Supacat All Terrain Mobility Platform (ATMP) and Springer

Supacat designed the vehicle but were not able to manufacture in quantity so entered into production sharing contracts and in the early eighties the fifteen ATMP’s were accepted into British Army and Royal Air Force service, all manufactured by Williams Fairey Engineering.

As is common with anything to do with Supacat, the history is complex.

Supacat designed the vehicle but were not able to manufacture in quantity so entered into production sharing contracts and in the early eighties the fifteen ATMP’s were accepted into British Army and Royal Air Force service, all manufactured by Williams Fairey Engineering.

Fairey and Supacat developed the vehicle further and the Mk II was entered into the competition for the British Army’s All-Terrain Mobility Platform (ATMP) requirement for the 5th Airborne Brigade.

Thirty-six Mk II’s entered British Army service in 1988, following trials the year earlier.

In 1995, an agreement was made between Alvis (now BAE Systems) and Supacat in which Supacat would retain design and production rights for civilian markets but Alvis would be responsible for military markets.

In 2005, Supacat regained sole marketing rights.

From the Mk1, through the Mk II, Mark IIa and finally, to the MkIII, the ATMP was incrementally improved. Because of their simplicity, they were not overly expensive either, one of the production contracts for 86 ATMP’s and 84 SLLPT trailers was let for approximately £4 million.

ATMP is a 6×6 design that used low-pressure Terra-Wrangler tires, and with a ground pressure of 0.2 kg/cm, it was highly mobile. Originally powered by a 1.3L Citroen engine, the later versions had a 1.5L VW-Audi engine and automatic transmission. Specifications included a 750-1,000kg payload, increasable to 1,600kg with reduced performance, the maximum loaded weight of 1.6 to 1.8 tonnes, limited amphibious capability, a top speed of 65kph and permanent 6 wheel drive.

The fuel tank has a 50L capacity, increased in later versions.

Because the focus for ATMP was air manoeuvre and logistics, a great deal of thought was put into cargo handling ad weight/dimensional compatibility with in-service aircraft.

Air portability was a key requirement; they can be parachute dropped on  Medium Stressed Platforms (2 per platform), carried by helicopter as a sling or netted load and are internally transportable in a Chinook. A simpler platform could also be used to decrease time to rig and de-rig, this was called the ‘oversill’ scheme.

Given the length of time the ATMP had been in service, all necessary Joint Air Transport Establishment (JATE) clearances were obtained, including various combinations of slinging and airdrop with different aircraft. The Chinook was cleared to carry 2 ATMP’s internally without lowering the roll cage or 4 as a single underslung load.

Merlin internal carriage, Puma sling load and even the Blackhawk were certified.

Multiple stacking options also exist for carriage in larger aircraft such as the C130 and C17.

Compromises were made with the basic design in order to keep weight down and achieve dimensional compatibility, the vehicle had no suspension, thus limiting speed, ground clearance and ride quality.

The second focus area was cargo handling.

Using an integral winch and pair of ramps that were stored in internal compartments parallel to the vehicles long axis, pallets could be simply winched onto the ATMP load bed, secured and the vehicle drove away.

To increase carrying capacity a pair of specially developed trailers were also introduced, the FLPT (Fork Lift Pallet Trailer) and SLLPT (Self Loading Lightweight Pallet Trailer).

Although there are a number of variations, the basic trailer had a hydraulic tipping mechanism and pallet forks. The driver would simply tilt the trailer into the down position, reverse onto the pallet, tilt the trailer back up, and drive away. Maximum payload for the ‘flipit’ trailer was 1,400kg and it could also be converted to carry three stretchers. Demountable corner posts could also be used to form sides for loose loads, with ratchet straps used to secure the load. Conversion took only a few minutes and the posts were carried on the trailer.

Speed, flexibility and simplicity in action.

In addition to clearing landing sites, the ATMP was also used for towing the L118 105mm Light Gun complete with ammunition trailer, total carried and towed payload being in excess of 3,500kg.

