The M1070 is a heavy-duty military transport truck manufactured by the Oshkosh Corporation of Wisconsin in the United States. The 8x8 wheeled series began service in 1992 and has been adopted beyond the United States by the forces of Egypt, Iraq, Israel, Taiwan, the United Kingdom, and others (see list below for full extent). The powerful hauler is used to transport combat tanks, Armored Fighting Vehicles (AFVs), and other battlefield systems from Point A to Point B and also makes for an excellent towing platform, able to clear damaged/fallen obstacles from roadways due to its inherent power.
The truck was drawn up by Oshkosh engineers specifically for the U.S. Army as a dedicated transport for the M1 "Abrams" Main Battle Tank (MBT). Three primary variants have since emerged - the M1070A0, M1070A1, and the M1300 (the trio detailed below).
The arrangement of the truck is largely conventional with a pseudo cab-over-engine configuration. The driver sits at front-left with the engine ahead and under the crew compartment. The sloping hood allows for some vision over the rather tall nose and the overall height of the vehicle restricts access to some locations. An 8x8 wheeled configuration is used in which a forward axle is supported by three rear axles and large, rubber-tired road wheels provide good traction on paved surfaces and dirt roads. The front axle is steerable (power-assisted) and a Central Tire Inflation System (CTIS) is standard for on-the-fly tire pressure settings depending on terrain/environment. The spacious cab seats the driver as well as five others.
Despite its dimensions and base weight, these oversized trucks can be air-transportable in the belly of the larger U.S Air Force haulers such as the C-17 "Globemaster III" and C-5 "Galaxy" strategic airlifters, allowing it to be deployed anywhere in the world.
Dimensions include a running length of 30 feet, a width of 8.5 feet, and a height of 13 feet. The drivetrain allows for a maximum, unladen road speed of about 45 miles-per-hour with an operational range out to 450 miles.
Armor protection is thought to be light-to-medium but an add-on kits enhance survivability to an extent - critical for when operating in contested environments.
The M1070A0 entered service with the Detroit Diesel 8V-92TA diesel engine of 500 horsepower mated to an Allison CLT-654 five-speed automatic transmission system. By the time of the modified M1070A1, the powerpack had switched to the Caterpillar C-18 6-cylinder turbocharged diesel unit of 700 horsepower with an Allison 4800SP seven-speed transmission system. The truck is typically joined to the wheeled/five-axle M1000 series trailer component.
The M1300 is a U.S. Army variant reworked to adhere to European Union (EU) restrictions - mainly related to weight.
The British Army uses the M1070F and began operation of the series in 2001. The F-model is based in a modified M1070E1 which was not initially taken on by the service for reasons, the F-model better fulfilling the Army need. This model is powered by the Caterpillar C-18 diesel unit of 700 horsepower and mated to an Allison HD 4076P transmission system. The trucks have been featured in Afghanistan as well as NATO commitments/exercises.
