Possible XM1202
The U.S. Army has plans to continue the M1, though at one point, they thought about replacing it with the Future Combat Systems XM1202 Mounted Combat Systems, but DoD’s budget was cut ending development and funding for the program. As mentioned previously, the M1A3 was also early in it was design period in 2009. Prototypes were planned to begin testing in 2014 and combat in 2017. Instead, a new version of the M1A2 SEP v4 is scheduled to start testing in 2021. As of 2020, the M1A2 service will remain in service beyond 2050.
