The Bisonic Defense Initiatives Agency (BDIA) has announced the development of the GT-6 MBT, a further development of the GT-1. When the GT-1 was first released, it was easily well ahead of any other. But with products from Soviet Bloc and Kazahstania catching up, it was decided to create a new MBT to counter them.
Armament
The GT-6 armament includes an electro-thermal 135mm gun, stabilized in two axes and fitted with a thermal sleeve. It hits with the force of a 155mm gun. The gun tube can be replaced without dismantling inside the turret. The gun can fire a variety of ammunition including APDS (Armour Piercing Discarding Sabot), HEAT (High Explosive Anti-Tank), HE-FRAG (High Explosive Fragmentation) as well as shrapnel projectiles with time fuses. A special scramjet round was also developed (more details further down).
The 135mm gun can also fire the AT-17 Slicer anti-tank guided missile system. The range of the missile is 100 - 6,000 m and takes 14.7 sec to reach maximum range. The system is intended to engage tanks fitted with ERA (Explosive Reactive Armour) as well as low-flying air targets such as helicopters, at a range of up to 7 km. The missile system fires either the 9M119 or 9M119M missiles which have semi-automatic laser beamriding guidance and a hollow charge warhead. Missile weight is 28.4 kg.
The guns 15 rpm automatic loader will feed both ordnance and missiles.
A 45mm 2A77 autocannon has been installed to allow quick engagement of other armored fighting vehicles. Ammunition load is 470 AP (Armour-Piercing) or HE rounds. Rate of fire is more than 300 rounds/min and range is 1,500 to 2,200m.
There are 12 Yastreb ATGM's towards the rear of the turret. Yastreb is a radar guided ATGM with a range of over 5km that easily penetrates the amror of the M1A2 or similar tanks with its 1600mm penetration.
Also fitted is a coaxial 7.62 mm Pecheneg-T machine gun and a Kord 12.7 mm air defense machine gun. A 5.45 mm A-101M assault rifle is carried on a storage rack.
Scramjet Round
http://img38.exs.cx/img38/4269/p40colucci.jpg
The scramjet, like common jet engines, burns fuel mixed with compressed atmospheric oxygen. However, unlike traditional jets, the scramjet has no compressor disks or other moving parts to compress the air. Hot air entering the scramjet inlets at four times the speed of sound, ignites the fuel and sustains combustion, so the scramjet itself contains pure fuel without wasting weight and volume of a separate oxidizer.
As it emerges ignited from a cannon barrel, a scramjet-powered tank round could produce thrust in flight to extend its range or sustain its penetrating power all the way to the target.
Compared to unpowered kinetic energy tank rounds that slow down and lose penetrating power to aerodynamic drag, a scramjet powered round could sustain its tank-penetrating power over longer ranges, or enable a smaller, lighter gun to achieve the same result.
With no moving parts, the scramjet engine burns fuel with the compressed, superheated air encountered at Mach 5—the muzzle velocity of tank guns.
Timing fuel combustion to the desired flight profile makes it possible to sustain the kinetic energy and penetrating power of tank rounds at extended ranges in direct-fire applications. Alternatively, the scramjet could extend the range of cannon rounds for indirect fires.
Accelerated to Mach 5 by the time it leaves the 135 mm gun of the GT-6 tank, the standard 6BM34M kinetic-energy round uses a finned “dart” to penetrate opposing tank armor and devastate the crew compartment without an explosive warhead. Despite their acknowledged effectiveness, kinetic-energy rounds lose about 100 miles-per-second velocity over 2 kilometers, due to drag.
Since kinetic energy declines with the square of the velocity, armor penetration falls off at extended ranges. A scramjet propelled round could sustain the velocity and penetrating power of a tank gun round all the way to its target. Upon its Mach 7 impact, the tungsten penetrate would annihalate almost any tank.
Armor:
Protection of the GT-6 includes an outer layer of Montgomery titanium armor, along with other lightweight composites. This is designed to absorb chaingun rounds of up to 45mm caliber, as well as light rocket launchers (M136, RPG-26, etc.)
The main protection of the GT-6 consists of 2 types off nonexplosive ractive armor- 1 meant for protection from HEAT, and the other, from APFDS.
