Aircraft carriers can be seen all over the world. They are quite visible and need to be well protected among a battle group to operate. At the other end of the spectrum, a modern submarine is nearly undetectable and can stay somewhere incognito for a long time.
There is a question about launching aircraft from submarines, but the related answers mention past projects in the aftermath of WW2, and nothing about contemporary technology.

I'm interested in a view of the current state of launching aircraft from submarines.
Does anything prevent aircraft to be launched and recovered using submarines platform today?
What is the current state of deployment of such technology around the world?
