Russia has formally begun work on its next generation HUSKY Class (Хаски) attack submarine (SSN). Like other recent classes of attack submarines it is being developed by the Malachite design Bureau in St. Petersburg in the Baltic. It will likely serve in the Northern and Pacific fleets.
The HUSKY Class nuclear powered attack submarine (SSN) will supersede the Project 971 AKULA Class SSN from the 2030s. By that time the AKULA design will have been in service for about 50 years. It is also viewed as a cheaper alternative to the newer Project 885 YASEN Class SSGN which has been in very slow development for the past 40 years with the second boat (Project 885M YASEN-M) only launched on the 31st March 2017.
Note that it does not have a pump jet (propulsor). Although some Malachite designs have shrouded propellers (‘kort nozzles’), none have been built with a pump jet. Currently the Rubin design bureau appears to prefer pump jets and Malachite prefers more conventional screw-back props.
