Impetuoso
Contents
Description
The Impetuoso-class of destroyers are the first destroyers built in Italy after World War II. The design uses a modified hull of the World War II-era Comandanti Medaglie d'Oro-class as a basis and incorporates design elements from the American Gearing-class destroyer, including various surplus American armaments and fire control systems along with similar compartment layouts, giving the ship better versatility and operational range to suit the needs of the Marina Militare at the cost of mobility.
Introduced in Update "Sons of Attila", the Impetuoso can be considered a toned down version of the American Gearing-class, primarily due to her armament of four 5-inch dual-purpose guns in two fully traversable dual turrets. Although the Impetuoso offers more consistent firepower compared to the wartime Italian destroyers, she does still have some shortcomings stemming from her origin as a modified design, in particular her (lack of) protection for critical modules, so care must be taken to minimize their exposure.
General info
Survivability and armour
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
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
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.

Secondary armament
For anti-air defense, the Impetuoso features 16 x 40mm Bofors autocannons mounted in four dual mounts and two quadruple mounts placed along the port and starboard sides of the midship section. The Bofors guns provide excellent anti-air firepower at short-to-medium ranges and offer good resistance against small PT boats, though due to the placement of the guns, there is a large blindspot towards the bow of the ship at close range, thus leaving the ship vulnerable from attacks coming from 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.