Because the basic design was so versatile, it was modified and used for a number of different applications. Several hard or soft cabs, winches, hydraulic jibs, ambulance, recovery, firing posts, firefighting equipment and even a track kit to improve mobility were available. It was also used for unmanned autonomous trials.

GKN make the Air Portable Fuel Containers, currently in service in the Mk5 guise.

The balloon-like, Kevlar-reinforced, containers, can hold up to two tonnes of fuel. When full, the containers are 1.37m in diameter and can be towed, slung load under a variety of helicopters and parachuted from tactical transport aircraft.

Air Portable Fuel Containers Mark 5

The final ATMP version of relevance was the GKN FuelCat.

This was a system designed to support Forward Arming and Refuelling Point (FARP) operation for helicopters and fixed wing aircraft. One vehicle contains a generator, pumping equipment and fuel tank, and the other, a crane and trailer for another fuel container and pipelines. Between the two vehicles, they can carry 4,000 litres of fuel, pump it to multiple aircraft simultaneously and, provide aircraft towing and a gas turbine starting rig.

ATMP FuelCat

Over the years, they have seen service with airborne forces, the Royal Artillery, Royal Air Force and Royal Marines, and with the MoD on range duties.

Deployments included Kosovo, Iraq (both outings) and the early stages of Afghanistan. They were in fact, a direct result of lesson learned during the Falklands Conflict, specifically a lack of all-terrain mobility for light forces, especially their artillery support.

ATMP Deployments

During the 1991 Gulf War, all ATMP’s were converted for the Rapier air defence system towing role.

Following the conflict, twenty ATMP’s were quickly reverted to the standard configuration, a crane added and deployed with Royal Marines to Northern Iraq in support of the Kurdish minorities, OP HAVEN. The C130 stacking pallet and forklift handling proved to be very useful and the low ground pressure reportedly allowed it to be driven into a minefield to recover an injured soldier.

For the second time around in Iraq, ATMP’s that were disposed of to the civilian market were hastily re-purchased and deployed to theatre.

No, honestly.

It is hard not to be enthusiastic about the ATMP, mature, flexible, adaptable, strategically and tactically deployable, and extremely capable. Unlike the Esarco, Multidrive FCV and Stonefield, it entered service and stayed there for some years, and saw action in the Balkans, Iraq and Afghanistan.

But as we know, the British Army can be fickle when it comes to its vehicles and has demonstrated on several occasions, poor capability husbandry.

In Afghanistan, ATMP’s were used to support C-IED efforts, Apache Attack Helicopter refuelling points and in their traditional logistics role but due to years of neglect, a lack of investment in sufficient spares holdings and questions over continued support for a non-Euro compliant engine, they were withdrawn in 2010.

Reliability in the hot weather of Afghanistan was poor, availability of 50% of the deployed fleet on any given day was considered to be good. Cost of spares was proving to be high and taking up valuable space on the air-bridge. An environment mitigation package was considered before withdrawing the vehicles but it was assessed as being equivalent to a complete redesign and therefore, a new acquisition. Supacat informed the MoD that given their workload at the time, would be unable to deliver such a redesigned vehicle for two years.

The MoD then considered further options for the Land Forces Load carrying Platform capability and it was judged that a quad bike and trailer did not have the payload to fulfil the role. A number of manufacturers were asked to ‘express an interest’ including Roush (Balter 2), Development Engineering and Enterprise Limited (WVL-C6-AS), Enhanced Protection Systems UK Limited (Tomcar), Supacat Limited (ATMP 2), John Deere, Yamaha Corporation, Honda Motor Company Limited and JC Bamford Excavators Limited

Of these Yamaha, Honda and JC Bamford Excavators declined the MoD’s offer.

In April 2009, Enhanced Protection System was awarded the contract for 78 vehicles at a total cost of £3 million although other sources have that figure at £7million.

