M1070A1/M1000 Heavy Equipment Transporter System (HETS)
The M1070A1/M1000 Heavy Equipment Transporter System (HETS) deploys transports, recovers and evacuates M1 tanks and other vehicles of similar weight to and from the battlefield. The M1070A1 tractor and M1000 semitrailer replaced the M911/M747. The M1070A1/M1000 HETS was developed to accommodate the 70 ton weight of the M1 Abrams family of main battle tanks. The M1070A1 provides line-haul, local-haul and maintenance evacuation on and off the road during tactical operations worldwide. The HETS is designed to carry both the tank and its crew.
The M1070A1 HETS tractor was designed with a new power train that consists of a 700 horsepower engine, single-speed transfer case for ease of operation, and numerous front suspension and drive system updates to increase the safe operating load capacity of the vehicle steering and handling systems. The M1070A1 is designed to accept the HET Urban Survivability Kit (HUSK) armored cab.
The M1000 Semitrailer has been improved with a series of maintainability changes including self-adjusting brakes, central lubrication system at each axle, and a more reliable hydraulic pump.
M1300/M1302 Enhanced Heavy Equipment Transporter System (EHETS)
The M1300/M1302 Enhanced Heavy Equipment Transporter System (EHETS) deploys transports, recovers and evacuates the heaviest M1 Abrams tank and other combat vehicles of similar weight to and from the battlefield. The M1300 tractor and M1302 trailer will replace M1070A1/M1000 as the Army’s modernizes the Heavy Equipment Transporter fleet. The M1300/M1302 EHETS was developed to accommodate the 82 ton weight of the M1 Abrams family of main battle tanks and meet European highway requirements. The M1300 tractor provides line-haul, local-haul and maintenance evacuation during tactical operations worldwide. The EHETS is designed to carry both the tank and its crew.
The M1300 tractor is a modified M1070A1 HET tractor. The M1300 tractor consists of weight reduction and powertrain upgrade modifications. The powertrain upgrade includes a two-speed transfer case to increase towing capacity and reliability. The M1300 is designed to accept the HET Urban Survivability Kit (HUSK) armored cab.
The M1302 trailer is a new production 8 axle, flatbed trailer with automatic rear ramps.
M977A4 Armored Heavy Expanded Mobility Tactical Truck (HEMTT)
The HEMTT is used as a prime mover for the Patriot missile system, M7 forward repair system and tactical water purification system and as the chassis for the M1977 common bridge transporter, M1142 tactical fire fighting truck and M1158 HEMTT-based water tender. The HEMTT is also compatible with the PLS trailer.
The HEMTT is augmented by the M989-A1 heavy expanded munitions ammunition trailer (HEMAT) in the transport of the Multiple-Launch Rocket System (MLRS) family of munitions (MFOM). The HEMAT can transport four MFOM pods, each weighing approximately 5,400 pounds. The off road capability of the HEMTT and HEMAT combination can transport eight MFOM pods. The M989A1 HEMAT is also required to transport six standard ammunition pallets (single stacked), two 600-gallon fuel pods or two 500-gallon fuel bladders.
M1075A1 Armored Palletized Load System (PLS)
The Palletized Load System (PLS) is the primary component of the maneuver-oriented ammunition distribution system. It also performs local-haul, line-haul, unit resupply and other transportation missions in the tactical environment. In addition the PLS is the prime mover for the M7 Forward Repair System and various engineer mission modules (M4 Bituminous Distributor Module, M5 Concrete Mobile Mixer Module and M6 Dump Body Module). The PLS is the host chassis for the dry support bridge launcher vehicle (M1975).
The PLS consists of a 16.5-ton payload tactical truck with a flatrack. It is a five-axle, 10-wheel drive vehicle with a 500-hp Detroit Diesel engine, an Allison automatic transmission and a CTIS. This combination provides a highly mobile system able to transport its payload in virtually any type of terrain or weather and maintain pace with the self-propelled artillery systems that it supports. The PLS comes in two mission-oriented configurations: the M1074 and the M1075. The M1074 is equipped with a variable reach materiel-handling crane (MHC) to support forward-deployed field artillery units. The M1075, without MHC, is used in conjunction with the M1076 trailer to support transportation line-haul missions.
The PLS recapitalization (RECAP) program will recapitalize PLS vehicles to 0 miles/0 hours and to the current A1 configuration, which consists of bumper-to-bumper recap of the entire truck with the following technology insertions: CAT 15 engine, electronic transmission, ABS and traction control, and larger cab. The PLS A1 is designed with an armored A-kit cab and B-kit armor.
M1076 PLS Trailer
The M1076 PLS trailer is a three-axle, wagon-style trailer with a 16.5-ton payload capacity that is equipped with a flatrack that is interchangeable between truck and trailer. The combination of truck and trailer provides the combined payload capacity of 33 tons. The flatracks are lifted on and off the truck and trailer by a hydraulic-powered arm mounted on the truck. The hydraulic arm eliminates the need for additional material-handling equipment. The controls for the arm are located inside the cab, allowing the operator to load or unload the truck in less than one minute without leaving the cab of the truck. The trailer can be loaded or unloaded in less than five minutes using the remote-control arm.
M870A4 Semitrailer Lowbed Construction Equipment Transporter, Trailer
M870A4 Semitrailer Lowbed Construction Equipment Transporter (SLCET) is an enabling capability for theater access operations to provide transport of construction equipment and other payloads up to 40 tons. The prime mover for M870A4 SLCET is the M983A4 Heavy Expanded Mobility Tactical Truck Light Equipment Transporter, that in 2008 was approved for Full Materiel Release (FMR) as the prime mover.
The M870A4 SLCET is used by units for horizontal construction projects in support of military, or for other national goals and objectives. The M870A4 SLCET supports construction and maintenance of main supply routes, logistical facilities, bituminous roads, helipads, airfields, landing strips, motor pools and parking areas supporting sustainment operations throughout the full spectrum of operations. The M870A4 SLCET also provides transportation for the Lower Tier Air and Missile Defense Sensor-Large Tactical Power System. The M870A4 SLCET is transportable by C-130, C-17 or larger aircraft, worldwide rail and marine transportable.
The M870A4 SLCET is a commercial item with modifications for military specific requirements. It will replace, in a phased approach, the M870 (A0, A1, A3) Semitrailer legacy fleets that are beyond the Economic Useful Life (EUL) of 30 years. The Army Authorized Objective (AAO) for the M870 fleet is 3,091, which includes the M870A4 SLCET AAO of 2,920. The M870A4 SLCET was approved on 20 December 2022, for Full Materiel Release, and on 21 December 2022, for Full Rate Production. First Unit Equipped is expected 1QFY24.
M917A3 Heavy Dump Truck (HDT)
The M917A3 Heavy Dump Truck (HDT) is a 27.0 ton vehicle based off of a commercial platform. It is procured with an armor solution that is in compliance with the Long Term Armor Strategy (LTAS) v3.6 perimeter ballistic specification and Mine Resistant Ambush Protected (MRAP) CPD v1.1 underbody ballistic specification but can be operated with or without armor. The HDT interfaces with the LEUT Type II Trailer and is the principle prime mover at maximum payload.
The HDT supports construction and maintenance of main supply routes, logistical facilities, helipads, airfields, landing strips, motor pools and parking areas. It also supports construction by loading, transporting and dumping payloads of sand and gravel aggregates, crushed rock, hot paving mixes, earth, clay, rubble, and large boulders at engineering and construction sites under worldwide climatic conditions in a military environment.
