?The ''Montana''-class battleships of the United States Navy were planned as successors to the ''[[Iowa]]'' class, being slower but larger, better armored, and having superior firepower. This was the first class of battleships that were designed entirely free from treaty restrictions from the beginning. Five were approved for construction during World War II, but changes in wartime building priorities resulted in their cancellation in favor of the ''[[Essex]]''-class aircraft carriers and ''Iowa'' class before any ''Montana''-class keels were laid. With beams of 121 feet, they would have been the first U.S. battleships as originally designed to be too wide to transit the existing 110 foot wide locks of the Panama Canal. In conjunction with the ''Montana''-class, the Navy also planned to add a third set of locks to the Panama Canal that would be 140 ft (43 m) wide to enable ship designs with greater beam; these locks would have been armored and would normally be reserved for use by Navy warships.+The ''Montana''-class battleships of the United States Navy were planned as successors to the ''[[Iowa]]'' class, being slower but larger, better armored, and having superior firepower.

 Preliminary design work for the ''Montana''-class began before the US entry into World War II. The first two vessels were approved by Congress in 1939 following the passage of the Second Vinson Act. The Japanese attack on Pearl Harbor delayed construction of the ''Montana'' class. The success of carrier combat at the Battle of the Coral Sea and, to a greater extent, the Battle of Midway, diminished the value of the battleship. Consequently, though the design was finalized in 1942, the US Navy chose to cancel the ''Montana''-class in 1943 favor of more urgently needed aircraft carriers, amphibious and anti-submarine vessels. Because the ''Iowa''s were fast enough to escort the new ''Essex''-class aircraft carriers, their orders were retained, making them the last US Navy battleships to be commissioned. Preliminary design work for the ''Montana''-class began before the US entry into World War II.

 Compared to the high speed ''Iowa''-class that preceded it, the ''Montana''-class design returned to the US Navy tradition of emphasizing maximum firepower and protection while having only modest speeds. The ''Montana''-class would have been the largest, best-protected, and most heavily armed U.S. battleships ever, rivaling the Empire of Japan's immense ''[[Yamato]]''-class battleships. Compared to the high speed ''Iowa''-class that preceded it, the ''Montana''-class design returned to the US Navy tradition of emphasizing maximum firepower and protection while having only modest speeds.

?The armament would have been twelve 16-inch (406mm) Mark 7 guns in four triple turrets, up from the ''Iowas''’ three triple turrets of such guns. The secondary armament would have consisted of twenty 5"/54 Mark 16 dual purpose guns in ten mounts; compared to the old 5"/38 Mark 12, these new 5" (127mm) guns were longer and fired an heavier projectile, resulting in greater effectiveness and range against both air and surface targets. As designed, the light AA armament would have consisted of thirty-two 40mm Bofors guns and twenty 20mm Oerlikon guns, though these numbers would have substantially increased had the ships been completed.+The armament would have been twelve 16-inch (406mm) Mark 7 guns in four triple turrets, up from the ''Iowas''’ nine such guns in three triple turrets. The secondary armament would have consisted of twenty 5"/54 Mark 16 dual purpose guns in ten mounts; compared to the old 5"/38 Mark 12, these new 5" (127mm) guns were considerably longer and fired an heavier projectile at higher muzzle velocity, resulting in greater effectiveness and range against both air and surface targets.

?The propulsion system consisted of eight boilers providing steam for four turbines, with installed power of 172,000 SHP and a top speed of 28 knots. Compared to the ''North Carolina'', ''South Dakota'', and ''Iowa'' classes, the machinery spaces of the ''Montana''s featured extensive longitudinal subdivisions reminiscent of the arrangement found on the ''Lexington''-class battlecruisers; the designers had sufficient confidence in the stability characteristics to accept the risk of asymmetric flooding and include such longitudinal subdivisions.+The propulsion system consisted of eight boilers providing steam for four turbines, with installed power of 172,000 SHP and a design top speed of 28 knots.

Montana — American Tier X battleship.

One of the largest battleships in the world. She was slightly inferior to the Iowa-class ships in terms of speed, but had more main guns and significantly stronger torpedo protection. Montana’s armor was conventionally arranged and considerably reinforced.

Player Opinion

Performance

Tier X's Montana is, at first glance, basically a supersized Iowa with an additional triple mount turret and thicker belt and deck armor. Her offensive capability relies on her heavy broadside to smash enemy battleships or destroy anything smaller should the rounds connect. She has the heaviest broadside and the best dpm of any battleship in the game. While her guns are the smallest of the tier 10 battleships her American AP rounds do as much damage as the 420mm guns on the Kurfürst (while firing faster and more accurately) and exceed the AP damage of the Conqueror. Her HE rounds are also decent, but nothing special, characteristically weaker than IJN and RN HE but stronger than the high explosive found on German battleships. She also has an extremely powerful anti-aircraft suite and is more than capable of protecting herself from lower tiered aircraft carriers, but will likely require the assistance of teammates to fend off a determined strike by a Tier X flattop.

