Tactical Vehicle M-ATV

Tactical Vehicle M-ATV

The mine-resistant ambush-protected (MRAP), all-terrain vehicle (M-ATV) Assault is a new member of the combat-proven M-ATV family of vehicles produced by Oshkosh Defense to meet the challenging requirements of the armed forces in hostile environments.

The M-ATV was recently displayed at the IDEX Conference 2017 held in Abu Dhabi in February.

The vehicle can be deployed in special reconnaissance and target acquisition, military intelligence, conventional and unconventional warfare, and command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) missions.

M-ATV Assault design and features

The M-ATV Assault vehicle is built based on the medium tactical vehicle replacement (MTVR) chassis. It features an armoured capsule made of bolt-on armour materials. Its hull offers reduced visual, thermal and electromagnetic signatures. The extended wheelbase results in large interior space.

The single compartment crew capsule houses modular seating to accommodate up to 11 crew members on two forward-facing, three rear-facing seats and two rows of three inward-facing, fixed-configuration foldable seats.

The centre seat in the second row can be converted into a gunner stand. The seating is designed to ensure easy ingress and egress, while the rear wall and roof hatches enable rapid deployment of troops on the battlefield.

Observation features

The M-ATV is also installed with driver’s vision enhancer and enhanced situational awareness (ESA) system from DRS Technologies.

The vision enhancer offers wider fields of view and avoids blind spots in order to enable safe navigation through dust, sand, smoke, light fog, and darkness.

The ESA system integrates a driver’s vision enhancer, two DVE UltraLite thermal cameras and a DVE UltraWide vision system.

The modular C4ISR suite aboard the vessel incorporates situational awareness systems, improvised explosive device (IED) defeat systems and jammers to enhance the operational effectiveness during missions.

Design

The M-ATV combines a Plasan designed armored hull developed for the Northrop Grumman/Oshkosh JLTV Technology Development (TD) phase proposal with some elements of the Medium Tactical Vehicle Replacement (MTVR) chassis and Oshkosh’s TAK-4 suspension system. TAK-4 suspension is coil sprung and fully independent, and offers 16 inches of wheel travel.

For survivability, and in addition to the V-shaped hull which is optimized for IED protection, other aids include the ability to take a 7.62 mm round to the engine oil/coolant/hydraulic system and continue to drive for at least one kilometer. The engine compartment is also protected with the Stat-X engine fire suppression system. A central tire inflation system (CTIS) and run-flat inserts allow the M-ATV to travel at least 30 miles at 30 mph even if two tires lose pressure. The M-ATV also features a traction control system and anti-lock brakes.

Armament is roof-mounted and can be either manually or remotely operated. Manual options include a M240 machine gun, a Mk 19 grenade launcher, an M2 Browning machine gun, a MILAN anti-tank guided missile, or a BGM-71 TOW anti-tank guided missile launcher. Remote option is usually the CROWS (Common Remotely Operated Weapon Station), however as previously mentioned, Oshkosh has also fitted for demonstration purposes the R400S-Mk2, a 3-axis stabilized remote weapon station.

Other M-ATV features include a HVAC system and power outlets for charging portable electronic devices. The M-ATV is also unique among MRAP-type designs in that it uses suicide-type rear doors.

Armament and self-protection

The M-ATV Assault is mounted with a Moog reconfigurable integrated-weapons platform (RIwP), which is armed with an Orbital ATK M230LF 30mm lightweight automatic chain gun, an M249 machine gun, a Javelin missile, and a long-range target acquisition sensor suite.

The dual-axis stabilised system is guided by a single or dual-axis independently stabilised sight system to increase the first round hit probability on the move. The universal missile platform also allows for firing of a wide range of existing ground platform missiles of the US Army.

The RIwP enables the gunner and commander to switch between direct fire, missile, sight and non-lethal configurations to counter asymmetric threats in the battlefield. It also enhances the situational awareness with a gunner’s hatch and ensures the weapon reload under armour protection.

The vehicle features an Advanced Core1080™ crew protection system, which offers integrated blast protection. The energy-absorbing floor and seats, as well as the wheel zone, blast deflectors to enhance occupant safety.

The vehicle can be optionally fitted with Oshkosh gunner protection kit (GPK). It is also equipped with automatic fire-extinguishing systems for increased protection.

Engine and mobility

The M-ATV Assault is powered by a Caterpillar C7, 7.2L engine with a rated power output of 276kW. The engine is coupled to an Allison 3500 SP six-speed automatic transmission. The drivetrain includes a two-speed, full-time four-wheel drive with locking differential.

The vehicle integrates a TAK-4® independent suspension system for best-in-class mobility on rugged terrains. The suspension system includes standard coil, high-pressure gas (HPG) and hydro-pneumatic springs.

The central tyre inflation system (CTIS) further enhances the mobility across different terrains. The two-channel system comes with four terrain settings with integrated driveline lock-up control. The vehicle has a curb weight of 16,700kg and can carry a maximum payload of 2,000kg.
