Unit Price-6 million
The original AL-78 was nothing more than a refitted black market T-72 used in guerrilla operations against the COM-BLOC which the USSI was fighting against at the time. However, after independence, the need for a proper light tank was recognized as the Ikruchystani Liberation Army had become a regular army and not a guerrilla force. The inadequacy of the original AL-78 armor was demonstrated during the Kazerghstani Intervention as well as during ULN War Games where AL-78s were frequently destroyed by primitive IEDs and shoulder-fired AT weapons. The USSI High Command deemed this unacceptable and demanded that the Ikruchystan Arms Development Division develop proper armor for the AL-78. The addition of the new armor as well as: improved secondary armament, better suspension, and engine resulted in the AL-78 Mk.11
Concept
The AL-78 Mk.11 was designed on the same concept that the original AL-78 was: Maximum survivability and efficiency. However, by 2011 the battlefields that the AL-78 would primarily be operating on had changed significantly. By this time the AL-78 would most likely be operating in head-to-head combat with MBTs, AAVs and all the other equipment of a modern military, as well as in peace-keeping operations in locations including urban settings. As such the survivability concept became geared more towards resisting hits and increasing mobility rather than simply hoping to avoid being hit.
As such the survivability concept consists of 5 stages:
1) Don't be seen-Signature Management
2) Don't allow the enemy to respond-First strike capability
3) Don't be hit-Active Defense System
4) Don't be penetrated-Advanced IMMAP armor platform
5) Don't be killed-Spall liner system
Design and Production
The Ikruchystan Arms Development Division (IADD) was awarded the contract by the government. 2.5 billion dollars were allocated for the redesign and reproduction process. The IMMAP armor system and other new features were completed by February 2011 and the Mk.11 upgrade kits as well as entirely new tanks were put into production on March 14th 2011.
Dimensions and General Info
Weight: 40 tonnes fully loaded
Length: 8 metres, gun forward
Width: 3.3 metres
Height:2.25 metres
Crew:3, Gunner, Driver, and Commander
Power to weight ratio: 27.5hp/ton
Armament: 120mm smoothbore, 25mm coaxial autocannon, and 14.5x114mm heavy machine gun
Engine: 4 stroke, 12 cylinder, 1100hp, water cooled diesel
Armor: IMMAP advanced modular composite
Defensive Capabilities: Smokescreens, mine destroyer, ADS hard/soft kill anti-missile system
Range: 750 km and up to 1000 with external tanks
Weapons
120 mm refitted Rheinmetall smoothbore cannon with autoloader and 45 round ammo capacity. Capable of firing HEAT and other ATGMs.
25mm coaxial auto-cannon for use against soft skinned vehicles and infantry. The remote firing mechanism allows the gun to be fired without the crew ever leaving the protection of the turret. The smaller caliber gun is useful in situations where collateral damage must be limited, which is an important concern on the modern battlefield. It can also be used to help spot for the main gun when 120mm ammunition is limited. (100 rounds)
14.5x114mm machine-gun for use against low-flying aircraft as well as soft-skinned vehicles and infantry.(3000 rounds)
Electronics
The AL-78 is equipped with auto-stabilization, remote firing systems, and computer assisted target acquisition. This improves the performance of the weaponry drastically as it allows the AL-78 to fire on the move, at the most threatening targets.
The ADS Hard/Soft Kill System can be utilized to eliminate high-risk missile threats, such as ATGMs before they are able to reach to the tank.
The Soft-Kill System uses an infrared lamp mounted on the tank. This lamp projects high levels of Infrared radiation, "blinding" the missile. It disrupts the missile's laser-guided operations, including target acquisition, tracking, and guidance.
The Hard-Kill System uses twin batteries of counter-measure short range missiles mounted on the tank to intercept and destroy the projectile before it hits the tank.
The AL-78 is equipped with thermal imaging to use in low-light and low-visibility environments. It provides a 180-degree view around the front of the tank and is particularly useful when enemy forces use smoke to mask their movements, as the infrared is unaffected by the smoke.
Armor
The armor for the AL-78 was completely redesigned after witnessing its' poor performance during the Kazerghstani Intervention as well as ULN exercises.
The AL-78s IMMAP armor is a development of the AMAP program. It was chosen for its' superior modularity as well as reduced weight and superior strength.
The armor consists of:
-SLAT cage (optional)-For basic protection against RPGs, a stiff cage that can be placed around the outside of the vehicle.
-ERA-Reactive armor plates capable of stopping shaped charges such as ATGMs and RPGs.
-Silicon Carbide Ceramic Armor-Silicon carbide is an extremely hard ceramic. It is caged in a steel matrix, and is very brittle. When a HEAT round penetrates, it causes extremely asymmetric pressures causing the HEAT round to defeat itself.
-Mat 7720 Aluminium-Titanium Alloy-Chosen for its' lower weight and superior protection. This newly developed alloy needs only 38% as much weight as RHA (Conventional Steel Armor) for the same level of protection. It is combination of aluminium and titanium
-NERA-Reactive armor plates capable of stopping shaped charges such as ATGMs and RPGs.
-Spaced Armor-For additional protection against HEAT rounds and ATGMs.
-Spall Liner-Designed to protect the crew even if the armor is breached, the spall liner guards the crew against fragments and the effects of HEAT and HESH rounds.
The armor is assembled in this order:
-ERA
-Mat 7720
-NERA
-Mat 7720
-Silicon Carbide
-Mat 7720
-Spaced Armor
-Mat 7720
-Spall Liner
Range and Survivability
The AL-78 has superb range-up to 750km with the 3 integrated fuel tanks and up to 1000km with additional fuel.
The array of weapons allows the AL-78 to be able to survive against a wide array of threats without ever needing support. In integrated weapons have been proven by war to be effective against: APCs, light tanks, soft shelled vehicles, infantry, attack and transport helicopters, and even low flying cargo aircraft.
Because of all these weapons and its superior range the AL-78 can strike deep behind enemy lines and remain there wreaking havoc until your frontal forces can meet up with them.
Engine and Transmission
The AL-78 uses a four-stroke, 12 cylinder, water cooled, 1100 hp engine capable of producing speeds of up to 100 km per hour on roads and 70 km per hour cross country. The diesel engine is more efficient than conventional gas engines. It uses a direct injection system where direct injection injectors are mounted in the top of the combustion chamber. This system is 15-20 more efficient than a typical diesel engine. A major issue with diesel engines is gelling, which is where the diesel freezes in the fuel line and cuts off fuel supply to the engine, was solved by using modern additives and installing low-output electric heaters around the fuel line.
The transmission is The ISU, which is installed on every bogie on the tracks, allows them to be individually controlled. Thus, the AH-92 will be able not only to "sit", "stand" and "kneel", but to "lean" towards a side or a corner as well. "Sitting" gives the tank a lower profile and offers better handling over roads. "Standing" gives the vehicle higher ground clearance and allows it to have better maneuverability over rough terrain. "Kneeling" increases the amount of angle that the tank's gun barrel can elevate and depress, which allows the tank to fire its main gun downhill and give it greater ability to engage low-flying helicopters. The new suspension unit also gives the tank an advantage when traveling on uneven terrain as the bogies can be adjusted on-the-fly to lessen vibration, as well as being lighter and simpler to maintain than the HSU.
