Armor: Aside from its firepower, a battleship's defining feature is its armor. The exact design and placement of the armor, inextricably linked with the ship's stability and performance, is a complex science honed over decades. A battleship is usually armored to withstand an attack from guns the size of its own, but the armor scheme of the preceding North Carolina class was only proof against 14-inch (356 mm) shells (which they had originally been intended to carry), while the South Dakota-class battleship (1939) and Iowa-class battleship classes were designed only to resist their original complement of Mark V 2,240 lb (1,020 kg) shells, not the new "super-heavy" 2,700 lb (1,200 kg) APC (Armor Piercing, Capped) Mark7 VIII shells they actually used. The Montanas were the only US battleships designed to resist the Mark VIII. Until the authorization of the Montana class all US battleships were built within the size limits for the Panama Canal. 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. Requiring the battleships to fit within the Panama Canal took days off the transition time from the Atlantic Ocean to the Pacific Ocean by allowing ships to move through the canal instead of sailing around South America. By the time of the Two Ocean Navy bill, the Navy realized that ship designs could no longer be limited by the Panama Canal and thus approved the Montana class knowing that the ships would be unable to clear the locks. This shift in policy meant that the Montana class would have been the only World War II–era US battleships to be adequately armored against guns of the same power as their own. Aircraft: The Montana-class would have used aircraft for reconnaissance and for gunnery spotting. 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. The aircraft would have been floatplanes launched from catapults on the ship's fantail. 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. Kingfisher: The Vought OS2U Kingfisher was a lightly armed two-man aircraft designed in 1937. The Kingfisher's high operating ceiling made it well-suited for its primary mission: to observe the fall of shot from a battleship's guns and radio corrections back to the ship. The floatplanes used in World War II also performed search and rescue for naval aviators who were shot down or forced to ditch in the ocean. Seahawk: In June 1942, the US Navy Bureau of Aeronautics requested industry proposals for a new seaplane to replace the Kingfisher and Curtiss SO3C Seamew. The new aircraft was required to be able to use landing gear as well as floats. Curtiss submitted a design on 1 August, and received a contract for two prototypes and five service-test aircraft on 25 August.The first flight of a prototype XSC-1 took place on 16 February 1944 at the Columbus, Ohio Curtiss plant. The first production aircraft were delivered in October 1944, and by the beginning of 1945 the single-seat Curtiss SC Seahawk floatplane began replacing the Kingfisher. Had the Montana-class been completed, they would have arrived around the time of this replacement, and would likely have been equipped with the Seahawk for use in combat operations and seaborne search and rescue.

Armament: The armament of the Montana-class battleships would have been similar to the preceding Iowa-class battleships, but with an increase in the number of primary and secondary guns for use against enemy surface ships and aircraft. Had they been completed, the Montanas would have been gun-for-gun the most powerful battleships the United States had constructed, and the only US battleship class that would have come close to equaling the Imperial Japanese Navy battleships Yamato and Musashi on a gun-for-gun and ton-for-ton basis. Main battery: 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. The guns, the same used to arm the Iowa-class battleships, were 66 ft (20 m) long – 50 times their 16-inch (406 mm) bore, or 50 calibers, from breechface to muzzle. Each gun weighed about 239,000 lb (108,000 kg) without the breech, or 267,900 lb (121,500 kg) with the breech. 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). At maximum range the projectile would have spent almost 1½ minutes in flight. 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. Each gun would have rested within an armored barbette, but only the top of the barbette would have protruded above the main deck. The barbettes would have extended either four decks (turrets 1 and 4) or five decks (turrets 2 and 3) down. The lower spaces would have contained rooms for handling the projectiles and storing the powder bags used to fire them. Each turret would have required a crew of 94 men to operate. 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. The ships could fire any combination of their guns, including a broadside of all 12. 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. The turrets would have rotated about 300° at about 4° per second and could even be fired back beyond the beam, which is sometimes called "over the shoulder". Within each turret, a red stripe on the wall of the turret, just inches from the railing, would have marked the boundary of the gun's recoil, providing the crew of each gun turret with a visual reference for the minimum safe distance range. Like most battleships in World War II, the Montana class would have been equipped with a fire control computer, in this case the Ford Mk 1A Ballistic Computer, a 3,150 lb (1,430 kg) rangekeeper designed to direct gunfire on land, sea, and in the air.This analog computer would have been used to direct the fire from the battleship's big guns, taking into account several factors such as the speed of the targeted ship, the time it takes for a projectile to travel, and air resistance to the shells fired at a target. 