Soviets/successor states led in many instances. Larg(est) helicopters, Larg(est) cargo planes, Larg(est) nuke, hover transports, AFV (BMP series), hypersonic torpedoes, ground effect ships(not deployed), stealth ICBMs (to counter Reagen's Star Wars pipe dream). They aren't always the inferior that cold-war propaganda has claimed.
