The M46 was an American medium tank designed to replace the M26 Pershing and M4 Sherman. It was one of the U.S Army's principal medium tanks of the early Cold War, with models in service from 1949 to the mid-1950s. It was not widely used by U.S. Cold War allies, being exported only to Belgium, and only in small numbers to train crews on the upcoming M47 Patton.

The M46 was the first tank to be named after General George S. Patton Jr., commander of the U.S. Third Army [3] during World War II and one of the earliest American advocates for the use of tanks in battle. [4] [5]

History

After World War II, most U.S. Army armored units were equipped with a mix of M4 Sherman and M26 Pershing tanks. Designed initially as a heavy tank, the M26 Pershing tank was reclassified as a medium tank postwar. The M26 was a significant improvement over the M4 Sherman in firepower and protection. Its mobility, however, was deemed unsatisfactory for a medium tank, as it used the same engine as the much lighter M4A3 and was plagued with an unreliable transmission.

Work began in January 1948 on replacing the original power plant with the Continental AV1790-3 engine and Allison CD-850-1 cross-drive transmission. This design was initially called the M26E2, but modifications continued to accumulate; eventually, the Bureau of Ordnance decided that the tank needed its own unique designation. When the rebuild began in November 1949, the upgraded M26 received not only a new power plant and a main gun with a bore evacuator, but a new designation M46. In total, 1,160 M26s were rebuilt: 800 to the M46 standard, 360 to the M46A1.
