The fuel capacity of the CH-47D Chinook is 1,080 gallons
The Boeing CH-47 Chinook is a tandem-rotor helicopter that was initially developed by the American rotorcraft company, Vertol. It is now manufactured by Boeing Defense, Space & Security. The CH-47D is an upgraded version of the Chinook, which was the result of a June 1976 contract for a modernized version of the helicopter. The CH-47D has a fuel capacity of 1,080 gallons (4,088 litres).
The Chinook is a heavy-lift helicopter, second only to the Sikorsky CH-53 in terms of weight-lifting capacity in the Western world. The Chinook was originally designed by Vertol, which began work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. The CH-47D has a maximum gross weight of 54,000 pounds (24,494 kg) and a payload lift capacity of up to 27,000 pounds (12,565 kg).
The CH-47D can carry a wide variety of internal payloads, including vehicles, artillery pieces, 33 to 44 troops, or 24 litters plus two medical attendants. It can also carry up to 26,000 pounds of external cargo. The Chinook has three cargo hooks: a centre (main) hook and two additional hooks fore and aft of the main hook. The minimum crew required to fly this helicopter is two pilots (excluding staff aviators, where a senior instructor pilot must have continuous and full access to the flight controls) and a flight engineer.
The CH-47D played a crucial role during Desert Storm, often serving as the only mode of transportation capable of rapidly shifting large numbers of personnel, equipment, and supplies over vast distances. The cargo capacity and speed provided by the CH-47D gave US commanders and logisticians an unparalleled advantage on the battlefield. The CH-47D has also been continuously upgraded and improved, with new features such as in-flight refuelling capability and terrain-following/terrain-avoidance radar.

The CH-47JA model has improved fuel tanks
The CH-47 Chinook is a tandem-rotor helicopter developed by Vertol and manufactured by Boeing Defense, Space & Security. It is a heavy-lift helicopter that can carry a wide variety of internal payloads, including vehicles, artillery, troops, or medical equipment. The Chinook has been used by the U.S. Army and 19 other countries worldwide.
One of the variants of the Chinook is the CH-47JA, introduced in 1993 as a long-range version of the CH-47J. The CH-47JA is fitted with improved fuel tanks, an enlarged fuel tank, and a partial glass cockpit. This variant is built under license in Japan by Kawasaki Heavy Industries, who produced 61 aircraft by April 2001.
The CH-47JA's improved fuel tanks allow it to fly longer distances and stay in the air for extended periods. This increased fuel capacity enhances the helicopter's range and endurance, making it suitable for various missions, including search and rescue, disaster relief, and transportation.
The CH-47JA's enlarged fuel tank also contributes to its long-range capabilities. With a larger fuel capacity, the helicopter can cover greater distances without refuelling, making it ideal for operations where fuel stops may be limited or inaccessible.
The partial glass cockpit in the CH-47JA model offers improved visibility and advanced avionics. This enhances the pilot's situational awareness and makes it easier to navigate during long-range missions. The combination of improved fuel tanks and a glass cockpit makes the CH-47JA a versatile and capable helicopter for a range of operations.

The MH-47G variant has redesigned fuel tanks
The MH-47G variant has a fuel capacity of 4,088 liters (1,080 gallons) and is powered by twin Honeywell T55-GA-714A engines with 4,777 horsepower each. The aircraft has a mission radius of up to 165 nautical miles (190 miles/306 kilometers) and a speed of 170 knots (302 kilometers/188 miles per hour). It has an operational altitude of 20,000 feet (6,096 meters), which is higher than other helicopters in its class. The Chinook Block II production will strengthen the manufacturing base, guaranteeing timely support to both the production line and soldiers in the field.
The MH-47G variant can be equipped with mounted machine guns, rotary miniguns, and missile systems, depending on its mission. It has a maximum gross weight of 54,000 pounds (24,494 kilograms) and a payload lift capacity of up to 27,000 pounds (12,565 kilograms). The Chinook is a multi-mission aircraft used by the U.S. Army and 19 other countries worldwide. The Chinook program supports more than 20,000 jobs and 360 suppliers in 40 states.
The MH-47G variant was first delivered to the service in 2014, with additional orders placed in subsequent years. The latest deal brings the army's future MH-47G Block II fleet to 46 aircraft. Boeing's Cargo Programs VP and Program Manager, Heather McBryan, has praised the MH-47G Block II as a "proven workhorse for special operations." The MH-47G is part of the Department of Defense's initiative to enhance the airborne capabilities of the Special Operations Aviation Command (USASOAC).

The CH-47SD variant has extended-range fuel tanks
The CH-47 Chinook is a heavy-lift helicopter manufactured by Boeing Defense, Space & Security. It is a multi-mission aircraft used by the U.S. Army and 19 other countries. The CH-47SD variant, also known as the "Super D", is a modified version of the CH-47D with extended-range fuel tanks and a higher payload-carrying capacity. This variant is used by the Republic of Singapore Air Force, the Hellenic Army, and the Republic of China Army.
The CH-47SD is an upgraded version of the CH-47 Chinook, which was first introduced in the 1950s. The Chinook is known for its ability to operate in a wide range of terrains, including mountainous positions, due to its rear ramp access not being restricted by tail rotor clearance. This design allows the helicopter to execute pinnacle landing capabilities. The CH-47SD variant further enhances the Chinook's capabilities with its extended-range fuel tanks, enabling it to fly even farther.
The CH-47 Chinook has undergone various upgrades and modifications over the years to meet the evolving needs of military operations. The CH-47SD variant, with its extended-range fuel tanks, is an example of how the Chinook has been adapted to increase its range and payload capacity. This modification is particularly useful for long-distance missions and transporting heavy equipment or large numbers of personnel.
The Chinook's fuel capacity and range are crucial factors in its operational capabilities. The CH-47SD's extended-range fuel tanks provide an increased fuel capacity, allowing the helicopter to cover greater distances without refuelling. This extended range enhances the Chinook's versatility and effectiveness in various missions, especially in special operations and transport roles.
The CH-47SD variant's extended-range fuel tanks contribute to the Chinook's overall capability and performance. By increasing the fuel capacity, this modification allows the helicopter to stay airborne for longer periods and cover larger distances. This enhanced range enables the Chinook to operate in remote areas and support military operations that require extended flight times or transportation of heavy payloads over long distances.
