Gunderson also builds welded steel LCM-3 landing craft, locally described as tank lighters. Each 85-foot hull uses twin General Motors diesel engines and can carry a thirty-ton Sherman tank or construction machinery. The barge-like form is deliberately simple but robust enough for exposed Pacific waters. A popular Portland exhibition lets civilians board the craft, connecting home-front production with the amphibious logistics it supports overseas.
