WHEN amphibious warship USS Wasp (LHD-1) deploys the first time from its new homeport in Japan in late 2017, it’ll ship out with some extras: a squadron of Marine F-35B Lighting II Joint Strike Fighters, three guided-missile destroyers, a Marine general and a Navy admiral. The deployment will be a test for a so-called upgunned Expeditionary Strike Group that will combine a traditional three-ship Amphibious Ready Group (ARG) with a three ship guided-missile destroyer surface action group (SAG), Adm. Scott Swift, commander of the U.S. Pacific Fleet, told US Naval Institute News.
