Several thousand tons taking off of the moon?
How would you do that?

On earth more than 90 percent of a launcher is fuel. Granted moons
gravity would allow less.

What do you think, how much fuel youd needed if it would be possible
to get such a monstrum from the ground to orbit in one peace.
Were would you get this fuel from?

Oh, now I see. Hope your bombs would not blast the cycler craft apart.
But I dont see that in the first starting phase were the inertia
holds the craft back while it gets all of the bombs blasting waves .
