Mostly Military because 400Hz allows you to use smaller cores in transformers and things, but it shows up in other weight-critical applications.

Huh, I thought it was somewhat common in railway too. Pretty sure we made some parts for that application but it's been a while, I might be misremebering. I'll ask my co-worker, could be for auxiliary equipment.
Yeah, higher frequency, smaller cores. We know the drill from SMPS. It felt quite weird when the wall warts' weights changed from a pound to three ounces at higher output wattage.
