CFE said:Is there any detailed info on OSC's attempts to bring back HL-20 for OSP in 2001-2002? Their initial artwork looked very much like the traditional HL-20 layout. As the project progressed, the HL-20 outer fins got bigger and lost their dihedral, essentially becoming wings.

I wondering the same by myself, anyway my reference (based upon NASA material) clearly speaks about Titan IIIC, please look at the following image.
Byeman said:It has 5 1/2 segments on the solids, which would mean Titan 34D.
Edit: Actually it could be a Commercial Titan III (no transtage and therefore no "C" designation) NASA did buy one for Mars Observer
archipeppe said:In effect the original HL-20 proposal was recycled twice: the first time for the OSP proposal, around 2000, and the second time for the DreamChaser second layout for COTS (taking into account that not fresh new are about it since a couple of years).
