First pic is of the C-3 vehicle as proposed in this study-- 30 foot diameter, 2 F-1 engines peripherally mounted, 4 J-2 second stage, LR-115 (became RL-10) or single J-2 third stage 18 feet 4 inches in diameter...

Third pic is the "orbital launch vehicle" concept using integral tanks (common bulkhead tanks). This "OLV" was to be assembled in orbit from 5 launches of components on the C-3 vehicle, and then launched toward the moon from LEO (low earth orbit). Note the Apollo payload of the time was the direct descent model where the Apollo capsule would land on the moon on top of a lunar descent stage and be launched back to Earth using a lunar ascent stage under the Apollo capsule...

The fourth pic is the "OLV" using stages consisting of seperate tanks. Common bulkhead tanks were thought to be possible but seperate propellant tanks were also considered as a fallback position should difficulties in making them work crop up.

The fifth pic is a sideview diagram of the four J-2 engined second stage of the C-3 launcher.

Some of these pics I've put into paint and 'fixed' some of the poor image quality by going over faded lines and/or adding larger text or dimensions to make them more readable. Enjoy! OL JR
