During the Vietnam War in 1969-1970, USCGC Taney participated in “Operation Market Time” in the South China Sea. As a unit of Coast Guard Squadron III, Taney interdicted illegal arms and supplies along the coast of South Vietnam, fired over 3,400 rounds of 5”/38 ammunition in support of American and South Vietnamese troops, and provided medical assistance to more than 5,000 Vietnamese civilians.
In February 1972, Taney was reassigned from the 12th Coast Guard District in San Francisco to the 5th Coast Guard District in Virginia. From 1973 to 1977, Taney carried out the Ocean Weather Patrol at Weather Station Hotel, which is roughly 200 miles off the coast of New Jersey. She also participated in “hurricane hunting” after receiving a special Doppler weather radar installation atop her pilot house. In September 1977, Taney had the distinction of completing the Coast Guard's last ocean weather patrol when she closed out of the Ocean Weather Station Hotel.
