The partners are setting out their next phase of cooperation with a destroyer contract already signed.1–2 On Sept. 24, OSN signed a contract with OCCAR, the Organisation Conjointe de Coopération en matière d’Armement, for two DDX destroyers for the Italian Navy. The contract is worth approximately €3.7 billion, including approximately €1.3 billion in options.2
The new letter sets guiding principles for cooperation, including strengthening OSN's industrial and commercial role and developing opportunities in domestic and international markets.1
OSN's work also includes FREMM EVO frigates under construction, Italian and international Legacy FREMM frigates, logistics support and four offshore patrol vessels.1
The DDX program shows how the partners' responsibilities meet inside OSN: Fincantieri designs and develops the naval platform as system integrator, while Leonardo designs and develops the combat system.2 The companies intend the agreement to further consolidate OSN's position in integrating naval platforms and combat systems.1–2
