Background
Even as the MBT-143 was in its early development phases, the idea to develop an infantry fighting vehicle based on it was suggested. The Abir already had a front mounted engine, sufficient space, and a rear facing clamshell door.
The IFV-143 Gvira(Lady or Mistress in Hebrew) is a highly protected infantry vehicles, meant to carry and support infantry into combat. With its tank like armor, it provides excellent protection for both its crew and passengers. Its varied armaments allow it to engage and defeat armor and infantry. For forces operating the Abir or Kotesh, the Gvira offers parts communality and easier logistics and training.
General Design
The hull design of the IFV-143 is nearly identical to that of the tank it originated from. The engine and transmission are mounted to the front and right, with the driver to their left. The frontally mounted engine serves to improve crew survivability and allows more space at the rear of the vehicle, needed for the troop compartment and clamshell door.
The turret is located behind the driver, with commander and gunner either side of the gun and coaxial armaments. The troop compartment is to the rear, and has two rows of 4 seats each adjacent to the hull sides, and a ninth seat in the middle, nearest the turret ring. The commander of the infantry squad is usually seated there.
Armament
The IFV-143 is heavily armed. It is equipped with a fully digital fire control system and electric turret traverse and stabilization. The FCS includes a gunners day and night thermal sight, and a commanders independent 360 degrees rotating day and night thermal sight. The system is capable of pixel lock. The sights are capable of displaying BASTION battle management data over the real time image. The commander can "slave" the gun controls, and has full functionality of the FCS from his position.
The main weapon is a 100mm low velocity smooth bore gun capable of firing not only standard HE rounds but also 100mm gun launched missiles such as the Shcwerpunkt "Hunter" GLATGM. The 100mm can be used to engage the full spectrum of ground targets from tanks to infantry at ranges of up to 8,000 meters. Ammunition is loaded by a carousel type autoloader.
Coaxially mounted to the 100mm is a 30mm L80 cannon, firing a mix of AP and HE rounds at a rate of 350 rounds per minute. Firing in short bursts it is lethal to infantry and lightly armored vehicles and saves the 100mm ammunition for harder targets.
Also coaxially mounted is a 7.62 FN-MAG machinegun, used to engage infantry and soft targets up to 1,000 meters away.
The commander has full control over the main and coaxial armaments. In addition, he has two other weapon systems operated solely by him.
A 7.62mm machinegun in a pintle mount near the commander's hatch allows for engagement of infantry at close ranges. The mount is simple and allows for a 270 degree fire arc as well as high elevation for AA fire.
In addition to the machinegun, the commander also controls the 12 tube close range grenade system.
The 80mm grenades launched by this system can engage infantry in close ranges (60 meters) and more importantly screen the vehicle against threats. The grenades are fired from a control panel in the commander’s compartment. Types of ammunition available for this system are White Phosphorus, HE-Fragmentation, IR-screening smoke, IR-Decoy, Less than lethal tear gas and less than lethal “flash-bang”.
Protection
The IFV-143 has a very sharply angled glacis plate and V shaped hull bottom. The turret is similar to that of the WUAP-IFV, a trapezoid shaped design. Unlike WUAP, the Gvira has a wider turret, with added plates of composite and reactive armor. The IFV-143 is protected against high caliber tank guns on the front hull and turret face, and against high caliber automatic cannons on the turret sides and rear.
In addition to the passive and reactive protection suites, the IFV-143 is also protected by the “Iron Tide” APS. “Iron Tide” is modular soft and hard kill system designed to operate with the BASTION battle management system and take full advantage of the systems of each specific vehicle it is mounted on.
NBC protection for the IFV-143 is provided by an overpressure system and individual NBC protection for each crew member. The individual protection is in the form of 12 air filtering systems running directly to the masks and NBC overalls of the crew. The air is not only filtered but also cooled. If this system fails the IFV can use the over pressure system along with standard gas masks. The vehicle is buttoned and an overpressure is created by pumping air into the tank through filters. This keeps contaminated air out and when combined with the use of personal masks allows continued operations in contaminated areas.
