I was chatting with my father about it and as I understand it a lot of
the higher-power solid state amplifiers came out of the MRI field.
MRIs actually have really high power levels (10s of kW), though with
very low duty cycles (millisecond pulse lengths with lots of 10s-100s
of ms breaks).  I imagine there are a couple of fields where
reasonably high power and solid state are useful.  Radar is probably
another big one but those might use tubes.
