USS Oklahoma (BB-37)

USS Oklahoma (BB-37), the only ship of the United States Navy to ever be named for the 46th state, was a World War I-era battleship and the second of two ships in her class; her sister ship was USS Nevada (BB-36). She, along with her sister, were the first two U.S. warships to use oil fuel instead of coal.

The Oklahoma, commissioned in 1916, served in World War I as a member of BatDiv 6, protecting Allied convoys on their way across the Atlantic. After the war, she served in both the United States Battle Fleet and Scouting Fleet. Oklahoma was modernized between 1927 and 1929. In 1936, she rescued American citizens and refugees from the Spanish Civil War. On returning to the West coast in August of the same year, Oklahoma spent the rest of her service in the Pacific.

On 7 December 1941, Oklahoma was sunk by several bombs and torpedoes during the Japanese attack on Pearl Harbor. A total of 429 crew died when she capsized in Battleship Row. In 1943 Oklahoma was righted and salvaged. However, unlike most of the other battleships that were recovered following Pearl Harbor, the Oklahoma was too damaged to return to duty. She was eventually stripped of her remaining armaments and superstructure before being sold for scrap in 1946. She sank in a storm while being towed from Oahu in Hawaii to a breakers yard in San Francisco Bay in 1947.

Design
Oklahoma was the second of two Nevada-class battleships. Both were ordered in a naval appropriation act on 4 March 1911. She was to be the latest in a series of 22 battleships and seven armored cruisers ordered by the United States Navy between 1900 and 1911.

The Nevada-class were the first of the US Navy's Standard type battleships, of which 12 were completed by 1923. With these ships, the Navy created a fleet of modern battleships similar in long-range gunnery, speed, turning radius, and protection. However, significant improvements were made in the Standard type ships as naval technology progressed. The main innovations were triple turrets and all-or-nothing protection. The triple turrets reduced the length of the ship that needed protection by placing 10 guns in four turrets instead of five, thus allowing thicker armor. The Nevadas were also the first US battleships with oil-fired instead of coal-fired boilers, oil having more recoverable energy per ton than coal, thus increasing the ships' range. Oklahoma differed from Nevada in being fitted with triple expansion steam engines, a much older design than Nevada's new geared turbines. Some earlier battleships had been fitted with direct drive turbines, which had poor fuel economy and thus reduced range compared with triple expansion. The goal was to compete the new geared machinery against the proven reciprocating machinery to determine which was more economical. The geared turbines won the race and were fitted in most subsequent US battleships, except those with turbo-electric propulsion.

As constructed, she had a standard displacement of 27,500 t and a full-load displacement of 28,400 t. She was 583 ft in length overall, 575 ft at the waterline, and had a beam of 95 ft and a draft of 28 ft.

She was powered by 12 oil-fired Babcock and Wilcox boilers driving two dual-acting triple expansion reciprocating steam engines, with 24,800 indicated horsepower, with a maximum speed of 20.5 knots. She had a designed range of 8,000 nmi at 10 knots.

As-built armor on Oklahoma consisted of belt armor from 13.5 inches (343 mm) to 8 inches (203 mm) thick. Deck armor was 3 in thick with a second 1.5 inch (38 mm) deck, and turret armor was 18 inches (457 mm) or 16 inches (406 mm) on the face, 5 inches (127 mm) on the top, 10 inches (254 mm) on the sides, and 9 inches (228 mm) on the rear. Armor on her barbettes was 13.5 inches (343 mm). Her conning tower was protected by 16 inches (406 mm) of armor, with 8 inches (203 mm) of armor on its roof.

Her armament consisted of ten 14 inch (356 mm) 45 cal guns, arranged in two triple and two twin mounts designated A, B, X, and Y. As built, she also carried 21 5 inch (127 mm) 51 cal guns, primarily for defense against destroyers and torpedo boats. She also had two (some references say 4) 21 inch (533 mm) torpedo tubes for the Bliss-Leavitt Mark 3 torpedo. Her crew consisted of 864 officers and enlisted men.

Construction
Her keel was laid down on 26 October 1911 by the New York Shipbuilding Corporation of Camden, New Jersey, who bid $5,926,000 to construct the ship. By 12 December 1912, she was 11.2 percent complete, and by 13 July 1913 she was at 33 percent. She was launched on 23 March 1914, being sponsored by Miss Lorena J. Cruce, daughter of Governor of Oklahoma Lee Cruce. The launch was preceded by an invocation given by Elijah Embree Hoss—the first for an American warship in half a century—and was attended by various dignitaries from Oklahoma and the federal government. The battleship was subsequently moved to a dock near the new Argentine battleship ARA Moreno and Chinese cruiser Fei Hung (soon to be the Greek GREEK CRUISER Elli) for fitting-out. On the night of 19 July 1915, large fires were discovered underneath the fore main battery turret, the third to flare up on an American battleship in less than a month. However, by the 22nd, the Navy believed that the Oklahoma fire had been caused by "defective insulation" or a mistake made by a dockyard worker. The fire delayed the completion of the battleship such that Nevada was able to conduct her sea trials and be commissioned before Oklahoma. On 23 October 1915, she was 98.1 percent complete. She was commissioned at Philadelphia, Pennsylvania, on 2 May 1916 with Captain Roger Welles in command.

