Summary

The AGT-1500 gas turbine has powered the M1 Abrams for over four decades. The maintenance workforce — in organic units, at sustainment brigades, and at Anniston Army Depot — has built its technical baseline around this engine. The planned transition to a new powerplant for the M1E3 creates a workforce readiness problem that current transition planning does not adequately address. This brief examines the training, tooling, and technical manual requirements and assesses the timeline risk.
