Lift to low Earth orbit:

Space shuttle & Delta IV: ~23 metric tons

CaLV: >100 metric tons to orbit

[Nowhere]

Hmmm...exactly what ">100" means is unknown as of yet, I presume? Anyway, it means this booster will be more powerfull than Energia configurations that flew and possibly more powerfull than Saturn V...
PS. I wonder if/when it'll achieve the LEO capability of most powerfull Energia configuration...

[Dr Mordrid]

I've read reports that its LEO capacity could be as much as 120 metric tons, making it one formidable SOB. This is one I'd go to see launched.
