2The General Motors Corporation DUKW was without a doubt the most successful amphibious military vehicle ever constructed. This is due in large part to the enormous amount of scientific and engineering talent that was devoted to the project. Included in the design team were America's Cup winner Rod Stephens, adventurer and environmentalist Dennis Puleston, and scientist and engineer Palmer C. Putnam. The DUKW was so successful and so widely used that Gen. Dwight Eisenhower described it as one of the most valuable pieces of equipment produced by the United States during the war. This book chronicles the development and use of these vehicles from concept to combat in WWII and Korea. Through dozens of archival photos, many never before published, as well as detailed photographs of some of the finest existent examples of surviving vehicles, these iconic armored fighting vehicles are explored, and their history is explained.
