The dreadnought-era technology race crossed national borders through firms whose machinery appeared in many fleets, as the widespread use of Parsons turbines illustrates. Japan used its place in the British commercial and technical network to build domestic skill and industrial capability. Japan probably needed roughly another fifteen years within that network before it could sustain development more independently. The end of the alliance and Britain's own postwar reconstruction pushed Japan down the priority list just as the United States brought far larger resources to the same markets.
