Navy Mistake? The Montana-Class Battleships Could Have Been a Game Changer


Of all the battleships that served in the illustrious history of the U.S. Navy, the Iowa-class battleships are undoubtedly the most famous, thanks in no small part to two factors. They were the last battleships of any nation to fire their guns in anger, namely during Operation Desert Storm in 1991. The Japanese surrender during WWII was hosted by an Iowa-class BB, the U.S.S. Missouri (BB-63), affectionately nicknamed “The Mighty Mo.” But had historical fate taken a different twist, the Mighty Mo and her sister ships might have been supplanted in fame and prestige by “The Mighty Monty,” i.e. the Montana-class battleships (No pun intended with “Monty” vis-a-vis Montgomery Burns from The Simpsons, Field Marshal Bernard Law Montgomery, or the movie The Full Monty, by the way). 

A Capital Ship for an Ocean Trip…

Though they were ultimately never actually produced, the Montana-class battleships were the last battlewagons ever to be ordered by the U.S. Navy, authorized under the “Two Ocean Navy” building program and funded in the Fiscal Year 1941. These ships were nearly a third larger than the preceding Iowa-class, at 921 feet (280.41 meters) in length and with a beam of 121 feet (36.88 meters), and a displacement of 60,500 tons—nearly 71,000 tons with full war load. For a basis of comparison, the Imperial Japanese Navy’s (IJN) Yamato and Musashi were still slightly heavier at 72,809 tons fully laden and wider abeam at 128 feet (38.9 meters) but shorter in hull length at 862 feet (233 meters). The IJN’s super-BBs still had the biggest guns, at 18.1 inches (46 cm), as the Montanas would have retained the 16-inchers (40.64 cm) of the Iowas, but with an added twist: three extra such guns, for a dozen in total, and increased armor—21,000 tons with bulkheads at 18-inches of plating—for good measure.

A total of five of these behemoths were ordered, with the namesake in her class (BB-67) to be built at the Philadelphia Navy Yard along with the Ohio (BB-68); whilst Maine (BB-69) and New Hampshire (BB-70) were to be constructed at the New York Navy Yard in Brooklyn; and the Louisiana (BB-71) at the Norfolk Navy Yard in Portsmouth, Virginia. The Navy would eventually resurrect the Ohio moniker for its ballistic missile submarine (SSBN) class, but that’s a different story.

Although the Montanas would not have one-upped Yamato and Musashi in terms of the main gun bore size, the American’s 16-inch/50-caliber guns were indeed no slouch in terms of accuracy, power, and range, as they could lob 2,700-pound (1224.69 kg) shells over an astonishing distance of up to 23 miles (37 km). Each gun took dozens of sailors to fire, and these dozens of sailors in turn comprised just a small fraction of the total crew complement of 2,355 enlisted sailors and commissioned officers. The “dirty dozen” (so to speak) main guns were in turn backed up by a secondary battery of twenty 5-inch (12.7 cm)/38-caliber guns – the standard bore size for the main guns on U.S. Navy destroyers (DDs) and destroyer escorts (DEs) at the time.

Very impressive stats. So then, what killed the Montanas in their proverbial womb?

Le Morte d’Montana

For starters, with all that extra firepower and bulk also came extra expense, in terms of fun and maintenance. Moreover, as noted by my 1945 colleague Brent M. Eastwood, “The Navy was also willing to roll with the punches and react to modern trends in warfare. The airplane and the aircraft carrier proved to be more important and vital compared to the battleship. A squadron of dive bombers could menace these big ships to the point of full destruction. Ship on ship warfare was also changing. The Navy had assumed before the war that battleships would use their decisive power to eliminate the maximum amount of enemy shipping.  Enemy submarines were also always dangerous, and a launch of numerous torpedoes at once could endanger the battleship – no matter how thick the armor.”

Last but not least, the death knell of the Montana-class was sounded by its speed, or lack thereof, 28 knots compared with the 33-knot maximum speed capability of the Iowas. As 1945 colleague Peter Suciu states, this was “not fast enough to escort carriers, but still fast enough to operate in the battle line. Given the threat of enemy aircraft, especially in how the Royal Navy’s HMS Prince of Wales and HMS Repulse were sunk off the coast of Singapore in December 1941 – less than a year after she was commissioned – by torpedo aircraft, the slower speed was an issue.”  Given how these sinkings comprised arguably the single darkest day in the history of the Royal Navy, this was no mere trifling consideration for Britain’s American allies.

I Would Like to Have Seen Montana…

With all of those factors weighing in upon the decision, the Navy canceled the Montana program on 21 July 1943. But had those Navy planners been in possession of a crystal ball and thus been able to foresee the Iowa-class battleships’ new leases on life as Earth-shattering shore bombardment platforms during the Korean War, Vietnam War, Lebanon, and first Iraq conflicts alike, who knows if those decision-makers might’ve changed their minds?

    The mistake was building Battleships in the first place. America only built them because of the sunk costs and WW2 didn’t happen yet.

    I wonder how much political pressure the USS Iowa gun turret explosion (April 89) brought upon the Navy to decommission its remaining Battleships.Nice work Chris.

    The Montana class could be viable with redesigned hull form and nuclear power. Probably capable of close to 40 knots. Keep the 16″ main battery and all the associated armor but replace the 5″ with Aegis missles, CIWS, Tomahawks, Harpoons. ASW helicopters and you would have an all purpose platform that would be a survivable and valuable asset.

    Ok recently built a 1/350 scale model of Montana. I used the 16 inch fit which came wth the kit although guns at 18 inch were potentiall avauilable see the collection at Dam Neck. Issue was size of weapons on Yamato–not really known at the time. Thought 16 inch. The other guns were listed as early 5 inch 54s some of which endedup on the FDR class carriers and oddly enough n the first MSDF Japanes post war DDS. The armor and firepower of these ships would have been seriously useful in the post war period as 27 knots was a good fleet speed, except for carrier ops. Now the big deck aomphibs dont do much mroe than that anyway. The other interesting thisng was the possiblity fot tem haveing the rada directed 3 inch 50 AA batteries as well as the huge 20 mm close in defenses. Again, radar directed and optical capaablities for the entie battery needs to be taken into account. My model which was I think produced byt he Koreans has mounts for 22 /3 inch 50s. For more oin this see Norman Friedmans US Bayttleships or later literature. Were such a ship to exist today, starting with the armor and replacing the steam turbines with gas turbines (no boilers needed) gp gun with 5 inch 62s and repolace main battery with rail guns *no dangerous powere needed for inert projectiles and incorporate the CVAN hull designs defensive protections ( America was almost impossible to sink) Alos lots of Lser mounts to cover 360 vbaked up by CIWS) Helos and drones for ASW. Even at 600000 a shot the rail guns are cheaper than new harpoons and have an equivalent range and desrtucitve power as 16 inch shells. Also could carry the longer range new cruise kissles and break any bliockade in the world. QWHatever the fit there is a need for alarge surface combatant to protect the carriers Burke class flight 3 are good but still have a glass jaw…best old MBA from USS Harwood (DD861)
