M26 pershing: Tracing its evolution through specifications, variants, and remarkable operations

The M26 Pershing, named after General Pershing, was a powerful tank that played an important role in WWII and Korea. Weighing 92,355 pounds and equipped with a 90mm Gun M3, it came in a variety of configurations, which included the M26A1 and M46 Patton.

The M26 Pershing was a powerful heavy/medium tank that was used by the US Army. It was operational during the Korean War and was instrumental in the latter phases of World War II, especially in the invasion of Germany. Originally intended to replace the M4 Sherman, the M26 was given its name in remembrance of General John J. Pershing, the commander of the American Expeditionary Force during World War I. 

However, only a small number of Pershing tanks were used in combat in Europe because of a drawn-out development process. Although it was phased out in 1951 to make room for the better M46 Patton, which had a more powerful engine and more sophisticated suspension, the M26’s legacy was carried over into other tank models such as the M47 Patton, in addition to the continued impact it had on the designs of the M48 Patton and M60 tank.



The armoured vehicle exhibits a forceful presence on the battlefield due to its proportions and tremendous fighting weight of 92,355 pounds (41.9 tonnes). It is a commanding sight, measuring 20 feet 9.5 inches (6.337 metres) when the turret is facing aft and 28 feet 4.5 inches (8.649 metres) when it is facing forward. Its breadth is 11 feet 6 inches (3.51 metres), and its height is 9 feet 1.5 inches (2.781 metres). The vehicle has a formidable armour design with 102mm (4.0 inches) on the upper hull, 76mm (3.0 inches) on the lower hull, and turret sides, and 50–75mm (2.0–3.0 inches) on the hull sides. The crew of five members consists of a commander, gunner, loader, driver, and co-driver. 

The primary weapon is a powerful 90mm Gun M3 with an ample 70-round capacity. Secondary weapons such as the 550-round 1×.50 cal. M2 Browning machine gun and the 5,000-round 2×.30-06 M1919 Browning machine gun complements this. The driving force comes from a powerful Ford GAF 8-cylinder petrol engine that produces 450–500 horsepower (340–370 kW). The tank has a power-to-weight ratio of 11.9 horsepower per kg. A torsion bar helps with its suspension, which makes for good manoeuvrability. Its operational range reaches up to 100 miles (160 km), and its top speed on roads is 30 mph (48 km/h), while off-road it can reach up to 5.25 mph (8.45 km/h), solidifying its versatility in a variety of terrains.



Throughout development and post-war revisions, the M26 Pershing tank experienced many noteworthy changes. The M26, the first production variant, used an M3 rifle with a double-baffle muzzle brake. Later the M26A1 was released, which included a single-baffle muzzle brake, a bore evacuator, and an M3A1 gun. Based on the T26E1-1 pilot vehicle, the T26E4 received improvements including the T15E1 big outside stabiliser springs and single-piece ammunition before becoming the T26E4, which was used in battle.

With an enhanced mounting method that did away with the need for springs, the experimental T26E4 was equipped with a long T15E2 cannon and two-part ammunition. With a longer T54 cannon and single-part ammunition, the M26E1 appeared after the war. The M26E2, later designated as the M46 Patton, was equipped with an upgraded engine, gearbox, and M3A1 cannon. The T26E2 became the Medium Tank M45, standardising on a 105 mm howitzer and 74 rounds, and was designed as a close support vehicle.

Finally, the T26E5 prototype, which took influence from the heavily armoured M4A3E2 attack tank, displayed heavier armour, with a maximum thickness of 279 mm. Together, these differences demonstrate how the M26 Pershing tank has dynamically evolved and adapted to shifting battlefield conditions and technological breakthroughs.



During World War II, the Army Ground Forces’ resistance posed a major obstacle to the construction of the M26 Pershing tank. The Battle of the Bulge, however, revealed the shortcomings of the American tanks already in service, which led to the December 1944 deployment of T26E3 tanks—later renamed M26—to Europe. 310 Pershing tanks were eventually dispatched before VE Day, but only 20 made it to Europe before the war. On February 25, 1945, the M26 encountered the enemy close to the Roer River for the first time, demonstrating its combat effectiveness. 

On March 6, 1945, in a historic tank battle in Cologne, a T26E3 engaged a Panther tank and managed to penetrate and disable it. The M26 was instrumental in taking the Ludendorff Bridge in the Remagen Battle. In Europe, a variation known as the “Super Pershing,” which had frontal armour increased, battled German tanks and won multiple battles.

Twelve M26 Pershing tanks were sent to Okinawa in the Pacific in May 1945, but they didn’t arrive until after the war. During the Korean War, the M26 was also used and proved to be effective against North Korean tanks. However, due to its difficulties with movement in steep terrain, the M46 gradually replaced it.

Following the Second World War, M26s were sent to Europe to serve in police units. Furthermore, they were stationed in West Germany until M47 Pattons took their place. Through military aid programmes, Belgium, France, and Italy acquired M26s; Italy continued to use them until 1963.
