I confess, at least 50% of my reason for posting this is to be an unapologetic shill for my own plane.
That being said, here's the Hart Armaments "Kailach", a plane with an internal missile rack.

Has anyone else experimented with this concept? Feel free to link your own designs!
I dont have an idea how i could make it work
Yes. This funny-looking box of a plane. The trick is high detach force on the pylons to kick the missile out of the bay before it moves forward.
