The Army is exploring the possibility of developing a 60-ton Abrams main battle tank that provides as much protection as the current 75-ton version, reports Army Times.
Plans to lighten the vehicle complement an existing Army effort to build prototypes of a tougher, more high-tech M1A3 Abrams main battle tank by 2014, with an aim to field it by 2017. The US Army plans to keep the Abrams MBT in the field through 2050.
