Below are some renders of a number of 3D CAD models of launch vehicles. Most are currently extremely basic… accurate to size and shape, but lacking details. The intent on most of them is to use them for diagramming purposes… but the possibility exists of using them as the basis for 1/288 scale display models. To that end they would probably be designed for simplicity and low parts count rather than complexity and the ability to display them with stages separate.
As can be seen, a lot of them make the Saturn V seem fairly puny. From left to right: the Boeing MLLV in its most capable form, fully stretched with a dozen 260-inch solid rocket boosters; Aerojet Sea Dragon; Rockwell Star Raker; Boeing “Big Onion” SPS launcher; Martin T10RR-3C Nova/Post-Saturn booster; early Nova “Saturn C-8;” Saturn V; Soviet N-1; Block 1 SLS; Block 1b SLS; New Glenn (scale estimated because the dimensions given for lengths and diameters don’t match up with renderings of the New Glenn).
Keep in mind, *all* of these were or are seriously considered by aerospace engineers based on the requirements of the launch market as they were then understood. Today, the markets to support these, with the possible exception of the New Glenn, simply don’t exist. But back when the Apollo program was still growing, the rocket designers of the time were seemingly convinced that the market for stuff being put into space was only going to grow exponentially.
If you might be interested in any of these as a model kit, let me know.
