According to Oceania Cruises, the Oceania Sonata is expected to be followed by three sister ships as part of a fleet expansion. The Oceania Arietta is scheduled to join the fleet in 2029, while two additional unnamed vessels are planned for 2032 and 2035.
Fincantieri noted that it previously constructed the Oceania Vista and Oceania Allura, which belong to a previous vessel series, at its Sestri Ponente shipyard. These were delivered in 2023 and 2025 respectively.
Fincantieri stated that the construction of the upcoming fleet will follow the technical standards established during its previous projects for the cruise line.
