Carina SSTO Heavy Cargo Shuttle Allow me to present the Carina. This is a single-stage-to-orbit spaceplane using the B9 Aerospace and Quantum Strut mods. It is capable of placing a 40 ton payload (> large orange tank full) into a 100km circular orbit. Best of all, it looks sexy as hell. It includes a fully enclosed cargo bay for the best possible aesthetics. This video also provides a good overview of the methodology for achieving stable orbit with an SSTO. Craft files:
