We needed to produce a tank that was both powerful and easy to mass produce (our most powerful tanks have been bought off other nations). This is the end result and we would like to know if everything is actually plausible or if parts are unrealistic and needs changing. Thanks in advance for any good advice.

AH-21 Main Battle Tank
Crew: 3 (Driver, gunner, commander)
Weight: 52 tonnes
Engine: 1,300hp SACM V8X-1500 diesel
Transmission: SESM ESM 500 automatic transmission, 5 forward and 2 reverse gears
Track: Metallic with RSMh, with rubber-tyred road wheels
Suspension: Torsion bar
Radio: Receive/transmit, telephone
Dimension: Length: 10.28 m; Height: 2.30 m; Width: 3.450 m
Ground Pressure: 0.771 kg/cm 2
Cruising Range: 400-500km
Speed: Max road 57 km/h; max off-road 45 km/h; average cross-country 35 km/h; max swim N/A
Fording Depths: 1.4 m unprepared; 2.4 m with snorkel
Main Gun: 145 mm A57BX Electro Thermal Chemical Cannon
Rate of Fire: 8-9 rounds/min
Elevation/Depression: +14 to -6 degree
Auxiliary Weapon: One coaxial 7.62 mm machine gun; one 12.7 mm air-defence machine gun
Fire Control: ISFCS with laser rangefinder input, onboard computer, wind sensor, and control panel
DESIGN FEATURES
The AH-21 uses a conventional layout with three crewmembers. The driver compartment is located in the left front; the turret is mounted in the middle and the engine compartment in the rear. There are six smaller road wheels on each side.
ARMAMENT: The AH-21 has 145mm ETC Cannon with autoloader of Andrehervian JXK2 design. By introducing the autoloader to reduce the crew to three men, more rounds are available for the higher rate of fire. The tank can carry 42 rounds, 22 of them stored in the carousel of the autoloader, and the gun can fire at 8-9 rounds per minute. The turret is equipped with a coaxial 7.62mm machine gun designed for anti-infantry use and a 12.7mm air-defence machine gun for low flying aircraft.
ARMOUR: The AH-21 incorporates steel encased depleted uranium armour. Armour bulkheads separate the crew compartment from the fuel tanks. The top panels of the tank are designed to blow outwards in the event of penetration by a HEAT projectile. The tank is protected against nuclear, biological and chemical (NBC) warfare. The turret is protected with second generation Chobham armour. A nuclear, biological and chemical (NBC) protection system is located in the turret bustle.
FIRE CONTROL AND OBSERVATION: The commander's station is equipped with six periscopes, providing 360 degree view. The Raytheon Commander's Independent Thermal Viewer (CITV) provides the commander with independent stabilised day and night vision with a 360 degree view, automatic sector scanning, automatic target cueing of the gunner's sight and back-up fire control.
The AH-21 tank has a two-axis Raytheon Gunner's Primary Sight- Line of Sight (GPS-LOS) which increases the first round hit probability by providing faster target acquisition and improved gun pointing. The Thermal Imaging System (TIS) has magnification x10 narrow field of view and x3 wide field of view. The thermal image is displayed in the eyepiece of the gunner's sight together with the range measurement from a laser rangefinder. The AndreArms Laser Systems Eyesafe Laser Rangefinder (ELRF) has a range accuracy to within 10m and target discrimination of 20m. The gunner also has an AndreArms Model 939 auxiliary sight with magnification x8 and field of view 8 degrees.
The Andrehervian technology division supplies the digital fire control computer. The fire control computer automatically calculates the fire control solution based on: lead angle measurement; bend of the gun measured by the muzzle reference system; velocity measurement from a wind sensor on the roof of the turret; data from a pendulum static cant sensor located at the centre of the turret roof. The operator manually inputs data on ammunition type, temperature, and barometric pressure.
The driver has either three observation periscopes or two periscopes on either side and a central image intensifying periscope for night vision. The periscopes provide 120 degrees field of view. The AHTD’s Driver's Vision Enhancer (DVE), AN/VSS-5, is based on a 328 x 245 element uncooled infrared detector array, operating in the 7.5 to 13 micron waveband. A Raytheon Driver's Thermal Viewer, AN/VAS-3, is installed on the AH-21 tank for Desert and other harsh environments.
