New Unit Idea : Star Whale (Interplanetary Aircraft Carrier)

Then Plan behind the Star Whale is to have mobile drop of point for air crafts to attack another planet.
The Carrier itself should be relatively fragile (maybe 1.5 times the HP of an SSX) but have large carrying capacity for conventional and orbital Crafts.
It has to go in "landing mode" (hovering close to the planets surface) to load it with conventional Air crafts and can be load with orbital fighters while in orbit.
Once it's loaded it can fly from one planet to the next. The travel speed between planets should be longer than most other crafts, to give the enemy enough time to spot it.
When the Star Whale reaches the orbit over an planet it can disgorge all it's cargo at once and from orbit, so you can start attacking the enemies ground forces with your planes without have to land first.

I'm not deep enough in the Unit resource cost to give an adequate estimation how much this should cost.

Star Whale

I just want to call a unit in the orbital layer a Star Whale.
