Netherlands next-generation conventionally-powered attack submarine based on French Barracuda-class design — the largest and most ambitious Dutch submarine programme in decades. Netherlands plans to procure 4 submarines replacing Walrus-class boats (commissioned 1990-1994) which are approaching end of service life. Contract negotiations with France ongoing through mid-2020s with construction potentially beginning late 2020s. The Orka-class will be a conventionally-powered derivative of the French nuclear Barracuda (Suffren-class) optimized for diesel-electric operations. Expected features include displacement of approximately 4,500-5,000 tonnes, modern Air Independent Propulsion (AIP) system providing extended submerged endurance, advanced sonar suite, six 533mm torpedo tubes for heavyweight torpedoes and potentially submarine-launched cruise missiles, special forces delivery capability, extensive automation reducing crew requirements, and modern combat management systems. Significantly larger than previous Dutch submarines enabling longer patrols and greater payload. The Orka represents strategic Dutch-French naval cooperation and Netherlands committing to maintaining world-class submarine capability for monitoring sea lanes, intelligence gathering, and maritime security. Projected service entry 2030s with final boat delivered 2040s.

- Based on Barracuda nuclear submarine design adapted to conventional propulsion
- Lithium-ion batteries expected to provide extended submerged endurance
- Advanced French sonar and combat management from nuclear submarine lineage
- Will significantly modernize Dutch submarine capability over aging Walrus class
- High-risk adaptation from nuclear to conventional propulsion design
- Long development and build timeline — deliveries not before early 2030s
- Cost escalation risk inherent to complex submarine programs
- Dutch submarine industrial base has atrophied since Walrus construction in 1990s
