Each turret would have required a crew of 94 men to operate.
They fired projectiles weighing up to 2,700 lb (1,200 kg) at a maximum speed of 2,690 ft/s (820 m/s) with a range of up to 24 nmi (28 mi; 44 km). The lower spaces would have contained rooms for handling the projectiles and storing the powder bags used to fire them. 8 could penetrate 20 inches (508 mm) of steel armor plate. The 20 mm guns, however, were found to be ineffective against the Japanese kamikaze attacks used during the latter half of World War II.
At 20,000 yd (18.3 km), the Mk. Contrary to popular belief, the ships would not have moved sideways noticeably when a broadside was fired.The guns would have been elevated from −5° to +45°, moving at up to 12° per second. At maximum range the projectile would have spent almost 1½ minutes in flight. . They would have landed on the water and taxied to the stern of the ship to be lifted by a crane back to the catapult.The Vought OS2U Kingfisher was a lightly armed two-man aircraft designed in 1937. The turrets would not have been attached to the ship, but would have rested on rollers, which meant that had any of the Montana-class ships capsized, the turrets would have fallen out.Each turret would have cost US$1.4 million, but this figure did not take into account the cost of the guns themselves.The turrets would have been "three-gun", not "triple", because each barrel would have elevated and fired independently. Very intresting :medal: Sad that it was not buildt :sad:The primary armament of a Montana-class battleship would have been 12 16"/50 caliber Mark 7 gun, which were to be housed in four three-gun turrets: two forward and two aft. At the time the Montana class was set to begin construction, the rangekeepers had gained the ability to use radar data to help target enemy ships and land-based targets. The type of aircraft used would have depended on when exactly the battleships would have been commissioned, but in all probability they would have used either the Kingfisher or the Seahawk.
These guns, designed specifically for the Montanas, were to be the replacement for the 5-inch (127 mm)/38 cal secondary gun batteries then in widespread use with the US Navy.The 5-inch (127 mm)/54 cal gun turrets were similar to the 5-inch (127 mm)/38 cal gun mounts in that they were equally adept in an anti-aircraft role and for damaging smaller ships, but differed in that they weighed more, fired heavier rounds of ammunition, and resulted in faster crew fatigue than the 5-inch (127 mm)/38 cal guns. The Oerlikon 20 mm AA gun remained the primary anti-aircraft weapon of the United States Navy until the introduction of the 40 mm Bofors AA gun in 1943.These guns are air-cooled and use a gas blow-back recoil system. Naval Historical Center. You need to play a total of 1 battles to post in this section. USS Montana (BB-67), would have been the lead ship of the Montana-class battleship s however, the entire class was cancelled in 1943; USS Montana (SSN-794), will be a Virginia-class submarine; This article includes a list of ships with the same or similar names. The main reason for this was logistical: the largest US shipyards were located on the East Coast of the United States, while the United States had territorial interests in both oceans. 13 HC (High-Capacity—referring to the large bursting charge) shell was available. BBN-65 USS Montana by SILVER-70CHEV on DeviantArt. As a result, hull numbers BB-65 and BB-66 were assigned to the Iowa-class ships USS Illinois and USS Kentucky while the Montanas were renumbered BB-67 to BB-71. She was to be named in honour of the 18th state and was assigned to the Norfolk Navy Yard that was preparing to lay her down at their shipyard at Portsmouth, Virginia. For unarmored targets and shore bombardment, the 1,900 lb (860 kg) Mk. The addition of the No. 4 turret would have allowed Montana to overtake the Yamato as the battleship having heaviest broadside overall; Montana and her sisters would have had a broadside of 32,400 lb (14,700 kg) vs. 28,800 lb (13,100 kg) for Yamato.