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 results of this advance were telling: the rangekeeper was able to track and fire at targets at a greater range and with increased accuracy, as was demonstrated in November 1942 when the battleship Washington engaged the Imperial Japanese Navy battleship Kirishima at a range of 18,500 yd (16.9 km) at night; the Washington scored at least nine heavy caliber hits that critically damaged the Kirishima and led to her scuttling. This gave the US Navy a major advantage in World War II, as the Japanese did not develop radar or automated fire control to the level of the US Navy. The large caliber guns were designed to fire two different 16-inch (406 mm) shells: an armor piercing round for anti-ship and anti-structure work, and a high explosive round designed for use against unarmored targets and shore bombardment. The Mk. 8 APC (Armor-Piercing, Capped) shell weighed in at 2,700 lb (1,200 kg), and was designed to penetrate the hardened steel armor carried by foreign battleships. At 20,000 yd (18.3 km), the Mk. 8 could penetrate 20 inches (508 mm) of steel armor plate. At the same range, the Mk. 8 could penetrate 21 ft (6.4 m) of reinforced concrete. For unarmored targets and shore bombardment, the 1,900 lb (860 kg) Mk. 13 HC (High-Capacity—referring to the large bursting charge) shell was available. The Mk. 13 shell could create a crater 50 ft (15 m) wide and 20 ft (6.1 m) deep upon impact and detonation, and could defoliate trees 400 yd (370 m) from the point of impact. The final type of ammunition developed for the 16-inch guns were W23 "Katie" shells. These shells were born from the nuclear deterrence that had begun to shape the US armed forces at the start of the Cold War. To compete with the Air Force and the Army, which had developed nuclear bombs and nuclear shells for use on the battlefield, the Navy began a top-secret program to develop Mk. 23 nuclear naval shells with an estimated yield of 15 to 20 kilotons. The shells entered development around 1953, and were reportedly ready by 1956; however, the cancellation of the Montana class meant that only the Iowa-class battleships, armed as they were with the same type of gun, could use the shells if the need had arisen. Secondary battery: The secondary armament for Montana and her sisters was to be 20 5-inch (127 mm)/54 cal guns housed in 10 turrets along the island of the battleship; five on the starboard side and five on the port. 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 ammunition storage for the 5-inch (127 mm)/54 cal gun was 500 rounds per turret, and the guns could fire at targets nearly 26,000 yd (24 km) away at a 45° angle. At an 85° angle, the guns could hit an aerial target at over 50,000 ft (15,000 m). The cancellation of the Montana-class battleships in 1943 pushed back the combat debut of the 5-inch (127 mm)/54 cal guns to 1945, when they were used aboard the US Navy's Midway-class aircraft carriers. The guns proved adequate for the carrier's air defense, but were gradually phased out of use by the carrier fleet because of their weight.(Rather than having the carrier defend itself by gunnery this would be assigned to other surrounding ships within a carrier battle group.) Anti-aircraft batteries: For the first time since the construction of the Iowa-class, the US Navy was not building a fast battleship class solely for the purpose of escorting Pacific-based aircraft carriers, and thus the Montana-class would not be designed principally for escorting the fast carrier task forces; nonetheless they would have been equipped with a wide array of anti-aircraft guns to protect themselves and other ships (principally the US aircraft carriers) from Japanese fighters and dive bombers. Oerlikon 20 mm anti-aircraft guns: The Oerlikon 20 mm anti-aircraft cannon was one of the most heavily produced anti-aircraft guns of World War II; the US alone manufactured a total of 124,735 of these guns. When activated in 1941, these guns replaced the .50 in (12.7 mm)/90 cal M2 Browning MG on a one-for-one basis. 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. Unlike other automatic guns employed during World War II, the barrel of the 20 mm Oerlikon gun does not recoil; the breechblock is never locked against the breech and is actually moving forward when the gun fires. This weapon lacks a counter-recoil brake, as the force of the counter-recoil is checked by recoil from the firing of the next round of ammunition. Between December 1941 and September 1944, 32% of all Japanese aircraft downed were credited to this weapon, with the high point being 48.3% for the second half of 1942. In 1943, the revolutionary Mark 14 gunsight was introduced, which made these guns even more effective. The 20 mm guns, however, were found to be ineffective against the Japanese kamikaze attacks used during the latter half of World War II. They were subsequently phased out in favor of the heavier 40 mm Bofors AA guns Bofors 40 mm anti-aircraft guns: Arguably the best light anti-aircraft weapon of World War II, the Bofors 40 mm anti-aircraft gun was used on almost every major warship in the US and UK fleet from about 1943 to 1945. Although a descendant of German, Dutch, and Swedish designs, the Bofors mounts used by the US Navy during World War II had been heavily "Americanized" to bring the guns up to the standards placed on them by the Navy. This resulted in a guns system set to British standards (now known as the Standard System) with interchangeable ammunition, which simplified the logistics situation for World War II. When coupled with hydraulic couple drives to reduce salt contamination and the Mark 51 director for improved accuracy, the Bofors 40 mm gun became a fearsome adversary, accounting for roughly half of all Japanese aircraft shot down between 1 October 1944 and 1 February 1945.
