From AH-64D to AH-64E: A Significant Upgrade
Previously known as the AH-64D Block III, the AH-64E was re-designated in 2012 following substantial improvements. These upgrades include:
- More powerful engines
- Enhanced transmission systems
- Advanced Longbow fire control radar
- Unmanned Aerial Vehicle (UAV) integration capabilities
The U.S. Army began receiving the upgraded AH-64E models in 2011. By plan, a total of 634 older AH-64D helicopters are to be upgraded to the E standard, with an additional 56 helicopters being newly built.
Global Operators of the AH-64E Apache
With its outstanding capabilities, the AH-64E has gained widespread interest across the globe. Key international operators include:
- India – Ordered 22 units (deliveries began in 2019)
- Indonesia – Purchased 8 units
- Qatar – Acquired 24 helicopters
- South Korea – Bought 36 units
- United Arab Emirates – Ordered 30 aircraft
- United Kingdom – Requested the remanufacture of 50 WAH-64D Longbow Apaches to AH-64E standard
Although Iraq initially ordered 24 units in 2014, the deal was later canceled.
Power and Propulsion: Enhanced Engine and Rotor Design
The AH-64E is equipped with General Electric T700-GE-701D engines, producing 1,994 shp each—an upgrade from the 1,800 shp in earlier variants. These are paired with:
- Upgraded transmission to manage the additional power
- New composite rotor blades, capable of surviving hits from 23 mm anti-aircraft guns
- Maximum flight speed of up to 300 km/h (186 mph)
These advancements provide better maneuverability, speed, and durability in hostile environments.
Avionics and Sensor Upgrades: Night and UAV Operations
The Apache Guardian is packed with next-generation avionics and sensors, greatly enhancing its operational flexibility. Key improvements include:
- Upgraded night vision and infrared systems
- Integration with unmanned aerial vehicles (UAVs) for reconnaissance and targeting
- Helmet-mounted sighting systems for both pilot and gunner
- Multi-role fire control radar with fog and smoke penetration capabilities
These systems allow the AH-64E to identify, engage, and destroy enemy targets under all weather and lighting conditions.
Survivability and Crew Protection
Designed with combat survivability in mind, the AH-64E incorporates several features to protect its two-person crew:
- Armored airframe resistant to 12.7 mm rounds
- Composite rotor blades that can endure 23 mm gunfire
- Crash-resistant crew seats
- Infrared-suppressing exhausts to minimize heat signature
- Chaff and flare dispensers for missile evasion
- Flat-plate canopy with boron armor for cockpit defense
These features enhance the helicopter’s ability to withstand attacks and safely return from missions.
Firepower and Weapons Configuration
The AH-64E is among the most heavily armed attack helicopters in the world. Its standard weapon systems include:
- 30 mm M230 chain gun with 1,200 rounds
- Four stub-wing hardpoints capable of carrying a range of munitions tailored to mission needs
Primary Armament Options:
- Up to 16 AGM-114R Hellfire II anti-tank missiles
- AIM-92 Stinger / AIM-9 Sidewinder / Mistral air-to-air missiles (up to 4)
- AGM-122 Sidearm anti-radiation missiles (up to 2)
- Hydra 70 rocket pods (up to 4 pods, 19 rockets each)
This array of weapons makes the AH-64E effective against armored vehicles, enemy helicopters, radar systems, and ground troops.
Longbow Radar: Target Acquisition and Fire-and-Forget Capability
The optional AN/APG-78 Longbow radar system remains a game-changer. When installed, it allows:
- Fire-and-forget use of Hellfire missiles
- Detection and tracking of up to 12 targets simultaneously
- Engagement through smoke, fog, and dust—conditions that render IR or TV sensors ineffective
This radar significantly enhances the Apache's lethality and situational awareness on complex battlefields.
AH-64E Crew Configuration
The two-person crew consists of:
- Pilot (seated in the rear)
- Gunner/Co-pilot (seated in the front)
Both crew members utilize independent sensor systems, enabling them to engage targets individually or collaboratively. Their helmets are integrated with advanced display systems, allowing targeting simply by looking at the object of interest.
Conclusion: A New Standard in Attack Helicopter Warfare
The AH-64E Apache Guardian sets a new benchmark in rotary-wing combat aviation. With its combination of powerful engines, advanced targeting systems, composite protection, and unrivaled firepower, the AH-64E remains a critical asset in the U.S. Army’s arsenal and is rapidly gaining ground as a preferred export model for allied nations.
In modern warfare scenarios where speed, versatility, and survivability are non-negotiable, the AH-64E proves to be a lethal force multiplier—redefining what an attack helicopter can achieve on the battlefield.
