I would interpret your question as a NASA or other countries most powerful rocket, if you are looking for an amateur rocket that would be the CSXT Go Fast Rocket from 2014 iirc it was an S-motor.What is the most powerful national rocket ever? Did it reach Z?
They dont use letter classes however, someone has extrapolated letter equivalents for motors over S, I am unable link it from my phone but its available on Wikipedia iirc a Space Shuttle SRB is a AD equivalent.So S for amateur.
Yes, what equivalent would be the strongest NASA or other national rocket?
Thats the link, thanks.Way beyond Z. The still undisputed worlds champion rocket is the Saturn V . Someone came up with this chart on Wikipedia: https://en.wikipedia.org/wiki/Model_rocket_motor_classification
I think that's the one you were looking for Rich. :blush:
