Montana Class (BB-67 through BB-71)
1941 Building Program. Construction cancelled 1943.

The five battleships of the Montana class, authorized under the 1940 "Two Ocean Navy" building program and funded in Fiscal Year 1941, were the last of their kind ordered by the U.S. Navy. With an intended standard displacement of 60,500 tons, they were nearly a third larger than the preceding Iowa class, four of which were the final battleships actually completed by the United States. The Montanas were intended to carry twelve 16"/50 guns, three more than the earlier class. Protection against underwater weapons and shellfire was also greatly enhanced. They would have been the only new World War II era U.S. battleships to be adequately armored against guns of the same power as their own. To achieve these advances, the Montana class was designed for a slower maximum speed than the very fast Iowas and had a beam too wide to pass through the existing Panama Canal locks.

Completion of the Montana class would have given the late 1940s U.S. Navy a total of seventeen new battleships, a considerable advantage over any other nation, or probable combination of nations. The Montanas also would have been the only American ships to come close to equalling the massive Japanese Yamato. However, World War II's urgent requirements for more aircraft carriers, amphibious and anti-submarine vessels resulted in suspension of the Montanas in May 1942, before any of their keels had been laid. In July 1943, when it was clear that the battleship was no longer the dominant element of sea power, their construction was cancelled.

The Montana class would have consisted of five ships, to be constructed at three Navy Yards:

  • Montana (BB-67), to be built at the Philadelphia Navy Yard, Pennsylvania
  • Ohio (BB-68), to be built at the Philadelphia Navy Yard
  • Maine (BB-69), to be built at the New York Navy Yard, Brooklyn, New York
  • New Hampshire (BB-70), to be built at the New York Navy Yard
  • Louisiana (BB-71), to be built at the Norfolk Navy Yard, Portsmouth, Virginia.

Montana class design characteristics:

  • Displacement: 60,500 tons (standard); 70,965 tons (full load)
  • Dimensions: 921' 3" (length overall); 121' 2" (maximum beam)
  • Powerplant: 172,000 horsepower steam turbines, producing a 28 knot maximum speed
  • Armament (Main Battery): Twelve 16"/50 guns in four triple turrets
  • Armament (Secondary Battery): Twenty 5"/54 guns in ten twin mountings (ten guns on each side of the ship)

The following images represent preliminary design plans prepared in early 1940 as part of the Montana class design development process. At that time, it was intended that the first ship of this class would have hull number BB-65. None of these plans represent the design finally adopted for the Montana class.

"Battleship Study - BB65 - Scheme 3 - (1940 Studies)"


Preliminary design plan prepared for the General Board as part of the process leading to the Montana class (BB-67--71) battleship design.
This plan, dated 6 February 1940, is for a ship of 52,500 tons standard displacement and 64,500 ton trial displacement, with a main battery of twelve 16"/50 guns, a secondary battery of twenty 5"/38 guns and a 130,000 horsepower powerplant for a speed of 28 knots. Ship's dimensions are: waterline length 860'; waterline beam 114'; draft 36'. Scale of the original drawing is 1/32" = 1'.
Port side 5" gun arrangement is labeled "previous secondary battery arrangement". Starboard side has a "proposed secondary battery arrangement."

The original plan is in the 1939-1944 "Spring Styles Book" held by the NHHC.

The following image represents a preliminary design plan prepared in mid 1940, comparing the Montana class hull profile with that of the Iowa (BB-61) class.

"Battleship Study, BB 65 - Scheme 1 and BB 61-64 (Incl{usive})"


Preliminary design plan prepared for the General Board comparing the outboard profile (including superstructure) of the Iowa (BB-61) class battleships with the hull profile of the Montana class.
This plan is dated 9 July 1940 and shows the Iowa class outboard profile in solid lines and the hull of the Montana class in dashed lines.
At the time, the Montana class was planned to begin with hull number BB-65, rather than BB-67 as it became after two more Iowas were ordered as BB-65 and BB-66.
Scale of the original drawings is 1/32" = 1'.

The original plan is in the 1939-1944 "Spring Styles Book" held by the NHHC.
