USS Inaugural

In 1968, Inaugural was relocated to St. Louis to serve as a floating museum. The vessel was designated as a National Historic Landmark on January 14, 1986, as one of two surviving Admirable-class minesweepers used in the Pacific during World War II.

In August 1993, during flooding of the Mississippi River, Inaugural broke loose from its moorings at the Gateway Arch. The ship suffered a breach in its hull, took on water, and rolled on its side.
