They were also exactly the type of ships for which the college had argued unsuccessfully to add to the U.S. Navy before switching to battlecruisers. Later planning called for the use of these guns in the Iowa-class battleships, but miscommunication between design bureaus led to the 16"/50 caliber Mark 7 gun being used instead. 8 diamonds; 966 views, 6 today; 42 downloads, 0 today; 2 comments; 2 favorites; 8. Basically an extended version of the 16"/45 caliber Mark 1 gun used on the Colorado class, it fired the same 2,100-pound (950Â kg) shell as the Mark 1 at a muzzle velocity of 2,800 fps (853 mps) and rate of two rounds per minute to a range of 44,500 yards (40,700Â m) at an elevation of 45 degrees. Lexington had 24 of these guns aboard when she was sunk in early 1942. A disadvantage was the formation of a heavy layer of water which would creep up along the outer plating of the forecastle at higher speeds. , Lexington's eight-inch gun turrets were removed in early 1942, but they were replaced by seven additional quadruple 1.1-inch gun mounts as a temporary measure. , By 1908, the summer conference had come to favor battlecruisers over armored cruisers. , Conversion of a Lexington to an aircraft carrier had both positive and negative aspects when compared with a "specifically designed carrier". The height of the hangar was not exceeded on an American aircraft carrier until the Forrestal-class ships appeared in the mid-1950s. Miscellaneous aircraft included two Grumman JF Duck amphibians, plus one in reserve, and three active and one spare Vought O2U Corsair observation aircraft. This article is about the original battlecruiser class. The Navy countered that doing so would mean a complete rearrangement of machinery spaces and a reduction in underwater protection. , The Royal Navy temporarily assigned a young constructor, Stanley Goodall, to C&R to assist in this task. The Lexington-class ships were originally designed to be battlecruisers, with heavy guns, high speed, and moderate armor protection. 1, art. Her mission was cancelled and she returned to Pearl Harbor a week later. This challenge was complicated in a capital ship by the heavy weight of main turrets and guns. To her left Tosa-class battleship, Amagi-class battlecruiser, & Kii-class battleship by Epitaph. , Construction finally began upon the battlecruisers in 1920 and 1921, after a delay of almost five months. The design challenges the Navy's Bureau of Construction and Repair (C&R) faced with this class were considerable, as the combined requirements of optimum hitting power, extreme speed and adequate protection taxed the knowledge of its naval architects and the technology of the time. The belt covered the middle 530 feet (161.5Â m) of the ships. [A 1] While these six vessels were requested in 1911 as a reaction to the building by Japan of the Kongō class, the potential use for them in the U.S. Navy came from a series of studies by the Naval War College which stretched over several years and predated the existence of the first battlecruiser, HMS Invincible. As a result, all but three of the Navy's remaining Mark 2 and 3 guns were sent to the Army to also be used as coastal defense guns. Several days into the battle, she was badly damaged by kamikaze hits and was forced to return to the United States for repairs. Its maximum range was 11,000 yards (10,000 m) although the effective range was around 4,000–5,000 yards (3,700–4,600 m). Her construction was suspended in February 1922, under the terms of the Washington Treaty, and after she was formally cancelled in August 1923, her hull was scrapped on the building ways. http://www.history.navy.mil/photos/usnshtp/bb/cc1.htm, "United States of America 14"/50 (35.6 cm) Mark 4 and Mark 6", http://www.navweaps.com/Weapons/WNUS_14-50_mk4.htm, "United States of America 16"/50 (40.6 cm) Mark 2 and Mark 3", http://www.navweaps.com/Weapons/WNUS_16-50_mk2.htm, "United States of America 5"/51 (12.7 cm) Marks 7, 8, 9, 14 and 15", http://www.navweaps.com/Weapons/WNUS_5-51_mk7.htm, "United States of America 6"/53 (15.2 cm) Marks 12, 14, 15 and 18", http://www.navweaps.com/Weapons/WNUS_6-53_mk12.htm, "United States of America 3"/23.5 (7.62 cm) Marks 4 and 14, 3"/23 (7.62 cm) Marks 7, 9, 11 and 13", http://www.navweaps.com/Weapons/WNUS_3-23_mk13.htm, Washington Naval Treaty, Chapter II, Part III, Section II, "Board for Selling Doomed Warships; Admirals Oppose Sinking at Sea Under Terms of the Five Power Naval Treaty", http://query.nytimes.com/gst/abstract.html?res=9B01EFD71739EF3ABC4B53DFB3668389639EDE, Washington Naval Treaty, Chapter I, Article IX, http://www.history.navy.mil/danfs/l6/lexington-iv.htm, http://www.history.navy.mil/danfs/s6/saratoga-v.htm, http://www.history.navy.mil/danfs/r2/ranger-vii.htm, "USS Constitution (CC-5), 1918 Program – construction cancelled in 1923", http://www.history.navy.mil/photos/sh-usn/usnsh-c/cc5.htm, http://www.history.navy.mil/danfs/u1/united_states.htm, http://books.google.de/books/about/Theodore_Roosevelt.html?id=TNmrjwEACAAJ&redir_esc=y, http://books.google.com/books?id=HByyEWPFvSoC&pg=PA200&dq=theodore+roosevelt+japan+navy&hl=en&sa=X&ei=bCSjT-ytBeXgiALOtpziDA&ved=0CF8Q6AEwCA#v=onepage&q=theodore%20roosevelt%20japan%20navy&f=false, http://webcache.googleusercontent.com/scholar?hl=en&lr=&q=cache:1k0cpiXe0xYJ:pages.prodigy.net/mpsinesi/U.S.