John I think that treaty would allows us to carry nukes to LEO, ja?. I
agree the nuclear upper stages are a great idea, but atmospheric stages
would be a huge headache from an engineering point of view. I don't even
see how it could be practically done, even if the treaty hadn't outlawed it.
But no matter: we can still use them to get hauling once we have the stuff
I can make a stronger case: if we needed to get a wacky high amount of delta
Vee, the Orion might be the only really practical way to git R done. A
chemical rocket would require (I think) at least five stages to get up to
the 30 km/sec we discussed before, but eight stages would be more efficient.
Then of course the vehicle is crazy complicated, and would likely need
extensive assembly in LEO.
