context_page_description: USS Cocopa (ATF-101) was an Abnaki-class fleet ocean tug that served on active duty with the U.S. Navy from 1944 to 1978, seeing action in World War II, the Korean War and the Vietnam War. After thirty-four years of service, she was sold to the Mexican Navy, where she was still in service as of 2009.
context_section_description: During the Vietnam War, Cocopa saw service in five campaigns: Advisory (1963), Vietnam Defense (1965), Counteroffensive Phase II (1967), Summer-Fall 1969, and Ceasefire (1972).  In 1965, Cocopa hosted Detachment Charlie of Beach Jumpers Unit One, Team Twelve, operating as the "Yankee Station Special Surveillance Unit". This outfit consisted of one officer and five enlisted men, whose mission was to jam Soviet electronic intelligence trawlers monitoring U.S. operations in the Gulf of Tonkin. Team members utilized random wave jamming with noises (including bagpipe recordings) to counteract Russian SIGINT activities.  Cocopa also assisted in towing, recovery and similar operations throughout her tours in Vietnam.
