This image was passed along to me; it came from an ebay auction from some time in the past. No further info than this illustration, but it is clearly a Boeing “control configured vehicle” bomber concept.
I know it’s a Boeing design because a year and a half ago I lost out on an ebay auction for another piece of concept art showing the same aircraft, this time with “Boeing” clearly visible on the engine nacelle:
And I know it’s a Controlled Configured Vehicle because in the early 1970’s, Boeing studied a bomber that was very similar in configuration to this, known as the “CCV-100-2.” There are some obvious differences, such as the cockpit canopies and the engine inlets, but the overall configurations are very similar. The CCV-100-2 received a tiny bit of press in Aviation Week, and was granted a design patent for the overall shape. Sadly, I do not have anything on performance or dimensions; if anyone *does* know more about this, please let me know.
