Where does the Lockheed Martin Orbital Space Plane fit into this?

Where does the Lockheed Martin Orbital Space Plane fit into this?

We reconstructed the "family tree" of HL-20/42 but it does not comprehend the Lockheed-Martin OSP proposal.
The only real HL-20/42 derivative is, currently, the SNC Dream Chaser.

A well done presentation. Shouldn't the X-20 Dyna-Soar have been included in the family tree?

Thanks for the appreciation, X-20 was out of the scope of the presentation since HL-20/42 evolved from the Russian Spiral OS/Bor-4 rather than any other American previous spaceplane project.

also not the Lockheed-Martin CEV has from the design probably it's origins from Lifting Body like M2F2 or even older ones the M-1.
