Orbital Spaceplane

3D Model

Concpet single-stage to orbit spaceplane. Created as part of Spaceshiptember 2023 for the realism prompt.

While no such spaceplane exists, it’s designed around only existing technologies: two jet engines, which would be something like a larger/updated version of the SR-71’s Pratt & Whitney J58, and several aerospike rocket engines like the ones developed for the Lockheed X-33 spaceplane.
