330-PSA-142-62 (USN 711080):  The “Airoll” proved itself in the sand.  On reaching soft terrain, the wheels automatically became stationary, with the pneumatic tires serving as cleats or crippers in the manner of tracked vehicles.  The report on the testing of the 19,000 pound test platform noted the Airoll system can “achieve greater travel efficiency on most soil conditions than conventional wheeled or tracked vehicles. Master Caption:  This multi-wheeled, rubber-tired behemoth is the test platform for a new concept in off-the-road transport known as the “Airoll.”   Developed for the U.S. Navy under a contract with the Office of Naval Research, the Airoll is the first successful mating of the track and wheel.  It was originally conceived by the Ingersoll, Kalamazoo Division of the Borg-Warner Corporation.  The free-rolling tires mounted on an endless chain can take the vehicle easily over ordinary impassable terrain, such as deep mud, heavy snow, and watery swamplands.  The Marine Corps has ordered eight one-half ton amphibious versions to be used as personnel/weapons carriers.  Photograph released June 18, 1962.  (10/6/2015).
