On 16 August 1968, after her fitting-out at Boston, O'Callahan departed for her homeport of San Diego, California. En route she called at Norfolk, Virginia; Charleston, South Carolina; and Fort Lauderdale, Florida. She stood out of San Diego on 1 October for 25 days of electronics and weapons systems tests off the Pacific Northwest, then commenced shakedown on 4 November. After at-sea training operations off the Hawaiian Islands from 6 through 17 February 1969, she entered the Long Beach Naval Shipyard on 4 March for post-shakedown availability through mid-May. She then conducted further training operations out of San Diego in preparation for her first deployment to the Western Pacific.

O'Callahan served until 31 May 1989, when she was decommissioned and leased to Pakistan. However, following Pakistan's refusal to halt its nuclear weapons program, the lease was cancelled in 1994. She was returned to United States custody at Singapore on 19 August 1994 and stricken from the Navy Register the same day. On 9 September she was transferred to the Maritime Administration and sold to Trusha Investments Pte. Ltd, c/o Jacques Pierot, Jr. & Sons, Inc., of New York City for over $600,000. She was then towed to Hong Kong and scrapped.
