I was curious what letter designation for a Space Shuttle SRB would be and found the following on another discussion thread:

Thought it was interesting to see these engines in terms that we discuss.
Okay, that's one too many gloats for me to take!
I'm a former NASA Flight Dynamics Officer -- call sign FIDO. I worked
STS-1 from Mission Control and got to watch STS-2 from the VIP area at
the Cape. (And "awesome" is right!) I also used to play on the
astronaut's basketball team.... <heh heh>
As for the question at hand:
I think the F-1 engines on the Saturn V produced about 1.1 billion
Newton-seconds of total impulse each, and each SRB about 1.4 billion
Newton-seconds.
By my reckoning, that puts an F-1 at about an AD6700000-0 and an SRB
at about an AE11000000-225 (since the chutes deploy about 225 seconds
after SRB sep).
(I'd have to dig out some of my old NASA books to verify the total and
average SRB thrust numbers, since it uses quite a shaped profile.)