As Non-Explosive Reactive Armor (NERA) or Non Explosive reactive Armor (NxRA) modules do not use energetic components, and therefore are not consumed when being hit. Therefore, they provide an effective multi-hit protection capability which cannot be obtained by ERA or SLERA. Furthermore, the loads inflicted on the vehicle's structure are much smaller and therefore, such modules can be applied to lighter vehicles. from the reactive armor system. The downside of NERA is that while it is effective against CE threats, its performance is not sufficient when engaging KE threats. Therefore, the GT-1 was forced to have a heavy layer of Tungsten to protect from APFDS. With the GT-6, this is not the case.
For proection against APFDS, the GT-6 has Momentum Transfer Armor- designed to counter KE threats. The system is activated by threat warning sensors that detect an incoming projectile and launch a small steel bar in a direction perpendicular to the flight-path of the approaching threat, effectively neutralizing it.
Protection Against Missiles
The GT-6 is fitted with a wide variety of anti-missile systems, both "Soft Kill" jammers and "Hard Kill" APS.
ARENA-M
The GT-6 features the ARENA-M system, the first available DAS-system, was analysed by TNO-PML in collaboration with TNO-FEL. This systems detects an incoming anti-tank missile and reacts by throwing a cassette containing explosives and fragments towards the missile. Upon detonation of the cassette, the fragments interact with the missile, such that its effectiveness decreases substantially.
Both testings of the effectiveness of the fragments and computer simulation of the suite of events- detection, intercept and residual penetration capability- were performed. This resulted in an assessment of the increased survivability of the vehicle equipped with ARENA-M. The same analyses also gave an idea of the decrease of performance of the anti-tank missile.
The Arena-M system is switched on/off from the commander's control console. Once Arena-M is switched on, all subsequent operations are performed automatically. Apart from the basic automatic mode of operation, exceptionally, the commander can control the system manually, for example, when it is necessary to destroy obstacles or for close-in protection against infantry.
Arena provides protection for a moving or stationary tank in any weather and in any combat environment, irrespective of the angle of impact of the enemy's weapons. The data-processing radars and sights feature a high level of noise immunity. They do not respond to false and random signals, and come into action only in situations where there is a serious threat to the tank or when a weapon fired by the enemy is heading directly towards the tank.
Key difference between this system and regular ARENA is installation of more grenades near the rear of the turret, etc.
Shtora-1
Shtora-2 uses a laser warning device operating in the 0.65-1.6 micron range, comprising of an array of coarse (photo below right) and fine resolution (photo below left) sensors, mounted externally on the turret.
Each of the rough (coarse) laser sensor covers a sector of 135 degrees, while the fine sensor covers a 45 degrees, with 3.75 degrees angle of arrival resolution, and -5 to 25 deg. elevation coverage. The system can automatically slew the turret and gun at the direction of the threat, to optimize the deployment of a thermal smoke screen or activation of active protection systems. The sensor detects laser illuminating and alerts the crew and defensive systems. The warning display provides the commander and gunner with threat warning cueing, by sector (at a resolution of 5 degrees) and at a resolution of 3.75 degrees at the 90 deg. frontal arc. The display also provides jammer and countermeasures status indication. Countermeasures can employ a 81mm thermal instant smoke grenades, which deploy an instant smoke screen at a range of 50-80 meters from the tank, within 1.5 - 3 seconds. The 20 meter wide, 15 meter high screen blocks visual, thermal and laser (0.4 - 14 micron) wave bands. The system also employs a pair of electro-optical jammer, designated TShU1-7, which "hijacks" the missile's command link by feeding the tracker with modulated signals that cause the missile to deviate from its course, and away from its intended target.
Laser Jammer
This system comprises of laser warning devices, a dome shaped sensor installed on the turret's roof-top, and a box shaped Laser Self Defense Weapon (LSDW) which "fires" a laser beam at the illuminating source, either a tank gunner, helicopter or missile launcher. The system employs two modes of operation – the low power mode is used at the general direction of the threat, in a search pattern designed to locate the target's optics. Once locked on a target, the laser switches to high power mode, to defeat the target by blinding the operator or saturating its electro-optical circuits.

