History
trailing 180 daysAbout this indicator
Big-deck amphibious assault ships (LHA/LHD hulls — each the flagship of an Amphibious Ready Group embarking a ~2,200-strong Marine Expeditionary Unit) in the same Iran-relevant waters, from the weekly USNI Fleet & Marine Tracker. An ARG/MEU afloat gives Washington ground-force options short of invasion; Marines moving to the region are both a signal and another accident surface. Calm normal is zero in theater.
