M-1070 Heavy Transporter Truck & M-1000 Trailer

The Heavy Equipment Transport System (HETS) consists of the M1070 Truck Tractor and the M1000 Heavy Equipment Transporter Semi-trailer. The HETS transports payloads up to 70 tons – primarily M1 Abrams tanks.

HETS operates worldwide on highways worldwide, secondary roads, and cross-country. The HETS has a number of features that significantly improve the mobility and overall performance of the system in a tactical environment. The M1070 tractor has front- and rear-axle steering, a central tire-inflation system, and cab space for six personnel to accommodate the two HETS operators and four tank crewmen. The M1000 semi-trailer has automatically steerable axles and a load-leveling hydraulic suspension.
