    Dictionary of American Naval Fighting Ships History: Alarm (AM-140) was laid down on 8 June 1942 at Tampa, Fla., by the Tampa Shipbuilding Co.; launched on December 1942; sponsored by Mrs. M. A. Lynch; and completed on 5 August 1943. On the latter day, she was transferred to the Soviet Navy under the lend-lease program and served them as T-113.
