USS Hershel "Woody" Williams (ESB-4) is a Lewis B. Puller-class expeditionary mobile base (ESB), currently in service with the United States Navy. The ship is also a sub-variant of the Montford Point-class expeditionary transfer dock (ESD). The ESDs are operated by the Navy's Military Sealift Command with predominantly civilian crews, while the ESBs, owing to the nature of their operations, have been commissioned and commanded directly by the U.S. Navy. The ship was named in honor of Hershel W. "Woody" Williams in an announcement by then-Secretary of the Navy Ray Mabus, on 14 January 2016. Williams was a Marine who was awarded the Medal of Honor in the Battle of Iwo Jima, during World War II.
