Raptor 3, SN1
“The amount of work required to simplify the Raptor engine, internalize secondary flow paths and add regenerative cooling for exposed components was staggering. As a result Raptor 3 doesn’t require any heat shield, eliminating heat shield mass & complexity, as well as the fire suppression system. It is also lighter, has more thrust and has higher efficiency than Raptor 2. Truly, a work of art.”
