K1A2

An upgraded standard of South Korea's indigenous K1 tank, adding a digital fire control system, improved armor and a hunter-killer sighting system closer to the newer K2 Black Panther. It remains a mainstay of the ROK Army alongside the K2.

Full specifications

Performance

Speed, range, altitude and engagement capability.

Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.: 65 km/h

Stronger than 39% of main battle tanks
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.: 500 km

Stronger than 59% of main battle tanks
Power-to-weight Engine power per tonne of vehicle weight. Higher means better acceleration and cross-country mobility.: 21.7 hp/t

Stronger than 51% of main battle tanks
Muzzle velocity Projectile speed leaving the barrel. Higher means flatter trajectory and better armor penetration.: 1,650 m/s

Stronger than 26% of main battle tanks

Firepower

Armament, payload and guidance.

Main armament Primary weapon: main gun, cannon or missile type.: 105 mm KM68A1 rifled gun
Secondary armament Additional weapons: coaxial MG, remote weapon station, gun pods.: 12.7 mm + 7.62 mm coaxial machine gun
Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better — ammunition commonality matters.: 105 mm
Ammunition Rounds carried (main gun) or standard magazine capacity.: 47

Stronger than 86% of main battle tanks

Protection

Armor, countermeasures and survivability.

Armor Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.: Composite armor with modular appliqué
Reactive armor Explosive reactive armor (ERA) blocks that disrupt shaped-charge jets.: No
Countermeasures Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.: smoke grenade launchers
NBC protection Sealed crew compartment with overpressure filtration for nuclear/biological/chemical environments.: Yes

Physical

Dimensions, weight and crew.

Length Overall length including gun/probe where applicable.: 9.67 m
Width Overall width — matters for rail/road transport of vehicles.: 3.6 m
Height Overall height. Lower profile is harder to spot and hit for ground vehicles.: 2.25 m
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.: 51,000 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.: 4

Propulsion

Engine, power and fuel.

Engine Powerplant model and type.: MTU MB871 Ka-501 diesel
Engine power Engine output power. Higher moves more weight faster.: 1,200 hp

Stronger than 53% of main battle tanks
Fuel capacity Internal fuel volume.: 1,200 L
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…: Diesel

Sensors & avionics

Radar, sensor suite and datalinks.

Sensors IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.: digital fire control system, hunter-killer sighting
Thermal imaging Thermal sights for night and obscured-visibility operations.: Yes

Program

Cost, production scale and operators.

Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 1

Stronger than 23% of main battle tanks
