'JASDF personnel from Naha, Japan, disembark from a JASDF CH-47 helicopter at Kadena.' Thus the squadron within the Rescue Wing is probably Naha Kyunantai. For some reason this young Chinook was withdrawn from use and scrapped in 2002. It was delivered in 1989. In the peculiar JASDF serial system, the first digit is the last digit of the year of delivery, the second digit is for the aircraft type (the F-4 Phantom also has 7) and the third digit is for a role/aircraft class, in this case 4 for helicopters.
