USS Oklahoma (BB-37) was a standard battleship in the United States Navy and the second ship in the Nevada class. She was laid down on October 26, 1912; launched on March 23, 1914; and commissioned on May 2, 1916. She differed from her sister ship in that she had an outdated propulsion system with steam engines instead of turbines. In 1917, the battleship was modernized. In 1918, she was assigned to Battleship Division Six, along with her sister ship, USS Nevada. The two ships were sent to the shores of Europe. The division was based in County Cork, Ireland, and was tasked with protecting American convoys. However, the division was only called upon to do so once. After the war, the unit escorted the presidential liner to South America and then to Europe. In July 1919, Oklahoma returned to New York for modernization and repairs. Afterward, she was assigned to the Atlantic Fleet. She later participated in joint exercises with the Pacific Fleet. After the 1922 naval reform, she was assigned to the Scouting Fleet on the West Coast. In 1936, Oklahoma participated in the rescue of American citizens and refugees from Bilbao. On September 11, the battleship returned to Norfolk before moving to the West Coast. On December 29, 1937, the Oklahoma became homeported at Pearl Harbor.
On December 7, 1941, USS Oklahoma was moored alongside other battleships at Pearl Harbor. During the Japanese air raid, the ship was hit by three torpedoes in her underwater section. The first torpedo only damaged the torpedo defenses, but a subsequent hit in the same area caused severe flooding. The ship initially listed to port but capsized in less than 12 minutes after receiving two more torpedo hits and settled on her keel. Four hundred twenty-nine sailors and officers perished in the attack. The operation to raise the battleship began in early 1942. On June 16, 1943, the ship was raised to an even keel. In December, she was towed to the dry dock at Pearl Harbor, where most of her systems were removed and her hull was repaired. However, the Navy deemed the ship unfit for repair. In 1944, she was decommissioned, and in 1946, she was sold for scrap. While being towed into San Francisco Bay, the battleship's hull began to list, causing her to sink and nearly taking both tugboats with her. The exact location of the hull remains unknown.
USS Oklahoma was introduced as a reward for the 2026 "Pacific Pearl" event. The battleship is depicted in her 1926 modernization. She has a very low maximum speed, poor maneuverability, a long reload time for her main battery guns, and a very weak anti-aircraft battery. However, her armor is strong enough to engage her opponents at medium and close range and armor-piercing shells are very good in destroying dreadnoughts.
