Netherlands Replaces MK48 with French F21 MK2 on Orka-Class Submarines

The Dutch Ministry of Defense announced on 4 March 2026 that it has selected the French F21 MK2 heavyweight torpedo for its future Orka-class submarines, departing from the original plan to integrate the American MK48 currently deployed on the in-service Walrus-class fleet.

The loss of planned MK48 integration on the Orka-class reduces the installed base for U.S. submarine weapons across NATO's next-generation platforms, weakening the economic moat RTX relies on for long-term sustainment contracts and upgrades.

If other European navies (Germany, France, Italy) follow with similar F21 selections on their SSK or SSN programs, the aggregate effect is a contraction of U.S. undersea weapons market share in Europe, shifting NATO submarine force composition away from U.S. torpedo standardization and complicating multinational anti-submarine warfare interoperability.

WHY IT MATTERS

This procurement decision signals a deliberate shift away from U.S. undersea weapons integration on a NATO ally's next-generation submarine platform.

The MK48, a staple of U.S. submarine doctrine and interoperability architecture, loses a planned customer in a tier-1 NATO navy. The F21 MK2 selection reflects either cost-effectiveness, technical preference, or political preference for European industrial consolidation — but the article provides no rationale, making the underlying driver unclear.

If this reflects a broader Dutch or European pivot toward French-led defense autonomy (rather than a one-off procurement), it could cascade into NATO submarine force interoperability challenges and reduce U.S. torpedo manufacturer market share in Europe.

RTX (Raytheon Missiles & Fire Control, MK48 prime) loses a planned integration contract; DCNS/Naval Group (F21 producer) gains platform lock-in on a multi-decade submarine class.

WHAT THIS DOESN’T TELL US

The article does not disclose the rationale for the switch, the cost differential between MK48 and F21 MK2, the timeline for Orka-class deployment, whether this decision was driven by technical, political, or economic factors, or whether other NATO navies are considering similar moves away from U.S....
