 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 would have been the US Navy's first class of true post-treaty battleships, 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.<br /> 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.

 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. As the ''Montana''-class were expected to regularly operate in a 27 knot battle line rather than with 30+ knot fleet carriers, the design reduced power output from 212,000 SHP to 172,000 SHP in 1941 to reduce some weight. 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.<br /> 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.

?Whereas the preceding ''South Dakota''-class and ''Iowa''-class were only designed to be protected from the regular 2,240 lb 16" Mark 5 shells, the ''Montana''-class armor scheme was designed to provide substantial protection zones against the newer and much more powerful 2,700 lb Mark 8 Superheavy Shells. With the beam restriction relaxed, the ''Montana''-class design returned to a more conventional external belt inclined at 19 degrees; the increased beam meant that the loss of waterplane area from external belt inclination was no longer a stability concern as it was for the ''South Dakota'' and ''Iowa'' classes. The main belt was 409mm thick cemented armor, with a separate lower belt 183mm thick mounted on one of the torpedo bulkheads. The horizontal protection consisted of a 57mm weather deck, 178mm main armor deck, and 19mm splinter deck. The traverse bulkheads were 457mm thick forward and 387mm thick aft. Turret protection was also increased over that of the ''Iowa''-class, with turret faces up to 572mm thick.+Whereas the preceding ''South Dakota''-class and ''Iowa''-class were only designed to be protected from the regular 2,240 lb 16" Mark 5 shells, the ''Montana''-class armor scheme was designed to provide substantial protection zones against the newer and much more powerful 2,700 lb Mark 8 Superheavy Shells.

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 X battleships her super-heavy shell (SHS) AP rounds do as much damage as the 420mm guns on Großer Kurfürst (while firing faster and more accurately) and exceed the AP damage of Conqueror. Her HE rounds are also decent, but characteristically weaker than Japanese and British 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 (Increases the firing accuracy of the main battery: -11% main battery dispersion.) 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 "jack of all trades" battleship. With that said, in a close-range fight she will easily outpace Yamato’s turret traverse, though not that of Kurfürst. While at range she will be more accurate than Kurfürst but not as accurate as Yamato. Flexibility is her strength.

Pros:

  • Having twelve 16-inch (406mm) main battery guns generally means that something will hit even if a captain's aim is slightly off and allows spreading fire at more angles for wild firing.
  • Can seriously damage destroyers with AP rounds simply due to the number of shells per volley.
  • 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.
  • Decent turret traverse speed.
  • Faster than her Tier X counterparts (except Republique).
  • Unparalleled flexibility when compared to her Tier X counterparts.
  • Can be fairly stealthy (13.4 km) when specialized for it (with Concealment System Modification 1 (Reduces the detectability range of the ship and aircraft carrier's squadrons: -10% to detectability radius. / +5% to the dispersion of enemy shells fired at your ship.) and Concealment Expert).
  • Legendary upgrade makes her even more agile and significantly reduces her vulnerability to fires and flooding.

Cons:

  • Uses same guns as Iowa, no damage per shot upgrade for a ship one tier higher (although having +3 more guns compensates for it).
  • Dispersion is frustrating even with Artillery Plotting Room Modification 2 (Increases the firing accuracy of the main battery: -11% main battery dispersion.) equipped.
  • Very sluggish to accelerate and vulnerable to collisions.
  • Bow armor can be pierced relatively easily by Yamato’s 460mm shells.
  • Largest citadel among Tier X battleships, though it is below the water line.
  • Legendary upgrade, while reducing damage suffered from critical effects, comes at the cost of either stealth or torpedo detection, reducing chances to avoid being hit.

Research

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

Optimal Configuration

Upgrades

Keep in mind that Montana can also be equipped with Spotting Aircraft Modification 1 (Increases the action time of the Spotting Aircraft and Rapid Takeoff Spotter consumables.: +30% action time.) in the Slot 1 to increase the spotter plane flight time.

Commander Skills

Consumables

Montana can equip the following consumables

It is advisable to equip Spotting Aircraft (While active, a spotter plane circles the ship enhancing main battery firing range.) than Catapult Fighter (While active, a group of fighter planes circles the ship providing protection by attacking incoming enemy aircraft.) as it adds more range and easier to shoot people behind covers.

As Montana is a high-tier ship, it is recommended to equip all consumables with premium ones: Damage Control Party II (When activated, instantly repairs fires, floods, and incapacitations, and prevents more for the duration.), Repair Party II (While active, restores a fixed percentage of a ship's hit points each second.), and Spotting Aircraft II (While active, a spotter plane circles the ship enhancing main battery firing range.).

Camouflage

Type 1, 2, or 5 camouflage can be equipped for Credits Credits; Types 1 or 5 are recommended at a minimum to reduce the detection range.

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