The Apache helicopter uses jet fuel, specifically JP8
The Apache helicopter, also known as the Boeing AH-64 Apache, is a highly advanced attack helicopter used by the U.S. Army and other nations. When discussing the fuel consumption of the Apache helicopter, it is important to note that it uses jet fuel, specifically JP8. This type of fuel is commonly used in military aircraft and is designed for aircraft powered by gas-turbine engines.
JP8 jet fuel is a kerosene-based fuel that contains a range of hydrocarbons. It is known for its ability to power the Apache's two General Electric gas turbine engines, each rated at 1890 shaft horsepower. This fuel enables the Apache to achieve a maximum gross weight of 17,650 pounds, allowing for a cruise airspeed of 145 miles per hour and a flight endurance of over three hours.
The Apache helicopter's fuel efficiency has been a key area of focus for improvement. For example, the AH-64E version of the Apache, introduced in 2013, boasts improved fuel efficiency, increasing its time on station from 2.5 to 3 hours and even up to 3.5 hours in certain cases. This enhancement was particularly notable during combat deployments, as it allowed for longer periods of attack and surprised Taliban forces, according to reports.
The Apache can be equipped with external fuel tanks to extend its range during missions. It has a combat radius of approximately 150 kilometers without external fuel tanks. However, with a single external 230-gallon fuel tank installed, its combat radius increases to approximately 300 kilometers. This flexibility in fuel configuration allows the Apache to adapt to different mission requirements and ensures its effectiveness in various operational scenarios.
In summary, the Apache helicopter's use of JP8 jet fuel, coupled with its powerful engines and advanced systems, contributes to its exceptional performance and reputation as one of the world's most formidable attack helicopters. The ongoing improvements in fuel efficiency and range demonstrate the continuous efforts to optimize the capabilities of this versatile and lethal aircraft.

The AH-64E Apache has better fuel efficiency than previous models
The AH-64E Apache is an upgraded variant of the AH-64 Apache series, developed by Boeing. It is a state-of-the-art attack helicopter, widely used for advanced reconnaissance, precision strikes, and close air support missions. The AH-64E Apache has improved fuel efficiency compared to previous models, enabling it to stay in operation for longer periods.
The AH-64E features twin T700-GE-701D engines that deliver increased power output and superior fuel efficiency. This enhanced engine technology, coupled with advanced avionics, results in improved manoeuvrability and extended mission capabilities. The helicopter can sustain operations for over three hours without refuelling, a significant improvement over its predecessors.
The fuel efficiency of the AH-64E Apache translates into longer mission durations and increased time on station. While previous Apache models could remain on station for 2.5 to 3 hours, the AH-64E extends this duration to 3 to 3.5 hours. This increased time on station caught Taliban forces off guard during combat deployments in Afghanistan, as the AH-64E attacked sooner and for longer periods.
The AH-64E Apache's improved fuel efficiency is also attributed to its advanced connectivity, which includes the Joint Tactical Information Distribution System (JTIDS) and Link 16. These systems enable real-time data sharing and cooperative targeting with other assets, optimising fuel usage during joint-force operations.
Additionally, the AH-64E Apache can be configured with external fuel tanks to further extend its range and mission time. It has mounting points on its stub-wing pylons, allowing for the installation of one or more 230-gallon external fuel tanks. This flexibility in fuel tank configuration provides the AH-64E with greater endurance and adaptability to meet the demands of various mission profiles.

The Apache can be configured with external fuel tanks to extend its range
The Boeing AH-64 Apache is a highly advanced, twin-turboshaft attack helicopter. It is designed to be quick-reacting and highly stable, with the ability to fight during the day, night, and in adverse weather conditions. The Apache has undergone several upgrades since its inception, with the AH-64E being the most modern configuration.
The Apache's range can be extended through the use of external fuel tanks. The standard combat radius of the AH-64 is approximately 150 kilometers. However, when configured with a single external 230-gallon fuel tank, the combat radius extends to approximately 300 kilometers. This configuration is particularly useful for attack missions, where greater endurance is required.
For ferrying or self-deployment missions, the Apache can be outfitted with up to four 230-gallon external fuel tanks, further increasing its range. This flexibility in fuel tank configuration allows the Apache to adapt to different mission requirements, ensuring it can reach more distant targets or operate for extended periods.
The Apache's fuel system has been designed with crashworthiness in mind, incorporating features to minimize the risk of fuel-related fires or explosions in the event of a crash. This includes the integration of crashworthy landing gear, seats, and a fuel system that meets the stringent MIL-STD-1290 standard.
The Apache's fuel efficiency has also been a focus of ongoing improvements. For example, the AH-64E variant offers better fuel efficiency than its predecessor, increasing its time on station from 2.5 to 3 hours, and even up to 3.5 hours in certain conditions. This extended endurance allows for longer mission durations and improved operational capabilities.
In summary, the Apache helicopter's range can be significantly extended through the use of external fuel tanks, providing it with greater flexibility and endurance for various mission profiles. This, coupled with ongoing improvements in fuel efficiency and range, ensures that the Apache remains a highly capable and versatile attack helicopter.
