Design

The 38-foot DUKW was designed for the U.S. Army to carry men and supplies from offshore ships and across a beach. The term "DUKW" is a manufacturer's code designation. It translates to "D" for 1942, "U" for utility vehicle, "K" for front-wheel drive, and "W" for two rear-drive axles. The nickname "Duck" grew out of this code and the amphibious capability of the craft.

The DUKWs acquired from the U.S. Army were constructed of sheet steel. The following modifications were made by the Coast Guard: installation of an aluminum alloy cover over the driver's area and extending aft over the forward part of the cargo space; a self-bailing cockpit in the after part of the cargo space; a walkway along each side of the cover; towing bitts and tow rail; and navigational lights. In 1948 the Coast Guard constructed additional units at the Coast Guard Yard, Curtis Bay, MD. These had aluminum bodies and incorporated the experience learned from using the Army model.

DUKWs were most useful in flood relief. However, the craft suffered from high maintenance casts, rapid deterioration due to salt water, and a lack of watertight subdivisions. All of the vehicles had been disposed of by 30 September 1970.