Early service and World War I


Following commissioning, the ship remained along the East Coast of the United States primarily visiting various Navy yards. She was initially not able to join the Battleship Division Nine task force sent to support the Grand Fleet in the North Sea during World War I due to a lack of oil available there. In 1917, she underwent a refit and two 3"/50 caliber guns were installed forward of the mainmast for anti aircraft defense, and nine of the 5"/51 caliber guns were removed or repositioned. While conditions on the ship were cramped, the sailors on the ship had many advantages for education available to them. They also spend their time on athletic competitions, including boxing, wrestling and rowing competitions with the crews of the battleship USS Texas (BB-35) and the tug USS Ontario (AT-13). The camaraderie built from these small competitions led to fleet-wide establishment of many athletic teams pitting crews against one another for morale by the 1930s.

On 13 August 1918, Oklahoma was assigned to Battleship Division Six under the command of Rear Admiral Thomas S. Rodgers, and departed for Europe alongside USS Nevada (BB-36). On 23 August they rendezvoused with destroyers USS Balch (DD-50), USS Conyngham (DD-58), USS Downes (DD-45), USS Kimberly (DD-80), USS Allen (DD-66), and USS Sampson (DD-63), 275 mi west of Ireland, before steaming for Berehaven Harbor, where they waited for 18 days before battleship USS Utah (BB-31) arrived. The division remained at anchor, tasked to protect American convoys coming into the area, but was only called out of the harbor once in 80 days. On 14 October 1918, while under command of Charles B. McVay, Jr., she escorted troop ships into port at the United Kingdom, returning on 16 October. For the rest of the time, the ship conducted drills at anchor or in nearby Bantry Bay. To pass the time, the crews played football, and competitive sailing. Oklahoma suffered six casualties between 21 October and 2 November to the 1918 flu pandemic. Oklahoma remained off Berehaven until the end of the war on 11 November 1918. Shortly thereafter, several Oklahoma crewmembers were involved in a series of fights with members of the Sinn Féin group, forcing the ship's commander to apologize and financially compensate two town mayors.

Interwar period
Oklahoma left for Portland, England on 26 November, joined there by USS Arizona (BB-39) on 30 November and Nevada, 4 December, and Battleship Division Nine's ships shortly after. The ships were assigned as a convoy escort for the SS George Washington, carrying President Woodrow Wilson, and arrived with that ship in France several days later. She departed 14 December for New York City, and then spent early 1919 conducting winter battle drills off the coast of Cuba. On 15 June 1919, she returned to Brest, escorting Wilson on a second trip, and returned to New York on 8 July A part of the Atlantic Fleet for the next two years, Oklahoma was overhauled and her crew trained. The secondary battery was reduced from 20 to 12 5 in/51 cal guns in 1918. Early in 1921, she voyaged to South America's west coast for combined exercises with the Pacific Fleet, and returned later that year for the Peruvian Centennial.

She then joined the Pacific Fleet and in 1925 began a high-profile training cruise with several other battleships. They left San Francisco on 15 April 1925, arrived in Hawaii on 27 April, where they conducted war games. They left for Samoa on 1 July, crossing the equator on 6 July. On 27 July, they arrived in Australia and conducted a number of exercises there, before spending time at New Zealand, returning to the United States later that year. In early 1927, she transited the Panama Canal and moved to join the Scouting Fleet. In November 1927 she entered Philadelphia Navy Yard for an extensive overhaul. She was modernized by addition of eight 5 in/25 cal guns and her turrets' maximum elevation was raised from 15 to 30 degrees. An aircraft catapult was installed atop turret 'Y'. She was also substantially up-armored between September 1927 and July 1929, where anti-torpedo bulges were added, as well as an additional 2 in of steel on her armor deck. The overhaul increased her beam to 108 ft, the widest in the U.S. Navy, and reduced her speed to 19.68 knots.

Oklahoma rejoined the Scouting Fleet for exercises in the Caribbean, then returned to the west coast in June 1930 for fleet operations through spring 1936. That summer, she carried midshipmen on a European training cruise, visiting northern ports. The cruise was interrupted with the outbreak of civil war in Spain, as Oklahoma sped to Bilbao, arriving on 24 July 1936 to rescue American citizens and other refugees whom she carried to Gibraltar and French ports. She returned to Norfolk on 11 September, and to the West Coast 24 October.

The Pacific Fleet operations of Oklahoma during the next four years included joint operations with the Army and the training of reservists.

