Russia celebrates 90th anniversary of the Soviet Navy

In some respects, including speed and reactor technology Soviet submarines were, and remain, some of the world's best. Their primary shortcomings were insufficient noise dampening (American boats were quieter) and sonar technology. The Soviets possessed numerous purpose-built guided missile submarines, such as the Oscar class, as well as many ballistic missile submarines and attack submarines. The Soviet navy's Typhoon class boats are the world's largest submarines. The Soviet attack submarine force was, like the rest of the navy, geared towards the interception of NATO convoys, but also targeted American aircraft carrier battle groups.
