Definitely not used for flight controls. If you have ever been in a 130
and looked up you saw lots of cables that connect to actuators that run the
flight controls. Now the MC-130E has a 1553 bus for systems. I suspect the
MC-130H has two, for redundant systems. The C-130J might have more than
one, because of the FADEC and all the systems.

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.
