Diving the USS Arkansas 070524

USS Arkansas (BB-33), one of two Wyoming-class battleships, commissioned in 1912. One of the oldest ships of World War II, she was expended and wrecked in an atomic bomb test at Bikini Atoll in July 1946, where her wreckage still lies.
Arkansas was 562 ft (171 m) long overall and had a beam of 93 ft 3 in (28 m) and a draft of 28 ft 6 in (9 m). She displaced 26,000 long tons (26,417 t) as designed and up to 27,243 long tons (27,680 t) at full load. The ship was powered by four-shaft Parsons steam turbines and twelve coal-fired Babcock & Wilcox water-tube boilers rated at 28,000 shp (21,000 kW), generating a top speed of 20.5 knots (38.0 km/h; 23.6 mph). The ship had a cruising range of 8,000 nmi (15,000 km; 9,200 mi) at a speed of 10 knots (19 km/h; 12 mph).
The ship was armed with a main battery of twelve 12-inch/50 caliber Mark 7 guns[a] guns in six twin Mark 9 gun turrets on the centerline, two of which were placed in a superfiring pair forward. The other four turrets were placed aft of the superstructure in two superfiring pairs. The secondary battery consisted of twenty-one 5-inch (127 mm)/51 caliber guns mounted in casemates along the side of the hull. The main armored belt was 11 in (279 mm) thick, while the gun turrets had 12 in (305 mm) thick faces. The conning tower had 11.5 in (292 mm) thick sides.
In 1925, Arkansas was modernized in the Philadelphia Navy Yard.[2] Her displacement increased significantly, to 26,066 long tons (26,484 t) standard and 30,610 long tons (31,101 t) full load. Her beam was widened to 106 ft (32 m), primarily from the installation of anti-torpedo bulges, and draft increased to 29 ft 11.75 in (9 m). Her twelve coal-fired boilers were replaced with four White-Forster oil-fired boilers that had been intended for the ships cancelled under the terms of the Washington Naval Treaty; performance remained the same as the older boilers. The ship's deck armor was strengthened by the addition of 3.5 in (89 mm) of armor to the second deck between the end barbettes, plus 1.75 in (44 mm) of armor on the third deck on the bow and stern. The deck armor over the engines and boilers was increased by 0.75 in (19 mm) and 1.25 in (32 mm), respectively. Five of the 5-inch guns were removed and eight 3 in (76 mm)/50 caliber anti-aircraft guns were installed. The mainmast was removed to provide space for an aircraft catapult mounted on the Number 3 turret amidships.
