USS Arizona BB-39

Here are some more images of Trumpeter's 1/200 scale USS Arizona (BB-39) Battleship.
Probably the most detailed and largest Arizona kit you will find. A beautiful model kit.

From Wikipedia"
USS Arizona (BB-39) was a Pennsylvania-class battleship built for the United States Navy and the first to be named "Arizona". On 4 March 1913, Congress authorized the construction of Arizona, named to honor the 48th state's admission into the union on 14 February 1912. The ship was the second and last of the Pennsylvania class of "super-dreadnought" battleships. Her keel was laid at the Brooklyn Navy Yard on 16 March 1914. She was launched on 19 June 1915, sponsored by Esther Ross, the daughter of a prominent Arizona pioneer, W.W. Ross of Prescott, Arizona. The ship's remaining machinery, including new Parsons turbines, was installed, and she was commissioned at her builder's yard on 17 October 1916, with Captain John D. McDonald in command.
Arizona served stateside during World War I. She is mostly remembered because of her sinking, with the loss of 1,177 lives, during the Japanese attack on Pearl Harbor on 7 December 1941, the event that provoked the United States into entering World War II. Unlike most of the other ships sunk or damaged that day, the Arizona could not be salvaged, although the U.S. Navy removed several elements of the ship that were reused.
The wreck still lies at the bottom of Pearl Harbor. The USS Arizona Memorial, dedicated in 1962 to all those who died during the Pearl Harbor attack, was built astraddle the ship's hull. The Arizona retains the right, in perpetuity, to fly the United States flag as if she were an active, commissioned naval vessel.
Arizona was significantly larger than her predecessors of the Nevada class. As completed she had an overall length of 608 feet (185.3 m), a beam of 97 feet (29.6 m) (at the waterline), and a draft of 29 feet 3 inches (8.9 m) at deep load. This was 25 feet (7.6 m) longer than the older ships. She displaced 29,158 long tons (29,626 t) at standard and 31,917 long tons (32,429 t) at deep load, over 4,000 long tons (4,060 t) more than the older ships. The ship had a metacentric height of 7.82 feet (2.4 m) at deep load.
The ship had four Parsons steam turbine sets, each of which drove a propeller 12 feet 1.5 inches (3.7 m) in diameter. They were powered by twelve Babcock & Wilcox water-tube boilers. The turbines were designed to produce a total of 31,500 shaft horsepower (23,500 kW), but only achieved 29,366 shp (21,898 kW) during Arizona's sea trials, when she slightly exceeded her designed speed of 21 knots (39 km/h; 24 mph). She was designed to carry 1,548 long tons (1,573 t) of fuel oil, but had a maximum capacity of 2,305 long tons (2,342 t). At full capacity, the ship could steam at a speed of 12 knots (22 km/h; 14 mph) for an estimated 7,552 nautical miles (13,990 km; 8,690 mi) with a clean bottom. She had four 300-kilowatt (402 hp) turbo generators.
Arizona carried twelve 45-caliber 14-inch guns in triple gun turrets. The turrets were numbered from I to IV from front to rear. The guns could not elevate independently and were limited to a maximum elevation of +15° which gave them a maximum range of 21,000 yards (19,000 m). The ship carried 100 shells for each gun. Defense against torpedo boats was provided by twenty-two 51-caliber five-inch guns mounted in individual casemates in the sides of the ship's hull. They proved to be very wet and could not be worked in heavy seas. At an elevation of 15°, they had a maximum range of 14,050 yards (12,850 m). Each gun was provided with 230 rounds of ammunition. The ship mounted four 50-caliber three-inch guns for anti-aircraft defense, although only two were fitted when completed. The other pair were added shortly afterwards on top of Turret III. Arizona also mounted two 21-inch (533 mm) torpedo tubes and carried 24 torpedoes for them.
The Pennsylvania-class design continued the all or nothing principle of armoring only the only most important areas of the ship begun in the preceding Nevada class. The waterline armor belt of Krupp armour measured 13.5 inches (343 mm) thick and only covered the ship's machinery spaces and magazines. It had a total height of 17 feet 6 inches (5.3 m), of which 8 feet 9.75 inches (2.7 m) was below the waterline; beginning 2 feet 4 inches (0.7 m) below the waterline, the belt tapered to its minimum thickness of 8 inches (203 mm). The transverse bulkheads at each end of the ship ranged from 13 to 8 inches in thickness. The faces of the gun turrets were 18 inches (457 mm) thick while the sides were 9–10 inches (230–250 mm) thick and the turret roofs were protected by 5 inches (127 mm) of armor. The armor of the barbettes was 18 to 4.5 inches (457 to 114 mm) thick. The conning tower was protected by 16 inches (406 mm) of armor and had a roof eight inches thick.
The main armor deck was three plates thick with a total thickness of 3 inches (76 mm); over the steering gear the armor increased to 6.25 inches (159 mm) in two plates. Beneath it was the splinter deck that ranged from 1.5 to 2 inches (38 to 51 mm) in thickness. The boiler uptakes were protected by a conical mantlet that ranged from 9–15 inches (230–380 mm) in thickness. A three-inch torpedo bulkhead was placed 9 feet 6 inches (2.9 m) inboard of the ship's side and the ship was provided with a complete double bottom. Testing in mid-1914 revealed that this system could withstand 300 pounds (140 kg) of TNT.
