[net.space] electronics in Foxbat

henry (07/01/82)

People who criticize the Foxbat's electronics as primitive obviously
saw only the mass-media reports on it.  After the first wave of
contempt, the people studying it were much impressed with what they
saw.  True, the stuff was much inferior to what the West can do, but
it was an impressive use of the available technology.  In particular,
it is far cheaper to build than it would have been if it had been
designed in the West, even to equivalent specifications.  Remember,
the total number of Mach 3.0 (or even Mach 2.8) combat aircraft in
service in the West is *zero* -- and the Foxbat prototypes started
flying nearly twenty years ago.  That last point is worth emphasizing:
the Western fighters that were being tested and built when the Foxbat
started flying were among the first combat aircraft to use transistors
instead of tubes.  At the time, using tubes in the Foxbat was the
only sensible approach -- Russia was of course behind in semiconductor
technology, while tubes were cheap and available in quantity.  It's
also noteworthy that the Foxbat's electronics are (by design) much
easier to maintain than those of its Western contemporaries, or even
those of more recent Western aircraft.  And while that radar may be
crude, its power output is so high that it's virtually unjammable.

The Foxbat obviously could do with more modern electronics, and there
is considerable speculation that just this is in the works.  Bear in
mind that the Russians seldom hold up production of something that
works just because something better is on the way (a habit that tends
to plague Western defence purchasing).  It would not surprise me if
the computers on a hypothetical Russian shuttle were crude, barbarous,
and primitive by Western standards, but worked well enough to do the
job, and were carefully used so as to minimize the impact of their
shortcomings.
