The Orsa class were a group of large torpedo boats or destroyer escorts built for the Italian Navy in the late 1930s. They were an enlarged version of the Spica-class torpedo boat, with more endurance and a greater depth charge load but less powerful machinery and a lighter gun armament. The surviving pair were rebuilt as anti-submarine frigates in the 1950s.