Shortly before 8:00 am, Japanese aircraft from six aircraft carriers struck the Pacific Fleet as it lay in port at Pearl Harbor, and—in the ensuing two attack waves—wrought devastation on the Battle Line and on air and military facilities defending Pearl Harbor. Onboard Arizona, the ship's air raid alarm went off about 07:55, and the ship went to general quarters soon thereafter. Shortly after 08:00, the ship was attacked by 10 Nakajima B5N "Kate" torpedo bombers, five each from the carriers Kaga and Hiryū. All of the B5Ns were carrying 410-millimeter (16.1 in) armor-piercing shells modified into 797-kilogram (1,760 lb) aircraft bombs. Flying at an estimated altitude of 3,000 meters (9,800 ft) Kaga's aircraft bombed from amidships to the ship's stern and were followed shortly afterwards by Hiryu's bombers which bombed the bow area.
The preliminary report, filed on 28 January 1942, on the damage suffered by Arizona during the attack listed seven bomb hits as well one torpedo hit on the port bow forward. This last hit was based on a report from the captain of the repair ship Vestal moored alongside and could not be verified at the time. One bomb was thought to have gone down the stack, but this was contradicted when the ship's superstructure was salvaged in 1942 and the cap of the funnel was intact. Later assessments show a total of four hits on the Arizona, plus three near misses. The near miss off the port bow is believed to have caused observers to believe that the ship had been torpedoed, although no torpedo damage has been found. The sternmost bomb ricocheted off the face of Turret IV and penetrated the deck to detonate in the captain's pantry, causing a small fire. The next forwardmost hit was near the port edge of the ship, abreast the mainmast, and probably detonated in the area of the anti-torpedo bulkhead. The next bomb struck near the port rear 5-inch AA gun.
The last bomb hit at 08:06 in the vicinity of Turret II, likely penetrating the armored deck near the ammunition magazines located in the forward section of the ship. While not enough of the ship is intact to judge the exact location, its effects are indisputable. About seven seconds after the hit, the forward magazines detonated in a cataclysmic explosion. It mostly vented through the sides of the ship and destroyed much of the interior structure of the forward part of the ship. This caused the forward turrets and conning tower to collapse downwards some 25–30 feet (7.6–9.1 m) and the foremast and funnel to collapse forward. The explosion took 1,177 lives of the 1,400 crewmen on board at the time, almost half of the lives lost during the attack. The explosion touched off fierce fires that burned for two days; debris showered down on Ford Island in the vicinity. Ironically, the blast from this explosion also put out fires on the repair ship Vestal, which was moored alongside.
Two competing theories have arisen about the cause of the explosion. The first is that that the bomb detonated in or near the black powder magazine used for the ship's saluting guns. This would have detonated first and then ignited the smokeless powder magazine which was used for the ship's main armament. A 1944 Navy Bureau of Ships report suggests that a hatch leading to the black powder magazine was left open, possibly with inflammable materials stocked nearby. The Naval History & Heritage Command explained that black powder might have been stockpiled outside of the armored magazine. This theory is attractive because black powder is easy to ignite and the relatively small amount of explosive filler in the bomb could have easily done so. The alternative explanation is that the bomb penetrated the armored decks and detonated directly inside one of the starboard magazines for the main armament. The problem is that smokeless powder is relatively insensitive to fire and the 14-inch powder bags actually required a black powder pad to ignite the powder. However, it seems unlikely that a definitive answer to this question will ever be found as the surviving physical evidence is insufficient to determine the cause of the magazine explosion.

Japanese credit for sinking

Credit for the hit was officially given to Petty Officer Noburu Kanai, who was considered to be the JNAF's "crack" bombardier; his pilot was Tadashi Kusumi.

Awards and recognition

Acts of heroism on the part of Arizona's officers and men were many, headed by those of Lieutenant Commander Samuel G. Fuqua, the ship's damage control officer, whose coolness in attempting to quell the fires and get survivors off the ship earned him the Medal of Honor.
Posthumous awards of the Medal of Honor also went to Rear Admiral Isaac C. Kidd, the first flag officer killed in the Pacific war, and to Captain Franklin Van Valkenburgh, who reached the bridge and was attempting to defend his ship when the bomb that hit the ammunition magazines destroyed her.
