The LCAC or Landing Craft Air Cushion has forever altered our amphibious assault capabilities. The conventional landing craft that preceded it could not reach many shorelines and left Marines struggling in water with 70 pound packs. The LCAC has proven to be an invaluable tool for both military and humanitarian efforts and can access more than 80% of the world's coastlines. This remarkable vehicle has given the Navy many new capabilities and the ability to continue to project power from the sea.
