Under Admiral Gorshkov the Soviet Navy became primarily a sea control navy. This was achieved by maintaining a presence off the territorial waters of potential enemy countries, and a presence off, and within, the territorial waters of friendly countries such as Cuba, and other countries that were favorably disposed to Soviet Union. The fleet was also configured to control the sea by interdiction of enemy forces by the heavy cruisers, either the hybrids with a rear flight deck for helicopters, a sort of revival of the IJN Mogami heavy cruisers, and the heavy missile cruisers and all the various types of destroyers and frigates that accompany them, and of course the attack submarines and anti-ship missile submarines. The Baltic Fleet was to actively destroy NATO naval forces in the Baltic and create conditions for large scale amphibious landings, tho GSFG would likely have swept along the coast before any amphibious landings were needed. Perhaps the best example of this sea control philosophy was the creation of the project 949A Antei class submarines specifically designed to destroy American carrier task forces.
