XCOR Lynx, a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane, that only reached the stage one of its development.
The XCOR Lynx was a proposed suborbital horizontal-takeoff, horizontal-landing (HTHL), rocket-powered spaceplane that was under development by the California-based company XCOR Aerospace to compete in the emerging suborbital spaceflight market. In May 2016, XCOR announced development of the Lynx had been halted with layoffs of approximately one-third of the staff; the company intended to concentrate on development of their liquid hydrogen rocket under contract with United Launch Alliance, instead. In May 2016, the company halted development of the Lynx spaceplane and pivoted company focus toward development its LOX/LH2 engine technology, particularly on a funded project for United Launch Alliance.
