Sadly the M1 is a 30 year old design that is in need of a replacement. Just too many of them to make a replacement a simple matter.
The real strength of the Abrams is it's computer systems: vision, targetting, tracking, and communication. Which I assure you are the best money can buy.
Even the ammunition and armor have been upgraded.
The fact that the main chassis is 30 years old means next to nothing.