%2520Navy%27s%2520Light%2520Cavalry.doc, List of aircraft carriers of the United States Navy, https://military.wikia.org/wiki/Lexington-class_battlecruiser?oldid=4414907, Pages using duplicate arguments in template calls, Fore River Shipbuilding, New York Shipbuilding and Newport News Shipbuilding and Drydock Company, 10,000 nmi (19,000 km; 12,000 mi) at 10 knots (19 km/h; 12 mph), Fore River Shipyard, Quincy, Massachusetts, Newport News Shipbuilding, Newport News, Virginia, New York Shipbuilding, Camden, New Jersey, (converted from battlecruisers in accordance with the. They would be protected with 8 inches (203Â mm) of belt and turret armour and 3 inches (76Â mm) of deck armour and be capable of a speed of 20.5 knots. Posterior. The forward elevator was 30-by-60-foot (9.1 m × 18.3 m) and had a capacity of 16,000 pounds (7,257.5 kg). You could also do it yourself at any point in time. On 29 August, it suggested that C&R research a ship under 30,000 tons that could steam at 29 knots (54 km/h), carry eight 14-inch (360 mm) and twenty-four 5-inch (130 mm) guns and have a protective system comparable to the Nevada-class battleships. , IJN battlecruiser Kongō, for which the Lexington class was to be a response, Therefore, while the Navy did not react as Germany and Britain built increasing numbers of battlecruisers, it took a very different tack when Japan laid down its first ship of this class, the Kongō, in Britain on 17 January 1911. Six 750-kilowatt (1,010 hp) DC turbo generators were installed in the upper levels of the two main turbine compartments. The General Board retained these sketches but did not recommend construction. Forward, the belt ended in a bulkhead that also tapered from seven to five inches in thickness. Intended as fast combat scouts for the battle fleet, these large ships had a prolonged development history. They displaced 43,500 long tons (44,200 t) at normal load and 44,638 long tons (45,354 t) at deep load. The conning tower armor was 12 inches (305 mm) thick, and it had a communications tube with 10 inches (254 mm) sides ran from the conning tower down to the lower conning position on the 1st platform deck. Other factors for this decision were the discovery of plans by Britain and Japan for new battlecruisers armed with 15- and 16-inch guns (respectively) and the recommendation of the Bureau of Ordnance to give these ships the ability "to inflict fatal damage on the enemy's most powerful vessels at a distance no less than that at which she can be reached by the heavy gunfire of these opponent battleships." The Lexington-class battlecruiser was a series of six warships planned for construction during the early 1920s, but were scrapped or altered under the terms of the Washington Naval Treaty. For information on the two members that were converted to aircraft carriers, see Lexington-class aircraft carrier.. I know there are people who want the Lexington class ships in their Battlecruiser form, I have a question if WG decides to implement her, what name will she go under since the name has already been used as a CV and also will it pose any issues when it comes to tier and etc? Another idea, subsequently adopted, was to design the forecastle to break abaft the turrets.  Despite these factors and the fact that American companies would have struggled to produce the very large geared steam turbines needed for such big ships, the Curtis Company tried unsuccessfully to convince the Navy to reverse this decision. , The waterline belt of the Lexington-class ships tapered 7â5 inches (178â127Â mm) in thickness from top to bottom and was angled 11Â° outwards at the top to increase the armor's relative thickness to horizontal, close-range fire (a concept taken from HMS Hood).  However, that July, U.S. Secretary of State Charles Evans Hughes called for a conference in Washington D.C. to be held that November. This opened the opportunity for a massive redesign, the need for which had become apparent in light of experience gained in the Battle of Jutland, fought shortly after the initial design for the Lexingtons had been approved and in which three British battlecruisers had been lost. At +85° elevation they had an anti-aircraft ceiling of 29,800 feet (9,100 m). , Four 3"/23 caliber Mark 11 anti-aircraft guns were planned for the original and first redesigned versions of the Lexingtons. The steering gear, however, was protected by two layers of STS that totaled 3 inches (76 mm) on the slope and 4.5 inches (114 mm) on the slope. The aft elevator measured 30-by-36-foot (9.1 by 11.0 m) and could only lift 6,000 pounds (2,721.6 kg). Naval Intelligence confirmed she was to be the first of four ships, the other three to be built in Japan, which would form a fast division for the IJN. Lexington -class battlecruiser - a class of six battlecruisers designed during World War I, they were being constructed when the Washington Naval Treaty forced the cancellation of the class. During this time of planning and construction, the original sail frigate USS Constitution, still in existence at Boston, was renamed Old Constitution so that her name might have been borne by the battlecruiser; the cancellation of CC-5 saw the restoration of Old Ironsides' original name. They fired 13-pound (5.9 kg) shells at a muzzle velocity of 2,700 ft/s (820 m/s).  Four General Electric turbo generators powered each propeller shaft and each was rated at 35,200 kilowatts (47,200Â hp), 5000 volts and 4620 amps of direct current (DC). An enlarged belt was required by a deeper hull, as all American battlecruiser studies required deep hulls to retain their girder strength because those hulls had to be abnormally long to attain their speed. The following day, the Secretary of the Navy asked the General Board to consider the construction of American battlecruisers for Pacific service, as the Pennsylvanias and Tennessees would no longer be viable units in the face of such opposition. Also, while the 8 inches (200Â mm) of belt armor being considered was not an impressive amount in itself, the belt's running potentially along 80 percent of the waterline and covering the entire side amidships made the amount of armor protection impressive by European standards. The General Board, not willing to forego battleship construction in favor of auxiliary types such as battlecruisers, balked. The stated goal was to curb the rapidly growing and extremely expensive naval construction programs. (d) of Washington Treaty for providing means against air and submarine attack". This opened the opportunity for a massive redesign, the need for which had become apparent in light of experience gained in the Battle of Jutland, fought shortly after the initial design for the Lexingtons had been approved and in which three British battlecruisers had been lost.
