As indicated by bolding a certain portion of a quote, I was referring to the claim that "Western navies never felt the need for anti-ship weapons", which is clearly incorrect in view of the list of dedicated anti-ship weapons. Besides, there are plenty of general purpose weapons that do quite nicely in anti-ship role e.g. Maverick, SLAM.
As for 'something fundamentally new', I did inform you about the Franco-German ANS (Anti-Navire Supersonique). A follow on to the abortive ANS is the ANNG/ANF (Anti-Navire Novelle Generation / Anti-Navire Future), later called ASURA, which is based on the operational ASMP (Air Sol Moyen Portee) nuclear strike missile. It would have Mach 2, 180 km, seaskimming capability. It is direct competition with SCALP cruise missile.

Also , I would not consider e.g. the Norwegian NSM an incremental improvement. It is a new missile, simple to operate, very sneaky and stealthy, so much tso the the USN will likely adopt it in large numbers. And it will be morphed in a multi-role VLS and encapsulated submarine launch compatible version for the US called Joint Strike Missile (JSM) that will feature an option for ground strike and a two-way communications line and improved range over NSM's 185km to 280 km. Further, just because LRASM-A isn't supersonic doesn't mean it is not in certain ways revolutionary e.g. in terms of operational autonomy.
