CH-47J Chinook

The Boeing CH‑47J Chinook is the Japanese‑specific variant of the iconic twin‑engine, tandem‑rotor heavy‑lift helicopter first flown in 1962 as the CH‑47A. Developed by Boeing (originally Vertol), the Chinook series has served the U.S. Army and allied forces for more than six decades. Japan’s Ground Self‑Defense Force adopted the CH‑47J in 1978, later upgrading to the CH‑47J‑LR standard with modern avionics, a glass cockpit, and enhanced payload capacity. Powered by two GE T55‑702B turboshaft engines, the aircraft can lift up to 12 metric tons externally or transport 55 troops internally, while cruising at 150 knots and reaching a service ceiling of 20,000 feet. Its distinctive tandem‑rotor configuration eliminates the need for a tail rotor, providing superior lift efficiency and maneuverability in confined environments. The CH‑47J has proved indispensable in disaster relief, humanitarian aid, and tactical air‑mobile missions throughout the Asia‑Pacific region, showcasing the adaptability of the Chinook platform. Its longevity and continuous upgrades underscore the helicopter’s pivotal role in modern military logistics and its enduring influence on heavy‑lift aviation worldwide. The type also serves as a basis for joint training with U.S. forces, and recent retrofits include health‑monitoring systems and upgraded communication suites to meet next‑generation mission requirements.
