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, and construction of two replacement units is expected in the future.
