Harpy

IAI's original anti-radiation loitering munition, purely RF-homing and optimized for suppression of enemy air defenses (SEAD). Distinct from and predates the electro-optically-equipped Harop (marketed as 'Harpy 2'), which added man-in-the-loop targeting and far longer endurance. The baseline Harpy remains in IAI's current catalog and export inventory alongside the newer Harpy NG and compact Mini Harpy variants.

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.	185 km/h Stronger than 33% of UAVs
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.	200 km Stronger than 42% of UAVs

Firepower

Armament, payload and guidance.

Firepower specifications
Warhead Warhead mass. Heavier generally means larger effect radius, at the cost of range.	32 kg Stronger than 64% of UAVs
Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable.	High-explosive
Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire.	Anti-radiation homing

Physical

Dimensions, weight and crew.

Physical specifications
Length Overall length including gun/probe where applicable.	2.7 m
Wingspan Wingtip-to-wingtip span.	2.1 m
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.	135 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	0

Propulsion

Engine, power and fuel.

Propulsion specifications
Engine Powerplant model and type.	UEL AR731 Wankel rotary engine
Engines Number of engines. Twin-engine gives redundancy at higher cost.	1
Engine power Engine output power. Higher moves more weight faster.	38 hp
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Piston (Wankel rotary), pusher propeller

Program

Cost, production scale and operators.

Program specifications
Operator countries Number of countries operating the system. More operators means broader support ecosystem.	6 Stronger than 75% of UAVs
