12 inch/50 Mk.7 cannons on the USS Wyoming

Description

Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available ammunition

Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

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

Boasting one of the longest continuous services of any large calibre weapon in the United States Navy's history, the 12 inch/50 Mark 7 was developed as an incremental improvement over the 12-inch/45 Mk.5. After the Florida-class was completed, the US Navy considered up-gunning to 14-inch guns as the Royal Navy had just adopted the 13.5 inch/45 Mark 5(H) guns. However, the Navy Bureau of Ordnance feared construction of a new calibre of naval cannon would delay the construction of the ships which became the Wyoming-class battleships, the USS Wyoming and USS Arkansas which entered service in 1912. To improve the capabilities of the 12 inch guns, the length was once again increased by five calibres to improve the range and penetration capabilities. The USS Wyoming and USS Arkansas were the only ships in the US Navy to use this cannon as the Navy would soon upgrade to 14-inch guns after they completed with the extra time given from using 12-inch guns on the Wyoming-class. Regardless, the US Navy would keep the guns in service until 1946 when the USS Arkansas was destroyed in a nuclear bomb test at Bikini Atoll (present day Marshall Islands) in 1946. The only other navy to use the 12"/50 Mark 7 is the Argentinian Navy. Disputes over the Patagonian and Beagle Channels with Chile and the River Plate with Brazil in the late 1800s and early 1900s sparked a dreadnought arms race on the continent of South America. Fore River Shipbuilding won a design bid for the Rivadavia-class dreadnoughts armed with similar twelve inch guns made by Bethlehem Steel Shipbuilding, which kept the Mark 7 in service until 1953.

Media

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