The verified answer
As of Sep 2026, DEPLOY verifies Dream Chaser (Tenacity), a space by Sierra Space (research). 2 sources back the record.
Overview
Sierra Space lifting-body spaceplane designed for autonomous orbital flight and autonomous horizontal runway landing (GN&C from Draper). Honest flight status: it has NOT yet flown to orbit. Atmospheric drop-tests of an engineering article (2013-2017) preceded it; the first orbital flight of the 'Tenacity' vehicle is no earlier than late 2026 and the original CRS-2 ISS cargo missions were cut to a single uncrewed demo (contract modified 2025-09). Autonomy is designed, not yet demonstrated (verified-vs-claimed).
