Disposition of the CH-47B Helicopters

          In service to the United States Army

 

 

             As of December 2002, we had generally a good idea what became of most of the B model Chinooks. Many of the details surrounding the demise of most of the known lost aircraft has remained a mystery. There are no surviving U.S. Army B models.
