New York-class battleship

The New York class of battleship was a class of ships designed and constructed by the United States Navy between 1908 and 1914. The two ships of the class, USS New York (BB-34) and USS Texas (BB-35), each saw extensive service beginning in the occupation of Veracruz, World War I, and World War II.

Designed as a more heavily armed improvement over the previous, the New York class was the first battleship to feature the 14"/45 caliber gun, but was one of the last battleship classes designed with several features, including a five-turret layout and coal for fuel. The class also suffered several deficiencies such as a lack of anti-aircraft weaponry and armor layout, which were addressed with the subsequent . Because of these deficiencies, both ships saw several extensive overhauls over the course of their careers which greatly changed their profiles.

Both New York and Texas entered service in 1914 and immediately served in the occupation of Veracruz, and service reinforcing the Grand Fleet in the North Sea during World War I, during which time New York is believed to have sunk a U-boat in an accidental collision. Both ships undertook numerous training exercises and overhauls during the interwar era, and joined the Neutrality Patrol at the beginning of World War II. Outmoded by more advanced battleships in service, both ships served primarily as convoy escorts and naval artillery during the war. New York supported Operation Torch in North Africa, undertook convoy patrols and training in the Atlantic, and supported the Battle of Iwo Jima and the Battle of Okinawa. Texas supported Operation Torch, Operation Overlord, the bombardment of Cherbourg, Operation Dragoon and the battles at Iwo Jima and Okinawa. Following the war, New York was used as a target ship in Operation Crossroads and sunk as a target in 1948, while Texas was converted into a museum ship, and remains permanently moored in San Jacinto State Park today.

Background
The New York class was the fifth of 11 separate classes built by the United States Navy between 1906 and 1919, a total of 29 battleships and 6 battle-cruisers. Virtually the entire American battle line was being designed from pre-dreadnought experience and observation of foreign designs. The design of the New York-class battleship originated in the 1908 Newport Conference, which resulted in a new method for battleship design, with the General Board taking a more active role in the design process of ships, and the navy's Board on Construction would implement the design instead of creating it. While the New York class was mostly designed by the Board on Construction, lessons learned on the class allowed the General Board to take the lead on the proceeding s.

The Newport Conference established a general consensus among leaders that U.S. Navy ships should carry larger batteries in response to the increasing caliber of battleships in other countries, notably the BL 13.5 inch Mk V naval gun which had been introduced by the Royal Navy's, as well as the German Navy's shift from 28 cm to 30.5 cm guns. There was debate at the time as to whether the s, laid down in 1909, should carry heavier armament than the 12"/45 caliber Mark 5 gun. Ultimately, on 30 March 1909, U.S. Congress approved the construction of two "Design 601" battleships, also known as Battleship 1910 with six 12-inch (305 mm) turrets, which the General Board had selected over two 14-inch (356 mm) designs in 1909. These would become the . At the same time, the General Board began planning for the next class of ships, and on 21 April 1909 decided on two battleships with similar sizes, and after some debate about main guns approval of two battleships was granted on 24 June in 2010. In 1911 the U.S. Senate's Naval Affairs Committee suggested reducing the size of the ships as part of a $24,000,000 budget reduction, but Secretary of the Navy George von Lengerke Meyer fought to keep the original design and the ships were not altered.

The class is generally referred to as the New York class, but it is also occasionally called the Texas class because USS New York (BB-34) was completed several months after her sister, USS Texas (BB-35).

General characteristics
As designed, the ships had a standard displacement of 27,000 t and a full-load displacement of 28,367 t. They were 573 ft in length overall, 565 ft at the waterline, and had a beam of 95 ft and a draft of 28 ft. The ships underwent significant changes and increases in armor and armament over their operational lives. Following her fourth and final refit in 1943, New York increased her displacement to 29,340 t standard and 34,000 t full-load. The final refit for Texas came in 1945, after which she displaced 29,500 t standard and 32,000 t at full load. As designed, the ships had a crew complement consisted of 1,042 officers and enlisted men. By 1945, Texas was carrying 1,723 officers and enlisted men with the addition of crews for additional weapons as well as a new complement of U.S. Marines.

