The Enhanced Heavy Equipment Transporter System (EHETS) will replace the Heavy Equipment Transporter System (HETS) and consists of an M1300 tractor (M1070A1 modified to reduce and relocate weight to achieve European road permits) and an eight-axle M1302 trailer capable of worldwide transport. The EHETS primary mission is to transport an M1 series Main Battle Tank (MBT) and other tracked vehicles weighing up a minimum of 82 tons and up to 90 tons. It is able to self-load/unload disabled vehicular cargo for evacuation purposes.  The system will provide line haul, local haul, and maintenance evacuation of heavy tracked vehicles during tactical operations on primary and secondary roads worldwide.


The EHETS is used primarily to transport MBTs and other heavy equipment weighing a minimum of 82 tons and up to 90 tons, and is capable of attaining highway permits (at a reduced payload) to allow transport within European countries. It will carry the heaviest current and future versions of the M1 Abrams Main Battle Tank. The EHETS will conduct transport of heavy combat units from sea and air ports of debarkation into corps and division areas. The EHETS can also deliver equipment and cargo along Main Supply Routes (MSR) as far forward as mission, enemy, terrain and weather considerations allow.

This includes a modification of the M1070A1 tractor into the M1300 configuration and procurement of a modified commercial trailer, the M1302.
  • The EHETS will replace the legacy HETS to fill multiple identified capability gaps. It is in the pre-Materiel Development Decision phase. The December 2019 Army Requirements Oversight Council (AROC) approved the requirement and the procurement quantities of the new system, which will include M1300 tractors as the prime mover, and a commercially based trailer. The USAREUR HETS ONS M1300 and M1302 trailer is part of the enduring EHETS capability.
