Studied with the Saturn A-1 in 1959, the Saturn A-2 was deemed more powerful than the Saturn I rocket, consisting of a S-IB first stage, which actually flew on the Saturn IB, a second stage which contains four S-3 engines that flew on the Jupiter IRBM and a Centaur high-energy liquid-fueled third stage.{{Cite web|url=http://www.astronautix.com/s/saturna-2.html|archive-url=https://web.archive.org/web/20161228044720/http://astronautix.com/s/saturna-2.html|url-status=dead|archive-date=December 28, 2016|title=Saturn A-2|website=www.astronautix.com}}
