Soviet submarine K-162 was the world's fastest submarine. The first submarine constructed with a titanium hull, she was the only vessel of the Soviet Union's Project 661 Anchar nuclear-powered attack submarine design. The boat is best known in the West by its NATO reporting name Papa class. K-162 was renamed K-222 in 1978.
The project was intentionally forced to be highly innovative, as it was forbidden to reuse prior technical solutions. While enforcing innovation, this also slowed the development. Project 661 began in 1959, with design task assigned to OKB-16, one of the two predecessors (the other being SKB-143) of the famous Malachite Central Design Bureau, which would eventually become one of the three Soviet/Russian submarine design centers, along with Rubin Design Bureau and Lazurit Central Design Bureau.
K-222 was designed as an extremely fast attack submarine, and was the first submarine built with a titanium hull. She was armed with 10 SS-N-7 Starbright (П-70 «Аметист») missiles in individual tubes forward of the sail, between the inner and outer hulls, which were both of titanium alloy. Similar in design to the Charlie class, K-222 was designed to intercept and attack aircraft carrier groups. Like the Charlie class and the later Oscar class, her cruise missiles could only be reloaded in port, making her one of the Soviet Navy's "one shot" boats.
K-222 had two light-water reactors, designed to be as compact as possible. Unusually, there were no diesel generators, using the powerful battery as the emergency power source.
