The Coast Guard acquired five of the Navy ’s '' Cyclone '' - class patrol ship beginning on October 1 , 2004 . The Coast Guard initiated the action because of its aging fleet , increased operational hours following the terrorist attack on 9/11 , delays in delivery of the converted 123-foot patrol boats , and the continued deployment of 110-foot cutters to the Persian Gulf , all of which created a gap in patrol boat availability . The transfer immediately lessened shortfalls in patrol boat hours . The Navy and Coast Guard signed an agreement in August 2004 , that allowed five ships to be under the operational command of the Coast Guard . Two of the five ships were scheduled to be returned to the Navy in 2008 ; the remainder in 2011
