As part of the development of the Italian Navy submarine force for the period 2025 - 2050, the Mameli class - U212 NFS (Near Future Submarine) and the U212 NFS EVO are being developed, for an introduction by 2036. By then, the Italian Navy will be equipped with four (the U212A), four U212 NFS, and two U212 NFS EVO.
The Italian Navy is already preparing the development of the successor of the U212A, the NGS (New Generation Submarine) that will replace the U212A and that will start to be built from 2040. The Italian Navy is also developing a LDAUV (Large Displacement Autonomous Underwater Vehicle) to support the submarine force.
Project history
U212 NFS In 2018 and 2019, the Italian Parliament released information regarding the funding of the successor of the 4 submarines in order to maintain an 8-submarine force.
In November 2020, the Italian ministry of defence released their multi-year planning document (Documento Programmatico Pluriennale) for 2020-2022 It mentions the plan to procure four new submarines in two phases for a total programme cost estimated at €2.68 billion.
The Italian Government mandated OCCAR to manage the U212 NFS programme on its behalf.
Phase 1 The phase 1 comprises:
Development of the U212 NFS submarine class Procurement of 2 submarines Construction of a training center 10 years technical-logistic in-service support
In February 2021, OCCAR and Fincantieri S.p.A. (lead contractor) signed the contract of the phase 1 for €1.35 billion.
Phase 2 The phase 2 of the programme has 2 submarines that were to be purchased as an option. It includes:
Complementary development of the class Procurement of 2 submarines 10 years technical-logistic in-service support for the 2 additional submarines
In December 2022, OCCAR committed to a third U212 NFS submarine. In July 2023, the contract was signed for a value of €500 million, and a complementary budget of €160 million for additional developments was also included in the contract.
The fourth U212 NFS was ordered in June 2024 for a value of €500 million.
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 , the NGS (Next Generation Submarine).
