Upon the outbreak of the Yom Kippur War, Seahorse got underway on less than 24-hours notice on 25 October 1973, deploying to the Eastern Mediterranean Sea with US naval and air forces monitoring the conflict and ensuring freedom of passage. From 16 August through 25 September 1975, Seahorse operated in company with USS Nimitz (CVN-68) and USS South Carolina (CGN-37) as part of Navy Nuclear Task Group 75. In early 1976, Seahorse again deployed to the North Atlantic for ninety consecutive days underway. On 3 November 1976, she entered the Mediterranean on a cruise which lasted until 11 May 1977. Throughout 1978–79, Seahorse underwent nuclear refueling, overhaul, and systems update in the hands of the Charleston Naval Shipyard. In 1980, Seahorse deployed to the North Atlantic, Norwegian Sea, and Mediterranean Sea on a five-month cruise. In July 1981, she participated in a major Second Fleet exercise that ranged from the North Atlantic to the Caribbean Sea. Seahorse sailed for the Indian Ocean in October 1981, returning to Charleston in April 1982, after a 46,000-mile, 181-day deployment that circumnavigated the globe, and touched five of the modern Seven Seas, and all four oceans. The remainder of 1982, she deployed to the North Atlantic, conducting Deep Submergence Rescue Vehicle (DSRV) operations, and participated in the joint US-Canadian Maritime Combined Operational Training (MARCOT) 82 antisubmarine warfare exercise. Seahorse began 1985 underway above the Arctic Circle, and spent August through October of that year deployed in the North Atlantic. In July, 1986, she again deployed to the Arctic, and surfaced through the ice at the North Pole. Seahorse completed her second transit of the Panama Canal in early 1987, en route to Puget Sound Naval Shipyard, Bremerton, Washington for overhaul; she was in shipyard hands from February 1987 through March 1989. In May 1989 she completed her third transit of the Panama Canal, returning to her homeport of Charleston. From March through June 1990 Seahorse again deployed to Arctic waters and the North Pole. In 1991, Seahorse was awarded a second Meritorious Unit Commendation for operations that included under ice operations, another surfacing through the ice at the North Pole, and noteworthy operations in the North Atlantic and Mediterranean Sea. In 1993, at the midpoint of another Mediterranean deployment, Seahorse won her second Battle
