The Soviet capability to counter US carrier forces in other areas is less impressive. When a US carrier task force deployed to the Indian Ocean in December 1971, for example, the USSR moved in additional naval forces. The US carrier force was in the area about 10 days, however, before the major elements of the Soviet reinforcements arrived. The augmented Soviet force included two missile cruisers, a missile destroyer, and two cruise missile submarines. It had a substantial anticarrier capability, including a total of 24 SS-N-3 launchers, but it was without air support for reconnaissance or strike missions.
The combat capability of a deployed Soviet force, however, might be less important than its presence. Third parties might not recognize the disparity in the forces, or might view the Soviet force as a fore-runner of a greater Soviet involvement.
