Real Rockets Mods

[Niallalva]

Does anybody know of any GOOD mods that add real rocket parts from real missions (even missions that never happened like NASA's constellation mission).

There are several parts mods listed as recommendations on the Realism Overhaul thread:

 

[Bornholio]

Raidernick has a lot of US and Soviet rockets probes and other parts for virtually all historical rockets. 

The RO umbrella has all these and more https://github.com/KSP-RO

Real ISRU is getting updates with 2018 research.  Head over to RO/RP0 and see @winged constellation and DRA5 stuff.

As for stockalike it gets a lot more thin but SSTU does a good job of later stuff.
