Falcon 9 is an active partically reusable launch system. It is developed and formerly operated by SpaceX. Falcon 9 has been build in 3 different version: Falcon 9 v1.0, v1.1, v1.2 FT. There are also subvariants called blocks and SpaceX has stated that block 5 will be final subvariant of Falcon 9 v1.2 FT. Falcon 9 v1.0, v1.1 and v1.2 FT has been used to launch Dragon spacecraft to International Space Station through Commercial Resupply Service program. Falcon 9 v1.2 FT will be also used to launch Crew Dragon to International Space Station through Commercial Crew Development program. The vehicle operates out of Space Launch Complex 40 at Cape Canaveral Air Force Station, Launch Complex 39A at Kennedy Space Centre and Space Launch Complex 4-E at Vandenberg Air Force Base.
I recommend turning on "Advanced tweakables" in KSP settings.
To download each variant of Falcon 9, go to the "Files" section.
