Supacat's All-Terrain Mobility Platform (ATMP) is a versatile light vehicle used by airborne and airborne battalions. Developed in the 1980s, the ATMP 6x6 was Supacat's first product.
The six-wheeled ATMP all-terrain vehicle, due to its very low ground pressure and amphibious capabilities, has a unique cross-country ability, in particular, it is able to overcome rough sandy terrain and water obstacles. ATMP is capable of carrying one standard NATO pallet, ammunition, anti-tank mines and other bulky or heavy loads.
The 6x6 Supacat ATMPС all-terrain vehicle has been in the service of the British armed forces since the mid-80s, and the 1800 kg version of the ATMP, powered by a VW-Audi engine, can now be found not only in the Airborne Forces, but also in the Royal Artillery and Royal Marines …
The ATMP is capable of carrying a substantial payload for a vehicle of this size, which, combined with its all-terrain capability, has ensured the vehicle is in good demand for years to come. Perfectly proven in various military operations and military conflicts, the ATMP can be transported both externally and inside various air platforms, which ensures its operational availability for airborne forces and rapid reaction forces. There were reports in the press that the British special services used ATMP 6x6 all-terrain vehicles in the reconnaissance phase of the operation against one of the prominent leaders of the Taliban in Afghanistan.
The ATMP has a permanent 6-wheel drive and is capable of transporting 2 crew members and up to 8 troops.
ATMP can be configured to perform various tasks:
- troop transportation
-
provision of supplies
- mobile fire support base
-
pallet forklift and trailer
- aviation fuel carrier
-
evacuating the wounded
- recovery vehicle
-
preparation of landing areas
Image The history of the creation of the ATMP, which entered service in 1988, is as complex as the history of everything that Supacat has created.
The company Supacat, which developed the ATMP, was unable to produce them in sufficient quantities. In this regard, the company had to share a contract with other manufacturers (the same situation has developed with the Jackal all-terrain vehicle). Thus, it turned out that in the early eighties, the ATMP all-terrain vehicle manufactured by Fairey Engineering was adopted by the British army.
Image In 1995, an agreement was concluded between Alvis (now BAE) and Supacat, according to which Supacat retained the rights to design and manufacture civilian versions of the all-terrain vehicle, and Alvis was responsible for military markets. In 2005 Supacat regained exclusive marketing rights.
In 1996, the UK Department of Defense acquired 86 more ATMPs and 84 trailers for a total of approximately £ 4 million.
Image The ATMP Mark 3 is capable of carrying a payload of 1000 kg (it can be increased to 1600 kg due to reduced cross-country ability), weighs from 1.6 to 1.8 tons, has limited amphibious capabilities, has a top speed of 65 km / h and has permanent all-wheel drive. Despite the open design, the all-terrain vehicle can be equipped with a number of rigid or soft cabins, a winch and even a tracked kit to further increase the cross-country ability.
In addition to the existing winch, a number of special trailers FLPT (Fork Lift Pallet Trailer) and SLLPT (Self Loading Lightweight Pallet Trailer) were developed to ensure self-loading and unloading of pallets and cargoes, in addition to the existing winch.

Image There are several options, but the main trailer is equipped with an electro-hydraulic tipper and fork. The driver simply tilts the trailer down, points it towards the pallet, tilts the trailer back and drives off. The whole process is very fast, simple and can be done from the comfort of the ATV. FLPT trailers have a maximum payload of 1400 kg and can be converted to carry three stretchers. The trailer is equipped with removable corner posts with lashing straps. These attachments are also used to transport bulk cargo such as boxes or used pallet parts. Deploying the kit takes only a few minutes.

Image An aircraft crane was also developed that allows ATMP to independently load up to 1 ton from a two meter distance. Thanks to its high thrust, the ATMP is also designed to tow a 105mm cannon and an ammunition trailer. Thus, the total transportable and trailed payload exceeds 3500 kg. There are also airborne portable fuel containers.
One of the key requirements of ATMP was airborne start-up, so the all-terrain vehicle can be dropped by parachute, transported on the external suspension of a helicopter on slings or in a net or in the internal compartment of Chinook. During its long service, ATMP has passed all the necessary qualifications, including various combinations of slinging and airborne assault from various aircraft. The Chinook helicopter is allowed to simultaneously carry 2 ATMPs in the internal compartment or 4 on the external sling. There are several ATMP stowage options for transporting large aircraft.
To provide mobile fire support, the ATMP is equipped with a large-caliber machine gun or the Milan anti-tank guided missile system.
The estimated cost of the base ATMP model is 8.5-9.5 thousand pounds.
Image Rover configuration
The ATMP has a permanent drive (6x6) with front four steering wheels (two axles) steered by a motorcycle-style steering wheel. The steering wheel also controls the steering disc brakes, which act independently of each other on both sides of the ATV and provide the ATV to turn by skidding. The ATMP is driven by a diesel engine and controlled via a torque converter. ATMP is equipped with an automatic transmission with three forward and one reverse speeds and one differential. A dual output shaft transmits torque to two transfer cases with integrated internal disc brakes. The center shaft is driven directly from the transfer case. The disc brake foot pedal acts on all wheels at once. Torque is transmitted to the front and rear wheels via a heavy duty twin chain in one-inch increments. The ATMP is built around a rectangular steel frame that forms the entire shape of the all-terrain vehicle and on which all components and attachments are mounted. The ATMP body is made of aluminum, which allows the ATM to float and protects most of the mechanical components. The bottom is covered with a 5 mm aluminum plate.
