CH-47D Chinook

The CH‑47D Chinook, developed by Boeing Rotorcraft Systems, is an iconic tandem‑rotor heavy‑lift helicopter that entered service with the United States Army in 1971. Evolving from the original CH‑47A prototype of the early 1960s, the D model incorporated a more powerful twin‑engine configuration, upgraded transmission, and a strengthened airframe that enabled higher payloads and improved reliability in demanding environments. With a maximum take‑off weight of roughly 22,000 pounds, the Chinook can transport up to 55 troops, 24,000 pounds of cargo, or externally sling loads as heavy as 26,000 pounds. Its dual rotors rotate in opposite directions, eliminating the need for a tail rotor and providing exceptional lift, stability, and maneuverability in confined or high‑altitude zones. Throughout its decades‑long career the CH‑47D has been deployed in combat, humanitarian relief, and disaster‑response missions worldwide, proving indispensable in Vietnam, the Persian Gulf, Afghanistan, and numerous relief operations after earthquakes and hurricanes. The aircraft’s versatility, robust design, and proven performance have cemented its role as a workhorse of modern military aviation and set a benchmark for heavy‑lift rotorcraft. Continued upgrades keep the CH‑47D relevant into the 21st century, ensuring its presence in future operations.
