I'm wavering on this one. I go with the core stage, and the core stage has some commonalities. New engine, true,but the basic dimensions are essentially the same as the R-7 Blok A. I didn't count an RD-180-engined Atlas 3 as anew family despite its new propulsion system, and I didn't consider the TR-201-powered Delta second stageas a different stage family from the AJ-10-118 powered versions. So I'm leaning towards keeping the Soyuz-2-1V launchesin my 'R-7' family table.
Good point about Atlas III. That may be the proper analogy. In addition, Soyuz 2-1v, like Atlas III, still uses the same launch pads (with modifications) as the previous variants.

Quote from: edkyle99 on 12/22/2013 06:35 pmI'm looking at this as a new rocket, since it uses a new first stage and first stage propulsion system. It surely isn't an R-7. It is "Soyuz" only in the same sense that "Atlas 5" claims a link to the original "Atlas", despite using a completely different booster stage in place of the part that was originally called "Atlas". - Ed KyleI'm wavering on this one.

Similar to the Atlas family including the Atlas III and the Thor family also including the Deltas up to version III, i am also leaning to classify it within the R-7 family.

This may be a long shot, but does anyone here have the launch time line for tomorrow's launch? How many burns will the Volga upper stage do?

I know that TsSKB-Progress has been negotiating with SSTL and the Koreans for launching commercial payloads on the S-2.1v - who will then provide the launch services? (Starsem? New company?)

Three payloads: Two SKRL-756 calibration spheres and the Aist satellite as the main payload? Just working out how to represent the launch (usually the rocket and the primary payload).
