The new Delta IV-H and (possible) Delta V-H ELV's still fall far short of
the performance of the Saturn V moon rocket. At the moment they have about
a
quarter of the latter's performance. I'm beginning to wonder if it's
even
feasible (both technically and economically) to even upscale these things
to
Saturn V performance. Wouldn't it be easier jjust to start from scratch
and
design another 100 ton LEO booster with a 10 meter fairing? Anyway, if it
is
at all possible to scale these things to Saturn V performance it will take
at least another 3 generations.

Economical? Not on your Aunt Nelly! Economics means there's a product
people are willing to purchase and that means there has to be a market. No
market. Fifty tonnes will be fine for the next 15-20 years.
