Soviet electronics and command-economy incentives

Why did Soviet electronics designers produce impressive vacuum-tube technology without turning it into a broader civilian market advantage?

A command economy could assign resources to military applications, but it lacked the same market pressure to turn clever components into cheap, widely adopted civilian products.

Soviet technical ingenuity operated within a system where the state chose resources and applications from the top. The opening comment contrasts Western wartime component overproduction and the postwar collapse in consumer-electronics prices with a Soviet semiconductor program that missed part of the microwave-diode learning curve. Soviet engineers compensated with innovations such as low-power rod tubes for guided missiles and fire-control computers. Western consumer markets created different pressures through demand for labor-saving devices, lower costs, and wider applications. Top-down allocation could fund an impressive component without creating an equivalent incentive to turn it into a cheap, widely adopted civilian product. A navy's electronics base depends on industrial incentives and civilian spillover as well as talented engineers.
