All U.S. Navy aircraft carriers are now chlorofluorocarbon (CFC)-free. Naval Sea Systems Command (NAVSEA)’s Shipboard Ozone Depleting Substances (ODS) Elimination Program marked a major environmental milestone April 2 with the elimination of the final ozone depleting CFC refrigerants aboard the aircraft carrier USS Carl Vinson (CVN 70). “NAVSEA is eliminating these CFC refrigerants because they deplete the earth’s protective ozone layer which screens out potentially harmful radiation from the sun,” said Gregory Toms, NAVSEA ODS elimination program manager. NAVSEA strives to be a good steward of the environment while building the future Navy and sustaining the current fleet. Currently Carl Vinson is nearing completion of a Refueling Complex Overhaul.
