RMMV HX range of tactical trucks
The HX family are a range of purpose-designed tactical military trucks manufactured by Rheinmetall MAN Military Vehicles (RMMV). The HX range was disclosed in 2003, and the first order was placed in 2004. The HX range replaced the earlier FX and LX ranges in production. The HX2 range, which currently complements the original HX range, was announced in 2012. The first HX2 range trucks were delivered in April 2016. The HX and HX2 ranges originally complemented the SX range, but as of 2019 they had replaced the SX range as the type was no longer produced. The HX3 range was announced in May 2021, with series production scheduled for 2024.

RMMV (then MAN) confirmed it was developing the HX range at Defence Vehicles Dynamics (DVD) 2003 and a developmental example shown later in the year at DSEi 2003. The earlier LX range was superseded by the HX range in 2004. The FX range was superseded in 2005.
The first order for the HX range came from the British Army which announced in October 2004 that it had selected the MAN ERF UK Ltd proposal to meet the Support Vehicle requirement. The contract was awarded in March 2005.
On 6 May 2021 Rheinmetall unveiled the HX3.
The HX/HX2 ranges of trucks combine militarised commercial driveline and chassis with the latest version of a modular military-specific cab. The HX/HX2 ranges are based on chassis and driveline components of MAN's commercial TG WorldWide heavy truck range which was first introduced in 2000. The HX2 range use a dedicated chassis.
MAN water-cooled diesel engines of various power outputs and emissions compliance are used across the range, these including the D0836, D2066, D2676 and D2868. The engine remains positioned conventionally (longitudinally between the chassis rails), however, the cooling pack is located transversally at the rear of the cab. This location offers protection from damage and blockage of the radiator with mud etc. when operating off-road. It also allows for a larger volume radiator to be used, which enhances hot-climate operating capability.
A ZF AS-Tronic automated constant mesh gearbox (branded TipMatic in MAN’s commercial product line up) with 12 forward and two reverse gears is standard fit, this coupled to a MAN two-speed transfer case. A powershift-type fully automatic transmission is an option.
Drive axles are MAN single tyre hub-reduction, and with the exception of the heavier tractor units which are full-time all-wheel drive for traction and torque distribution reasons, all models have selectable front axle(s) drive. All axles have cross-axle differential locks and there are longitudinal differential locks in rear (and front on 8×8 and 10×10 chassis) axle combinations and the transfer case. Axle weight ratings are 9000 kg or 11,000 kg for front axles, and 10,000 kg for rear axles with single wheels/tyres.
Front steer-drive axles (including the 2nd axle on 8×8/10×10 chassis) are sprung by a combination of parabolic leaf springs with progressively acting rubber assistors and hydraulic telescopic shock absorbers. Rear axles are sprung by inverted multi-leaf trapezoidal springs with radius rod and an anti-roll bar. A conventional rear bogie set-up is employed for 6×6 and 8×8 chassis. The HX45M 10×10 features hydropneumatic suspension for the rear three axles.
The standard 14.00 R 20 tyres may be replaced by 395/85 R 20, 525/65 R 20 or 16.00 R 20 tyres if required. A central tire inflation system (CTIS) or semi-automatic tire inflation system and run-flat inserts are options.
With the exception of the modular military cab, the location of the cooling pack and a small number of military specific ancillary items and modifications, for cost efficiency reasons RMMV has strived for maximum commonality with the TG commercial product.
The HX3 was unveiled on 6 May 2021. Like it predecessors, the HX3 is designed for purpose and is classed a military-off-the -shelf (MOTS) product. The HX3 will be available in 4x4, 6x6, 8x8, and 10x10 configurations, with the 8x8 and 10x10 options available with active rear suspension and rear-axle steer options. A fully Automated Load Handling System (ALHS) and Universal Torsion-Resistant Subframe (UTRS) will further enhance capability in the traditional logistics role, while the Artillery Truck Interface (ATI) could see the 10x10 utilised in future as the standard basis for various artillery solutions or similar systems.
The HX3 remains based around militarised MAN commercial components, with new safety features carried across from the commercial product including Emergency Brake Assist (EBA), Adaptive Cruise Control (ACC) and Lane Departure Warning (LDW), all of these disconnectable for tactical applications. EURO 6 engines are standard, these compatible with military grade fuels following limited modifications. For consistent use on lower grade fuels (up to 5000 ppm sulfur), a EURO 2 engine option is an option. Autonomous driving options will also be available.
The flat-paneled military cab of the HX/HX2 models has been redesigned for the HX3. A new single piece flat mine blast protecting floor is used, this allowing for standard commercial seats to be used for the crew, these with five-point harnesses if required. Air-conditioning is now relocated from the roof to within the new dashboard assembly, the compressed air cylinders now moved from the chassis frame rails to the roof. All stowage boxes are watertight, the HX3 capable of fording in up to 1.5 m of salt water. Other off-road performance criteria includes a vertical step of 590 mm and an approach angle of 40 degrees. The HX3-specific chassis frame allows for up to 400 mm of torsional twist.
