The U212 NFS (Near Future Submarine) Programme is the most advanced submarine project ever undertaken by Italy. Since 2021, it has been managed by OCCAR, bringing together a clear governance structure and a practical approach to handling complexity.

The Programme addresses a straightforward need: to operate effectively in an increasingly demanding and evolving underwater environment, ensuring surveillance, control and sea-denial where it matters.

The U212 NFS submarines are designed to cover a broad range of missions, both nationally and in support of allied commitments, including NATO and the European Union. This spans from traditional military tasks to the protection of Sea Lines of Communication and Critical Underwater Infrastructure, as well as seabed operations, counter-terrorism, intelligence, surveillance and reconnaissance, deterrence and strategic strike roles.

Starting from the proven U212A class, the new submarines introduce concrete improvements in endurance, operational effectiveness and flexibility. These include an extended pressure hull, updated combat and platform control systems, and solutions tailored for operations in warm waters. Features such as electric hoistable masts, low-profile periscopes and lithium-ion battery propulsion further enhance performance while reducing detectability.

The weapon suite provides a solid underwater strike capability and is supported by integrated countermeasure systems. At the same time, the platform is designed with future upgrades in mind, including long-range strike options.

Cybersecurity is treated as a built-in requirement, alongside careful attention to human factors, to ensure both system resilience and effective crew operation. The Programme also creates a basis for future developments, including mid-life updates to the U212A Class, support to special operations, and the integration of autonomous underwater vehicles.

The scope goes beyond the submarines themselves. It includes a fully integrated training centre and activities to modernise supporting infrastructure, aligned with the technological demands of the new class.

The Programme is currently in the production phase, with all four submarines under construction.

U212 NFS EVO
In June 2024, the Italian Navy unveiled its plan for the fleet development for the period 2025 - 2050. It includes the development of a sub-class of the U212 NFS which will be larger (> 2,000 tonnes) and which will integrate technologies in development for the successor of the Todaro class, the NGS (Next Generation Submarine).
