Belgian Navy Faces Warship Gap as Belgium Threatens to Pull Out of Deal

Belgium’s navy is staring down an unprecedented capability crisis as its two aging frigates reach the end of their operational lives and the government signals it may withdraw from a billion-euro joint warship purchase with the Netherlands. With both vessels sidelined and replacements potentially a decade away, the country faces a multi-year gap in its ability to conduct naval patrols, participate in NATO missions, and train new personnel.

According to VRT NWS, the Belgian government is actively exploring alternatives to the joint Anti-Submarine Warfare (ASW) frigate program with the Netherlands, a project that has been plagued by repeated delays and staggering cost overruns. Prime Minister Bart De Wever (N-VA) is scheduled to meet Dutch Prime Minister Rob Jetten in early August 2026 to resolve the crisis, with a final decision expected before the end of the year.

A Fleet at Breaking Point

Belgium operates just two frigates — the Leopold I (built 1991) and the Louise-Marie (built 1988) — both second-hand ships acquired from the Dutch navy. After nearly 40 years of service, both vessels are technically obsolete and increasingly unreliable. The situation reached a critical point on July 5, 2026, when the Leopold I was stranded in Norfolk, Virginia, with a catastrophic cooling system failure. As VRT NWS reported, the Louise-Marie entered scheduled maintenance shortly afterward, leaving Belgium temporarily with zero operational frigates.

“You can’t keep sailing around with old frigates until 2034,” said Vice Admiral (ret.) Wim Robberecht, a former commander of the Leopold I, in comments to VRT NWS. An internal study conducted as early as 2025 reportedly concluded that it was no longer worthwhile to repair the aging vessels.

The Dutch Deal Unravels

The joint frigate replacement program was initiated in 2016, with a formal agreement signed in 2018 for four identical ASW frigates — two per country — with the Netherlands taking the lead and Dutch shipbuilder Damen Shipyards designated as the builder. The original per-ship cost estimate of €500 million has since ballooned to approximately €1.3 billion, a 160% increase, with the Netherlands recently indicating further cost hikes of at least €250 million per vessel.

Delivery timelines have proved equally disastrous. Originally scheduled for 2027, then pushed to 2030-2031, the latest Dutch estimates point to 2034 at the earliest. Notably, as government sources told VRT NWS, “not a single piece of metal has been cut” for construction.

“This is a problem that can no longer be solved with money alone. The Dutch simply are not doing — or can no longer do — what they promised us,” Chief of Defense Frederik Vansina told VRT NWS.

Defense Minister Theo Francken described the situation as a “major problem” in comments to NOS, the Dutch public broadcaster. Trust has evaporated. As one anonymous naval source told VRT NWS: “Delivery deadlines are pushed back year after year. Trust in the Dutch is gone.”

Searching for Alternatives

Francken has announced plans to formally request proposals from shipyards across Europe, including France’s Naval Group (FDI frigates), Italy’s Fincantieri (FREMM EVO), Germany’s TKMS (MEKO A200), Spain’s Navantia (F110), and Turkey’s Istanbul-class shipyard. According to Marineschepen.nl, a leading naval news outlet, the minister intends to make a decision by October 2026.

Turkey has made a particularly aggressive offer, with government sources claiming it can deliver three frigates by 2027 for the price of two Dutch ships. However, Belgian naval sources express reservations, noting that Turkish vessels are designed for Mediterranean conditions rather than the Atlantic and Arctic waters where Belgium operates.

Each alternative comes with significant trade-offs. German MEKO A200 frigates are proven exports but cost between €1.3 and €1.66 billion per unit. French FDI frigates benefit from a larger production run — 13 already ordered by France, Greece, and Sweden — but past friction with French defense industry complicates cooperation. Defense Minister Francken himself has noted that working with the French has historically been difficult.

BeNeSam at a Crossroads

The crisis threatens the Belgian-Dutch naval cooperation (BeNeSam), one of the deepest military integrations between sovereign nations in Europe. Dating back to 1948, BeNeSam encompasses a joint naval headquarters in Den Helder, shared ship classes, joint training, identical uniforms, and integrated logistics.

“Where the Netherlands now looks more toward Germany and Northern Europe, Belgium still looks toward the Netherlands. They want to protect and build upon that Benelux cooperation,” defense expert Michelle Haas of Ghent University told NOS.

As one naval officer noted: “In the budgetarily difficult past 20 years, it was the Dutch navy that kept us afloat. Not Zeebrugge, but the Dutch Den Helder was our most important home port.”

Damen’s Broader Crisis

The Belgian situation unfolds against a backdrop of wider problems at Damen Shipyards. In June 2026, Germany withdrew from a separate multi-billion euro contract for six F126 frigates, citing delays and cost overruns. Damen is also under criminal investigation for allegedly circumventing sanctions against Russia. The Dutch government is reportedly considering taking an equity stake in the shipbuilder to secure naval shipbuilding capacity.

Strategic Implications

The crisis raises fundamental questions about European defense industrial capacity and the viability of joint procurement. For Belgium — a maritime nation with three major seaports (Antwerp, Ghent, and Zeebrugge) and a large dredging and tanker fleet — the stakes are existential. Without frigates, the country cannot protect its maritime interests, escort commercial shipping in high-risk areas, or contribute to NATO missions requiring frigate-class vessels.

There is also a growing debate about whether traditional multi-role frigates remain viable given the rapid proliferation of underwater drones, AI-driven “wolf packs” targeting warships, and cheaper unmanned platforms. As one government source told VRT NWS: “More and more, the choice is for cheaper platforms, sometimes unmanned. Maybe those expensive all-rounders are no longer of this time.”

What’s Next

All eyes are on the early August meeting between Prime Ministers De Wever and Jetten. Belgium faces a difficult choice: stay with the Damen program and accept a decade-long wait, or break with the Netherlands and pursue alternatives that may preserve naval capability but at the cost of a historic partnership. Either way, the decision will reshape Belgian defense policy for a generation.

As Francken has indicated, a decision will be made by October 2026. For the Belgian navy, the clock is ticking.
