![]() All vessels were assigned to the Northern Fleet. In 1981, with the completion of the seventh vessel, production ended. This highly experimental nature mostly predetermined their future. Project 705 boats were intended to be experimental platforms themselves, to test all innovations and rectify their faults, that would afterwards found a new generation of submarines. The first vessel was commissioned in 1971. Leningrad built three subsequent Project 705 submarines, and Severodvinsk built three Project 705K submarines (only differing in the reactor plant see below). The lead boat – the K-64 – was built in Leningrad. Production started in 1964 as Project 705 with construction at both the Admiralty yard, Leningrad and at Sevmashpredpriyatiye (SEVMASH - Northern Machine-building Enterprise), Severodvinsk. The creation of the high-speed Spearfish torpedo by the Royal Navy was also a response to the threat posed by the reported capabilities of submarines of the Project 705. Navy and prompted the rapid development of the ADCAP torpedo program and the Sea Lance missile programs projects (the latter was cancelled when more definitive information about the Soviet project was known). This combined with other reports created some alarm in the U.S. Extensively tested, she was taken out of service following a reactor accident in 1980. ![]() The long build time was caused by numerous design flaws and difficulties in manufacture. The practical problems with the design quickly became apparent and in 1963 the design team was replaced and a less radical design was proposed, increasing all main dimensions and the vessel weight by 800 tons and almost doubling the crew.Ī prototype of a similar design, the Project 661 or K-162 (since 1978 K-222) cruise missile submarine (referred to by NATO as the Papa class), was built at the SEVMASH shipyard in Severodvinsk and completed in 1972. Extensive automation would also greatly reduce the needed crew numbers to just 16 men. A high-power liquid-metal cooled nuclear plant was devised, which was kept liquid in port through external heating. The submarine would operate as an interceptor, staying in harbor or on patrol route and then racing out to reach an approaching fleet. The project was highly innovative in order to meet demanding requirements: sufficient speed to successfully pursue any ship the ability to avoid anti-submarine weapons and to ensure success in underwater combat low detectability, in particular to airborne MAD arrays, and also especially to active sonars minimal displacement and minimal crew complement.Ī special titanium alloy hull would be used to create a small, low drag, 1,500 ton, six compartment vessel capable of very high speeds (in excess of 40 knots (46 mph 74 km/h)) and deep diving. Rusanov and the initial design work led by Rusanov began in May 1960 in Leningrad with design task assigned to SKB-143, one of the two predecessors (the other being TsKB-16) of the Malakhit 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. Project 705 was first proposed in 1957 by M. As a result, the submarines were used as interceptors, mostly kept in port ready for a high-speed dash into the North Atlantic.ĭesign and development Preproduction However, it also meant that the reactor had a short lifetime and had to be kept warm when it was not being used. ![]() In addition to the revolutionary use of titanium for its hull, it used a powerful lead-bismuth cooled reactor as a power source, which greatly reduced the size of the reactor compared to conventional designs, thus reducing the overall size of the submarine, and allowing for very high speeds. The Project 705 submarines had a unique design among other submarines. ![]() They were among the fastest military submarines ever built, with only the prototype submarine K-222 ( NATO reporting name Papa-class) exceeding them in submerged speed. The Alfa class, Soviet designation Project 705 Lira ( Russian: Лира, meaning " Lyre", NATO reporting name Alfa), was a class of nuclear-powered attack submarines in service with the Soviet Navy from 1971 into the early 1990s, with one serving later with the Russian Navy until 1996.
