Motive was laid down on 14 April 1942 by the General Engineering & Dry Dock Company of Alameda, California; launched on 17 August 1942; and commissioned on 17 April 1943. After shakedown, Motive got underway from San Francisco, California, 5 June 1943 and arrived Dutch Harbor, Unalaska Island, on 14 June. She made one round trip back to Alameda, California as a convoy escort from 26 June to 14 August Motive then operated continuously in the Aleutian Islands for the next four months as convoy escort and anti-submarine patrol. On 13 October, while anchored in Massacre Bay, Attu Island, Motive was attacked by about ten Japanese aircraft making a fast high level attack. She received six near misses from 100-pound bombs but no damage, and drove the enemy planes off with gunfire.
Motive sailed for Pearl Harbor on 1 December, and on 22 January 1944 sailed for Kwajalein, where she conducted minesweeping and antisubmarine operations until 14 February, when she departed for Pearl Harbor and repairs in California. Returning to Pearl Harbor on 22 May, she joined TF 52 for the capture of Saipan, whose assault began on 15 June. Motive, in TG 52.9, the demonstration group, participated in the dawn feint on the beaches north of Tanapag town, while the actual landings were taking place at Charan Kanoa. On patrol as antisubmarine and screening vessel, Motive fired on Japanese aircraft on 16, 17, and 18 June, and was strafed by a Zero on 17 June, receiving a number of hits which were quickly repaired.
Motive left Saipan for Eniwetok on 24 June, returning 9 July. She then conducted sweeping operations off the east coast of Saipan and undertook antisubmarine patrols. From 24 July until November Motive served as a convoy escort, antisubmarine patrol and screening ship, operating out of Saipan, Eniwetok, Guam, and Ulithi. While at Ulithi with a convoy on 20 November, Motive observed the torpedoing of Mississinewa (AO-59) which broke into flame. The convoy got underway for Guam without further incident.
Although she remained inactive, Motive was reclassified as MSF-102 on 7 February 1955. She was struck from the Naval Vessel Register on 1 December 1966 and destroyed as a target by the Pacific Fleet in April 1968.
