The CH-47J/JA is a medium-transport helicopter for the Japan Ground Self-Defense Force (JGSDF), and the Japan Air Self-Defense Force (JASDF). The differences between the CH-47J and the CH-47D are the engine, rotor brake and avionics, for use for general transportation, SAR and disaster activity like U.S. forces. The CH-47JA, introduced in 1993, is a long-range version of the CH-47J, fitted with an enlarged fuel tank, an AAQ-16 FLIR in a turret under the nose, and a partial glass cockpit. Both versions are built under license in Japan by Kawasaki Heavy Industries, who produced 61 aircraft by April 2001.
The Japan Defense Agency ordered 54 aircraft of which 39 were for the JGSDF and 15 were for the JASDF. Boeing supplied flyable aircraft, to which Kawasaki added full avionics, interior, and final paint. The CH-47J model Chinook (N7425H) made its first flight in January 1986, and it was sent to Kawasaki in April. Boeing began delivering five CH-47J kits in September 1985 for assembly at Kawasaki. Kawasaki continued to make improvements as needed, and in 2017, they reached the milestone of delivering a combined total of 100 units to the Japan Ground Self-Defense Force and Japan Air Self-Defense Force.
The Boeing CH-47 Chinook is an American twin-engined, tandem rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later known as Boeing Rotorcraft Systems). The CH-47 is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of modern-day Washington state. Its prototype model, the CH-47A, was deployed as a U.S. Army’s transport helicopter in 1962, and its performance has since been upgraded with the introduction of successive new models, the CH-47B and CH-47C. The military version of the helicopter has been subject to numerous export sales from nations across the world, typically using it as heavy-lift rotorcraft in a military context.
