The DUKW (GMC type nomenclature, colloquially known as Duck) is a six-wheel-drive amphibious modification of the 2+1⁄2-ton CCKW trucks used by the U.S. military during World War II and the Korean War.
Designed by a partnership under military auspices of Sparkman & Stephens and General Motors Corporation (GMC), the DUKW was used for the transportation of goods and troops over land and water. Excelling at approaching and crossing beaches in amphibious warfare attacks, it was intended only to last long enough to meet the demands of combat. Surviving DUKWs have since found popularity as tourist craft in marine environments.[5]
