Orsa-class torpedo boat

Add article description

The Orsa class (sometimes called the Pegaso 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, specifically tailored for the escort and anti-submarine role, with greater endurance and a heavier depth charge armament but less powerful machinery and a lighter gun armament. Four were built, with two being lost during the Second World War. The surviving pair were rebuilt as anti-submarine frigates in the 1950s.
