"Vincennes" was commissioned in 1985, and saw service in the Pacific before being dispatched to the Persian Gulf in 1988 in support of Operation Earnest Will during the Iran–Iraq War. Operating in this capacity the cruiser shot down Iran Air Flight 655 over the Persian Gulf, killing 290 passengers and sparking an international incident between Iran and the United States. Following the cessation of hostilities, "Vincennes" returned to the Pacific Fleet where she remained for the rest of her active career.
