A larger Soviet surface-raiding fleet in the 1950s

How would Britain and the United States respond if the Soviet Union built a much larger Sverdlov-class force and completed the Stalingrad-class battlecruisers in the late 1950s?

A global Soviet raiding fleet would force a different Western naval policy and could preserve a British program for new aircraft carriers in the late 1950s.

The scenario combines a much larger Sverdlov-class cruiser force with completed Stalingrad-class battlecruisers, giving the Soviet Navy a stronger worldwide raiding presence. Western navies would need more forces able to find, shadow, and intercept those surface groups. That threat could supply the strategic justification for a new Royal Navy carrier generation in the late 1950s. A shipbuilding program must be judged partly by the counterforce and alliance investment it compels from an opponent.
