When the Stennis was released, we were able to also select the out of 4 parking spots on the ramp to spawn on from the mission editor. They removed it in an update right after they announced the super carrier for the first time. Also, since then, static aircraft placed on a moving carrier don't show, if I browse for them with F12 all I see is some partial model dragging across the ocean floor.
I'm referring with the Stennis, not the Carl Vinson.
And the Kuznetsov used to have space for 4 aircraft plus helicopters had their own spawn points, but they reduced it down to 3 aircraft spots.
If 3 aircraft occupy the Kuznetsov, helicopters now must wait for aircraft to take off to be able to spawn.
So the announcement of the super carrier has just degraded the current carriers we have, not sure if it's just bugs...or free carriers got nerfed to entice people to buy the super carrier mod.
