The Navy is in the process of reviving its "brown-water" heritage in order to counter the rise of asymmetric threats and contribute to the Long War. Soon, the Littoral Combat Ship will make its way into the Navy, as well as new riverine assets and possibly the X-craft or the new, slick, carbon-fiber-hulled Stiletto. These fast-moving ships and innovative boat designs will build upon the Navy's long-standing legacy in full-spectrum maritime operations.
