History
The 12-inch/45 Mark 5 begins its story in the late 1890s. While smokeless powder, a revolution in firearms design was invented in 1884, the United States Navy didn't adopt it until the late 1890s after the Spanish American War. The first naval monitor battery to use these types of weapons was the 12 inch/40 calibre which would serve in Marks 3 and 4 on pre-dreadnought battleships of the United States in the early 19th century. The 12-inch/45 Mark 5 was developed as an improvement of this gun constructed at the US Navy Gun Factory in Washington DC with the specifications from the Bureau of Ordnance. The gun was made 5 calibres longer for improved muzzle velocity, range, and penetration power.
The 12"/45 Mark 5 gun entered service in 1906, which was an interesting period for warship development. The guns were first designed and used on the Connecticut-class of pre-dreadnought battleships and the later Mississippi-class. However, 1906 was the year that the ship HMS Dreadnought was launched, with a strictly big gun arrangement that rendered every other battleship obsolete overnight. The big gun arrangement had benefits that the US Navy was not blind to as they had been working on such a design since 1903 before the HMS Dreadnought was ordered by the Royal Navy in 1905. The result ended up becoming the South Carolina-class ships, the USS South Carolina and USS Michigan, which were ordered a month after HMS Dreadnought was launched, but boasted a superior center-fire arrangement for the armament (HMS Dreadnought had a port and starboard turret battery - the only dreadnought to do so). However, in the summer of 1916, the USS Michigan blew out one of her turrets which prompted an investigation into her sister South Carolina. The investigation concluded that the guns suffered from what is known as "copper choke", where the copper deposits from the driving bands on the bore of the rounds narrowed the bores and created a dangerous level of pressure when firing.
The South Carolina-class was soon followed by the Delaware-class ships USS Delaware and USS North Dakota. The United States would go on to produce a final class of dreadnoughts - the Florida-class ships USS Florida and USS Utah - but these would become the last of the ships to be armed with 12"/45 Mark 5 guns. The turn of the century marked a significant arms race among the various powers around the world, which had been intensified by the appearance of HMS Dreadnought in 1906 and escalated tension around the globe before World War I. At the end of the war, the victorious powers of the Entente banded together and signed the Washington Naval Treaty in 1922 which, among other stipulations, put a ten year hiatus or "holiday" as it was called on construction capital ships such as battleships from the five signatories. Then, in 1930, the London Naval Treaty was signed which required the Florida-class to remove their 12"/45 Mark 5s where they were transferred to the United States Army to serve as coastal defense batteries.
