I read in this week's AWST that one of the possible "second sources"
for SRBs proposed doing away with field joints entirely. Their
proposal was to assemble the entire SRB in their factory somewhere
in Florida, vulcanize the entire inner casing, then cast propellant
in one solid piece. The SRBs would then be moved to KSC via barge.
This sure sounds a heck of a lot better than continuing to use the
field joints, which sound like they will never be as secure as the
factory joints.
I think the company was United Technologies(?).

It's Aerojet-General. They have a Dade County facility with a pit
large enough to cast an SRB in a single piece. Does anyone know
if a solid motor this large has ever been built as a single piece?

According to AWST, the shuttle SRB would be the largest solid motor
cast in a single piece.

But also according to AWST, the Titan 3C and Shuttle engines are
the only significant solids to be cast in pieces, and we know what
happened to both of them.
