What began as an ambitious project for the most modern and biggest frigates in Europe in the early 2010s developed into a textbook example of mismanaged project work between stakeholders, digital interface management, and project management, resulting in years of delays and spiraling development costs. At this point, the project is nearly four years into development and has already consumed over €1.8 billion, with estimated delivery of its first operational ship delayed over three years well into the 2030s (Geiger & Hoffmann, 2026).
Meanwhile, the German Navy is desperately in need of new, primarily anti-submarine frigates, because of their aging fleet of F123 “Brandenburg class” frigates and the rising perceived threat of Russian naval activity in the Baltic and North Sea.
This development prompted the German Parliament to act. Since time is of the essence, the representatives face varying options for the project going forward, with very different expected strategic, economic and political effects.
Strategic Background
The F126 was intended to be a direct replacement of the F 125 “Baden-Württemberg” class. The F125’s design philosophy was almost entirely centred on long-term stabilisation missions and international crisis management in low-level-threat, permissive environments. However, a significant geopolitical shift toward high-intensity state-on-state conflict clashed with long development cycles. The four F125 frigates already appeared outdated when they entered service in the early 2020s (Rogoway, 2017). Widely criticised as being under-gunned for their size and price, unit costs close to one billion euros, displacement of about 7.500 tonnes, and armament that consisted primarily of a single 127 mm gun and light defensive weapons, earned the boat an unofficial nickname: “nice weather boats” (Bundeswehr, 2023).
F126 was intended to be the country’s return to a blue-water frigate capable of combat. A large, modular, globally deployable frigate with three-dimensional warfare capabilities was envisioned. To adapt to various tasks, the new frigate would combine endurance with increased firepower and modular mission bays (similar to the original idea of the F125). Despite being technically ambitious, the design was controversial because it only had 16 VLS (Vertical Launch System) cells, for warships with an estimated future displacement of about 10.000 tonnes (Damen Naval, 2020). This represents a relatively small missile capacity when compared to ships of a similar size. For instance, the US Navy’s Arleigh Burke-class destroyer has between 90 and 96 VLS cells (Pierce, 2025)
The Project History:
The project started under the name of MKS 180 (Mehrzweckkampfschiff) in 2015 as the German Navy’s first European tender, comprising four identical ships of that class. Changing design and performance requirements, its European component and the German federal elections in 2017 prolonged the decision process, with three main company consortia as competitors (Geiger & Hoffmann, 2026).
In June 2020, the tender for the F126 program came to a close, with the Dutch Damen Shipyard Group being awarded the prime contractor role, with a variety of German companies as subcontractors. The decision was ultimately driven by budgetary considerations, as Damen’s offer was considered less expensive than that of other potential contractors. This choice was politically controversial from the outset, as it bypassed proven domestic naval shipyards such as NVL and TKMS. To calm the opposition, Damen had to ensure that most of the construction work would be done in German shipyards so that the majority of value creation would be done in Germany itself (MarineForum, 2025).
After the initial decision, however, the project seemed to run under the radar, with its construction phase officially starting in December 2023 and the metal work for the first F126 Niedersachsen beginning in June 2024 (Damen Group, 2024).
The first signs of delays began to show shortly after. In the 19th armament report of the German Department of Defense (DoD), problems between the IT interfaces of Damen and the German shipyards regarding the construction plans of the F126 are mentioned, but were ultimately, with reference to project time buffers, accepted (BMVg, 2024a).
This warning did not stop the German Federal Procurement Office (BAAINBw) from ordering two more frigates on 20 June 2024, ramping up the number of ships ordered to a total of six (BMVg, 2024b).
The IT interface problems emerged as a larger problem than anticipated, leading to a practical stop at the construction sites and further delays. The cornerstone of the problem for the Damen Group seemed to be the implementation of the blueprints into the Dassault software, which is responsible for the translation of the documents into construction on the German site (MarineForum, 2025).
In June 2025, the German DoD informed the parliament of substantial delays in the program, pushing the delivery of the first frigate from its originally planned 2028 date to 2031. Even worse, with slipping project milestones and conditional payments falling flat, the Damen Naval Group was on the brink of bankruptcy. Only a special bridging loan of the Dutch government of over €270 million saved the company going forward. Adding to the pressure, Damen also faces, from 2025, a corruption charge by the Dutch government for slipping Russian sanctions. The future survival of the Damen Group remains uncertain (MarineForum, 2025).
Even though the German DoD officially still backs the project, as of June 2025, a simple continuation of the project under the existing framework can be seen as highly unlikely.
