Do Aircraft carriers have any Aero design onsiderations?
 

Specifically, is any gain in laminar airflow across the flight deck to assist/enhance take-off and landings a consideration in the ships overall design?

I would suspect not since a carrier deck, as well as an LHA has tiedowns, stays, catapault tracks, elevators and sometimes aircraft, ropes cables buildings.

Might be a bit of laminar over the bow, at speed, into a stiff wind, but it wouldn't exist very far.

On US carriers the deck is extremely flat in the takeoff portion IMO.
My thinking a carrier in many ways might operate as an inverted flat bottom car with a front splitter, optimizing smooth/proper air flow for aircraft on the deck, but my question centers around, is that intentional?
Maybe not, since the "sky Jump" carrier decks would have I suspect lousy aero features,

Looks Flat to me.

Compared to what? They have the advantage over land based runways in that they can orient into the wind.

Boat-tail a carrier?

"My thinking a carrier in many ways might operate as an inverted flat bottom car with a front splitter, optimizing smooth/proper air flow for aircraft on the deck, but my question centers around, is that intentional?"

Seems air with a non-splitter early style blunt bow would be likely cascading a lot of turbulence over the bow and would generate very unpredictable and large air currents onto the deck just as a plane was lifting off.

Your test case would be those carriers with an ski-jump ramp.

Apparently, the reason these are used is they can delete the catapult system.

Also, the comparison is to a car's underbody, which is a plenum.

No it's not, because it appears rather obvious the benefits of the ski jump solution outweigh the negatives of beneficial smooth airflow that a ski jump does not allow, and that is mainly when not able to afford or incorporate a catapult system.

The car analogy I was using here has nothing to do with a plenum, it centered mainly on the latest designs on the carrier deck acting like a car's front splitter which calms under chassis air flow leading to other attributes that apply little to a carrier, like DF, drag etc,

Whatever....
