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.

2,338 km/h
Stronger than 66% of fighters
Max speed (Mach)

Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.

2.2 Mach
Stronger than 71% of fighters
Range

Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.

2,200 km
Stronger than 24% of fighters
Combat radius

Distance an aircraft can fly, complete its mission and return without refueling. Roughly a third of ferry range.

800 km
Stronger than 37% of fighters
Service ceiling

Maximum operating altitude. Higher gives energy advantage and sensor horizon.

20,200 m
Top 3% of fighters

Firepower

Armament, payload and guidance.

Main armament

Primary weapon: main gun, cannon or missile type.

1x 23 mm twin-barrel cannon
Hardpoints

External stations for weapons and pods. More means bigger and more flexible loadouts.

7
Stronger than 17% of fighters
Weapons payload

Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.

4,500 kg
Stronger than 22% of fighters

Physical

Dimensions, weight and crew.

Length

Overall length including gun/probe where applicable.

21.59 m
Wingspan

Wingtip-to-wingtip span.

9.34 m
Height

Overall height. Lower profile is harder to spot and hit for ground vehicles.

5.41 m
Empty weight

Weight without fuel, ammunition or crew.

9,820 kg
Combat weight

Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.

14,300 kg
Crew

Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.

Propulsion

Engine, power and fuel.

Engine

Powerplant model and type.

2x Wopen WP-13B II turbojets
Engines

Number of engines. Twin-engine gives redundancy at higher cost.

2
Thrust

Total engine thrust (with afterburner where applicable).

68 kN
Bottom 8% of fighters
Propulsion type

Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…

Sensors & avionics

Radar, sensor suite and datalinks.

Radar

Primary radar. AESA (active electronically scanned array) is the current state of the art.

Type 1471 (Zhuk-8II) pulse-Doppler radar

Program

Cost, production scale and operators.

Units built

Total production run. Higher means proven manufacturing, mature logistics and spares availability.

300
Stronger than 62% of fighters
Operator countries

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