On December 31, 1965, the Army base was formally decommissioned and the installation became a Coast Guard base. At that point, most of the World War II-era buildings on the island's southern tip were still standing. The Coast Guard consolidated its operations at Governors Island, making the island the Coast Guard's largest installation. The island was used as a base of operations for the Atlantic Area Command and its regional Third District command. By 1985, the island had a population of 4,000 personnel and 1,000 family members. It was also homeport for U.S. Coast Guard cutters, including USCGC "Gallatin" (WHEC-721), USCGC "Morgenthau" (WHEC-722), and USCGC "Dallas" (WHEC-716).
