Boeing CH-47 Chinook

The Boeing CH‑47 Chinook is a twin‑engine, tandem‑rotor heavy‑lift helicopter that has served the United States Army and allied forces since its first flight in 1961. Developed by Boeing Vertol, later Boeing Rotorcraft Systems, the Chinook entered service in 1962 during the Vietnam War, where its ability to transport troops, artillery and supplies quickly earned it a reputation for reliability and versatility. Over six decades, the airframe has undergone continuous upgrades, including more powerful T55‑GM engines, modern digital flight controls, and advanced avionics suites, culminating in the latest CH‑47F model with a glass cockpit, health‑monitoring systems and increased payload capacity of up to 12,700 kg. Its distinctive tandem‑rotor configuration eliminates the need for a tail rotor, providing superior lift efficiency and maneuverability in confined environments. The Chinook’s speed—up to 315 km/h—and range exceeding 2,600 km enable rapid deployment of forces and humanitarian aid in disaster zones worldwide. Its longevity and adaptability have made it a benchmark in heavy‑lift rotary‑wing design, influencing subsequent helicopters and cementing its status as an indispensable asset in military and civilian aviation. Today, more than 1,200 Chinooks are in service across 30 nations, underscoring its enduring global impact.