To meet increasing demands for crew protection on deployed operations the HX range was designed from the outset with protection options in mind. In standard configuration a blast-proof vertical split-windscreen is fitted, and a riot protection kit is available for the cab. For more significant threats an appliqué protection kit, for which vehicles are prepared to accept at the production stage, have been developed in conjunction with Ressenig of Austria and Rheinmetall of Germany. Known as the Modular Armour Cabin (MAC), in basic specification these kits weigh around 1500 kg. The cab hard-top remains removable for air-transport if required.
A swap-cab armouring solution known as the Integrated Armour Cabin (IAC) is also available. The IAC was originally developed in conjunction with Krauss-Maffei Wegmann (KMW) for the SX range of trucks, this suited to models with twin front axles only. A Rheinmetall-developed IAC option is now available, this suitable for all HX range trucks, depending on front axle rating and protection levels. Australia, Norway, and Sweden are receiving trucks with this cab which is manufactured at a purpose-constructed facility recently opened at Rheinmetall's facility in Unterlüß, Germany.
World record attempt - ChileEdit
On 6 November 2017 Rheinmetall announced the company was a main sponsor for high-altitude record-breaking attempt that had commenced that day. Using two HX range trucks (a 340 hp 4×4 HX40M and a 440 hp 6×6 HX58) the expedition aimed to reach the highest point on earth accessible to motor vehicles – the 6890 m-tall Ojos del Salado, the world’s highest active volcano, located on the border of Chile and Argentina. In order to set a new world record the vehicles would have to reach an altitude of at least 6,690 metres above sea level. On December 19 it was announced the altitude record attempt had been called off at a height of 6,150 m for a combination of factors including an insurmountable rock barrier and adverse weather conditions. The team had, however, built two refuge huts during their ascent, the highest of these built at 6,100 m, a record.
- Australia - 2536 HX models ordered in July 2013 as the Phase 3B part of project Land 121. Australia was the first customer to receive HX2 variants. First vehicle handover occurred on 7 April 2016, when 6 HX77 (8×8) and 6 HX40M (4×4) were handed over. A further 1044 ordered in July 2018 as Land 121 Phase 5B, an extension of Phase 3B. Initial Operating Capability for Phase 3B trucks declared in February 2020. As of April 2021 around 800 trucks were left to build and deliver, with final deliveries expected during 2023.
- Austria - Just over 50 HX trucks. Totals include 20 HX77 8×8 configured with a load handling system and armoured cab in 2006, plus 20 HX42M 6×6 and four HX81 HETs ordered around 2017/2018, and five HX44M 8×8 (2 x TEP 90; 3 x heavy recovery) on order as of 2019.
- Colombia - Small quantity (possibly 2); use unknown.
- Denmark - Just over 200 HX trucks to all branches of the armed forces from late 2006. Totals include 113 HX77 8×8 fitted with a load handling system, 83 HX77 8×8 in conventional cargo/tanker truck configurations, about five HX58 6×6 in tractor unit configuration to the Danish Air Force, and four HX60 4×4 in container/cargo configuration.
- Germany - On 6 July 2017 it was announced that RMMV had entered a seven-year framework agreement with the Bundeswehr to supply up to 2271 HX2 trucks worth around €900 million. An initial batch of 558 trucks worth around €240 million (including training support) were ordered for delivery between 2018 and 2021. The first 20 trucks were handed over to the Bundeswehr in November 2018. A second batch of trucks were ordered in June 2019, the order valued at €420 million and covering 252 trucks (161 5-tonne HX42M (6×6) and 91 15-tonne HX45M (8×8) and including specialist tools and training support. A further 60 trucks were ordered in November 2019, and in December 2019 a further 1000 additional trucks were ordered (675 5-tonne HX42M (6×6) and 325 15-tonne HX45M (8×8)) for €382 million. Under the Bundeswehr’s Unprotected Transport Vehicle (UTF) programme, these HX2 trucks will replace the old KAT I generation of trucks made by MAN, some of which have been in service for forty years. The Germany Army also operates a fleet of RMMV HX81 8×8 heavy equipment transporters coupled to DOLL semi-trailers. By July 2015 the Bundeswehr had ordered 21 HX81 with armoured cabs in three batches from 2006 (2 + 12 + 7). In June 2018 a seven year framework-type award to RMMV was made for up to 137 HX81 (now known as Elefant 2 or SaZgM 70t mil). Total contract value could reach EUR122 million and an initial 32 vehicles valued at about EUR32 million were ordered, these vehicles featuring the same unprotected driver’s cab as the UTF family of vehicles. In December 2020 Rheinmetall announced an award for a further 24 vehicles to be delivered during 2021, with 24 more in 2022. Value of this award was given as EUR41 million. In June 2020 Rheinmetall announced a further Bundeswehr order for HX range trucks. It was disclosed that Germany's Federal Office for Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) had entered into a framework contract with RMMV for delivery of up to 4,000 trucks fitted with a hooklift system, many of which will feature armoured driver’s cabs. Running from 2021 to 2027 for Rheinmetall the framework contract represents around €2 billion in total sales volume. An initial tranche of 540 vehicles worth around €348 million have been ordered, and of these 230 will be protected. Delivery starts 2021
