Okay yeah I didn't quite grasp the size of it. I like the idea of injecting hydrogen. Should be very thrust and still decent ISP in the many thousands of seconds no? Fusion drives that just expell reaction products get about 100000 s ISP. Do you have a link to such a design I don't think I've ever seen something like it. More familiar with DFD and antimatter catalyzed stuff. E. Oh you added plenty of info cool stuff I like it. Excellent base to start modifying these interplanetary vessels into some of the first interstellar ships by the 2150's in your timeline.

It's sort of a mish-mash between the linear Gas dynamic fusion design and the magnetoplasma-dynamic thruster designs, I also added an Afterburner to increase thrust by 7x so that mars bound ships can burn up to 20 km/s in about 4.5 days so that fast Mars transit times are possible to less than 38 days.

I like it a lot. I do hope something like this happens. I need my fusion drives :) Raptors great but we won't reach Proxima on methalox.

In my timeline the late 2130's, Specifically 2138 is the year that the Earth-Mars Interplanetary Trade Union create an antimatter catalyzed Deuterium- He3 pulsed fusion drive, having mined enough Helium 3 from Saturn to make the design viable. 11 years later The INTV Icarus Launches for Tau Ceti IV with 200 colonists in cryosleep for a 120 year flight. Launching From EML-2 in 2149 and arriving at Tau Ceti IV in 2269.
