The M59 was an American armored personnel carrier that entered service in the spring of 1954 replacing the M75. It had three key advantages over the M75: it was amphibious, had a lower profile, and was considerably cheaper to produce. Production ended in 1960, by which time approximately 6,300 had been built. The M84 Mortar Carrier was a derivative of the M59. The M59 was replaced in service by the M113 family of vehicles.