Armament
The main battery of the class consisted of ten 14"/45 caliber guns (356 mm), arrayed in five twin turrets designated A, B, Q, X, and Y. As constructed, these turrets had an elevation of 15 degrees, but this was increased to 30 degrees during an overhaul in 1940–1941. The class was the last to feature a Q turret mounted amidships. In 1910 the U.S. Navy's Bureau of Ordnance had successfully designed and tested its 14 in naval gun. The gun proved to have remarkable accuracy and uniformity of pattern. The New York class was the fifth class of U.S. dreadnought battleship design created, and work had already started on the sixth design, the . By 1910 no U.S. dreadnought class battleship had yet hit the water, as all were either at some stage of building or in design. Virtually the entire U.S. Navy battle line was being designed by drawing on experience from pre-dreadnought designs or from observation of foreign battleship designs.

As built, both ships also carried 21 5"/51 caliber guns (127 mm) arrayed ten to a side with one in the stern, primarily for defense against destroyers and torpedo boats. Many of the 5-inch guns were poor in accuracy in rough seas due to being mounted near the ends of the ship and below the main deck. The ships were not designed with anti-aircraft (AA) defense in mind, and with the development of naval aviation, this was seen as a serious drawback to the class. The New York class was the first U.S. battleship to mount anti-aircraft guns, with two 3"/50 caliber guns mounted on platforms on top of the boat cranes of Texas in 1916. In 1918, the secondary armament was reduced to sixteen 5"/51 caliber guns, eight to a side, as the guns near the ends of the ship were difficult to work in any kind of sea. When both ships were refitted 1925-26, AA defense was increased with eight 3"/50 caliber guns arrayed four to a side. Six of the 16 remaining 5-inch guns were relocated higher in the ship to new casemates on the main deck. The New York class also initially featured four torpedo tubes for the Bliss-Leavitt Mark 3 torpedo, instead of the previous two, because of advances in torpedo performance increasing the prominence of the weapon. However, the torpedo tubes were removed in the 1925-26 refit.

Magazine and machinery spaces were enclosed in the protected hull. Magazine volume was reduced for increased machinery, with each magazine accommodating 75 to 80 shells and charges, while more shells were carried in their turrets and handling rooms.

In 1937 eight 1.1 inch (28 mm) AA guns in two quadruple mounts were added to improve the light AA armament. The ships were more extensively refitted with large amounts of light AA guns at the expense of the 5 inch 51 caliber guns in 1942, as the attack on Pearl Harbor had shown pre-war light AA armament to be inadequate. The 1.1 inch quad mounts were removed and 24 Bofors 40 mm guns were added in quadruple mounts (later increased to 40 guns), while 42 Oerlikon 20 mm guns in single mounts were also added. The 3 inch AA gun armament was increased to 10 guns, while the 5 inch gun armament was reduced to 6 guns.

Armor
The ships continued the armor suite of the Wyoming class with minor improvements. The deck armor scheme would continue to remain distinctly inferior to the succeeding Nevada class with their all or nothing armor scheme. However the leap forward in range provided by improved fire control was not yet envisioned and had it been there would not have been time to include it within the current design. The ship provided a 12 in belt tapering to 10 in and 6.5 in casement armor with internal partitioning. The New York class was the first to incorporate an armored central plotting room below decks, but atop the protective deck, and enclosed in a thin box of splinter armor.

Armor on New York class consisted of belt armor from 10 to 12 ft thick. Their lower casemates had between 9 in and 11 in of armor, and their upper casemate had 6 in of armor. Deck armor was 2 in thick, and turret armor was 14 in on the face, 4 in on the top, 2 in on the sides, and 8 in on the rear. Armor on her barbettes was between 10 in and 12 in. Conning towers were protected by 12 in of armor, with 4 in of armor on the tops. In all, the armor totaled 261.67 t on the upper casemate, 1,680.33 t on the lower casemate, 1,549.16 t along the belt, 127.42 t on the bulkheads, 1,322.11 t on the splinter deck, 2,085.39 t on the barbettes, and 856.11 t on the conning tower for a total protection of 8,120.62 t.

Propulsion
The ships were powered by 14 Babcock and Wilcox coal-fired boilers driving two dual-acting triple expansion reciprocating steam engines, with 28,100 indicated horsepower producing a maximum speed of 21 knots. They had a range of 7,060 nmi at 10 knots. Initially, designs called for a 14 percent increase in power to 32,000 shp over the 28,000 shp of the preceding class. However, it was discovered that greater propulsive efficiency of the reciprocating engine allowed a reduction in installed power, needing only 28,100 shp to make 21 knots.

