Don't know, but saw something on Wings channel about MIGs using tubes. Also, besides EMP, you have to consider cosmic rays. A lot of NASA stuff uses rather old LSI technology because the etching is much larger than newer electronics and much less apt to be destroyed by a stray proton. Tubes would be ok if you could find a way to make the heater work more reliably... possibly coat it with something that will emit electrons at lower temperatures than usual so they could operate without that cheery red glow. Sorta depends on what you use them in too though... re-creating the Eniac on a satellite would not be practical, but using them in communications backup systems etc. would.
