A major portion of U.S. military combat power and sustainment will arrive in theater via commercial shipping and military sealift vessels of varying drafts.  In order to optimize force closure timelines and sustain the force vessels must unload as close to the point of debarkation as possible. The MRSD will provide an organic and intermodal transportable dredging capability to enable joint forces access and maneuver through areas previously inaccessible due to shallow shoreline gradients.
