Upscaling towards Saturn V performance?

At some point, clustering the existing CBCs gets unwieldy and
hits an upper limit in performance; Boeing proposes a new and
larger CBC for a next-generation heavy lifter that achieves
and exceeds Saturn V class performance.

I'm pretty sure that the next Atlas will not rival or exceed the Saturn
V as
that would require a 500% boost in payload capacity.

Boeing does not make the Atlas. Damon is describing a
descendent of the Delta IV common core booster which is
larger than the current version. Clusters of that
larger core could conceivably achieve Saturn V
performance, especially considering that configurations
using not just 3, but 5 or more common cores have been
proposed.

Still that does not change the fact that the Delta-IV-H has only 1/5th the
load capacity of the Saturn V and will therefore need a five-vold increase
in capacitity to match the old Saturn V. I simply don't see them doing that
in the next generation (if ever).

So maybe we should build Shuttle Cs if there is no way for the Deltas to do it.

The load capacity of a Shuttle C still wouldn't match the Saturn V (I think;
I reckon it could lift 75 tons in LEO). But the biggest problem is that it
would be difficult for for it to include both the CEV, moon lander and
needed rocket/fuel module in one package. Also, if something goes wrong, the
CEV and the crew are history as they are located on the side of the fuel
tank, not on top of it.

They could be launched in tandem, there are two launch pads capable of handling
the Shuttle. Launch the Lunar Lander in one and the CEV on another. These two
parts dock in low Earth obit and you have a 150 ton vehicle.
