I get in, uh "discussions" with pro-navy people a lot about ICBMs. Admittedly I get most of my anti-surface navy bias from War Nerd and the Millenium Exercise...and Argentina sinking UK ships in the Falklands... but still. Is it true that the basic cruise supersonic missle that hugs the surface and then plops up and drops from above is basically undefendable by surface ships? It's guidance that is 1970s tech at best. Other Navy guys said their ships would start going into evasive maneuvers and no missle at hypersonic speeds could hit them. With JDAM tech that seems pretty specious.
