The M46 was an improved
M26 Pershing(sometimes named Pershing II) tank and one of the U.S army's principal main battle 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 M-47. The M46 tank was designed to replace the previous M26 Pershings and M4 Shermans.
World War IImost US Armyarmored units were equipped with a mix of M4 Shermanand M26 Pershingtanks.
Designed initially as a
heavy tank, the M26 Pershingtank was reclassified as a medium tankpostwar. 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 that powered the much lighter M4A3. Its underpowered engine was also plagued with an unreliable transmission.
Work began in January 1948 on replacing the original power plant with the Continental AV-1790-3 engine and Allison CD-850-1 cross-drive transmission. The design was initially called M26E2, but modifications continued to accumulate, and 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
bore evacuator, but a new designation along with a name - simply M46. In total 1,160 M26s were rebuilt: 800 to the M46, 360 to the M46A1 standard.
The only extensive combat use of the M46 was in the
Korean War. The tank proved superior to the much lighter North Korean T-34-85, which were encountered in relatively small numbers. M46s formed about 15% of US tank strength in Korea; the majority of tanks in service in Korea were M4 Shermans. The M46 was in the early fifties for training purposes leased for free in small numbers to some European countries, including Belgium, Franceand Italy, in preparation of the introduction of the M47. US instruction teams used the vehicles to train European tank crews and maintenance personnel.
