Its the ability to build them quickly after they are lost is the key..Japan learnt that the hard way.

was it the FOXBAT that defected to japan and when the americans opened it up they were shocked to find vacuum tubes and similar legacy hardwear?

there is something to be said about getting the job done well with what you have around you, and Russia is great at that.

Yes. They were expecting all kinds of advanced hardware, and found out that after sustained high speed flight, the engines had to be replaced, and it used vacuum tubes.

Actually the use of vacuum tubes goes to the heart of low tech, but elegant.

The Wikipedia article about the Foxbat made a good point about the usefulness of vacuum tubes in that aircraft:

The majority of the on-board avionics were based on vacuum-tube technology, not solid-state electronics. Although they represented aging technology, vacuum tubes were more tolerant of temperature extremes, thereby removing the need for environmental controls in the avionics bays. With the use of vacuum tubes, the MiG-25P's original Smerch-A (Tornado, NATO reporting name "Foxfire") radar had enormous power – about 600 kilowatts. As with most Soviet aircraft, the MiG-25 was designed to be as robust as possible. The use of vacuum tubes also made the aircraft's systems resistant to an electromagnetic pulse, for example after a nuclear blast.


  • Tolerant of temperature extremes, thus no need for avionics cooling
  • Extremely powerful radar
  • Resistant to EMP