A Tomcar magazine article stated;

The company’s Business Development Director, John Stoddart, who had just returned from a specialist training area in the Southwest where he had been involved in a driver instructor programme. As a former soldier with 35 years under his belt, first as an infantryman and then commissioned REME, who served out the closing years of his armed forces career in Defence Procurement, there can be few better qualified than Stoddart to carry out this urgent operational requirement through from drawing board to frontline deployment

In what was an interesting turn of phrase, Dr Andrew Tyler (Chief Operating Officer for the MoD’s Defence Equipment & Support) stated;

The Springer dune buggy will be an added capability for the troops

The article went on to state;

EPS, which is primarily known for its supply of ballistic protection to the UK MoD but is also a key supplier in the UAV scene had doubled its workforce to cope and subcontracted out some of the work. In its current configuration Springer is fitted with a 1400cc Lombardini diesel engine although larger options are available.

Taking a quote from the MoD’s website

Lack of armour is a benefit. Armour would be paid for with impaired versatility. In any case, Springer’s main purpose is to carry casualties and cargo between relatively safe helipads and base facilities.

Driver training was established at Leconfield and in Germany.

Springer ATV 1

The delivery of 29 Springer vehicles into Afghanistan started in July 2009 and ended with the last batch, consisting of 2 Springer vehicles, received in Afghanistan in July 2010.  Transportation of the Springer vehicles, to and from Afghanistan, was via land and sea. The balance of the fleet was used for training and development purposes.

In September 2009, the Sun reported problems with the Springer fleet that had emerged during initial driver training.

And to add to Mr Brown’s woes, fears have been raised over a £7million fleet of off-road Army vehicles set to be flown to Afghanistan next month. A military source said that despite being passed fit for use, there had been “real problems” with steering during testing of the Springer vehicle. The concern over the 40mph Springer buggies came during tests at the Defence School of Transport at Leconfield, Yorks. Seventy of the two-seater buggies have been bought to help transport casualties between helipads and bases.

One tester of the Springer said the vehicle needed bigger rear tyres and more power. And a senior military source told The Sun the teething problems were worrying.

He said: “We have a real problem with the Springer. This is meant to be a tough go-anywhere vehicle capable of high speed over rugged ground. To have steering columns damaged by a few bad bumps in Yorkshire is of some considerable concern.”

The MoD denied any problems, of course with an MoD spokesman telling the newspaper;

There have been no reports of problems with the vehicle. Springer has successfully passed its trials with the Army, has been declared fit for purpose and is going into service

Nothing to see here; move along, the deployment continued.

Jane’s also described a Springer 2 revision, retrofitted to existing vehicles as a result of operational experience but these would not solve the fundamental problems.

[/tab] [tab title=”Springer and Quad”] merlin-on-operations-in-helmand
[/tab] [/tabs]

The Springer was removed from service in March 2011, recovered from Afghanistan and declared out of service by September 2011.

All 78 vehicles were sold to civilian users for about £7-10k each and for the rest of operations in Afghanistan, quads and trailers were used, despite the MoD judging they were unsuitable, the very reason the Springer acquisition was initiated.

A rare UOR failure

After the Springer UOR was introduced for Afghanistan and then withdrawn, Supacat developed the MkIII ATMP.

At the Land Forces 2014 exhibition in Australia, Supacat showed off their concept for a new and improved Supacat, the Mk IV.


Commenting on the updated design, Michael Halloran, MD of Supacat Pty Ltd, the Australian subsidiary of Supacat, said:

When we looked around the market, we found that there is nothing that combines the payload, mobility and robustness of the ATMP, so in developing this concept vehicle we decided to look at maintaining the fundamental strengths of the platform while updating the human interface and the automotive and communication systems.

All Terrain Vehicles have even developed an improved amphibious capability for it.

ATMP Amphibious

That isn’t the end of the Supacat ATMP story for the British Armed forces, although, at this point, it seems unlikely to re-enter (again) service with the British Army.

At the Royal Navy’s Unmanned Warrior 16 exercise, an ATMP MkIII was used to support the QinetiQ team.

Subsequently, the MoD issued a tender requirement for a range of support services for the maritime autonomous trials team (MASTT).

Short description of the contract or purchase(s)

Support equipment. The Mine Counter Measures and Hydrographic (MHC) Project Team is conducting independent trials in conjunction with the Royal Navy Maritime Autonomous Trials Team (MASTT) of unmanned underwater vehicles for future mine countermeasures operations. The equipment used varies from land vehicles to unmanned underwater vehicles. To maintain this equipment MHC is considering a maintenance support package. Some of the equipment requires specialist support and may necessitate contractor engagement with the Original Equipment Manufacturer (OEM).

