store.steampowered.com
Forever Skies is a first-person post-apocalyptic survival game. Return to Earth, ravaged by an ecological disaster. Fly, upgrade and customize your mobile high-tech airship base. Scavenge resources to survive, face dangers on the surface and hunt for viral pathogens to cure a mysterious illness.

Didn’t buy it yet, will most likely wait a few days to watch a few videos but had it wishlisted since it seemed interesting. Seems to be a mix between Raft, Worlds Adrift and Subnautica.
