Background: During the 1950s the U.S. Army Ordnance Corps sponsored a product-improved version of the DUKW called the XM147 “Super DUCK”, several versions were manufactured by GMC for evaluation by the Army and Marine Corps. The Super DUCKs were tested at Aberdeen Proving Ground (APG), MD from 1953 through 1957 but the project was ultimately cancelled in favor of the Transportation Corps LARC-5. The author came across a surviving Super Duck (serial #351) in October 1996 languishing in an Eastern Shore, MD field. Despite the rust, it was relatively damage free, complete and the following day was spent loading it on a truck for delivery to Aberdeen, MD.
