The M1A1 Battle Tank was a silent and unstoppable force in the Persian Gulf. Giving it the power, speed, quick acceleration and quiet operation was the AGT1500 turboshaft engine from Honeywell.

With over 24 million operating miles worldwide, the AGT1500 has become the heartbeat of the Abrams family of battle tanks. Its compact design, cold-starting, instant power, multifuel capabilities and stealthy operation are just part of what makes this engine the world standard for tank durability and survivability.

Thanks to its simple modular design, operational readiness for the AGT1500 engine is outstanding. Unlike a diesel, which has to be serviced as a whole engine, the AGT1500 can easily be separated and serviced in the field, keeping more vehicles operating.

With the AGT1500's Digital Electronic Control Unit (DECU), you get operational diagnostic capability which results in 30% less maintenance time and 20% lower idle fuel consumption.

Contrast these features with a diesel engine which is noisy, smoky, requires a cooling system (space and power loss), a heater, a warm up period, and has more moving parts to wear out. Quite simply, there's no comparison.

Honeywell's ongoing development and modernization programs for the AGT1500 turboshaft engine are paving the way toward 21st century reliability. Our defined concepts will decrease operating temperature while select component durability will double through our Improved Durability Program. Further durability improvements are being obtained by the Partnership to Reduce Operating and Support Engines (PROSE) costs program. This is a teaming arrangement between TACOM, ANAD and Honeywell whose ultimate goal is to reduce the engine costs.
