Torpedo choice reshapes Dutch submarine plans, ministry says
The Dutch Ministry of Defence has selected the French F21 MK2 heavyweight torpedo for its future Orka-class submarines, abandoning earlier plans to equip them with the American MK48 torpedo. The decision covers four new Orka-class boats and follows a Ministry assessment that accelerated replacement of the MK48 is feasible. The shift is driven by growing concern about unmanned enemy systems and anti-torpedo defenses, and the first submarine delivery is scheduled from 2033.
Why the Torpedo switch matters
The Ministry framed the move as a direct response to rapidly evolving threats that require higher precision and defensive resilience. Officials emphasized that modern unmanned and manned systems capable of deploying anti-torpedo measures have changed the tactical environment, pushing the Netherlands to prioritize an advanced heavyweight torpedo now instead of retaining the current MK48 fit-out. Choosing the F21 MK2 aligns the new submarines with a partner that already fields the same weapon system, which the Ministry said will improve shared tactics and operational knowledge about torpedo deployment.
Details of the selection and industrial link
The supplier selected is the French Naval Group, which also builds the Orka-class submarines. The initial plan had been to integrate the MK48 torpedoes used aboard the in-service Walrus-class submarines, but the Ministry decided against that because an accelerated replacement of the MK48 now appears feasible. The decision ties weapons integration directly to submarine construction during the production phase, allowing the F21 MK2 to be embedded as the primary heavyweight torpedo for the new fleet.
What this means next
Operationally, the choice will alter training, logistics and cooperative planning with EU and NATO partners who operate the same weapon system. The Ministry highlighted that sharing knowledge about deployment tactics with France is expected to increase the weapon’s effectiveness in high-intensity scenarios. Industrially, the link to the French Naval Group creates a single supply and integration path for both hull and armament during build.
Looking ahead, the Ministry’s timetable points to the first Orka-class submarine entering service from 2033, and planners will now work through integration testing, crew training and allied tactical alignment. The Ministry signaled that decisions on replacement of legacy MK48 stocks and timelines for broader fleet transition will follow once production-phase integration and initial trials of the F21 MK2 are underway. The torpedo choice marks a clear strategic pivot intended to keep the submarine force effective against emerging anti-submarine and anti-torpedo threats, and officials expect further announcements on implementation steps as construction progresses.
