Name: MRAV-5
Purpose: Multi-role Mechanized Fighting PlatformThe MRAV-5 is an eight-wheeled MRAV designed as a joint-venture between Voss Defence Inc. and LG Defense Systems of Tergnitz Inc. MRAV-5 easily dwarves most contemporary vehicles with its size. At 34 ton combat weight, it is also about 10 tons heavier than many other contemporary vehicles within the same role. It is designed to carry out a variety of utility missions with maximum flexibility; this is achieved via several different
"mission modules" specialized for various tasks which are available separately from the vehicle. The base vehicle is independent of the modules, and modules can be interchanged within an hour. Each module incorporates a primary safety cell with a triple floor. MRAV-5 is built with a high degree of standardization, and designed to be maintained easily and efficiently.
Current Mission Modules: * [MRAV-5A] - Armored Personnel Carrier
* [MRAV-5B] - Command Post
* [MRAV-5C] - Infantry Fighting Vehicle
* [MRAV-5D] - 120mm mortar
* [MRAV-5E] - Medical Evacuation Vehicle
* [MRAV-5F] - Integrated Anti-Aircraft
* [MRAV-56] - Engineering Service Vehicle
* [MRAV-5H] - Logistics
The basic vehicle shell is composed of hard steel, and "modular armor" is sandwiched between it and the vehicle cell. The three elements are held together by fastening bolts. The modular armor, is a specialized ceramic mix, but is designed to be easily upgradable by future developments. The hull provides protection against top attack bomblets and AP mines, including "hanging" seats to improve crew protection from explosions below the vehicle. Modules are changeable in about 45 minutes.
The basic combat vehicle is equipped with a remotely operated turret housing the 2A38M-short 40 mm caseless cannon firing up to 350 rounds per minute. This 40mm caseless round has the same performance as 40mm Bofors and the 50mm Supershot in a design that is just 233mm long. Its 1 kg high explosive round is three times the size of a 30mm projectile so it will penetrate the thick walls which currently defeat the smaller round, or can be detonated in mid-air to attack troops behind cover. Its armor-piercing round can penetrate more than 150mm of armor plate.
There are also versions of the vehicle equipped with a 120mm autoloading mortar system, a 105mm cannon and an anti-aircraft version. The anti-aircraft version is perhaps the most unique vehicle of its type. It is a single 2A38M-short 40mm caseless cannon supported by a Six tube Spike S missile launcher. The Spike S is basically a ground launched version of the Spike AAMRAM. In its anti-aircraft role the MRAV-5 can fire its cannons in several modes of operation, radar, passive radar, passive vortex and optical, in radar mode the target tracking is fully automatic, with the guns aimed using data from the radar. Passive radar tracking allows the vehicle to home in on the radar emissons of an attacking aircraft or missile, while passive vortex utilizes sensors that monitor aerial disturbances produced by helicopter rotors and soundwaves to engage targets out to 5km, In optical mode the gunner tracks the target through the stabilized sight, with the radar or passive radar providing range data.
The mortar vehicle features a remotely controlled automated, single-tube, 120-mm smoothbore turreted mortar. The vehicle features some highly advanced systems including automated ammunition storage and handling, breech-loading, in-bore air regulation system (IBARS) and automated mortar cooling system (AMCS) subsystems. The unique and patented accelera system allows firing of the mortar at low angels to increase effectiveness while integrating recoil control and layering systems to provide a highly accurate platform. The system uses a number of high tech rounds including the laser guided munitions.
The MRAV-5 utilizes state of the art electronics, sensors and counter measures. Both the gunner and Commander have independant FLIR and an electro-optical/TV imaging systems, and direct-view optics with the eye-safe laser rangefinder.The fire control software (FCSW) combines laser range, environmental readings, ammunition type, and turret control inputs to automatically elevate the gun for range and to automatically generate a kinematic lead solution if a target is moving. If the weapon misses its intuitive targeting subsystem automatically fires on the two most likely enemy positions scoring kills 87% and 99% of the time respectively. NBC protection systems are standard equipment.
When needed the vehicle can be fitted with Contact Reactive Armor. The Contact Reactive Armor ERA consisting of an explosive sandwiched between two metal plates adds to the vehicles protection. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. This will force an incoming KE-penetrator or shaped charge jet to cut through more armour than the thickness of the plating itself, since "new" plating is constantly fed into the penetrating body. ERA armor covers the front, side and top of the vehicle.
The Optronic counter measures system is designed to disrupt laser target designation and rangefinders of incoming ATGM. Optronic includes a laser warning package that warns the tank crew when it is being lased and an electro-optical jammer. Plus there is a grenade discharging system which produces an aerosol screen and a computerized control system to coordinate the vehicles defense and its Chainmail active protection system.
To increase survivability the MRAV-5 is equipped with the Chainmail Phase 2 active protection system. Chainmail includes an F/G band fire-control radar with four flat-panel antennas mounted on the vehicle, with a 360-degree field of view. When a weapon is fired at the vehicle, the internal computer uses the signal from the incoming weapon and calculates an approach vector. Once the incoming weapon is fully classified, the computers calculate the optimal time and angle to fire the neutralizers to intercept the threat at a distance of 5 to 30 meters from the protected vehicle.
The response of the Phase 2 systems comes from two rotating launchers installed on the sides of the vehicle.The launchers are normally stowed behind armored plating and only deploy when a threat is detected.The launchers fire the neutralizing agents, which explode in front of a threat forming a dense "curtain" of reactive explosive fragments within one millisecond. The system is designed to have a very small kill zone, so as not to endanger troops adjacent to the protected vehicle. Due to its use of reactive materials Phase 2 is considered roughly fifty times more effective then the first generation system on other LG Defense vehicles. Additionally, the system can track and defend against several simultaneous threats from different directions.
