Reply #2: We need the old heavy lift rocket

[Cobalt-60]

With our fortune squandered by Republicans, we don't have anything like the cash for R and D on a new heavy rocket.
Fortunately we already had the finest heavy lifter the world had ever seen in the Saturn V.

While the tooling for the original F-1 is long gone, we do have the specifications.
And we have flight motors that weren't used.
It is well within the capacity of modern manufacturing techniques and facilities to initate a new production run of these engines.
As far as the rest of it is concerned, we can build better tankage and structural components with modern materials.
The costly installations built aroundthe Saturn are still there. They wouldn't have to be built new.
Modern computers and control are a geological epoch beyond those we had before.
And, if we want to dominate in heavy lift capacity, I offer you another gem from the First Space Age : Sea Dragon.
It was meant to be the ultimate big dumb rocket.
It was optomized to reduce development and deployment costs.
And it was designed to carry the load of 10 Saturn Vs.

While this giant was never built, much proof of concept was done by its designer.
he launched a flock of rockets out the water to prove it could be done.
