Saturn MLV
The Saturn Modified Launch Vehicle programme proposed a number of post-Apollo Saturn V derived concepts, intended to create uprated intermediate and heavy launch vehicles based on Saturn V hardware. Saturn MLV features upgraded F-1A engines, stretched tanks for the S-IC and S-II, and upgraded HG-3 engines for both upper stages.
Saturn V INT-20 uses the S-IC and S-IVB, skipping the S-II altogether and optionally reducing the number of first stage engines to compensate for the lower overall mass. INT-21 uses the S-IC and S-II second stage with no S-IVB upper stage. A similar design launched Skylab, given that the orbital workshop was a converted S-IVB stage.
Saturn V-B/C/D concepts are a stage and a half designs, similar to Atlas. The first stage consists of five F-1 engines, of which four are jettisoned leaving the single sustainer engine to carry the payload into orbit. S-IVB is added to the V-C for achieving higher orbits and an optional Centaur upper stage for deep space missions. The V-D is essentially a fully upgraded Saturn V with the addition of 4 large SRBs. Truly a bonkers rocket.
Various post-Apollo optimised and stretched tankage is available in the BDB Extras folder, as well as a patch for the S-IC engine mounting plate to allow fitting fewer than 4 engines. Experimentation is encouraged!
