Does the C-130 have two 1553 buses onboard? One for flight control
and one for EW/mission systems?

I don't think 1553 is used for flight control since the latency and
speed
isn't sufficient. Mission systems may well use it though. I think by
nature
1553 is dual-redundant so that's where you might get the idea of two
from.
Not familiar with the C-130 personally though.

1553 has no inherent connection with dual-redundancy.
In fact, 1553 is usually used as a single bus.

The 1553B bus is, by definition, dual redundant. Each
bus has an A and B side. Data is transmitted on one
or the other - never both at the same time.
