The 120 millimeter/45-calibers O.T.O.

A French design, the guns were originally used to arm auxiliary craft during World War I. Licensed production began with Vickers-Terni in 1924 leading the 120 mm/45 Vickers-Terni Mod. 1924 used on the ''Sauro''-class destroyers. These new guns offered more firepower compared to the prior WWI-era destroyers built with 102mm guns and 102mm as the standard caliber for future destroyer designs. These guns used a 17-pound smokeless powder charge to launch a 51-pound projectile at 2,800 feet per second and a range of 9.6 miles. Its maximum elevation was 33 degrees and it used a 16.6 twin mount to increase dispersion. In 1926, The Terni Steelworks formally merged with ''Cantiere navale fratielli Orlando'' and ''Canitieri navali Odero'' to form O.T.O. The designation was thus changed to The 120 mm/45 O.T.O. model 1926 which was used to arm the later [[Turbine (Family)|''Turbine''-class]] destroyers and rearm their ''Sella''-class destroyers.

All ships of the ''Turbine''-class with the majority serving in Italian service. However, ''RN Euro'' was still in service by the time of the Armistice of Cassibile in September 1943 and served in the Dodecanes Campaign before being sunk by [[Ju 87 (Family)|Ju 87 ''Stuka'']] air raid in October 1943 off the coast of Leros Island, Greece. The namesake ship [[RN Turbine|''RN Turbine'']] was seized by the ''Kriegsmarine'' (German War Navy) in 1944 and the Aegean Sea as a torpedo before suffering severe damage from an explosion at Porto Lago, Greece, and then being sunk by a US air strike while being repaired at Salamis Island. The ''Sella''-class similarly would change hands a few times during the war and two survived the conflict as a result. The namesake ''RN Quintino Sella'' served in the Italian Co-Belligerent Navy after the Armistice and was sunk on September 11th that year by a German E-boat while in the Adriatic Sea. ''Francesco Crispi'' was seized by the Germans like ''Turbine'' and, under the new name ''TA15'', she served until being sunk by an air attack in the Aegean on March 8th, 1944. The two ships to survive the war were the ''Bettino Ricasoli'' and ''Giovanni Nicotera''. These ships were sold to the Swedish in 1940 and the nation's neutrality meant the newly rechristened ''HSwMS Puke'' and ''HSwMS Psilander'' had mostly uneventful careers before they decommissioned in 1947 and were scrapped two years later.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

History

The 120-millimetre/45-calibre O.T.O. Mod. 1926 is a licensed version of the French 120 mm/45 Canet-Schneider-Armstrong mod.1918 naval gun. A French design, the guns were originally used to arm auxiliary craft during World War I. Licensed production began with Vickers-Terni in 1924 leading to the 120 mm/45 Vickers-Terni Mod. 1924 used on the Sauro-class destroyers. These new guns offered more firepower compared to the prior WWI-era destroyers built with 102 mm guns and 120 mm became the standard caliber for future destroyer designs. These guns used a 17-pound smokeless powder charge to launch a 51-pound projectile at 2,800 feet per second and a range of 9.6 miles. Its maximum elevation was 33 degrees and it used a 16.6" twin mount to increase dispersion. In 1926, Terni Steelworks formally merged with Cantiere navale fratielli Orlando and Canitieri navali Odero to form O.T.O. The designation was thus changed to the 120 mm/45 O.T.O. model 1926 which was used to arm the later Turbine-class destroyers and rearm their Sella-class destroyers.

Media

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