Does anyone know what they intended to use the Saturn V-4X(U) for? Was this intended for the lifting of modules for the space station?

Boeing study, 1968. Four core vehicles from Saturn V-25(S) study lashed together to obtain million-pound payload using existing hardware. First stage consisted of 4 Saturn IC's stretched 498 inches with 6.64 million pounds propellant and 5 F-1 engines; second stage 4 Saturn II standard length stages with 5 J-2 engines

Realtively vague concept for a heavy lifter, easier to field than an all-new booster of the "Post Saturn" variety. By the late '60's the whole idea was moot, as NASA was beginning to shut down and didn't see a need for anything much bigger than Titan III-capability.

How did they intend to lift components for the 12-person space station, 50-person space base, and then the 400-person space hotel before they went the modular route with space shuttle-carried modules?

Saturn V. But those plans were dead by 1969. 7/31/68, in fact.

Do you know what configuration of Saturn V would have been used to launch the space station modules? July 31, 1968 was the date in which the decision was made by NASA to not build additional Saturn V rockets?

The INT-21, the two stage basic variant. S-IC + S-II. This was the most straightforward Saturn V derivative they had on hand. Adding boosters or strechtching stages is nice... when your production line is open. After it closed the only way of grabbing some Saturn V for a space station is killing lunar missions.

Have a look at this, from NASA NTRS.

Thanks Archibald. I have been looking for this artwork and I was confident that NASA had this art posted somewhere. :D
