Service history

Inter-War Period

After shakedown training in the Caribbean and post-shakedown availability in the Boston Navy Yard, Sims joined the Atlantic Squadron at Norfolk, Virginia on 2 August 1940. The destroyer operated with the Neutrality Patrol in Caribbean and South Atlantic waters. In November–December 1940, Sims patrolled off Martinique. On 28 May 1941, the ship arrived at Newport, Rhode Island, and began operating from there. She sailed for Iceland on 28 July with an American task force. In August, the destroyer patrolled the approaches to Iceland. In September–October, the ship made two North Atlantic patrols. Sims had been attached to Destroyer Squadron 2 (DesRon 2) since she began making Neutrality Patrols.
