Thanks guys,

The target is Rover 2020; A challenge from a program-related engineer.

An Atlas V is 150" diameter, Shroud diameter is either 197" or 213" depending on your source and the SRBs are 62".


So I poked around the Semroc tube chart and came up with 1/100ish scale would be BT-58 to ST-20 with ST-6 SRBs. Or slightly smaller 1/120ish would be LT-115 to ST-16 with BT-5 SRBs.

1/50 scale 3" to 4" with LT-115 SRBs seems excessive. And I don't even want to think about how much Gordy would charge for that nose cone and transition.