Pre-war Pearl Harbor history
She was based at Pearl Harbor from 29 December 1937 for patrols and exercises, and only twice returned to the mainland, once to have anti-aircraft guns and armor added to her superstructure at Puget Sound Navy Yard in early February 1941 and once to have armor replaced at San Pedro in mid August of the same year. En route on 22 August, a severe storm hit Oklahoma, and one man was swept overboard along with three men injured. The next morning, a broken outboard coupling on the starboard deck forced the ship to halt, assess the damage, and move to San Francisco, the closest navy yard with an adequate drydock. She would remain in drydock for two months.

During the attack on Pearl Harbor


Based at Pearl Harbor from 29 December 1937 for patrols and exercises, Oklahoma was moored in Battleship Row on 7 December 1941, when the Japanese attacked. Outboard alongside USS Maryland (BB-46), Oklahoma took three torpedo hits almost immediately after the first Japanese bombs fell. As she began to capsize, two more torpedoes struck home, and her men were strafed as they abandoned ship. Within 12 minutes after the attack began, she had rolled over until halted by her masts touching bottom, her starboard side above water, and a part of her keel exposed.

Many of her crew, however, remained in the fight, clambering aboard Maryland to help serve her anti-aircraft batteries. Four hundred and twenty-nine of her officers and enlisted men were killed or missing. One of those killed—Father Aloysius Schmitt—was the first American chaplain of any faith to die in World War II. Thirty-two others were wounded, and many were trapped within the capsized hull. Julio DeCastro, a Hawaiian civilian yard worker, organized a team that saved 32 Oklahoma sailors.

Some of those who died later had ships named after them such as Ensign John England for whom USS England (DE-635) and USS England (DLG-22) are named. The USS Austin (DE-15) was named for Chief Carpenter John Arnold Austin who was also posthumously awarded the Navy Cross for his actions during the attack. Three Medals of Honor, three Navy and Marine Corps Medals and one Navy Cross were awarded to sailors who served on board the Oklahoma during the attack.

Salvage
The job of salvaging the Oklahoma commenced on 15 July 1942 under the immediate command of Navy Captain F.H. Whitaker and a team from the Pearl Harbor Naval Shipyard.

Preparations for righting the overturned hull took under eight months to complete. Twenty one derricks were attached to the upturned hull; each carried high-tensile steel cables that were connected to hydraulic winching machines ashore. The righting (parbuckling) operation began on 8 March and was completed by 16 June 1943. Teams of naval specialists then entered the previously submerged ship to remove any additional human remains. Cofferdams were then placed around the hull to allow basic repairs to be undertaken so that the ship could be refloated; this work was completed by November. On 28 December, Oklahoma was towed into dry dock No. 2 at the Pearl Harbor Naval Shipyard. Once in the dock, her main guns, machinery, and remaining ammunition and stores were removed. The severest structural damage on the hull was also repaired to make the ship watertight.

After several months in the dry dock, the Oklahoma was moved and moored elsewhere in Pearl Harbor. Although there had been initial plans to salvage the ship, Oklahoma was decommissioned on 1 September 1944. All remaining armaments and superstructure were then removed. On 5 December 1946, Oklahoma was sold to Moore Drydock Company of Oakland, California; two days before the fifth anniversary of her sinking.

Loss
In May 1947, a two-tug towing operation began to move the hull of the Oklahoma from Pearl Harbor to the scrapyard in San Francisco Bay. However, disaster struck on 17 May when the ships entered a storm more than 500 mi from Hawaii. The tug Hercules put her searchlight on the former battleship, revealing that she had begun listing heavily. After radioing the naval base at Pearl Harbor, both tugs were instructed to turn around and head back to port. But suddenly, without warning, the Hercules was pulled back past the Monarch, which was being dragged backwards at 15 knots herself. The Oklahoma had began to sink straight down causing water to swamp the sterns of both tugs.

Fortuitously both tug skippers, Kelly Sprague of the Hercules and George Anderson of the Monarch, had loosened their cable drums which connected the 1400 ft tow lines to the Oklahoma. As the battleship rapidly sank, the line from the Monarch quickly played out releasing the tug. However the Hercules' cables didn't release until the last possible moment, leaving her tossing and pitching above the grave of the sunken Oklahoma.

Memorial
In 2003, the U.S. Navy recovered part of the mast of the Oklahoma from the bottom of Pearl Harbor. In 2007, it was flown to Tinker Air Force Base in Oklahoma, then delivered to War Memorial Park in Muskogee, Oklahoma for permanent display.

On December 7, 2007 the 66th Anniversary of the attack on Pearl Harbor a memorial for the 429 crew members who were killed in the attack was dedicated on Ford Island, just outside the entrance to where the USS Missouri (BB-63) is docked as a museum. The Missouri is moored where the Oklahoma was moored when she was sunk.
