Theseus, from 'Blindsight' by Peter Watts. I referenced the official art, but tried to stick to the proportions and description in the book, which include an outer carapace I've never seen anyone depict. Basically an antimatter-catalyzed RAIR which acquires its antiprotons from a giant array near the sun using quantum teleportation (not how that actually works, but an honest misunderstanding). As best I can understand, the ramscoop not only collects but carries hydrogen in its magnetic field, acting as a colossal external propellant tank, and cycling that hydrogen in and out of the reactor as a mix between a Dusty Plasma Radiator and Open-Cycle Cooling For reference: https://www.rifters.com/real/Blindsight.htm https://www.rifters.com/blindsight/theseus.htm# https://www.projectrho.com/public_html/rocket/slowerlight3.php#id--Go_Fast--RAIR
