USS Lewis B. Puller (ESB-3), (formerly USNS Lewis B. Puller (T-ESB-3), and (T-MLP-3/T-AFSB-1) prior to that) is the first purposely-built expeditionary mobile base vessel (previously classified as a mobile landing platform, and then as an afloat forward staging base) for the United States Navy, and the second ship to be named for Chesty Puller. She is the lead ship of her class of expeditionary mobile bases and is also a sub-variant of the Montford Point-class of expeditionary transfer docks. Lewis B. Puller replaced USS Ponce (AFSB(I)-15) with the U.S. Fifth Fleet in the Persian Gulf in Fall 2017.
