Boeing AH-64E Apache: Guardian

Boeing\'s AH-64E Apache attack helicopter is equipped with a sophisticated suite of technological advancements, including cutting-edge digital connectivity and the Joint Tactical Information Distribution System. It is powered by the robust T700-GE-701D engines, which feature upgraded face gear transmission to handle increased power. Additionally, the AH-64E can control unmanned aerial vehicles and is outfitted with a new composite main rotor blade.

In terms of armament, the Apache is heavily armed and can be armed with up to 16 Hellfire missiles, 76 2.75-inch rockets, and 1,200 30mm chain gun rounds. It boasts a top speed of over 250 kilometres per hour, making it a formidable force on the battlefield.

The Australian government\'s decision to replace the ARH Tiger helicopters with the AH-64E Apache stems from the need for a proven and mature, off-the-shelf manned armed helicopter to provide armed reconnaissance effects in Australia\'s close and deep contested battlespace in support of the Australian Defence Force. To bolster Australia\'s Apache fleet, an additional AU$ 500 million has been allocated for the enhancement of aviation facilities and infrastructure at Townsville.

Delivery of the AH-64E Apaches to Australia is slated to commence in 2025, with initial operating capability expected by 2026 and full operating capability anticipated by 2028. The Boeing-manufactured Apache 64E is a twin-engine, tandem-seat helicopter designed for operations in diverse conditions, both day and night, across a range of climatic environments.

Primarily purposed for locating and neutralizing air defence units, tanks, and armoured vehicles, the AH-64E is armed with a 30mm automatic cannon, wing-mounted 70mm Hydra rockets, and Hellfire missiles. Notably, it offers enhanced sights and sensors, enabling accurate target engagement at extended ranges.

The AH-64E\'s capabilities span Intelligence, Surveillance, Target Acquisition, and Reconnaissance (ISTAR), escort/force protection, and Command and Control (C2). With the Longbow radar above the main rotor blades, the Apache 64E can swiftly detect and classify up to 256 potential targets, display 128 of these to the crew, and prioritize the top 16 threats in a matter of seconds.

Equipped with optical and thermal imaging sights for identifying potential targets and navigating the aircraft in low visibility and nighttime conditions, the new Apache can extend its range and endurance with wing-mounted fuel tanks. Furthermore, it features a fully integrated Defensive Aid Suite to ensure the protection of the aircraft and its crew.

Boeing\'s announcement of the new Version 6.5 AH-64E Apache attack helicopter at the Association of the U.S. Army’s annual conference heralded a significant milestone. Under contract with the U.S. Army, this latest version encompasses software updates and enhancements to the pilot interface. Notable improvements include optimized route and attack planning capabilities, enhanced Link 16 features, and an open-systems architecture to facilitate seamless technology integration in the future.

In parallel, Boeing is collaborating with the Army to integrate the T901, the engine for the Army’s Improved Turbine Engine Program, manufactured by General Electric Aerospace. This engine, designed to replace those in the Apache and UH-60 Black Hawk utility helicopters, as well as future deployment in the Future Attack Reconnaissance Aircraft, has been affected by delays due to pandemic-related issues.

The ITEP engine, alongside drivetrain and tail rotor enhancements, will enable the AH-64E to cover 135 nautical miles to an objective, stay for an hour or more, and return. This represents a significant leap in operational capabilities compared to the current Apache, which can typically only sustain presence at an objective for approximately 30 minutes.

With the rollout of Apache Version 6 helicopters to units beginning in 2021, Boeing is also exploring upgrade possibilities beyond the existing contract. At the Army Aviation Association of America’s annual conference, the company showcased an Apache model featuring an additional wing pylon for expanded onboard weapon options. Furthermore, a concept for a directed-energy capability on one of the pylons was presented, highlighting innovative advancements in the helicopter\'s capabilities.

The Indian Air Force\'s fleet of 22 AH-64E Apache attack helicopters has been further bolstered by an agreement signed in 2020 for the acquisition of six additional Apache helicopters for the Indian Army. The AH-64E remains at the forefront of advanced multi-mission helicopters, incorporating the latest technological enhancements and upholding its reputation as the premier attack helicopter worldwide. Its comprehensive array of capabilities, including enhanced thrust and lift, joint digital operability, improved survivability, and cognitive decision-aiding, positions it as the unparalleled combat helicopter capable of addressing a broad spectrum of mission requirements.

To meet global demand, Tata Boeing Aerospace Limited (TBAL), a joint venture between Boeing and Tata Advanced Systems Ltd. (TASL), has been instrumental in producing AH-64 Apache fuselages. Since 2018, TBAL’s advanced facility in Hyderabad has been delivering AH-64 Apache fuselages, and it is positioned to become the exclusive global producer of AH-64 fuselages, with 90% of parts sourced from Indian suppliers.
