Russia Designs Alternate Anaerobic Engine for Advanced Submarine
The Malakhit Design Bureau of Marine Engineering (St. Petersburg) along with the Rubin design bureau is developing an alternate air-independent (anaerobic) power plant for Russian submarines, reported
"The next step would be creation of the ship-based version of the anaerobic power plant and its sea trials. Currently, we’re arranging for performance of these works under a contract with the Russian Ministry of Industry and Trade", said Igor Ponomarev.
He recalled that a mockup model of the air-independent powerplant had been already assembled by the Rubin design bureau.
Media reported early in 2016 that the new Russian non-nuclear submarine named Kalina and equipped with anaerobic engine might start in 2017. The key advantage of the air-independent powerplant is better acoustic discretion of a submarine which may stay submerged for a longer time, up to 2-3 weeks, without the need to surface to charge batteries.
