USCGC Acacia (WAGL-200) was originally built for service by the U.S. Army as a mine planter shortly after World War I and later transferred to the U.S. Lighthouse Service, which became part of the U.S. Coast Guard in 1939; when transferred the ship was redesignated as a Speedwell-class buoy tender. She was sunk in 1942 by a German U-boat.
