Description

The Heavy Expanded Mobility Tactical Truck (HEMTT) is a family of heavy, multi-purpose, tactical trucks developed by Oshkosh Truck Corporation to meet the needs of the United States Armed Forces. This family of tactical trucks comprises the M977 cargo with crane, M978 2,500-gallon fuel tanker, M983 tractor, M9841A1 wrecker and/or M985 cargo with heavy crane. All of them are based on 8x8 chassis prime mover featuring high mobility and capacity for carrying 10+ tons payloads. HEMTT can be deployed anywhere in the world by C-130 Hercules, C-17 Globemaster III and C-5 Galaxy tactical and strategic transport aircraft. Oshkosh Truck Corporation has developed many variants of HEMTT to fulfill the needs of the US Armed Forces Services. HEMTT-LHS or Heavy Expanded Mobility Tactical Truck-Load Handling System was developed to perform resupply and related missions at the brigade and battalion level. HEMTT-LHS features an integral load handling system which reduces crew workload thanks to self-load/unload capability. It is capable of carrying 11-ton payloads plus another 11-ton on a towed trailer. This variant was introduced in 2000 and is used to carry equipment, ammunition and/or supply. HEMTT-LHS was selected as the basis for THAAD air defense system missile launcher. It reached initial operational capability with 296th brigade support battalion based at Fort Lewis, Washington, in March 2001. HEMTT-CBT (Common Bridge Transporter) is a variant designed to transport and deploy bridges in support of military units. HEMTT-TFFT (Tactical Fire Fighting Truck) based on M977 chassis features a 1,000-gallon (3,800 liters) water tank, foam system, a 500 gallon-per-minute (gpm) roof turret, and 250 gpm bumper turret. TFFT also features special fire protection for the crew, ammunition and fuel load. HEMTT A3 was introduced in February 2005 featuring ProPulse diesel-electric engine which provides 20 percent fuel economy savings. In addition to the hybrid drive, third generation HEMTT features other improvements such as independent suspension, networked truck diagnostics system, 13-ton payload capacity and improved load handling system. HEMTT A3 hybrid drive can perform as electrical power generator and can be replaced in just 30 minutes. HEMTT was due to undergo an 18-month extensive performance and durability testing to be complete before the end of 2006. To date, the HEMTT tactical truck system has been purchased by the United States Army with the first truck delivered in 1982 from an order for approximately 5,000 such vehicles. These vehicles are powered by a single Detroit Diesel 8V-92TA engine developing 445-hp.
