Belgian Navy Frigate Delivery Delayed to 2034, Seven Years Behind Schedule
The delivery of new anti-submarine warfare (ASW) frigates for the Belgian Navy has been delayed by multiple years, with the first Belgian vessel now not expected until at least 2034 — seven years later than originally planned, according to VRT NWS. The setback leaves Belgium facing a critical naval capability gap as its two aging frigates approach the end of their operational lives.
Background: A Decade of Delays
The frigate replacement program dates back to June 2018, when Belgium and the Netherlands signed memoranda to jointly replace their aging M-class frigates. The original plan called for the first Belgian frigate to enter service by 2027. VRT NWS reported at the time that the agreement marked “the real starting signal for the replacement of our ships,” according to then-Defense Minister Steven Vandeput.
However, the timeline has slipped repeatedly. The target moved from 2027 to 2030-2031, and now to at least 2034. The Netherlands, which leads the joint procurement, has also seen its first ASW frigate delayed to 2033 — a three-year setback attributed to “technical complexity of the design.”
Design Flaws and Cost Explosion
The Dutch Ministry of Defense confirmed that “the original ship design proved to be unstable,” requiring design adjustments to meet requirements for flexibility in space and weight for future system integration. The revelation came in a Dutch Defense projects overview published in mid-May 2026.
Meanwhile, costs have spiraled dramatically. The price per ship has risen from an initial estimate of €600 million to over €1 billion, with an additional €250 million per vessel now anticipated. VRT NWS defense expert Jens Franssen described the situation as a “price explosion,” citing a source close to the file.
“The project has already suffered an enormous amount of delay,” Franssen told VRT NWS. He identified four key factors behind the setbacks: insufficient budget as Belgian Defense faced spending pressure, disagreements between Belgium and the Netherlands over ship design and capabilities, lost industrial expertise in Dutch shipbuilding, and the design instability that required correction.
A Looming Capability Gap
Belgium currently operates two frigates — the Leopold I and Louise-Marie — both former Dutch M-class vessels acquired in the 2000s. These ships are reaching the end of their operational lives and cannot be extended to 2034, according to Franssen.
“We risk temporarily falling without real warships or frigates,” Franssen warned. “Our country has a capacity problem.”
The capability gap would severely limit Belgium’s naval defense and its ability to contribute to NATO operations at a time of heightened European security concerns. Belgium has been under pressure to increase defense spending, and this procurement failure raises questions about its credibility as a NATO ally.
Emergency Solutions Sought
Belgian Defense Minister Theo Francken (N-VA) met with his Dutch counterpart Dilan Yeşilgöz in early May 2026 to address the crisis. According to VRT NWS, they agreed to seek emergency solutions in the coming weeks. Potential options could include leasing vessels, extending the life of current ships, or other interim measures, though no specific plans have been announced.
The difficulties also raise questions about Belgium’s ambition to order a third frigate. Franssen noted that “fear exists that the purchase of the third frigate could even be canceled.”
Broader Implications
The ASW frigate program is a joint project between Belgium and the Netherlands, with Dutch shipbuilder Damen Naval and Thales Netherlands as prime contractors. The total order covers four frigates (two for each country), with the Netherlands ordering two additional vessels for a total of six.
The technical challenges faced by Damen highlight broader concerns about European naval shipbuilding capacity and the loss of expertise required to construct complex warships. The delays come at a time when NATO allies are under pressure to strengthen their naval forces amid global security challenges.
What to Watch For
In the coming weeks, attention will focus on the emergency solutions being explored by Francken and Yeşilgöz. Key questions include whether Belgium can extend the operational life of its current frigates, what interim naval capabilities might be secured, and how the cost escalation will affect Belgium’s defense budget and its plans for a potential third frigate. The outcome will have lasting implications for Belgium’s naval posture and its role within NATO.
