Exactly. For that matter, the "Mercury 7" and the "New Nine" agree too; the Redstone/Atlas/Titan II's used for the Mercury and Gemini missions were ICBMs (edit: actually, was the Redstone technically an ICBM? I think as weapons they were short-range actually), originally meant to deliver nuclear bombs to Russia. (They were modified in several ways before being used for human flight of course, mostly for reliability). The Redstone in particular was a direct descendant of the V-2.
