BF-20’s peak thrust of 220 tons is slightly lower than SpaceX’s Raptor 2 peak thrust.
Online analysts identified BF-20’s turbopump design as similar to SpaceX’s Raptor 2 turbopump design.
Booster 15-2 is the second Super Heavy booster to be reflown with 24 of its 33 Raptor 2 engines being flight-proven.
Raptor 2 has a greatly simplified design and costs about half as much to produce as Raptor 1 while delivering higher thrust and greater robustness.
Raptor 2 can produce at least 230 metric tons of thrust compared to 185 metric tons for the initial Raptor model, and Raptor 2 thrust could later increase to as much as 250 metric tons.