The Authority envisages that the scope of the requirement will include Level 2 & 3 maintenance, repairs, upgrades, technical support, spares support, Post Design Services (PDS), operator and level 1maintainer training and safety case support. In addition, it is envisaged that the equipment detailed below will be stored at the Authority’s premises at Portsmouth Naval Base.

Equipment to be maintained and supported
— Supacat SUV 600 is a Landrover Discovery 4 with the addition of a 3rd axle and uprated braking components an interchangeable rear body and fifth wheel coupling has also been fitted.
— Supacat Personnel, Accommodation and Transportation (PAT) trailer. The PAT trailer contains living accommodation and space to transport other MASTT equipment.
Supacat 6X6 MK3 All Terrain Multi Purpose vehicle fitted with a Pathfinder hydraulic crane
— A V8 M500 Ocean Modules Remote Operated vehicle complete with Hydrolek HLK 43000 Manipulator arm, winch and RNMB HAZARD deck launch plate
— ROV/Manipulator arm Launch and Recovery System fitted to RNMB HAZARD
— Hydroid Inc Remus 600 transportation trailer
— Hydroid Inc Remus 600 Launch and recovery system including stowage frame
— Oceanserver Iver 3 UUV
— SeeByte Ltd autonomous behaviours software (fitted to Remus 100 and Iver 3 UUV)
— QinetiQ Ltd Portable C2 Operating Centre (ACER)
— ATLAS Elektronik UK Ltd Future Exercise and Ranging Mine
— High Precision Acoustic Positioning System (HiPAP)
— Portable Generators — 3 (2 x 5.5Kw & 1 x 1.6Kw outp.

Emphasis added, and I think they meant to say Palfinger hydraulic crane not Pathfinder hydraulic crane.

So there you go, ATMP has entered, left and been reintroduced to service with the British Army a number of times and seems is now back in service, but with the Royal Navy, albeit on a supplier support contract basis.

The vehicle concept remains sound, the vehicle itself is sound, especially the MkIV.

It is a shame that UK airmobile forces have no mobility platform when the ATMP is manifestly suitable and would be relatively easy to re-introduce, given all required aircraft and mobility clearances already exist.

In 2018, Supacat announced it would collaborate with the University of Exeter on a modernisation programme that would both addres obsolescence issues and also develop a hybrid drivetrain and automisation.

Development of the H-ATMP continued and an optionally unmanned variant was shown at DSEi 2019. H-ATMP features electric motors made by Dana TM4 and the vehicle can also export power to a variety of off-board equipment. Further details here.

With the Future All Terrain Vehicle (FATV) programme the Army may soon acquire another ATMP-type platform. This is a new requirement to support dismounted infantry by reducing the weight burden. It was recently described to me as 21st Century Bren Gun Carrier. Sounds interesting and if it can live-up to the Universal Carrier’s solid gold reputation, it should be great little asset. Not much is known at this stage, but we should learn more later this year assuming it doesn’t die.

A wheeled, AMTP style, amphibious capable, Universal Carrier concept, with a reinforced (pallet-sized) bed and optional jack legs for using as a solid platform would likely be incredibly useful.

September 11, 2020 2:24 am

Monty – I could be wrong but I think you have your wires crossed. The FATV is the replacement for the BV206, not a requirement for supporting dismounted infantry.

The experiments around supporting dismounted infantry has seen the DSTL buy Milrem THeMIS, Rheinmetall Mission Master and HORIBA MIRA Titan UGV’sfor testing. Also unfortunately I am not sure the unmanned ATMP Is included in that testing.

Just like to add a little further information on the FuelCat ATMP variant. The attached photos show the world’s first Supersonic Landspeed Record car, Thrust SSC: The FuelCat proved to be extremely versatile in not only refueling the Thrust Car at the end of each run but also towed the Car out onto the desert tracks, provided gas turbine engine start support, electrical power back-up and vehicle recovery
