The U.S. Army is pushing ahead with plans for a next-generation M1 Abrams main battle tank, which the service is calling "M1E3," having now decided to axe development of the M1A2 System Enhanced Package Version 4 (SEPv4).
According to the service, the move away from SEPv4 relates to the need for tanks with increased mobility and survivability, in light of the war in Ukraine, with lighter-weight, more adaptable systems required on the battlefields of 2040 and beyond. It’s unclear at present how the Mobile Protected Firepower (MPF) light tank initiative factors into this decision, if at all.
The Army announced its intention to pursue a more ambitious modernization strategy for the M1 earlier this week. “The new approach balances costs with the Army’s needs and invests in the nation’s defense industrial base,” it said. Initial operational capability (IOC) of the M1E3 is anticipated by the early 2030s. Despite the designation having been used by the service to describe various future ‘modernized’ Abrams concepts since at least 2010, it notes that “the M1E3 Abrams nomenclature is a return to the Army’s standard use of its type classification and nomenclature system for our combat vehicle fleet.” The ‘E’ especially is used to illustrate the significant engineering changes involved compared to the previous system, and the type’s prototype status, per the service.
“The development of the M1E3 Abrams will include the best features of the M1A2 SEPv4 and will comply with the latest modular open systems architecture standards, allowing quicker technology upgrades and requiring fewer resources,” the Army says.
