By the late 1960's, Cutter 37 become the last United States vessel still in commission that had seen action during the Pearl Harbor attack on December 7, 1941. From that time on, she was often referred to as “The Last Survivor of Pearl Harbor.”
During the Vietnam War in 1969-1970, USCG Cutter 37 participated in “Operation Market Time” in the South China Sea. As a unit of Coast Guard Squadron III, Cutter 37 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, Cutter 37 was reassigned from the 12th Coast Guard District in San Francisco to the 5th Coast Guard District in Virginia. From 1973 to 1977, Cutter 37 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, Cutter 37 had the distinction of completing the Coast Guard's last ocean weather patrol when she closed out of the Ocean Weather Station Hotel.
