A variant of the Chrysler XM1 Abrams serving as a technology demonstrator, the XM1A is an American main battle tank equipped with the Rheinmetall Rh-120 Tank Gun, full NBC sealing, remote weapon station for the commander, bleeding-edge satellite navigation equipment and a digital data bus that transmits data within the tank and across the battlefield. It is being developed by DARPA in conjunction with Chrysler, and considered by American strategists to be the most advanced armoured vehicle in the planet, even factoring potential Soviet developments like the ultra-secretive Object 219U (T-80U).
