USS Sentinel (AMCU-39) was a LCI(L)-351-class large landing craft of the United States Navy, later converted to an AMCU-7-class coastal minesweeper.

Following installation of Army-type radio equipment, LCI(L)-1052 remained in the area ferrying passengers and carrying mail around Eniwetok Island until 12 October.

LCI(L)-1052 remained at Tacloban, Leyte Gulf, until 22 July, performing there the same services she had rendered at Ulithi, until hostilities ended.

After arriving at San Francisco on 18 February, the landing craft proceeded to Astoria, Oregon, where she reported to the 19th Fleet and was decommissioned in September 1946.

On 7 March 1952, LCI(L)-1052 was named and reclassified as USS Sentinel (AMCU-39), and a contract for her conversion into a minesweeper was placed with the Puget Sound Naval Shipyard, Bremerton, Washington.
