The M1 Abrams is a third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems)[9] and named for General Creighton Abrams. Conceived for modern armored ground warfare and now one of the heaviest tanks in service at nearly 68 short tons (almost 62 metric tons), it introduced several innovative features, including a multifuel turbine engine, sophisticated Chobham composite armor, a computer fire control system, separate ammunition storage in a blow-out compartment, and NBC protection for crew safety. The M1 Abrams was developed from the failure of the MBT-70 project to replace the obsolescent M60 Patton. There are three main operational Abrams versions, the M1, M1A1, and M1A2, with each new iteration seeing improvements in armament, protection, and electronics. Extensive improvements have been implemented to the latest M1A2C and D (formerly designated M1A2 System Enhancement Package version 3 or SEPv3 and M1A2 SEPv4, respectively) versions such as improved composite armor, better optics, digital systems and ammunition.
