RN Bolzano

Description

The RN Bolzano, laid down on 11 June 1930, launched on 31 August 1932, completed and delivered on 19 August 1933, was a heavy cruiser based on the hull of the Trento class. RN Bolzano had several modifications and was practically a mixture of the Zara and Trento classes, featuring the powerplants and 203 mm/53 Ansaldo mod.1927 cannons of the Zara class with reduced protection on the main turrets, improved watertighting compartmentation compared to the Trento class, and other minor modifications. However, she proved to be weaker than the Zara class and therefore an almost useless upgrade. Upon entering service, RN Bolzano joined the naval forces deployed in the Mediterranean. During World War II, she participated in the Battle of Punta Stilo, in the interception of Allied ships involved in the British Operation Mincemeat, and in the Battle of Mid-August, during which she was severely damaged by a torpedo from the submarine HMS Unbroken. She would remain in the port of La Spezia and be abandoned after the armistice. On 22 June 1944, she was attacked by British and Italian assault craft, and only in April 1945 was she found, sunk and capsized by the American 5th Army and the first Italian Co-Belligerent units. She was later recovered and scrapped in 1949.

Introduced in Update "Alpha Strike", RN Bolzano mixes features from RN Trento and RN Zara. The main armament is improved thanks to Zara's 203 mm cannons with a better reload, but the anti-air armament and armour protection remain mediocre. She has good manoeuvrability and speed, so it is recommended to play around hard cover such as islands to maximise survivability.

General info

Survivability and armour

Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

Mobility

Write about the ship's mobility. Evaluate its power and manoeuvrability, rudder rerouting speed, stopping speed at full tilt, with its maximum forward and reverse speed.

Armament

Primary armament

Main article: 203 mm/53 Ansaldo mod.1927 (203 mm)

Provide information about the characteristics of the primary armament. Evaluate their efficacy in battle based on their reload speed, ballistics and the capacity of their shells. Add a link to the main article about the weapon: {{main|Weapon name (calibre)}}. Broadly describe the ammunition available for the primary armament, and provide recommendations on how to use it and which ammunition to choose.

Secondary armament

Main article: 100 mm/47 O.T.O. Mod. 1928 (100 mm)

Some ships are fitted with weapons of various calibres. Secondary armaments are defined as weapons chosen with the control Select secondary weapon. Evaluate the secondary armaments and give advice on how to use them. Describe the ammunition available for the secondary armament. Provide recommendations on how to use them and which ammunition to choose. Remember that any anti-air armament, even heavy calibre weapons, belong in the next section. If there is no secondary armament, remove this section.

An important part of the ship's armament responsible for air defence. Anti-aircraft armament is defined by the weapon chosen with the control Select anti-aircraft weapons. Talk about the ship's anti-air cannons and machine guns, the number of guns and their positions, their effective range, and about their overall effectiveness – including against surface targets. If there are no anti-aircraft armaments, remove this section.

Additional armament

Main article: S.I. 270/533,4X7,2 Tipo I (533 mm)

Describe the available additional armaments of the ship: depth charges, mines, torpedoes. Talk about their positions, available ammunition and launch features such as dead zones of torpedoes. If there is no additional armament, remove this section.

Scout plane

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).

Bolzano was ordered in the late 1920s as part of a larger Italian naval rearmament program. Unlike the Trento and Zara classes however, Bolzano represented a one-off construction combining design aspects of both the older Trento as well as the more advanced Zara class. After its commissioning in 1933, Bolzano had a rather uneventful initial interwar service. Throughout World War II however, Bolzano played a significant role in various naval engagements, including the Battle of Calabria and the Battle of Cape Spartivento. During these engagements, Bolzano's design proved its worth after surviving deadly torpedo attacks on several occasions. In 1943 however, with Italy's surrender looming and the threat of German occupation imminent, Bolzano was scuttled by her own crew in the port of La Spezia to prevent her capture.

Excellent additions to the article would be video guides, screenshots from the game, and photos.
