All sixteen ships survived the war, but were decommissioned shortly afterwards in favor of the larger, faster . Kennebec, Merrimack, Kankakee, Mattaponi, Monongahela, Tappahannock, and Neches were recommissioned for the U.S. Navy after World War II. Mattaponi and Tappahanock were reactivated four times, serving until 1970. Chiwawa (now Lee A. Tregurtha) is still in commercial service on the Great Lakes. Neshanic (now American Victory) was sold for scrap and towed away to Turkey in 2018.
