The first stage was an increased diameter version of the S-IC. The second stage was an increased diameter S-II stage. Both of these stages had eight engines, as opposed to the standard five. The third stage was a stretched S-IVB stage, which retained its original diameter and engine. NASA announced on September 7, 1961 that the government-owned Michoud Ordnance Plant near New Orleans, LA, would be the site for fabrication and assembly of the Saturn first stages as well as larger vehicles in the Saturn program. Finalists were two government-owned plants in St. Louis and New Orleans. The height of the factory roof at Michoud meant that an 8 x F-1 engined launch vehicle (Saturn C-8, Nova class) could not be built; 4 or 5 engines would have to be the maximum. This decision ended consideration of a Nova class launch vehicle for Direct Ascent to the Moon or as heavy-lift derivatives for Earth Orbit Rendezvous. Ultimately, the Lunar Orbit Rendezvous ("LOR") concept approved in 1962 rendered the C-8 obsolete, and the smaller Saturn C-5 was developed instead under the designation "Saturn V", as the LOR spacecraft was within its payload capacity. The Saturn C-8 configuration was never taken further than the design process, as it was too large and costly.
