USS Batfish is a Balao-class submarine, known primarily for the remarkable feat of sinking three Imperial Japanese Navy submarines in a 76-hour period, in February 1945. Since 1973, USS Batfish has served as an unlikely museum ship hauled up on shire at the Muskogee War Memorial Park in Muskogee, OK, near the confluence of the Arkansas River, Grand River, and Verdigris Rivers. Now with the rivers at historic flood levels, the World War II era submarine is afloat on the flood water, as volunteers scramble to keep the old sub from sinking or being overwhelmed by the swirling torrents.
