    Wow that’s impressive.

    Is it because the first two were prototypes so they bolted on whatever they needed without care for it looking nice or did they just refine it so much that they were able to simplify the design significantly?

      That and the march of progress, despite what some people believe we are still evolving at a rapid pace and engine outputs have significantly increased recently.

      The first two prototypes looked like what traditional rocket engine looks like.

      For example:

      The RS-25 engine that equipped the space shuttle and now the SLS launcher

      The Vulcain 2.1 that is on the Ariane 6

      SpaceX put a lot of work on refining the engine, they also already produced more than 600 engines ! It’s a crazy amount !

      It’s more of a refinement thing, where anything not absolutely necessary is removed, or 3D printed straight into the structure of the thing instead of added to the side.

    At this rate the Raptor 13 will be a platonic cone, and the 300 will be singular point in manifold space

    That is pretty impressive. Going from a clusterfuck of tubes and pipes to a very clean looking engine

    FWIW the Raptor 3 here does not include the turbopump mechanism. It would look pretty much the same as the raptor 2 (which does have the pump attached).

      No, that’s wrong. This is, in fact, the entire engine. It’s not missing anything. It was test fired in this configuration. It honestly looks surreal.
