USS Simpson (FFG-56)

USS Simpson (FFG-56) was an Oliver Hazard Perry-class guided-missile frigate of the United States Navy, commissioned on 21 September 1985. Named after Rear Admiral Rodger W. Simpson, the ship played a significant role in operations such as Operation Earnest Will during the Iran-Iraq War, protecting oil tankers in the Persian Gulf. Notably, USS Simpson is remembered as the last U.S. Navy ship to have sunk an enemy vessel in combat, when she destroyed an Iranian gunboat during Operation Praying Mantis in 1988. After nearly three decades of service, USS Simpson was decommissioned on 29 September 2015.
