M41 Walker Bulldog
The development of the T37 began in 1947 to replace the M24 Chaffee. The vehicle was designed to be air-transportable, and with heavier firepower, provided by an advanced 76 mm gun. In 1949, with the adoption of a less ambitious rangefinder, the project's designation was changed to M41. Production started in 1951 at Cadillac's Cleveland Tank Plant, and by 1953 the new tank completely replaced the M24 in the United States Army. It was later designated the M41 Walker Bulldog. The M41 was agile and well armed. On the other hand, it was noisy, fuel-hungry and heavy enough to cause problems with air transport.
The Walker Bulldog saw limited combat with the U.S. Army during the Korean War, but for the most part, the conflict served as a testing ground to work out the tank's deficiencies, especially with its rangefinder. At the time, it was designated as the T-41, and was rushed to the battlefield even before its first test run. This was due to the fact that the North Koreans were supplied with Soviet T-34 tanks, which were superior to the M-24.