The New York class was the final class of U.S. battleship to be powered by coal. The class was designed to carry 2,850 t of coal, the most of any battleship class. In 1910, the succeeding battleships of the Nevada class were designed with fuel oil in mind. Both ships were converted to carry fuel oil in 1926, and had a capacity of 5,200 t of oil. Six new Bureau Express oil-fired boilers replaced the 14 older design coal-fired boilers at that time with no loss of power.

Construction
Funding for the battleships was authorized by a 24 June 1910 act, which called for the ships to cost no more than $6,000,000. The act also specified new labor policies for their construction which put strict limits on labor hours and working conditions for shipyard employees. Bids were solicited only for Battleship No. 35 on 27 September 1910, while Battleship No. 34 was to be built by New York Navy Yard. Bids opened for No. 35 on 1 December. Ultimately Newport News Shipbuilding Company won the contract with a bid of $5,830,000. Battleship No. 35, named Texas, began construction first, on 17 April 1911, launched 18 May 1912, and completed on 12 March 1914. Battleship No. 34, later named New York, was laid down on 11 September 1911, launched on 30 October 1912, and completed on 15 April 1914.

By 1926, the New York class was considered obsolete compared with other battleships in service, so both ships received a complete refit. While several other battleships in service, including USS Utah (BB-31) and USS Florida (BB-30) were converted to training ships or scrapped, New York and Texas were chosen to be overhauled to increase their speed, armor, armament, and propulsion systems, in accordance with the Washington Naval Treaty of 1922. An additional 3,000 t were added for defense against aerial targets and submarines. Her 14 coal-fired boilers were replaced by six Bureau Express oil-fired boilers and the twin funnels were trunked into one, aft of the forward superstructure. Tripods were fitted in place of the lattice masts, and atop the forward tripod a control tower was installed. A tower was built amidships that contained additional fire control to backup the system on the foremast. A new aircraft catapult was installed atop "Q" turret, and cranes were installed on either side of the funnel for boat and aircraft handling. Additional deck protection was added, and each ship's beam was widened. The ships were fitted with anti-torpedo bulges, though these made maneuvering harder at low speeds and both rolled badly, and gunfire accuracy was reduced in rough seas.

USS New York


Shortly after commissioning, New York became flagship for the United States occupation of Veracruz in 1914. During World War I, she became flagship of Battleship Division 9, commanded by Rear Admiral Hugh Rodman. Sent to reinforce the British Grand Fleet in the North Sea, she conducted blockade and escort duties. She twice came into contact with German U-boats, and is believed to have accidentally sunk one. She returned to the United States at the end of the war, and began taking on patrol and training duties. New York was fitted with XAF RADAR in February 1938, including the first United States duplexer so a single antenna could both send and receive.

She was a part of the Neutrality Patrol following the outbreak of World War II, and In September 1939, and spent the beginning of the war escorting convoys between New York and Iceland. She saw action supporting Operation Torch, the Allied invasion of North Africa, where she targeted shore batteries threatening the landings in November 1942. She remained in convoy patrol and training for several years, until she was moved to the Pacific Fleet late in the war and supported landings on Iwo Jima in February 1945, and later the Invasion of Okinawa in April 1945. She was lightly damaged by a kamikaze attack in this battle. Following the war, she was used as a target ship during Operation Crossroads and subsequently studied for its effects, before being sunk as a target in 1948.

USS Texas


Texas also participated in the occupation of Veracruz for several months in 1914, before conducting training and ugrades to become the first ship of the U.S. Navy to mount anti-aircraft weapons. She conducted convoy patrols early in World War I and was the first U.S. ship to fire on a German one during a convoy mission in 1917. She joined other U.S. battleships in reinforing the British fleet near the end of the war and was present for the German surrender. In the inter-war period she became one of the first battleships to launch and operate aircraft, and frequently alternated her time between the Atlantic and Pacific waters on training exercises.

She was part of the Neutrality Patrol at the beginning of World War II and supported Allied landings at North Africa, and then conducted convoy patrol duty to North African and European ports throughout 1943. On 6 June 1944, she supported Operation Overlord, covering Allied landings on the beaches of Normandy, France, in particular the battle at Pointe du Hoc. Later that month on 25 June, she supported the Bombardment of Cherbourg and there was damaged when she was hit with a German artillery shell. In July she moved to support Operation Dragoon, the Allied invasion of southern France. Following extensive repairs and training, she moved to the Pacific and supported the invasion of Iwo Jima in February 1945. She then moved to support landings on Okinawa in April. Following the end of the war, Texas was decommissioned and in 1948 she was moved to San Jacinto State Park and converted into a museum ship, where she remains today.
