Saturn C

Background

The Saturn C series (BDB Sarnus) study oversaw the evolution of a heavy launch vehicle that would eventually become the Saturn V. Only the Saturn C-1 and C-5 variants actually flew, as Saturn I and Saturn V respectively.

Saturn C-2 is a four-stage launch vehicle using the S-I and S-IV stages from Saturn I, and inserting an S-II second stage powered by four J-2 engines (a smaller variant of the five engine S-II used on Saturn V). The launch vehicle is topped by the S-V stage (actually a Centaur C but substituted for a Centaur D here).

Saturn C-3 features a widened (5m KSP Scale) S-IB-2 first stage tank with two F-1 engines, a widened S-II of the same diameter and topped by the S-IV stage. Other considerations included a three engines C3B with a first stage tank widened even further (6.25m KSP Scale) and the C-3N, which features a nuclear NERVA engine in the third stage.

Saturn C-4 consists of three stages: an S-IB-4 first stage, essentially the same size as the C-3 but with four F-1 engines, the S-II second stage and a single J-2 powered S-IVB third stage.

The C-5 adds a fifth F-1 engine to the widened first stage tank of the C-3B and a fifth J-2 to the S-II stage, finalising the configuration that would become the Saturn V launch vehicle.

Saturn C-8 is a larger than Saturn V "Nova Class" rocket designed for Apollo direct ascent lunar missions. Almost but not quite entirely identical to the post-Apollo Nova C8 concept for manned Mars missions, the C-8 features eight F-1 engines on a widened (7.6m KSP Scale) S-IC-8 first stage, eight J-2 engines on the S-II-8 second stage and a stretched S-IVB stage with a single J-2 engine.
