The USS Oklahoma (BB-37) was the last of two Nevada class battleships of the US Navy. The Nevada class were the first to adopt the so-called all-or-nothing armour scheme, planning on shielding just the machinery and magazine spaces and leave the forward and after end of the ships unarmed so as to save weight and maximize armour thickness where it mattered. Launched in 1914 and commissioned two years later, Oklahoma differed from her sister by having old vertical triple expansion steam engines, as opposed to Nevada's new geared turbines, a novelty for the time. Being the geared turbine an untested system (having just introduced direct-drive ones 3 years earlier with the commissioning of USS Florida), it was preferred to revert to the old engines for the second battleship just in case something went wrong with the new systems. Also the Nevada class introduced oil-fired boilers into the US Navy, while older classes had coal-fired ones with some capable of oil spraying to have a more efficient combustion. During World War One Oklahoma became part of the Sixth Battle Squadron of the Grand Fleet alongside her sister Nevada, relieving the battleship Florida which returned to the States. In 1921 she joined the Pacific Fleet and there remained until December 7th, 1941. During the interwar period the ship was refitted several times after the Washington Naval Treaty forbade the construction of new battleships. During the attack on Pearl Harbor Oklahoma was moored at the battleship row alongside Maryland, and caught the brunt of an aerial torpedo attack as well as at least two torpedoes from a Japanese midget submarine which was then sunk. Those two torpedoes, being larger than the airborne ones, caused massive damage and led the ship to capsize, the only battleship to do so at Pearl Harbor (since the midget sub carrier only two torpedoes and hit only one target). The ship was righted and refloated in 1943, being decommisioned the following year and sold for scrap in 1946, being heavily damaged and surplus to requirements. In 1947 the hull foundered in a storm, while under tow from Hawaii to California.
