Concise (AMc-140), a coastal mineseeper, reclassified as a minesweeper, AM-163, on 21 February 1942,  was laid down on 15 June 1942 at Portland, Oregon, by the Willamette Iron & Steel Corp.; launched on 6 February 1943; and commissioned on 25 April 1944, Lt. Henry J. Ullmann, Jr., USNR, in command.

Sailing from San Francisco, Calif., on 3 July 1944 for Pearl Harbor, Territory of Hawaii, Concise arrived on 13 July for training. She swept mines at French Frigate Shoals from 6 to 16 August, then sailed to Eniwetok, in the Marshalls, arriving on 28 September. Assigned to convoy escort duty until 11 August 1945, Concise arrived off Okinawa, in the Rykyus, on 30 August.

On 8 September 1945, she sailed to clear mines from Japanese waters in protection of occupation shipping, sweeping off Wakayama, Osaka, and Nagoya until 20 November. Concise returned to San Francisco, Calif., on 16 December 1945 and was placed out of commission in reserve on 31 May 1946 at San Diego, California.

She was reclassified MSF-163 (minesweeper, steel hull) on 7 February 1955, and stricken subsequently. Ex-Concise was scrapped in 1959.
