Beach Jumpers were U.S. Navy special warfare units organized during World War II by Lieutenant Douglas Fairbanks, Jr.. They specialized in deception and psychological warfare. The units were active from 1943–1946 and 1951–1972.
Lieutenant Douglas Fairbanks, Jr., the Hollywood actor and naval officer, was assigned as a United States liaison officer to British Admiral Lord Louis Mountbatten, who was British Chief of Combined Operations, which included British Commando operations. Fairbanks not only observed the training, planning, and execution of the Commando's raiding parties, diversions, and deception operations, but he trained with the unit and participated in several cross channel harassment raids. During these raids he developed a deep appreciation for the military art of deception.
When he returned to the U.S., Fairbanks presented his idea for a unit of men trained to conduct tactical cover, diversionary and deception missions to Admiral Ernest J. King, Commander-in-Chief, U. S. Fleet and Chief of Naval Operations. Inspired by the success of the British Commando in using sonic deception on raids against the Nazis and Fairbanks' concept of operations, King issued a secret letter on 5 March 1943 charging the Vice Chief of Naval Operations with the responsibility to recruit 180 officers and 300 enlisted men for the Beach Jumper program. Admiral H. Kent Hewitt Commander of Amphibious Forces and all U.S. Naval Forces in Northwest African waters and the Western Mediterranean, was put in charge.
Beach Jumper volunteers had to meet four general requirements: no seasickness, experience with small boat handling, enough electrical knowledge to fix a home radio, and basic knowledge of celestial navigation. The announcement further stated that, "The Navy is requesting volunteers for prolonged, hazardous, distant duty for a secret project."
