JAIS 4×4 is a mine-resistant ambush protected (MRAP) vehicle being manufactured by NIMR Automotive, a part of EDGE Group based in the UAE. It offers an optimal combination of firepower, survivability, and tactical mobility to support conventional, modern, and asymmetric combat operations.

NIMR signed a teaming agreement with Saudi Arabian Military Industries (SAMI) at the International Defence Exhibition and Conference (IDEX) 2021 to explore new opportunities for JAIS 4×4 vehicle in Saudi Arabia.

SAMI entered a manufacturing license agreement with NIMR at the World Defence Show in March 2022, for the production of JAIS 4×4 in Saudi Arabia.

JAIS 4×4 design and features

The JAIS 4×4 MRAP is based on the RG35 vehicle developed by South Africa-based Land Systems OMC, a subsidiary of BAE Systems. Its modular design provides cost-effective configurations for reconnaissance, patrol, utility, and special mission roles.

The armoured hull of the vehicle is divided into three main segments with the driver and commander positions and engine at the front and the troops’ section at the rear. The forward hull is fitted with a large wide screen that provides excellent field of view for the driver and commander.

The vehicle can accommodate seven personnel including two crew and five troops. A hydraulic door on either side of the hull and a hydraulically-operated large ramp at the rear enable the entry and exit of the occupants. Each side of the hull has two small bulletproof windows, which offer all-round visibility to the troops inside the vehicle. The vehicle also features roof-mounted hatches.

The JAIS 4×4 vehicle has a length of 5.98m, an overall width of 2.79m and a height of 2.63m. The gross vehicle weight (GVW) of the MRAP vehicle is up to 21,000kg, while its maximum payload capacity is 3,200kg.

The vehicle can be optionally equipped with a three-stage ride height management system, a winterisation kit, a fire suppression system, health, usage, and monitoring system, C4I command and control and situational awareness systems, a self-recovery winch, an electrical power management system, and driver aids.

JAIS 4×4 armament

The JAIS 4×4 armoured vehicle can be installed with roof-mounted one/two-man light and medium-size turrets armed with up to 20mm calibre guns.

The MRAP vehicle can also be mounted with a remotely-controlled weapon station (RCWS) armed with a 7.62mm or a 12.7mm machine gun.

Self-protection

The vehicle offers superior protection in line with the highest international standards. It can protect the occupants from improvised explosive devices (IEDs), land mines, and ballistic threats.

Roof-mounted armament, command and control systems, and mission equipment further enhance crew survivability.

In addition, self-protection levels of the vehicle can be increased with the integration of heat signature management, rocket-propelled grenade (RPG) protection, and nuclear, biological and chemical (NBC) defence systems.

Engine and mobility

The JAIS 4×4 mine-protected vehicle is powered by a Caterpillar engine with a power output of 450hp (336kW). The engine is coupled to a six-speed automatic transmission. The engine and gearbox are positioned on sliding rails to ease maintenance.

The JAIS 4×4 also comes with standard equipment such as a power management system, run-flat tyres, and a central tyre inflation system (CTIS).

The vehicle has a maximum road speed of 105km/h and a maximum cruising range of 700km. It features double-wishbone independent suspension with hydro-pneumatic struts for high mobility in all-terrain conditions, while wheels are fitted with air-actuated disk brakes for better control on different surfaces.

The vehicle can negotiate a gradient of 60% and a vertical step of 600mm. It can cross a trench of 900mm and ford a depth of 900mm.
