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

Aha, this makes the things clearer.
I could also arrange a drawing with a Titan 34D....

My nitpick with the drawings (as beautiful as they are) is seeing only two engines on the NLS core vehicle.  I suppose that NLS would have looked like a stretched Shuttle ET with six engines on the core (the four around the perimeter dropped off like the booster engines on the Atlas.)

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).

Although DreamChaser didn't win an initial COTS award, it has been granted some more recent funding (some details in the DreamChaser thread at http://www.secretprojects.co.uk/forum/index.php/topic,4389.0).

Inasmuch as I loved the Dyna-Soar, M2 and X-24 lifting body designs, I always hated this bugger. Looked like a badminton shuttlecock to me!
