Neutron is not fully reusable. The second stage is thrown away. It's a good design for partly resuable, though -- the second stage is tiny, and the fairings are part of the first stage rather than separating. > The reason that I didn’t include Blue is that AFAIK, it is not being manufactured at the moment, unlike the other three. Neutron, Relativity R and Stoke aren't being manufactured yet either, so I'm not sure what the distinction is.

  Blue Origin is developing both reusable and non-reusable 2nd stages in tandem: "We're also working on a reusable second stage. Right. 46:20 And we're gonna let that be a horse race. So the, the goal for the expendable stage is to become 46:26 so cheap to manufacture that reusability never makes sense. Awesome. And the goal for the reusable stage is to become 46:35 so operable that exp expandability never makes sense. And so it's, and we will see 46:41 because when you do that trade on paper, it just isn't obvious. Right. Right. 46:47 On the first stage it's blindingly obvious. Right, right, right. Yeah. It's like the bulk of 46:54 the cost. - It's lowest velocities. Yeah. Correct. It's everything lines up for reusability. Yeah. 47:01 For the second stage, it's an interesting horse race. Yeah. So we're just gonna go barreling down both paths. 47:09 And try to figure out which one is better. Really. Yeah. And 'cause it's just about cost. - At the end 47:15 of the day. Yeah. At the end of the day it's just about cost - Are where you actually at in terms of that second stage, the reusable second stage." https://youtu.be/rsuqSn7ifpU?si=4_cm2khyEP0as4aF&t=2771 https://youtu.be/rsuqSn7ifpU?si=4_cm2khyEP0as4aF&t=2771
