Western response to a large Soviet cruiser program

Would a much larger Soviet Project 69 or Project 68 cruiser force trigger a Western naval response?

Yes; completing the planned Project 68 force would likely provoke a new Western light-cruiser generation in the 1960s, armed with a mix of 6-inch guns and missiles.

The incompletely realized Project 69 concepts differ from the fourteen Project 68 Sverdlov-class cruisers actually built and the thirty once planned. Completion of the larger program would represent a major force increase that Western navies could not ignore. A likely answer is another generation of light cruisers combining 6-inch artillery with emerging missile armament.
