The Impetuoso class were the first post-World War II destroyers built for the Italian Navy. The two ships were ordered in February 1950, entered service in 1958 and were retired in the early 1980s.^[1]

Design

The Impetuoso class hull design was based on the uncompleted World War II Comandanti Medaglie d'Oro-class destroyer.^[1] The class has a length of 127.6 m (419 ft) with length between perpendiculars of 123.4 m (405 ft), a beam of 13.2 m (43 ft), with a draught of 4.5 m (15 ft), and their displacement were 2,775 long tons (2,820 t) standard and 3,810 long tons (3,870 t) at full load. The ships was powered by two-shaft geared steam turbines with four Foster Wheeler boilers, with total power output of 65,000 shaft horsepower (48 MW). Impetuoso class has a maximum speed of 34 knots (63 km/h), with range of 3,000 nautical miles (5,600 km) while cruising at 16 knots (30 km/h).^[1] The ships has a complement of 315 personnel.

The class were armed with four 5-inch (127 mm)/38 caliber guns in two twin-gun turrets, 16 Bofors 40 mm/60 guns consisted of two quad-mounts and four twin-mounts, and one 305 mm Menon anti-submarine mortar. They were also armed with two fixed 533-millimetre (21 in) torpedo tubes, which was later replaced by two 12.75-inch (324 mm) triple-tubes with Mark 44 torpedoes.^[1] There was a proposed modernization program in the late 1960s for the ships to be rearmed with a single lightweight 5"/54 caliber Mark 45 gun forward and RIM-24 Tartar surface-to-air missile launcher in the aft.^[1]

The ships electronics and sensors consisted of SPS-6 air-search radar, SG-6B surface-search radar, SPG-25 and SPG-34 fire control radar, and SQS-11 search sonar, which was later replaced with SQS-4 sonar.^[1] As of 1980, Impetuoso was equipped with WLR-1 electronic support measure system with noise jammer, while Indomito appears to be not equipped with any electronic warfare system.^[1]

-The '''''Impetuoso'' class''' were the first post-[[World War II]] [[destroyer]]s built for the [[Marina Militare|Italian Navy]]. The hull design was based on the uncompleted ''Comandante''-class destroyers but American equipment (guns, radar, machinery) was used. A scheme to install guided missiles during a modernisation programme was proposed but not carried out. The two ships were ordered in 1952, entered service in 1957 and were retired in the early 1980s.