While she can reach a top speed of 30 knots, her large size and slow rudder shift time make her vulnerable to torpedo attack. Further, her main battery of 16-inch guns are not able to overmatch the 32mm thick bow armor found on most Tier IX and X battleships like Yamato’s main battery can. This means that Montana captains may sometimes be forced into firing high explosive shells at well-angled enemy battleships.

The dispersion of her main guns has been improved since the game launched, but her dispersion is still worse than Yamato’s even after the Artillery Plotting Room Modification 2 upgrade is installed. They are, however, more accurate than Großer Kurfürst’s main battery at range while having a slower turret traverse (45 seconds versus Kurfürst’s 40 seconds). Her secondaries are not as numerous as those of her Tier X counterparts, but they are better armored. This means that cruisers firing purely high explosive rounds are far less likely to destroy her secondary battery turrets, something that Yamato and Kurfürst cannot claim. Additionally, they have have the best rate of fire and the highest fire chance of all Tier X battleship secondary guns.

Montana is a ship that does not excel at any one thing for a battleship (most players don't count AA as it is purely a defensive ability). With that said, in a close-range fight she will easily outpace Yamato’s turret traverse (but not that of Kurfürst), while at range she will be more accurate than Kurfürst (but not as accurate as Yamato). Flexibility is her strength, but it is also her weakness.

Pros:

  • Twelve main battery guns generally means that something will hit even if a captain's aim is slightly off.
  • Can seriously damage destroyers without swapping ammunition simply due to volume of shells.
  • Phenomenal broadside killing power exceeds Yamato and can one-salvo anything that floats; losing or masking a turret still leaves her with Iowa broadside firepower.
  • One of the best anti-aircraft suites in the game.
  • Secondaries have the best fire chance (9%) and rate of fire (15 rounds per minute per gun) of Tier X battleships.
  • Quick turret traverse speed.
  • Two turrets still deliver 6 shells, allowing Montana to fire effective salvos at two targets simultaneously.
  • Faster than her Tier X counterparts.
  • Unparalleled flexibility when compared to her Tier X counterparts.

Cons:

  • Uses same guns as Iowa, no real upgrade for a ship one tier higher.
  • Dispersion is frustrating even with Artillery Plotting Room Modification 2 is equipped.
  • Very sluggish to accelerate.
  • Bow armor is overmatched by Yamato’s 460mm shells. Belt armor angling can still work but is shells will sometimes randomly sneak through anyway.
  • AA advantage is only useful in match that has carrier.
  • Largest citadel among tier 10 Battleships, though they are below the water line.

Research

As a Tier X ship, Montana doesn't have any upgrades to research.

Optimal Configuration

Upgrades

Maximizing Montana’s stealth is never a bad choice. With the Concealment Expert commander skill, Concealment Modification 1 in Upgrade Slot 6, and appropriate camouflage, her detection range drops down to 13.4 km. While still long enough for destroyers or cruisers to spot her before she is spotted, it gives Montana more leeway for turning due to the placement of her citadel. Steering Gear Modification 2 is recommended in Upgrade Slot 5 and will reduce her rudder shift time down to 17.8 seconds.

Upgrade Slot 3's best choice is Artillery Plotting Room Modification 2 to give her guns more accuracy; this will make it so that at ranges of ~12-13 kilometers Montana is exceptionally accurate, much more so than either of her contemporaries due to how dispersion works. In this configuration, she gives up damage to battleships that have equipped Main Battery Modification 3 to improve their rate of fire at the expense of her turret traverse. Main Battery Mod 3 will improve Montana’s damage-per-minute — already the highest of the Tier X battleships — and may surprise a cruiser who still expects her to be reloading.

Upgrade Slot 2 offers several options. AA Guns Modification 2 will boost her maximum AA bubble out to 6.2 km (7.5 km if stacked with the Advanced Firing Training commander skill), while Secondary Battery Modification 2 will boost the range and accuracy of her secondaries instead, and with captain skills and flags those can reach out to 9.1 km. Artillery Plotting Room Modification 1 will increase her already impressive range and give her secondaries a slight boost in range and accuracy, but is a weaker choice than the other two.

Upgrade Slot 1 is most commonly filled with Main Battery Modification 1, though Auxiliary Armaments Modification 1 is a popular pick for captains who go for a full AA build with her other upgrades and commander skills. Damage Control System Modification 1 is the easy pick for Upgrade Slot 4.

Commander Skills

Camouflage

Type 1, 2, or 5 camouflage can be equipped for credits; Types 2 or 5 are recommended at a minimum to reduce the accuracy of incoming shells.

Players who wish to spend doubloons can equip Montana with Type 20 camouflage that lowers her detection radius, reduces the accuracy of incoming shells, reduces her repair costs, increases her credit earnings, and increases the amount of experience she earns.
