Spica-class torpedo boat

The Spica-class was a class of torpedo boats of the Regia Marina (Royal Italian Navy) during World War II.

Called torpedo boats due to their smaller displacement, the Spica-class had armament similar to destroyers (influenced by the Maestrale-class destroyer) and were intended for anti-submarine operations but also had to fight aircraft and surface ships.

Twenty-three vessels were lost during the war, two had been sold to the Swedish Navy in 1940 and were called destroyers until 1953, and then renamed to corvettes.

This weapon had a shorter range and a smaller warhead than the 533 mm (21 in) torpedoes in use on destroyers.
