Is that true? I can imagine that cases when you don't want them flopping
around, assuming power is needed to keep them in place, or to preposition them
before a burn, but the rest of the time ground power may be available.
I had actually argued at a previous job for powering the gimbal actuators from
the pump batteries.

If you need serious power for actuators, it could easily make sense to
add a generator to a turbopump shaft -- it's common to hang auxiliaries
