Underwater demolition
From Wikipedia, the free encyclopedia
Underwater demolition refers to the deliberate destruction or neutralization of man-made or natural underwater obstacles, both for military and civilian purposes.
Shortly after the American Civil War, Brevet Maj. Gen. John G. Foster, a West Point trained engineer, became one of the first acknowledged experts in underwater demolition. In 1869, he wrote a definitive treatise on the topic and became widely recognized as the authority on underwater demolition. Many of his theories and techniques were still in practice during the Spanish-American War and World War I.
In June 1943, Draper L. Kauffman organized the first U.S. Navy Demolition Teams. The original purpose of these teams was to map and record conditions in amphibious landing zones and to demolish obstacles in water which would prevent vehicles from landing during invasions.[1] Underwater demolition specialists may still be referred to as underwater demolition teams.
