No, they are not carried on the FFG, nor have they ever been. And, since the Navy removed the Mk-13 launchers from all of the Perry FFGs, they no longer carry any type of missiles except what can be fired from the embarked helicopter.
I reckon that, if they did eventually carry ASROCs, they would be able to extend the frigate's ASW reach, but that's what they have the helicopter for anyway.
