The Shadow, the Beach Jumpers had a "mysterious power to cloud men’s minds," though it came from the study and development of tactics, rather than "traveling in the Orient." Beach Jumper volunteers were recruited for "prolonged, hazardous, distant duty for a secret project." Their identities and activities were very highly classified, since the slightest leak of information could ruin even brilliant deceptions. Many Beach Jumpers went to their graves without ever revealing, even to their wives and children, what they had done in the Navy.
The U.S. Navy had active Beach Jumper units from 1943-1946 and 1951-1972.
Their early basic mission was "To assist and support the operating forces in the conduct of Tactical Cover and Deception in Naval Warfare." To accomplish it, they learned to simulate very large amphibious landings with very limited forces. Using specialized deception equipment, a few dozen Beach Jumpers could make the enemy believe they were a 70,000-man amphibious landing force, when in fact that force would be elsewhere, usually a great distance away.
The Beach Jumpers were formed in
World War IIafter Lieutenant Douglas Fairbanks, Jr., the Hollywood actor turned naval officer, was assigned to duty with British Admiral Lord Louis Mountbatten’s Commandoin England. 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. It was during these raids that he gained a true appreciation for the military art of deception.
When he returned to the U.S., he presented his idea for a unit of men trained to conduct tactical cover, diversionary and deception missions. Inspired by the success of the British Commando in using sonic deception on raids against the Nazis and Fairbanks' concept of operations, Admiral
Ernest J. King, Commander-in-Chief, U. S. Fleet, and Chief of Naval Operations, issued a secret letter on 5 March 1943 charging the Vice Chief of Naval Operationswith the recruitment of 180 officers and 300 enlisted men for the Beach Jumper program.
The recruits had to meet four general requirements: (1) no
seasickness, (2) experience in small boat handling, (3) enough electrical knowledge to fix a home radio, and (4) at least fundamental knowledge of celestial navigation. The announcement further stated that "The Navy is requesting volunteers for prolonged, hazardous, distant duty for a secret project."
had been attached. The latter could be towed behind the boats to enhance their radar cross-section. Later, the Beach Jumpers acquired various jamming transmitters such as the APT-2 (Carpet); APQ-2 (Rug); AN/APT-3 (Mandrel); AN/SPT-4; AM-14/APT; AM-18/APT; and AN/SPT-1 (DINA).
The Beach Jumpers got their name because of their ability to quickly hit the beach and confuse the enemy with harassment and deception operations. During a high level conference, someone stated that the purpose of the Beach Jumpers’ work was "to scare the be-jesus out of the enemy." The term "BJ factor" was used thereafter in their planning, and is said to have inspired the cover name Beach Jumpers.
Beach Jumpers saw much action in WWII. Their first operation was in Operation HUSKY, the
Allied invasion of Sicily. On the night of 10 July 1943, Beach Jumper Unit ONE was ordered to conduct a diversion off Cape San Marco, 100 miles west of the HUSKY landing area. The first attempt was recalled due to hazardous seas. On D+1, the weather was better and the operation began at 2200 hours. At 3,000 yards off shore, three of the ASRs prepared their heaters, one ASR proceeded a thousand yards ahead and began to lay smoke. As the sound boats prepared to make their run parallel to the beach, a searchlight from Cape San Marco illuminated the area, accompanied by small arms and artillery fire. At 0230 the sound boats were ordered to secure their heaters and approach the beach, which they did, firing guns and rockets. All boats retired on a course back to their home port at Pantelleria, Sicily.
To keep the Germans’ attention, the unit was ordered to conduct another operation on the night of 12 July 1943, using all available craft. This time the shore batteries were completely alerted. The Germans were convinced that a landing was about to take place. Salvos of six inch and smaller guns were thrown at the boats. The operation was a success and no casualties were sustained.
Operation HUSKY accomplished complete surprise due to the uncertainty created in the minds of some German Commanders by the diversions and deception operations. BJU-1 was responsible for an entire German Reserve Division being held in place, as the German Command was unsure where the actual landing would take place.
Beach Jumpers continued to work successfully in the
Mediterraneanthrough the summer of 1944. Beach Jumper operations in the Pacific were less rewarding, but at least one diversion proved effective, allowing the 34th Regimental Combat team and the 38th and 11th Airborne Divisions to land with little or no opposition.
Shortly after the end of WWII, all Beach Jumper Units were deactivated.
They were reactivated in 1951, in spite of the objections of those who questioned the worth of a deception unit in these more sophisticated times. A Beach Jumper unit was given a chance to prove its worth when an important training exercise was being planned. The Beach Jumpers knew that Fleet communications from the Force Commander to ships at sea were relayed through radio Washington. Pretending to be the Force Commander, they sent an official message, via Radio Washington, ordering every ship’s Commanding Officer to report aboard the flagship the next morning to discuss terminating the exercise. The next morning at least half of the ships’ Commanding officers were aboard the flagship in a state of mounting confusion and anger. There were no more doubts about the worth of the Beach Jumper program.
Through the late 1950s and into the early 1960s as the
Cold Warevolved into the " CounterinsurgencyEra," Beach Jumper expertise in the area of manipulative and imitative deception and electronic warfare(EW) was employed in revolutionary new ways, both during scheduled fleet exercises and on actual operations. Additionally, they acquired a new secondary mission: "To plan and execute Psychological Operationsin support of commands to which assigned."
Several Beach Jumper teams were active in the
Vietnam War, responsible for tactical deception and for employing psychological operations (PSYOPS), which was also their unclassified cover activity. They operated from several naval platforms including the USS Iwo Jima (LPH-2)and USS Tripoli (LPH-10). Their primary mission was to assist and support the operating forces in the conduct of Tactical Cover and Deception. They conducted monitoring, tape preparation and Soviet Signal Intelligence SIGINTtrawler jamming missions from destroyers. Some of the men became paratroopers, possibly to add credibility to the Beach Jumper cover name.
Other Beach Jumpers operated under the cover name "Yankee Station Special Surveillance Unit," aboard fleet tugs such as the USS Cocopa (ATF-101). Their mission was to deceive and jam Soviet Signal Intelligence (SIGINT) and Electronics Intelligence (
ELINT) trawlers that were monitoring U.S. Naval operations in the Gulf of Tonkin. This group conducted counter SIGINT trawler activities which included random jamming with noises that even included bagpipe recordings.
The Beach Jumper name was retired in 1972, and the Beach Jumper mission was assigned to Fleet Composite Operational Readiness Group ONE (FLTCORGRU ONE). In 1986, Fleet Tactical Deception Group Pacific (FLTDECGRUPAC) and Fleet Tactical Deception Group Atlantic (FLTDECGRULANT) were formed, with the mission of "Assisting Commanders in the planning and conduct of tactical military deception operations."
Former Beach Jumpers are eligible to join the U.S. Navy Beach Jumpers Association and to be Associate Members of the UDT-SEAL Association.
