‎History: OK, I get it now, the advantage is in the range.

U12017485: /* History */ actually, if you replace it 3:1 and it's as effective as 2 guns, then it's a net loss in capability, lmao.

 The 3-inch Mk. 34 gun was developed by the United States Navy in response to Japanese Kamikaze attacks. Designed as an intermediate-calibre solution between the lighter 40 mm Bofors and the heavier 5-inch/38 (127 mm), the gun used a 76.2 mm, 50-calibre-long barrel with an electrically-driven autoloader. This allowed for a high rate of fire and tracking of fast-moving aircraft.
-The Mk. 34's single mount was similar in size to the quad 40 mm Bofors, and despite the heavier mass, it was possible to replace Bofors on a one-for-three basis. During the testing, it was found that a single 3"/50 was as effective as two 40 mm quad guns.
+The Mk. 34's single mount was similar in size to the quad 40 mm Bofors, and despite the heavier mass, it was possible to replace Bofors on a one-for-three basis. During testing, it was found that a single 3"/50 was as effective as two 40 mm quad guns, making it a net loss in capability at comparable ranges. However, the 3-inch gun could effectively engage targets at longer ranges, which became increasingly important with the advent of jet-powered aeroplanes.
 The initial prototype was ready by 1 September 1945, but with the end of the war, deployment was delayed until 1948. It became the weapon of choice on numerous US and allied ships from the late 1940s through to the 1980s. However, the history of the gun dates back to 1915, when the initial versions were introduced as dual-purpose weapons, undergoing modernisations and redesigns over the decades, culminating in the Mk. 34, which was the last significant upgrade for the gun.

-The '''3-inch/50 calibre Mark 34''' gun was developed by the US Navy during World War II as a response to the ineffectiveness of existing 20 mm and 40 mm anti-aircraft batteries against Japanese Kamikaze attacks. Designed as an upgrade of the 3"/50 calibre Mk. 22 gun, the Mk. 34 featured an autoloader that significantly improved its rate of fire, making it more effective against fast-moving aircraft. The gun entered service too late for widespread use in World War Two, it saw service from the late 1940s to the 1980s, replacing 40 mm Bofors on many US and allied ships. The Mark 34 was the single-mount variant, used notably on ships like [[USS Roanoke]] and other early post-WW2 vessels.

 In-game, '''{{PAGENAME}}''' is an exceptionally effective anti-aircraft gun, owing to her rapid-fire {{Annotation|HE-VT|High-explosive variable time fuse}} rounds and a very good vertical guidance of +85°. She can also be used against surface targets with either HE or AP rounds, though the armour-piercing ammunition suffers from a very small explosive filler.
