It is a self-tracker, having it there gives it a pretty fair sweep of the compass. it isn’t like they’ll need the centerline on that ship.
Sure, the issue I’d think is more having it getting pummeled by waves breaking over the bow in rough seas.
USN carriers (except the Lexingtons) had open bows with gun mounts up until the Forrestals. The Midways and many Essexes ended up being retrofitted with enclosed “hurricane” bows because the benefits provided by having defensive guns out there wasn’t worth the downsides. Which included damage to the mounts resulting from heavy weather (which, on a couple of the Essexes, also resulted in the forward flight desk collapsing)
