T32

T32. The T32 was an American heavy tank prototype developed in the closing stages of World War II as a potential counter to advanced German armour like the Tiger II. Designed with exceptionally thick, sloped armour and a high-velocity 90 mm gun, it represented a significant departure from earlier United States Army designs such as the M26 Pershing. Although it never entered mass production, the T32 provided critical engineering data that influenced the development of postwar American tanks, including the M103.

History

The T32 program originated in mid-1944 from the Ordnance Department's urgent requirement for a tank with superior firepower and protection, driven by combat reports from the European theatre of World War II. Initial design studies, designated T29 and T30, focused on mounting larger 105 mm and 155 mm guns, but the T32 was conceived as a more balanced design using the powerful 90 mm T15 gun. Development was authorized in February 1945, with Chrysler awarded the contract to build pilot models at the Detroit Arsenal Tank Plant. The project proceeded even as the war in Europe concluded, with the first prototypes completed after Victory over Japan Day, as the U.S. Army shifted its focus to evaluating future armored vehicle needs during the early Cold War.

Design and specifications

The T32's design was heavily based on the M26 Pershing but extensively modified for increased survivability. Its most notable feature was the cast, homogenous steel armour, with the glacis plate sloped at 54 degrees and reaching an effective thickness of 298 mm, making it nearly impervious to contemporary anti-tank guns. The tank was armed with the long-barreled 90 mm T15E2 gun, capable of firing APDS ammunition to penetrate heavy armour at long range. Power was supplied by a fuel-injected, 770 hp Ford GAC V-8, linked to a CD-850 cross-drive transmission, a combination that improved reliability over earlier tanks. The vehicle utilized an advanced torsion bar suspension system with eight road wheels per side, derived from the T20 Medium Tank series, to support its 58-ton weight.

Operational history

The operational history of the T32 was confined to extensive testing and evaluation by the U.S. Army. All four prototypes underwent rigorous trials at the Aberdeen Proving Ground in Maryland and the Fort Knox military reservation in Kentucky from 1946 to 1948. The tests revealed that while the tank's armour and firepower were exceptional, its mobility and strategic transportability were hampered by its extreme weight and width. With the postwar drawdown and the emergence of new anti-tank threats, the Pentagon concluded that the Soviet Union's IS-3 heavy tank necessitated an even more powerful weapon system. Consequently, the T32 project was terminated in favor of the larger T29 and T30 programs, and ultimately the M103.

Variants

Only two distinct variants of the T32 were built, differing primarily in their secondary armament and minor details. The **T32** was the base model, featuring a coaxial .30 caliber M1919 Browning machine gun and a .50 caliber M2HB mounted on the commander's cupola. The **T32E1** was a modified pilot model that replaced the commander's cupola machine gun with a second .50 caliber M2HB mounted in a remote-controlled blister on the turret roof, intended to improve anti-aircraft capability. No other major variants were developed, as the project was canceled before further iterations could be proposed.

Operators

The only operator of the T32 was the United States Army, specifically its testing and evaluation branches. The tanks were never issued to any frontline units such as the 1st Infantry Division or the 3rd Armored Division, nor were they deployed to theaters like Korea during the Korean War. Following the cancellation of the program, the prototypes remained at various test facilities, including the Yuma Proving Ground, and were eventually scrapped or placed in museum collections, such as the National Armor and Cavalry Museum at Fort Benning.
