Description
The Etna-class, RN Etna, project is a rank III Italian light cruiser with a battle rating of 4.7 (AB/RB/SB). It was introduced in Update "Ixwa Strike".
General info
Survivability and armour
The RN Etna is a unique ship, you cannot take an example from other ships. Its hull has many positive things but also several negative things. I start by saying Etna is a great ship at its battle rating, Its reinforcement is divided into 3 main thicknesses, starting with a 25mm front and followed by the side of the ship which is 60mm of armor and to finish we have the back of the ship with 35mm, all steel. It allows to block shots up to 152mm caliber with HE and SAP, APHE manage to pass but do not cause much damage, many fragments and debris are blocked by the remarkable protection against splinters of the ship (Hull 25mm steel).
And let's just say the hold is quite protected being located well below sea level. The ship is 146 meters long, 21 meters wide and 7.4 meters deep, the hull in general is very good, provide numbers for the protection it is narrow enough to allow the ship to be agile despite the length is not obvious, the draft is not very deep provide the number for the draft which further increases the maneuverability.
At the same rating we can find the Isuzu with 510 members, the Krasny Kavkaz with 878 sailors and the Bartolomeo Colleoni with 521. Obviously, the more crew members there are on the ship, the more difficult it will be to sink, because the more people are operational, the less time it will take to repair and extinguish the ship in case of an attack. The crew is mostly located in the center of the ship behind the anti-aircraft and auxiliary guns. The main turrets are not overly armored (20mm steel), they are quite uncovered, which is a disadvantage that is not obvious, also the rear turrets can only rotate up to 200 degrees which greatly limits the combat.
Let's see now how to sink this ship, a good shot under the front turret and the ship will explode in a big fire, you can also shoot right in the middle of the ship, right where most of the fuel is or if that's not enough aim under the two towers in the back of the ship and enjoy the explosion. To conclude we inform you that this ship has no torpedo armament.
Mobility
The maximum forward speed of the ship is 52km/h(32mph), while the maximum backward speed is -25km/h (15mph). The rudder is able to turn from one end to the other in 8 seconds, in case of danger the Etna is able to make a U-turn in 1 minute 32 seconds. You can see the very long hull that certainly does not help much to avoid enemy strikes and much less the torpedoes, Two Sulzer 12-ZAV-40S engines with a power of 11'600 Hp propel this 7000 ton ship at a maximum speed of 52km/h (32mph). The negative things instead are that being an old transport ship, it is quite large.

Armament
Primary armament
These weapons were designed to give about the same range as the 12 cm/50 (4.7") guns but with a lower muzzle velocity and with less dispersion. In fact, partly due to the wider barrel spacing used on the mountings, these guns had only a quarter of the dispersion of the 12 cm guns.
Used on the battleships Andrea Doria and Dulio as a secondary weapon and on the "Capitani Romani" class light cruisers as the main weapon. It had been intended to mount these weapons in the "Comandanti Medaglie d'Oro" and Etna classes in a new AA mounting but these ships were not completed
.
Etna's 135mm has a 7.5 seconds reload and at its rating is not bad at all, compared to the 14 seconds of the Bartholomew and Krasny Kavkaz. Its bullets are not the best, but they are respectable: the He have 1.8Kg(39.6 lbs) of explosive mass and a total penetration of 23mm, the ApHe come with 1.4Kg(30.8 lbs) and explosive and manage to penetrate 174mm of armor and to finish has the He-TF with the same amount of explosive as the He. Talking about the ballistics, the Etna is found with quite slow shots compared to the above mentioned ships. The He, the ApHe and the He-TF reach a speed of 825m/s, which does not help much in long distance fights.
For this ship we recommend the use of the ApHe as they are much more effective than the common He, although using the ApHe for all targets is not really indicated, for example against destroyers or ships with little armor He are perfect. Due to the low speed of the bullets, we do not recommend fighting beyond 10km (6.2 miles) as you could not do much damage.
Secondary armament
This medium-range AA gun was being developed by Ansaldo and Terni during World War II with some prototypes being completed, but it did not enter general service use. The loading equipment was electrically powered and included dual loading trays and a pantograph linkage rammer.
The Etna is equipped with 10 Ansaldo-Terni 65mm cannons that with their recharge of only 2 seconds do an important job for the ship, for example they keep away smaller ships that try to board you or they can be very effective against larger aircraft that do not yield with anti-aircraft defenses. The 65mm can be armed with 2 different types of projectiles, the He and the He-TF with both 450g (0.9 lbs) of explosive.
As previously mentioned the He's are very useful to annoy larger ships by creating fires or destroying modules, while the He-TF's are very intuitive to use, they are very effective against aircraft, especially larger ones.
Anti-aircraft armament
The Scotti-Isotta Fraschini 20/70 was an Italian cannon-gun. It was a multi-role weapon, which could be used as both an anti-aircraft and anti-tank function, available in both land and naval gun barrels.Development of the weapon began in 1928, by designer Alfredo Scotti,
The weapon employed the automatic recoil operation system, with fixed barrel and geometric block of the bolt removed by gas action.
The Etna has at its disposal as many as twenty-one 20mm anti-aircraft guns, of these twenty, six are positioned at the front of the ship. Just below the cockpit while the remaining fifteen are arranged evenly in the central part of the ship. These 20mm have 1500 rounds of ammunition and reload in 2.9 seconds. They are very effective against aircraft and can cause not inconsiderable damage to small ships. They have a maximum range of 3.5km (11482 ft) and a maximum effectiveness of 1.8km (5905 ft) against both air and surface targets.
Usage in battles
Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).
Pros and cons
Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in the bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

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. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the ship's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
