The Boxer is quite able to handle anything these pirates or their friends can throw. If she is equipped like her sister ship, The USS Kearsarge, she has twin Ma Dueces, 25MM manual controlled guns on each side, rolling frame surface to air missle launchers, sea sparrow surface to air missle launchers, and I believe three 20 Mike Mike Sea Wizs (Phalanx)that can be used against air and surface targets.
