It's interesting to see so much similarity with BOR-4 (https://en.wikipedia.org/wiki/BOR-4 and http://buran.ru/htm/bors.htm), particularly foldable wings. Surely DC is bigger and much more polished, but it's still reminding of the past programs.

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.

There'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) 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.