TAMS
TAMS is a completely autonomous point defence system optimised for anti-tank missiles. The minimum objective is for the system to knock approaching missiles off-course or initiate the warhead before it hits the vehicle. The mount weighs around 100kg and can be installed on a turret with the minimum of modifications and only requires an electrical power supply from the host vehicle. The armament is a 7.62mm chain-gun with an ROF of 5,000 RPM, an elevation of 90°. They are controlled by a millimetric wave surveillance radar with a circular array coupled to a second millimetric wave lock-on radar whose antennae is mounted between the two gun barrels. The lock-on radar is, essentially, the seeker head developed for the active-homing version of the Vikhr missile. The maximum effective range is 600-900m and the on-board ammunition supply is sufficient for approximately 20 engagements.
These systems allow the GT-6 to deal with several missiles simultaneously
It is also fitted with NBC (nuclear, biological and chemical) protection equipment.
Propulsion:
The G-6 has been upgraded to a 1600 hp turbocharged engine. This engine can be fuelled by T-2 or TS-1 kerosene and A-72 benzine, in addition to diesel. The tank can carry up to 1,600 litres of fuel in the main fuel tanks and fuel drums. The fuel tanks are reinforced with armor plating.
The tank is provided with a snorkel for deep fording and can ford 5 metres of water with equipment which can be deployed in 20 minutes.
The mechanical transmission includes primary reduction gear, two planetary final gearboxes and two planetary final drives. The running gear features torsion bar suspension with hydraulic shock absorbers at 1, 2 and 6 road wheel stations and tracks with rubber-metallic pin hinges.
Fire Control:
The GT-1 is fitted with the 1A5GT fire control system.
The 1A5GT fire control system includes:
- The gunner's 1A43 day fire control system
- A laser range finder
- The driver's TVN-5 infrared night viewer
- A second-generation television sight and automatic thermal target tracker
- An integrated operating system which includes advanced data communications and battle management
- Millimeter wave radar
- Infrared tracking system
- Small supercomputer for processing data
The computer controlled fire control system includes line of sight stabilisation in two axes, a second-generation television sight and automatic thermal target tracker, a laser range finder, an improved thermal night vision system and a dynamic cant angle indicator. The commander's station is fitted with a stabilised panoramic day and night sight. The integrated operating system includes advanced data communications and battle management. Tadiran developed the G-1's communications system, the inter communication system and the VRC 120 vehicular transceiver radio with embedded auxiliary receivers.
Signature Reduction:
Protective systems for reduction of tank signatures are designed for reducing the range and probability of the tank detection by reconnaissance equipment and homing devices of high precision ammunitions.
Measures of making the tank less prone to be detected allow the following:
to reduce the tank thermal signature by 5-7 times;
to reduce the tank radar signature by 3-5 times;
to reduce the tank visual signature by 1.5 times
Navigation:
The GT-1 is fitted with the LIO-N navigation system.
The navigation system is included into the tank control system and serves to automate the fulfilment of interaction between tanks within a tank unit in order to command its manoeuvres. Installation of the LIO-N system in the tank ensures the following:
determining the tank's own coordinates with the help of two satellite systems: GPS NAVSTAR and GLONASS;
collecting (with the help of the standard radio set) information about the location of the subordinate tanks and displaying this information on the screen;
generating, transmitting, receiving and displaying the text information (the information is input with the help of a keyboard and is transmitted through a digital radio channel by using the standard radio set);
storing and processing the pre-determined routes;
providing the driver with information about the movement direction required in order to reach the next route check-point.
Technical characteristics:
accuracy (standard deviation) of determining the tank location coordinates when using the systems:
NAVSTAR - 40 m;
GLONASS - 30 m;
NAVSTAR/GLONASS - 20 m;
number of routes that can be pre-determined - up to 10;
number of check-points in each routes - up to 50;
collection of information about the location of subordinate tanks, transmission of the coordinates of destination points and text information are ensured in military units up to tank battalion level inclusively;
time of transmission and reception of information in the digital radio channel and the communications coverage distance are determined by the characteristics of the standard communications means (for R-173M radio set - within 1 sec at distances of up to 20 km);
accuracy of presenting the current time (with allowance for the time zone) - 1 sec;
readiness time:
at 'cold' start - within 180 sec;
