The 5"/50 caliber gun (spoken "five-inch-fifty-caliber") was the first long barrel {{convert|5|in|0|adj=on|abbr=out}} gun of the United States Navy and was used in the secondary batteries of the early {{sclass-|Delaware|battleship|0}} dreadnought battleships, various protected cruisers, and scout cruisers. They were also refitted in the secondary batteries of the armored cruiser {{USS|New York|ACR-2|2}} and the {{sclass-|New Orleans|cruiser (1896)|0}} protected cruisers. They were later used on cargo ships, store ships and unclassified auxiliaries during World War II as well as in emergency coastal defense batteries.{{sfn|Navweaps|2008}}

Design

The Mark 5, Nos. 200 – 286, was a 50 caliber naval gun of a simplified construction by combining the breech piece along with the chase hoop into one long tube that was shrunk on from the muzzle. Mod 1 was a Mod 0 gun that was relined with a conical nickel-steel liner and an additional gun-steel chase hoop that extended to the muzzle that was secured by a nickel-steel locking ring. Mod 2, gun No. 280, had a slightly different liner with Mod 3, gun No. 245, was a Mod 0 gun with its gun-steel tube replaced with a nickel-steel tube with a gun-steel chase hoop added that extended all the way to the muzzle. The Mod 3 gun had a longer chase hoop and shorter jacket compare to Mods 1 and 2.{{sfn|Navweaps|2008}}{{sfn|Friedman|2011|p=184–185}}

The Mark 6, gun Nos. 293 – 356, was the bag-ammunition equivalent to the Mark 5 gun. Mod 0, Nos. 323 – 356, had a single jacket constructed of nickel-steel, that replaced the jacket, chase hoop and locking ring of the Mark 5. Mod 1, Nos. 293 – 306 and 308, was built of gun-steel with a chamber of a different design with some external differences to fit it onto different mountings. The Mod 2, Nos. 307 and 309 – 322, had the same chamber as the Mod 0 but was otherwise almost identical to the Mod 1.{{sfn|Navweaps|2008}}{{sfn|Friedman|2011|p=184–185}}
