We don’t user the M-60 any more but we made 15,000 of them. Pull them off the used car lot and send them to Ukraine.
I think most M60 series were sold or scrapped.
US has @2500 M1 series assigned to the 20 divisions of the Active Army and the National Guard, or in prepositioned storage around the world. And another 3,700 in reserve. Unlike the M60, the M1 chassis was designed to be at least somewhat modular and upgradable, so the maintenance and upgrade potential is always there.
Thats an enormous number of first line tanks.
I have fond memories of training with the M60-A1-Rise main battle tanks. But one of the advantages of the Abrams is that it can continue operating after taking hits from weapons like RPG-7s and other HEAT rounds that would cause a catastrophic kill on an M60 . The Abrams has twice the cross country speed and is much more survivable. It out classes all common Russian tanks and thus provides a psychological advantage to its crew.
Many of our M60s were dumped offshore as part of an artificial reef program.
