This installment in R. P. Hunnicutt's ambitious 10-volume series on the history of American tanks covers the development of the American main battle tank from its conception in the 1950s through the production and standardization of the M1 Abrams main battle tank. In the 50s, as the M48 Patton was gearing up for production, there was a great deal of interest in developing new design concepts for future armored fighting vehicles; many of these ideas made up the early foundations of the tank that would become the M1 Abrams 30 years later.
