The F/A-18E Super Hornet holds 14,400 lbs of fuel internally
The F/A-18E Super Hornet is a strike fighter aircraft capable of air-to-air and air-to-ground/surface missions. It was designed and initially produced by McDonnell Douglas, first flying in 1995, and later by Boeing. The F/A-18E Super Hornet holds 14,400 lbs of fuel internally, and additional fuel can be carried in up to five external fuel tanks. This gives the aircraft a total fuel capacity of 29,000 lbs when fully loaded with internal and external fuel tanks.
The Super Hornet's ability to carry a substantial fuel load is a significant advantage, enabling it to undertake extended missions and providing tactical flexibility. The aircraft's range can be further enhanced through in-flight refuelling, utilising its built-in aerial refuelling system (ARS) or "buddy store" capability. This system allows the Super Hornet to refuel other aircraft, filling a critical tactical airborne tanker role for the Navy.
The Super Hornet's fuel capacity is a notable improvement over its predecessor, the Hornet. The Hornet, while effective, had a limited combat radius due to its smaller fuel capacity. The Super Hornet's enlarged design, with its longer fuselage and larger wings, directly addresses this issue by accommodating more fuel and enhancing its overall performance.
The development of advanced variants, such as the Block III Super Hornet, further extended the aircraft's capabilities. These variants offered features such as conformal fuel tanks (CFT) and enhanced engines, contributing to increased range and service life. The Advanced Super Hornet prototype, self-funded by Boeing and Northrop Grumman, also showcased a reduced frontal radar cross-section and an enclosed weapons pod, demonstrating the continuous pursuit of improved performance and stealth capabilities.
The F/A-18E Super Hornet's fuel capacity is a critical aspect of its design, enabling it to undertake a range of missions and adapt to various tactical scenarios. Its ability to carry substantial fuel loads, both internally and externally, coupled with its refuelling capabilities, ensures that it remains a versatile and valuable asset for military operations.

The Hornet's range can be extended with up to five external fuel tanks
The F/A-18 Hornet is a twin-engine carrier-capable multirole fighter aircraft. The F/A-18 Hornet was redesigned into the larger F/A-18 Super Hornet, which has a larger wing and a longer fuselage to carry more fuel and more powerful engines. The Super Hornet has an internal fuel capacity of 14,400 lbs, and it can also carry additional fuel in up to five external fuel tanks. The external fuel configuration includes a 330 US gal (1,200 L) tank with a hose reel on the centerline and four 480 US gal (1,800 L) tanks, for a total of 29,000 lbs (13,000 kg) of fuel on the aircraft. The Hornet's range can be further extended through in-flight refuelling, and the aircraft can also be configured as an airborne tanker for refuelling other aircraft.
The Hornet's fuel consumption varies depending on its altitude and speed. At low altitudes, the Hornet guzzles gas, while at higher altitudes, it achieves better fuel efficiency. For example, at sea level, the Hornet can go 500 miles before running out of fuel, whereas at 36,000 feet, it can achieve a range of 990 miles. Additionally, flying at supersonic speeds consumes a lot of fuel, especially when at lower altitudes, so a tactic employed by Hornet pilots is to fly at subsonic speeds at lower altitudes to conserve fuel.
The Hornet's range limitations have led to the development of advanced variants, such as the Advanced Super Hornet, which features conformal fuel tanks (CFT) and an enclosed weapons pod (EWP). These modifications aim to increase the aircraft's range and service life while also improving its stealth capabilities. The Advanced Super Hornet underwent flight tests in 2013, and while it was not pursued for production, many of its elements were transferred to the Block III variant.
In conclusion, the F/A-18 Hornet's range can be extended through the use of up to five external fuel tanks, in-flight refuelling, and advanced variants with increased fuel capacity. These options provide tactical advantages and flexibility for the Hornet's mission profiles.

The F18's fuel consumption is higher at low altitudes
The F/A-18 Hornet, also known as the Super Hornet, is a fighter jet designed and initially produced by McDonnell Douglas. It first flew in 1995 and officially entered operational service in 1997. The Super Hornet is capable of carrying out air-to-air and air-to-ground/surface missions and has a maximum speed of Mach 1.8. While the exact fuel capacity of the F/A-18 is not publicly available, we do know that it can be equipped with up to five external fuel tanks in addition to its internal fuel capacity.
The fuel consumption of aircraft like the F/A-18 Hornet is indeed typically higher at lower altitudes. This is due to several factors related to the principles of aerodynamics and engine performance. Firstly, at lower altitudes, the air density is higher compared to higher altitudes. As a result, the aircraft experiences increased drag, requiring more engine thrust to maintain its speed and altitude. This increased thrust requires more fuel, leading to higher fuel consumption.
Additionally, the wings of an aircraft are designed to generate lift, which is essential for keeping the plane in the air. At lower altitudes, the aircraft needs to maintain a certain speed to ensure sufficient airflow over the wings to generate enough lift. If the speed drops too low, the aircraft may experience a stall, where it loses lift and starts descending rapidly. To avoid this, the pilot may need to increase engine thrust, resulting in higher fuel consumption.
Another factor affecting fuel consumption at lower altitudes is the weight of the aircraft. As fuel is consumed during flight, the aircraft becomes lighter. At higher altitudes, this weight reduction can be compensated for by reducing lift and, consequently, drag. However, at lower altitudes, the aircraft may need to adjust its angle of attack (AoA) to maintain lift, which can increase fuel consumption.
It's worth noting that while flying at higher altitudes can offer fuel economy benefits, there are also considerations that limit how high an aircraft can safely fly. For example, at extremely high altitudes, the air pressure becomes very low, requiring the cabin to be pressurised for the comfort and safety of passengers and crew. This pressurisation adds weight to the aircraft, which then requires more lift and thrust, ultimately increasing fuel consumption. Therefore, pilots and flight planners must carefully consider the trade-offs between altitude, fuel efficiency, and other operational constraints when charting a course.