Crew and vehicle survivability
The IFV-143 has a Kevlar lining in the crew compartments to minimize spalling. The front mounted engine layout of the allows for a rear exit. The rear exit hatch is a clamshell design and can be opened electrically or manually. The crew can use it to dismount while protected by the vehicles mass. It also allows them to mount the IFV without climbing to the turret and exposing themselves.
A fire suppression system is installed in the fighting compartment, crew compartment, engine compartment and ammo storage units. The system has 10 visual and thermal fire detectors and 8 BCF canisters. The canisters are located in the turret (2), troop compartment (2), driver compartment (1) engine compartment (2) and ammo storage units (3). The entire system is controlled from the gunner’s compartment, with the engine canisters also being operated from the driver’s compartment. Diesel fuel for the engine is stored in 5 tanks in the front and back of the IFV, with cutoff valves allowing the use of each tank separately.
A mine-protection plate made of titanium is available for the IFV-143. This plate weighs several tons and reduces the ground clearance to 28cm, but dramatically improves the survivability of the vehicle and crew in case of a large explosion under the hull. The crew and passenger seats are all of the suspended type, to protect the crew from explosions under the hull.
Mobility
The IFV-143 is a heavy vehicle at 70 metric tons, but it uses a powerful engine coupled to an advanced transmission to maintain good performance both on and off road. In fact, due to the lighter turret, the IFV-143 has better performance than the tank that fathered it.
The NMC AVM2300 is a Horizontally Opposed, Twin Turbocharged V10. The injection system is based on pre-combustion chambers, allowing multi-fuel use. Cooling is provided by a pressurized close circuit cooling system. Twin turbochargers are installed to maximize performance. A filtering system is installed to allow operations in fine-dust conditions. The engine has a preheating system for the oil and can operate at temperatures of -46C to +52C. The engine produces 2300 bhp at 3000rpm.
Coupled to the engine is a semi-automatic hydro-mechanical transmission with 5 forward gears, 2 reverse gears, neutral gear and pivot. Mechanical brakes are built on to the output shafts, which are transverse to the input. Propulsion drive is via a torque converter with lock up clutch, shifting and reversing gear to be shifted under load with planetary gear sets, multidisc brakes and clutches. Steering drive is infinitely variable by a hydrostatic-hydrodynamic superimposed steering system. The transmission brake is a combined hydrodynamic-mechanical brake system as service brake, without parking and auxiliary brakes.
The InArm suspension system developed by Horstman incorporates dual piston compressible struts into the suspension arms. The system also has a central control to adjust the amount of fluid in each InArm unit. The hydraulic units act both as springs and dampers, and the system allows the driver to lower and raise the ground clearance given by each arm. In total there are 7 pairs of road wheels on each side of the suspension, with 4 return rollers. The tracks are 670mm wide and do not have rubber soles.
Communications and Networking
The IFV-143 has a standard NPS combined internal/external communications system.
Networking for the Gvira is provided by the BASTION system. BASTION is a battlefield management system for units ranging in size from platoons to brigades.
Crew Amenities
The IFV-143 is equipped to support its crew and passengers in long term operations during fighting and when buttoned. A specially designed sun and rain plastic canopy can be raised above the commander hatch to ease waiting periods in harsh weather. An air-conditioning system is connected to the NBC protection system and can flow warm or cool air into the overalls and NBC masks of the crew. For the passengers, an extra A/C system is available when not using the masks(as the passengers rarely wear overalls) Two 75 liter NBC protected water tanks located in the rear hull are connected to a heating/cooling unit and supplies hot or cold water thorough a tap in the troop compartment corridor. Rations are kept in water tight compartments in the fighting compartment itself as well as in the rear corridor. 4 days' worth of rations can be carried in this way. The IFV has a special storage compartment holding an electric cooking pen, an electric cigarette lighter, plates and utensils.
