It's not explicitly clear (in english) from your links, but there is true design lineage from BOR to Dreamchaser. The HL-20 mold line was derived from spy plane imagery of BOR-4, and HL-20 was then the design basis for Dreamchaser.

- avmich 2y agoThere's a long chain of influences across the border in winged spacecraft development. Dyna-Soar (https://en.wikipedia.org/wiki/Boeing_X-20_Dyna-Soar https://en.wikipedia.org/wiki/Boeing_X-20_Dyna-Soar) project in USA pushed works on Spiral' project in USSR, and BORs are a part of that. It arguably provides a link from HL-10 via USSR projects to HL-20, among other things.
