Ship details

Both Chrysler and General Motors supplied prototypes and the Chrysler model was selected for further development. Eventually the M1 Abrams entered U.S. service in 1980, ultimately replacing the M60 tank, which had seen two decades of service at the time.
Extensive improvements have been implemented to the latest M1A2 C and D versions such as improved composite armor, better optics, digital systems and ammunition.
The Abrams is equipped with a ballistic fire-control computer that uses user and system-supplied data from a variety of sources to compute, display, and incorporate the three components of a ballistic solution—lead angle, ammunition type, and range to the target—to accurately fire the main gun.
The fire-control system uses this data to compute a firing solution for the gunner. The ballistic solution generated ensures a hit percentage greater than 95 percent at nominal ranges.
