In 1985 Rockwell pondered the business case for a brand-new Saturn V-class expendable booster specifically for the Strategic Defense Initiative (“Star Wars”) program. The heavy payload capability coupled with large diameter payloads would allow the launch of sizable space-based lasers and similar systems. In order for the booster to warrant the high development cost, there would have had to have been a need for the capability, and obviously the USAF hasn’t filed the sky with orbital laser systems.
The launcher illustrated is not one I’ve seen elsewhere. It has three Shuttle boosters, a core seemingly larger in diameter than the Shuttle ET, and a propulsion module (presumably recoverable) with five or six engines, presumably SSMEs.
