Fission is required for D-T fusion at this point, otherwise you don’t have any tritium. It’s the people who ignore that, and our failure to breed tritium within a fusion reactor who are disingenuous. If you don’t know even that much about the science, I’d strongly recommmemd refraining from accusing people of being less tham forthright.

Per the article, it sounds like the fusion reactor itself could indeed be the thing producing the tritium by way of a lithium blanket. Of course, that means it'd need to have some way of generating the neutrons (the design seems to include two spots for "neutral beams", but I missed any mention of what's supplying those beams).

It is today, but my understanding is that fission is just our best source of neutrons to breed tritium from lithium 6. Fusion should also be an excellent source of neutrons, so I don't see that as being a hard requirement. I'm not a physicist, so I may be dead wrong.
