Naval Group and METLEN sign a memorandum of understanding related to submarine and frigate projects for the global markets

On 19th March 2026, Naval Group and METLEN signed a memorandum of understanding (MoU) at M Technologies’ (METLEN’s defence arm) facilities in Volos, in the presence of the French Ambassador to Greece, Laurence Auer. The agreement aims to explore future collaboration in the field of submarine and surface ship projects.

This MoU marks a further step in strengthening an already established partnership, positioning METLEN as a strategic partner within Naval Group’s supply chain. Already benefiting from METLEN’s expertise regarding the manufacture of some key element for the FDI frigate on both Hellenic and French programs, Naval Group considers METLEN’s know-how in naval platforms as a key asset, which could lead to broader industrial cooperation across multiple naval platforms in the field of surface ships and submarines for the global markets.

This agreement highlights the shared ambition of both companies to support complex naval systems and contribute to a more resilient and competitive European defence ecosystem. It also reflects the steadily strenghtening Franco-Greek industrial ties, further reinforcing bilateral cooperation.