Possible Solutions for the German Navy Going Forward
Cancellation and Repayment
The German BAAINBw and DoD could opt for a cancellation of the project outright. In this case, some of the already committed €1.8 billion budget could be partially reimbursed, depending on the exact legal obligations and failed milestones. This is the least likely option, as European defense reimbursement processes did constitute very long legal disputes in the past (MarineForum, 2025). Even more important, Germany would need to start from scratch, losing all progress made in the program, which would not be economically and technically viable and would also prolong the already expected capability gap for the German navy. In the end, speed is the key.
Takeover of the Project by a German prime contractor
A second option would have the program taken over by a German prime contractor under a complete industrial reset. This would most likely be NVL due to their already substantial involvement in the construction part of the program. NVL would likely take several steps including restructuring leadership, re-baselining schedules and regaining tighter national control over critical development phases. While politically sensitive and likely to cause further delays, this path would preserve the original vision of the F126 as Germany’s future core combatant, sacrificing short-term readiness in exchange for long-term modernization and industrial sovereignty (Speer, 2025).
Splitting the Requirements of the F126 onto different Ship Classes
A third and most likely option sees the preservation of the F126 in reduced quantity, while simultaneously introducing a small number of a simpler, proven interim class. This would most likely be based on the TKMS MEKO 200 family (MarineForum, 2025). These ships could be built relatively quickly by TKMS, since it represents a completed and standardized design, which was already built in quantity in many variations for countries like Egypt (Sharma 2022). Even though the frigates do not fulfill the full range of the requirements of the F126 design, they are sufficient in core requirement areas such as armament, survivability and agility. TKMS officially stated that they could deliver the first operational vessel in 2029, drastically closing the gap to the original delivery date for the F126 of 2028 (Mergener, 2026). This would restore fleet numbers and NATO commitments.
On the other hand, the F126 program would continue slowly in the background. In this model, the Niedersachsen class would quietly lose its role as Germany’s main future combatant and instead become a limited high-end supplement.
Recent Developments in Regards to the Future of the F126:
The third option seems to be the path Germany is heading towards. As of 4 February 2026, the BAAINBw and TKMS agreed on a preliminary agreement worth €50 million for the purchase of at least three MEKO 200 DEU frigates. This agreement sets the stage for first material procurements and preliminary construction works until March 2026 (Mergener, 2026).
This comes as the federal German budget committee already earmarked a financial framework of around €7.8 billion for a potential F126 alternative in the German 2026 defense budget in November 2025. This budget could, depending on the developments of the F126 program, be committed partially or fully to procuring MEKO frigates. If indeed committed fully, the budget would be enough to roughly buy eight vessels with unit costs of around €1 billion each (Deutscher Bundestag, 2025).
At the same time, NVL has signaled at the end of January 2026 that they were able to fix the IT interface problems, transferred Damen’s design data clearly and are therefore now able to restart operational production, which also signals the ability to take over the program entirely (Klein, 2026).
A final decision of the DoD on the future of the F126 was therefore again postponed and is expected to be made sometime in spring 2026.
Policy Implications
Given the rapidly widening capability gap of the German Navy, policy decisions must prioritize speed, reliability and fleet availability over the preservation of an increasingly uncertain flagship program. Germany’s contribution to NATO’s maritime deterrence in the North Atlantic and Baltic is directly weakened with each year that the F126 program is delayed.
The rapid acquisition of frigates based on the MEKO 200 DEU should be viewed as a key component of German naval strategy for the 2030s. Early commitment to the complete purchase of up to eight vessels would enable economies of scale, give industry planning certainty, and facilitate the quickest possible return to operational numbers of surface combatants.
At the same time, the F126 program should no longer be regarded as the future backbone of the fleet. Continuing it in reduced numbers, or suspending it pending further industrial stabilization, would limit financial exposure while preserving the option of retaining selected high-end capabilities. Any continuation under Damen as prime contractor must account for the company’s financial and legal uncertainties, while a transfer to a German prime contractor would likely entail further delays and organizational risk.
To mitigate capability shortfalls, the MEKO fleet should be complemented early by unmanned aerial, surface and underwater systems, enabling a manned–unmanned approach to anti-submarine warfare. Such systems can be procured on significantly shorter timelines and partially offset the absence of a high-end frigate class. That is at least what Vice Admiral Jan C. Kaack, Inspector General of the German Navy, sees in the “Course 2025” as the way forward (MarineForum, 2025).
While terminating or downgrading the F126 would carry political and reputational costs, allowing sunk costs to dictate future force structure decisions would pose a greater strategic risk. In the current threat environment, restoring credible and deployable naval combat power must take precedence over maintaining an increasingly fragile procurement concept.
