Full specifications

Performance

Speed, range, altitude and engagement capability.

Performance specifications
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.	1,038 km/h Stronger than 70% of trainers
Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.	0.9 Mach Stronger than 45% of trainers
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.	1,300 km Stronger than 16% of trainers
Service ceiling Maximum operating altitude. Higher gives energy advantage and sensor horizon.	15,240 m Top 9% of trainers

Physical

Dimensions, weight and crew.

Physical specifications
Length Overall length including gun/probe where applicable.	13 m
Wingspan Wingtip-to-wingtip span.	9.94 m
Empty weight Weight without fuel, ammunition or crew.	3,790 kg
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.	5,650 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	2

Propulsion

Engine, power and fuel.

Propulsion specifications
Engine Powerplant model and type.	2x Ishikawajima-Harima XF3-IHI-30 turbofans
Engines Number of engines. Twin-engine gives redundancy at higher cost.	2
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Turbofan

Program

Cost, production scale and operators.

Program specifications
Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.	208 Stronger than 75% of trainers
Operator countries Number of countries operating the system. More operators means broader support ecosystem.	1 Stronger than 13% of trainers
