The K1A1 is an upgraded version of the K1 MBT.

Its lethality and combat firing range are much enhanced

by mounting a 120mm smoothbore gun as its main

armament, improving Gun/Turret Drive System and

adopting a ballistic computer for 120mm ammunitions,

while it retains the K1 MBTs outstanding

maneuverability and technology oriented fire control

system ; 2-axis stabilized sight, a thermal imager usable

at night and in all weather conditions and the hunter-

killer function.

MobilityTo deliver the required horsepower and speed on

demand, the K1A1 is equipped with a turbo-charged 1200horsepower diesel engine providing a power to weight

ratio of 22.6hp/ton. The transmission has a planetary gear

train with 4 forward and 2 reverse speed-modes. Thetransmission is also equipped with a hydrodynamic torqueconverter.

Shifting the automatic transmission through the variousspeed ranges requires only a slight force applied to the

shift selector. This shifting arrangement allows the driver

to concentrate completely on his driving and tacticalmaneuvers. In high gear, the K1A1 can attain a maximum

road speed of approximately 65km/h. The K1A1 can travel

500km without refueling.

To further enhance the K1A1s maneuvering capability, the

vehicle can pivot around its vertical axis within its ownlength at the drivers discretion. This maneuver is

accomplished by permitting one track to move in the

forward direction while reversing the other. Also, its

ground pressure of 0.9kg/cm2, which is equivalent to orlower than that of any 40 ton-class tank, enables it to

successfully maneuver in swamp/marsh zones.

Fire PowerThe K1A1 tanks dual-axis stabilized fire control system is

equipped with day and night vision capabilities, which, inconjunction with the electro-hydraulic gun laying system,

makes it capable of acquiring a target accurately within a

minimum time frame.

ArmamentThe K1A1s main armament is a 120mm smoothbore gun

supported by a 7.62mm(M60E2-1) coaxial machine gunand turret mounted 12.7mm(K6) and 7.62mm(M60D)

machine guns. Normally the commander operates the

12.7mm weapon while the loader fires the 7.62mmweapon. Additionally, the K1A1 tank has two smoke

grenade launchers, mounted on each side of the turret for

instant concealment.

SurvivabilityThe K1A1s unique compact configuration provides thetank with a low silhouette, total height of 2.25m form the

ground to the top of turret roof. It has a chassis ground

clearance of 0.46m, exceptionally high in comparison with

other tanks.The welded hull and turret are designed to give the

vehicle maximum ballistic protection. Crew survivability ismaximized by the adoption of the Special Armor Packagein major areas, which offers greater protection for crew

and equipment against chemical and kinetic energy

projectiles.
