The Thaon di Revel class (also known as PPA for 'Pattugliatore Polivalente d'Altura - Multipurpose Offshore Patrol Vessel') is a class of frigate built by Fincantieri for the Italian Navy.
It is planned to replace four Soldati-class light patrol frigates and eight Minerva-class corvettes between 2021 and 2035. As part of the 2014 Naval Law, a total of sixteen ships were planned and as of 2019 seven vessels have been financed with three more on option, not executed. European Patrol Corvette, a class of lighter ships built into an EU cooperation should complete the Italian Navy needs.
In March 2024, the Indonesian Ministry of Defense signed a contract with Fincantieri for the acquisition of two of the ships under construction for the Italian Navy. In June 2025, the Italian Navy ordered two ships to replace the ships sold to Indonesia, the ships are to be in light+ configuration.
