Development
Developed from captured Wolfhound tanks which were purchased from Akiteiwa in limited quantity. Modified to better fit domestic production capabilities and available technologies.
Design choices
Armament
122mm L/40 rifled gun
- Ballistically equivalent to D-25T/D-49 122mm guns.
- Chosen over available 107mm rifled gun with better AT performance due to Kasibaar having strong beliefs in tanks being for infantry support primarily, anti-tank use is secondary.

Prototypes
Production models
Type 61A
- Base model
- Unstabilised gun, gun never received a stabiliser in domestic models for cost reasons.
- Underpowered engine
- Limited range
- Underpowered horizontal/azimuth turret traverse motor.
Type 61A/1 (1968)
- Up-armoured hull, additional 76.5mm plate welded to UFP
- V12 turbo diesel
- New more reliable transmission
- Updated 122mm L/40 rifled gun
- Increased maximum pressure to allow use of new "overpressure" APDS round.
- Updated breech to be more space efficient.
- New elevation and azimuth turret motors increasing traverse speeds.
- Air conditioning becomes standard
Type 61A/2 (1979)
- Passive IR
- First generation laser rangefinder mounted externally
- Updated 122mm L/40 rifled gun
- Increased pressure and barrel life
- First generation APFSDS
Type 61B (1985)
- Major overhaul of hull and turret construction
- Frontal hull slope re-designed, 153mm of armour @68°.
- New Gr'aan torr (Anglic Lit.: Grand tower, Anglic: Large turret), 300mm of armour along frontal arc.
- Solid state fire control computer and linked fire control system
- Stabilised articulated telescopic sight for gunner
- Integrated laser rangefinder
- Automatic lead calculation
- First generation thermal sight.
- Initially only 1 in 5 vehicles (command vehicles only) received TV thermal sights, the remainder received TV Infrared optics as night fighting equipment.
- Stabilised articulated telescopic sight for gunner
Type 61B/1 (1991)
- New 122mm L/45 rifled gun
- Some vehicles did not receive this gun initially due issues producing steel of sufficient quality to withstand desired pressures. A stop gap upgrade for the short 122mm was used with a cut down thermal sleeve.
- Increased operating pressure, larger propellant charge
- Longer barrel
- Equivalent to U5TS 115mm.
- Thermal sleeve
- New commanders independently rotating periscope, first generation thermal, magnified optic, unity sight and laser rangefinder.
Type 61C (2005)
- Limited service. Designed to bring commonality with Type 04 medium tank (replacement for Type 61 family) that entered service the year prior.
- ERA kit along frontal arc of turret and hull on some vehicles.
- Muzzle reference device
- Second generation thermal sights
- New suspension
- Six roadwheels
- New V12 turbo diesel
- required hull to be lengthened and engine deck to be raised
