Saturn 1B Uprated Saturn I SA-200 series

Mission Profile

The Saturn IB (Saturn 1B, Uprated Saturn I) was a two-stage American launch vehicle in the Saturn family, the workhorse of the Apollo programme for Earth-orbital missions. Standing 68.1 m tall with a 6.6 m diameter and a liftoff mass of 590 tonnes, it generated 7,100 kN of liftoff thrust and could deliver 18,600 kg to low Earth orbit. First flying in February 1966 under the Apollo programme, the Saturn IB launched the first crewed Apollo flight (Apollo 7), the Apollo-Soyuz Test Project, and all three crewed Skylab missions, serving as NASA's medium-lift launcher throughout the late 1960s and 1970s.
