They are longer ranged in anti-ship mode than in anti-air - it
has to be that way, the height it has in AA mode at maximum range
is available as energy to get out farther at the surface. SM2 ER
should be good to 90 sea miles.

That doesn't mean targeting and sensors work that way, the world
being curved and all.

(I'm not sure that these are usefully smaller than harpoon - the
diameter of both is 13.5")

A quick search reveals the following:

Harpoon weight of 1145 lbs Max Speed = 530mph

SM2 weight of 2980 lbs(don't know if this includes booster) Max Speed =
1900mph

Now the Harpoon carries a much larger warhead but the SM2 is heavier and
impacts at a much higher speed. Is it reasonable to make a SWAG that a
Standard SM2 will inflict as much or more damage?

After all, speed kills....
