Russian Navy wants the end of 2012 to conduct tests of the submarine B-90 «Sarov» Russian first experimental engine on hydrogen fuel, the newspaper «Izvestia» citing a source in the Defense Ministry. In the future, such power plants can be equipped submarines Project 677 «Lada» and «Amur-1500». Such engines are German submarine U-212 projects and U-214.
According to the source newspaper, classic diesel-electric submarines, for example, Project 636 «Varshavyanka» use batteries that feed the motor. When they need to exhaustion submarine swim and run diesel engines, so again to recharge the batteries. This makes ships vulnerable. In the case of hydrogen engines, electric motors powered by hydrogen fuel parts.
New Russian engine is a type of propulsion airindependent. He, like other engines such type can significantly increment snorkeling non-nuclear submarines. In addition, due to they are able to significantly reduce the noise of ships. According to a source, «Izvestia» in the Russian Navy, with the latest airindependent powerplant Russian submarines will be able to make konkurentnst German projects.
In July 2012 Commander of the Navy of the Russian Federation Viktor Chirkov decided to resume construction of the diesel-electric submarines of Project 677, stopped the previous commander in chief Vladimir Vysotsky. Earlier navy was not satisfied with the latest properties airindependent powerplant for Project 677; he sought its completion.
Under the project 677 is built in Russia until only one submarine — «St. Petersburg» passing tests. In addition, in various stages of readiness are ships «Kronstadt» and «Sevastopol» the same project. Their construction is suspended. As the «Izvestia», the construction of submarines may resume if the hydrogen engine tests run successfully.
B-90 «Sarov» is towing a submarine designed by only 20,120 in 2008. The ship was built on the basis of the experimental submarine corps of «Gar», begun in the late 1980s, but unfinished due to lack of funding. Displacement «Sarov» is about 4 thousand tons. The submarine is designed to test new weapons and technology.
