In the late 1970’s Rockwell international studied the “Star-Raker,” a large airbreathing horizontal takeoff and landing SSTO designed to support the Solar Power Satellite program. This 2,268,000 kg gross weight vehicle would have a payload of 89,200 kg; the claim was that this vehicle could fly roughly daily and very cheaply. Of course, at about the same time Rockwell was claiming that the Space Shuttle would have a two-week turnaround and would be the cheapest ticket to space…

While Star-Raker was far from the biggest or most powerful launcher studied for SPS, it was certainly one of the more interesting concepts. While a number of SPS reports have described the Star-Raker, to my knowledge a dedicated Star-Raker design report has not come to light. If anybody knows of such a thing, by all means let me know.

Star-Raker garnered a bit of press back in the day, likely due in part to the fact that Rockwell released a number of pieces of concept art, like the one below showing the vehicle in orbit.
