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

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.)

Thought it was interesting to see these engines in terms that we discuss.
 
His number is correct for the F-1.

As for the shuttle SRM, I'd call it an AE12455000. Which would get an Alpha way up there.
