Significant technological advances have been made in estimating tidal current and water levels using numerical models as well as in estimating vessel maneuverability using shiptow simulators. Benefits in applying these technologies to planning an amphibious assault include 1 minimizing operational risk by testing the feasibility of the navigability of an area 2 determining the capacity and timing of that operation 3 defining the optimal axes-of-assault that best ensures navigational safety and 4 developing a training platform for executing a particular plan.This report summarizes a proof-of-concept study for demonstrating the application of these technologies to allow commanders to determine the feasibility of surface amphibious operations and their use in a virtual amphibious assault near the Port of Anchorage, Alaska. This site was chosen because the environmental conditions at this location dictate that only a narrow window of time is available for conducting surface ship-to-shore operations.The vessel used in the virtual assault is the 1646-class Landing Craft Utility LCU. The U.S. Navy USN provided two experienced craftmasters for piloting the LCU. Their assessment was that the simulator provided a realistic environment and the handling of the virtual LCU closely resembled that of a standard displacement landing craft.
