NASSCO/General Dynamics
National Steel and Shipbuilding Company (NASSCO), a division of General Dynamics, has pitched some significant modifications to the U.S. Navy’s Expeditionary Sea Bases (ESB), which is an existing highly flexible class of ship based on a modified oil tanker that supports the forward deployment of various forces. The proposed enhancements were conceptualized to address emerging U.S. Navy requirements and include the notable addition of an unmanned underwater vehicle (UUV) bay.
