The 1970s technology the Soviet Navy needed most

What single NATO technology would have benefited the 1970s Soviet Navy most?

Computing power and electronic miniaturization, because they constrained command systems and forced bulky workarounds across Soviet ships.

Electronic miniaturization would improve many Soviet naval systems at once by reducing the size of their computing equipment. Bulky electronics helped make command spaces larger and encouraged workarounds throughout ship designs. One proposed explanation is the Soviet preference for developing technology domestically, compared with greater willingness among Western countries to adopt one another's systems. Selling Soviet equipment abroad supported claims of technological success, while openly purchasing foreign technology was harder to reconcile with those claims. Acquiring equipment through third parties offered a workaround but added delay and effort.
