Description

The Impetuoso-class of destroyers are the first Italian destroyers built after World War II. The ship uses a modified hull design of the World War II-era Comandante Margottini-class as a basis, albeit incorporating design elements from the American Gearing-class destroyer, namely various surplus armaments from the US Navy and fire control system along with similar compartment layouts, giving the ship better survivability and operational range to suit the need of the Marina Militare at the cost of mobility.

Introduced in Update "Sons of Attila", the Impetuoso could be considered a toned down version of the American Gearing-class, primarily due to her armaments of four 5-inch dual-purpose cannons in two fully traversable dual turrets. Although the Impetuoso offers more consistent firepower improvements compared to the wartime Italian destroyers, she does still have some shortcoming stemming from her origin of a modified design that holds her back, in particular her (lack of) protection for critical modules, so care must be taken to minimize their exposure.

The Impetuoso features a spread out compartmented layout that distributes modules and crew quarters evenly along the fairly large hull of the ship. This allows the ship to contain the damage from concentrated fire better than its peers. The large crew count of 335 distributed evenly on the ship also allows the Impetuoso to stay afloat longer than other destroyers at its BR.

However, the use of hull space on the Impetuoso as armour also leaves the fatal flaws in the form of unprotected critical modules. Due to an even distribution of compartments, this left the Italian engineers no other place to put the auxiliary magazine but the questionable midship position between the engines. This auxiliary magazine can be easily detonated from the broadside angles, potentially causing chain detonation with the torpedoes that are stored directly above it, which may result in uncontrollable flood damage. The rear main magazine of the stern turret is also equally vulnerable, as it sits barely below the waterline. Because of this, angling is a must in the Impetuoso to minimize the exposure of these weakspots.

Mobility

Speedforward / back

AB79 / 33 km/h

RB65 / 27 km/h

While the Impetuoso features respectable top speed of 79 (AB)/65 (RB) km/h, due to her large hull and displacement, the ship is noticeably more sluggish to manoeuvre than its peer. This is especially apparent during acceleration/deceleration process, as the ship takes longer to shift between each speed and to traverse around.

Armament

Primary armament

2 х Turret2 x 5 inch/38 Mk.12 cannon, mount Mk.38

Ammunition720 rounds

Vertical guidance-15° / 85°

The Impetuoso features 4 x 5-inch (127 mm) Mk.12 cannons as the main armaments. The guns are mounted in enclosed twin turrets with one each on the bow and stern. The guns have an impressive fire rate of 22 rounds per minute (~2.7-second reload) with 25-round first stage ammo racks, and 15 rounds per minute (4-second reload) after depleting the ready racks. The turrets are fully traversable with good handling, thus allowing the Impetuoso to effectively engaging surface and aerial targets on both sides of the ship. At her BR, this gun armament is more than capable of quickly eliminating opponents, and provide consistent firepower against any early cruisers that she might have to face in uptiers.

Being standard-issued guns of the US Navy, the Impetuoso also has access to the standard US destroyer ammunition: a basic and potent HE shell with 3.2 kg of TNT equivalent filler, an HE-VT shell with the same characteristics as the HE shell but with a proximity fuse for use against aircraft, a "Common" SAP shell with respectable penetration and filler, and a "Special Common" SAP shell which has improved penetration in exchange for somewhat reduced filler. As with any American destroyer, getting the SAP shells should be your priority, as they will allow you to deal critical internal damage to enemy ships and target their magazines. Due to having less penetration but slightly more filler, the "Common" shell is somewhat more effective at dealing with destroyers compared to the "Special Common" shell, but will lose its effectiveness against cruisers at longer ranges. It should be noted that both SAP shells have almost exactly the same ballistics and have the exact same fuse delay, meaning that the "Special Common" shell's post-penetration travel distance will not be any longer than the "Common" shell. You can choose to bring only one type of SAP shell for simplicity, or bring both types and switch between them according to your target.

For anti-air defense, the Impetuoso features 16 x Bofors autocannons mounted in four dual mounts and two quadruple mounts placed along the port and starboard sides of the midship section. The Bofors provide excellent anti-air firepower at short-to-medium ranges and offers good resistance against small PT boats, though due to the placement of the guns, it has a large blindspot around the bow of the ship at close range, thus leaving the ship vulnerable from attacks coming at this angle.

Meanwhile, each Bofors mounts is equipped with a search-and-tracking air radar with decent scan rate. This works well in conjunction with the main guns' HE-VT rounds to take down enemy aircraft at longer ranges.

• Virtually no armour protecting the critical components, especially ammo racks on the midship and stern
• Has only four torpedoes mounted in fixed tubes
• Placement of dedicated AA armaments leaves several blindspots around the ship at close range

History

Describe the history of the creation and combat usage of the ship in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the ship and adding a block "/History" (example: https://wiki.warthunder.com/(Ship-name)/History) and add a link to it here using the main template.
