A few comments:
The Navy doesn't "always look" for submarines- this costs money. Fuel for ASW aircraft, sonobouys, etc. In peacetime, it just isn't done. That being said, the Navy did get rid of the S-3 Viking (mistake, IMO) from the carrier air wings. The air wings are a shadow of their old selves.
The Osprey doesn't damage the non skid on the decks of ships any more than the Harrier does- and they take off and land vertically on the deck with little to no damage.
