The Comandanti Medaglie d'Oro class were a group of 20

laid down by the time of the Italian armistice in September 1943 and all but one of those ships which had not yet been laid down were cancelled. Of those that had been laid down, none had been launched by that time and all were subsequently scrapped

Design and description

By mid-1941, the Ministero della Marina (Navy Ministry) had concluded that its existing destroyer building program was insufficient to replace its losses and authorized a new design that would incorporate the war experience gained thus far. The anti-aircraft armament of the preceding

The Comandanti Medaglie d'Oro-class ships had a

deep load. Their crew was intended to consist of 15 officers and 262 enlisted men.[3]

The Comandanti Medaglie d'Oros were powered by two

kW) and a speed of 35 knots (65 km/h; 40 mph) in service.[4] The ships carried a maximum of 740 metric tons (730 long tons) of fuel oil to give them an estimated range of 3,300 nautical miles (6,100 km; 3,800 mi) at a speed of 20 knots (37 km/h; 23 mph).[3]

The propulsion machinery for the fourth ship of the third series, Comandante Esposito, was going to be rearranged to improve the survivability of the Comandanti Medaglie d'Oro class as the existing layout meant that a single hit could disable all of the boilers and immobilize the ship. At the cost of some additional length, the Italians intended to adopt the unit system of machinery in which each turbine was paired with two boilers, each in their own compartment and using their own funnel, so that one "unit" of machinery could still work if the other was knocked out.[5]

Armament and sensors

Builder's model of the second-series ships

Their main battery would have consisted of 45-caliber Cannone da 135/45 OTO Mod. 1937 guns, the number of which and distribution varied between the ships. The first series of eight ships would have had four single shielded mounts, one superfiring pair fore and aft of the superstructure. The second and third series would have had an extra single mount at the aft end of the superstructure.[6] The guns fired 32.7-kilogram (72 lb) shells at a muzzle velocity of 825 meters per second (2,710 ft/s) to a range of 19,600 meters (21,400 yd) at their maximum elevation of 45 degrees.[7]

The secondary armament of the first series of the Comandanti Medaglie d'Oro-class ships was provided by a dozen single mounts for 54-caliber

Nighttime illumination was to be provided by a pair of multi-barrel rocket launchers, one mount on each side of the bridge.[6]

The ships would have been equipped with six 533-millimeter (21 in)

amidships.[3] Possessing a 270-kilogram (595 lb) warhead, the torpedo had ranges of 4,000 meters (4,374 yd) at 46 knots (85 km/h; 53 mph) and 12,000 meters (13,123 yd) at 29 knots (54 km/h; 33 mph).[9] The Italians intended to provide them with a sonar system of an unknown type for anti-submarine work. They would have been fitted with a pair of depth charge throwers and 64 depth charges.[3] The Comandanti Medaglie d'Oros would have been able carry 52 mines as well.[10]

The first-series ships would have been fitted with a single RM-2 gunnery

search radar. The second series were intended to incorporate another director amidships between the torpedo tubes to control the aft guns.[6]

Ships

The ships were named after

captains who were posthumous recipients of the Medaglie d'Oro (Gold Medal of Military Valor). The first series of eight ships was ordered on 27 September 1941 and the second series of eight ships was ordered a year later. Four ships of the third series were ordered on 7 October 1942 and another four were authorized. These last four were cancelled in April 1943 in favor of eight Ariete-class torpedo boats. Allied bombing in 1943 damaged the facilities at the Livorno shipyard and caused two of the destroyers under construction there, Comandante Borsini and Comandante Fontana, to be reassigned to the second series while Comandante Giorgis and Comandante Giobbe were transferred to the first series. Comandante Margottini was the only ship to be launched as the Germans did it in early 1944 to make the slipway available for new construction. By August 1943 material shortages had significantly slowed the pace of building so that the launching of the third-series ships was delayed until early 1946. By this date virtually all of the material for the first series and, half of the material for the second series had been allocated. Nothing for the third ships of the third series had been ordered and they were cancelled after the Armistice.[11]
