Potential enemies don't have a monopoly on anti-ship missiles:
Japan has become the latest F-35 user to order the Norwegian "Joint Strike Missile" (JSM). Kongsberg has been developing JSM since 2011 as an air-to-surface weapon that is not only stealthy but also designed to be launched from the internal bomb bay of the F-35 (where two can be carried). The half-ton JSM, with a 250 kilometer range, is based on the existing Kongsberg NSM (Naval Strike Missile).
That's just one missile. But with so many countries buying the F-35, countries like China, Russia, and Iran will find their ships at risk just leaving port (if not while sitting in port).
