United States Legacy Boeing
AH-64D Apache Longbow
The upgraded successor to the original AH-1G Apache, introducing the AN/APG-78 Longbow millimeter-wave fire-control radar in a distinctive mast-mounted dome and a glass cockpit. It served as the U.S. Army's primary attack helicopter for two decades before being progressively remanufactured into the AH-64E.

Availability & export
US ITAR-controlled
Export needs U.S. State Dept (DDTC) approval; end-use & re-transfer restrictions apply.
Channel: Foreign Military Sales (FMS) or Direct Commercial Sale
Fielded & proven
Established · 11 operators
In service since 1997. Status: legacy · ~800 built.
Lifecycle cost (est.)
$65M – $91M
Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price.
Interoperability
Derived guidance from public data — export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.
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.
- 265 km/h Bottom 8% of helicopters
- Cruise speed
Sustained economical speed. Determines transit time to station.
- 260 km/h Stronger than 55% of helicopters
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 480 km Stronger than 25% of helicopters
- Service ceiling
Maximum operating altitude. Higher gives energy advantage and sensor horizon.
- 6,400 m Top 8% of helicopters
- Rate of climb
How fast the aircraft gains altitude. Higher means better energy recovery in combat.
- 13 m/s Stronger than 77% of helicopters
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- 30 mm M230 chain gun
- Hardpoints
External stations for weapons and pods. More means bigger and more flexible loadouts.
- 4 Stronger than 41% of helicopters
- Weapons payload
Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.
- 771 kg Stronger than 28% of helicopters
Protection
Armor, countermeasures and survivability.
- Armor
Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.
- Crew compartment boron-carbide armor plating and crash-resistant seats
- Countermeasures
Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.
- AN/APR-48 radar warning receiver, chaff, flares, AN/AAR-11 missile warning system
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 17.73 m
- Height
Overall height. Lower profile is harder to spot and hit for ground vehicles.
- 3.87 m
- Empty weight
Weight without fuel, ammunition or crew.
- 5,165 kg
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 10,107 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 2
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- 2x General Electric T700-GE-701C turboshaft, 1890 hp each
- Engines
Number of engines. Twin-engine gives redundancy at higher cost.
- 2
- Engine power
Engine output power. Higher moves more weight faster.
- 1,890 hp Stronger than 53% of helicopters
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Turboshaft
Sensors & avionics
Radar, sensor suite and datalinks.
- Radar
Primary radar. AESA (active electronically scanned array) is the current state of the art.
- AN/APG-78 Longbow millimeter-wave fire-control radar
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- AN/ASQ-170 Target Acquisition Designation Sight, AN/AAR-11 pilot night vision sensor
- Thermal imaging
Thermal sights for night and obscured-visibility operations.
- Yes
Program
Cost, production scale and operators.
- Unit cost
Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.
- $26,000,000 Stronger than 65% of helicopters
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 800 Stronger than 80% of helicopters
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 11 Stronger than 77% of helicopters
