USS Emory S. Land AS-39 (1979)
Expeditionary Mobile Base (ESB) This is a whole new class of vessels, that are adapted from oil tankers. They are cut down to feature large open well deck areas to handle amphibious forces, including Landing Craft Air-Cushioned (LCAC), and in the case of the Lewis B. Puller below, have a flight deck built on top to handle up to 4 helicopters, with a hangar and other facilities built over the bows. The whole offers an inexpensive alternative to the landing ship docks above, which, in low intensity use, could base the same amphibious and air units (or warsearcher staff have the whole concept wrong).
