The USS Oklahoma (BB-37) was an American battleship laid down in 1912, launched in March 1914, and commissioned in the US Navy in May 1916. The length of the ship was 178 m, width - at the time of launching - 33 m, and full displacement - 32,200 tons. The top speed of the USS Oklahoma battleship was around 20-21 knots. The main armament was 10 356 mm guns in five turrets, two guns each, and the secondary armament was mainly 18 127 mm guns. USS Oklahoma was the second and final Nevada class battleship. Units of this type belonged to the so-called standard battleships, i.e. ships with similar combat values, dimensions and capabilities, although divided into different classes, which entered service with the US Navy in the period 1916-1923. Nevada-class battleships had good artillery armament, strong armor, but low top speed. USS Oklahoma (BB-37) took a limited part in World War I, entering European waters only in August 1918. In the interwar period, the battleship underwent a major reconstruction in 1927-1929. First of all, the boilers, bolts, armor and additional anti-torpedo bulkheads were replaced. However, the outdated drive system with steam piston machines was preserved. After the modernization, the USS Oklahoma operated primarily in the Pacific. The battleship was at Pearl Harbor at the time of the Japanese attack on December 7, 1941. As a result, the ship capsized and sank. In 1943, the shipwreck was lifted from the bottom, but finally a decision was made to abandon the renovation, and the excavated wreck was sold for scrap.
