Heavy Expanded Mobility Tactical Truck (HEMTT)






The Heavy Expanded Mobility Tactical Truck (HEMTT) is an eight-wheel drive, diesel-powered, 10-short-ton (9,100 kg), tactical truck used by the US military and others. In evolving configurations, it has been in continuous production since 1982. The M977 HEMTT entered service with the U.S. Army as a replacement for the M520 Goer.

By early 2015, more than 27,000 HEMTTs in various configurations had been produced by Oshkosh Defense through either new-build or re-manufactured. Current variants have the A4 suffix.

The 10×10 Oshkosh Logistic Vehicle System Replacement (LVSR) is the U.S. Marines’ equivalent to the U.S. Army’s Oshkosh 8×8 HEMTT and Oshkosh 10×10 Palletized Load System (PLS). The Marines do not use the HEMTT or PLS, and the Army does not use the LVSR, but both services use a common trailer (M1076) with all three truck types.

The HEMTT's objective is to provide heavy transport capabilities for supply and re-supply of combat vehicles and weapons systems. Compared to earlier generation 5-ton trucks in U.S. Army service it offers increased payload and mobility. The HEMTT is available in a variety of configurations, including cargo, tanker, tractor and wrecker.

The HEMTT was developed from the outset as a tactical truck, but to minimize procurement and life cycle costs included militarized commercial automotive components where possible, these including the engine and transmission. Some components used in early HEMTTs are common with the Oshkosh Logistics Vehicle System (LVS) vehicles which were supplied to the U.S. Marine Corps. More details
