The Navigatori class were a group of Italian destroyers built in 1928-29. These ships were named after Italian explorers. They fought in World War II. Just one vessel, the Nicoloso Da Recco, survived the conflict.
These ships were built for the Regia Marina as a reply to the large contre-torpilleurs of the Jaguar and Guepard classes built for the French Navy. These ships were significantly larger than other contemporary Italian destroyers and were initially classed as esploratori or scouts. They were re-rated as destroyers in 1938.
The main armament was a new model 120 mm gun (Ansaldo 1926 pattern, 50 calibre) in 3 twin turrets which allowed for 45° elevation. The torpedo launchers consisted of two triple banks, each unusually comprising two 533 mm (21 in) separated by one 450 mm (18 in). Two rangefinder positions were provided; one above the bridge and one in the after superstructure.
Unit machinery was used comprising 4 boilers in two widely spaced boiler rooms and two turbine rooms. The forward unit drove the port shaft and the aft unit drove the starboard shaft. Trials were run light and with overloaded machinery leading to speeds of up to 43.5 knots which were not achievable under service conditions.
The ships were fast, but were found to lack stability and were rebuilt with a clipper bow, increased beam and reduced superstructure in the late 1930s.
During the war the torpedoes were replaced by triple 21 inch tubes and extra AA guns were added.
