The Spica-class was a class of torpedo boats of the Regia Marina (Royal Italian Navy) during World War II. These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers. Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy.
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.
