...and Boeing’s rocket will be cheaper as they will have it mostly built in China.
Actually it’s far more expensive than Falcon Heavy. To the tune of billions of dollars more expensive. The development cost so far, and it hasn’t even flown yet so that number is still climbing, would be enough to fully develop the Falcon Heavy and fly it in fully expendable mode about 63 times. That’s enough to send about 1 million kg to Mars, or put about 4 million kg in low earth orbit. 4 million kg in low earth orbit would be about the quarter of the known mass of all known satellites ever launched combined, not counting classified payloads of course. Just some numbers to keep in mind.
