So that’s a proposed upgrade from about 2,460 kN to 2,847 kN per BE-4, or about 15-16%. If nothing else it’ll help NG do something other than crawl upwards off the pad. (For reference, Wikipedia says Raptor 1 was 1,810 kN, R2 is 2,260 kN, and R3 will be 2,750 kN.)

Also, this part about the heavy variant just bugs me:

The vehicle carries over 70 metric tons to low-Earth orbit, over 14 metric tons direct to geosynchronous orbit, and over 20 metric tons to trans-lunar injection. Additionally, the 9x4 vehicle will feature a larger 8.7-meter fairing.

Rocket companies saying their paper rockets do something (in the present tense) is terrible. It does nothing yet. It’s a design, not a vehicle. But BO can’t even keep that present-future tense consistent within the same paragraph.
