The Supreme Allied Commander Atlantic (SACLANT) was one of two supreme commanders of the North Atlantic Treaty Organisation (NATO), the other being the Supreme Allied Commander Europe (SACEUR). The SACLANT led Allied Command Atlantic, based at Norfolk, Virginia. The entire command was routinely referred to as 'SACLANT'. In 1981 SACLANT's wartime task was listed as being to provide for the security of the area by guarding sea lanes to deny their use to an enemy and to safeguard them for the reinforcement and resupply of NATO Europe with personnel and materiel.
