On 20 June 1989, only a few days following the change of command from Commander Terry W. Moore to Commander Bruce P. McClure, "John L. Hall" got underway with for a transit of the Atlantic Ocean to participate in Anti-Submarine Warfare Operations (Operation ROJO) in the north and east Atlantic Ocean. Operation ROJO lasted 41 days. While underway, the ships were under the command of Destroyer Squadron 32. The operation was a great success as both ships held contact on two Soviet submarines for an extended period of time.
