Valkryien Skies 2 is in BETA. It's generally stable and you can play with it, but we haven't even reached 1% of our full potential. Valkyrien Skies 2 is the next generation of Valkyrien Skies, with support for 1.16.5 and 1.18.2 Forge/Fabric. Valkyrien Skies 2 no longer comes with blocks and gameplay elements built in. You will need an add-on like Eureka.
You need Kotlin for Forge! For 1.18, you need the latest version of Forge!
It is highly recommended to install all 3 mods, otherwise you won't have the blocks and items you need to actually build ships!
Valkyrien Skies aims to be the Minecraft ships mod everybody's always wanted. That means it includes interactive blocks, custom collision for walking on ships, mod compatibility, and more.
Truthfully a lot of the problems other ship mods have claimed to be as impossible and impractical are indeed quite solvable, and Valkyrien Skies remains as proof of that. A fully integrated custom control system is in the works, but for now the mod is stable enough to be used as a physics sandbox built into Minecraft.
There's are also the following addon mods available for Valkyrien Skies:
