[Milsurplus] 400 cycle 3 phase and WW2

[Jack Antonio]

I  remember reading that the Douglas XB-19 which was
used as a test bed for large aircraft systems, used AC power,
but no technical details were provided.

Being that AC distribution reduced design weight by several thousand pounds on a large aircraft. Recall reading something along this line in "Magnesium Overcast" by Dennis Jenkins. Maybe there was some application of 400 cycle AC prior to the B-36 but don't know what it would be. Did the old GO and GP transmitter have engine driven generators or motor generators  to develop their voltages from the ships DC distribution?
