They Semroc/eRockets were going to introduce a “Pro” line to replace the “SLS” line. They showed off some models including upscales of the Orbital Transport, Mars Snooper, and BBZ on NARHAM 2020 manufactures video. Randy had some health issues since then, but I believe is doing well now. Maybe they just pushed the projects back a little, or the economics do not work out right now.
