Best Website Yet on Characteristics of Soviet/Russian Naval Platforms Including Submarines
By Bruce Rule - Feb 25, 2014
The website http://russian-ships.info/eng/submarines/ – with a link below - provides detailed information on Soviet and Russian nuclear and diesel submarines to include (for many) hull designations (K numbers), shipyard, lay-down, launch, commissioning dates and current status, displacement, dimensions, depth capabilities, reactor designations, marine propulsion power train designations and horsepower, SSTG designations and ratings, diesel-generator designations and ratings, secondary propulsion system ratings, weapons and decoys, radar, sonar, combat (fire-control), communications and navigation systems designations.
The following is provided for Project 971 (NATO: AKULA Class): 1 nuclear reactor OK-9ВM x190 MW, 1x50000 hp GTZA OK-9VM, 1 fixed pitch propeller, 2x560 hp electric motors, 2 thrusters, 2 turbine-type generators x3200 kW, 2 diesel generators x750 kW.
The following is provided for Project 955 (NATO: BOREY Class SSBN): 1 nuclear reactor OK-650B x190 MW, 1x49000 hp GTZA OK-9, 1 pump-jet, 2 turbine-type generators x3200 kW, 2x400 hp electric motors, 2 diesel-generators x 500 kW.
http://forum.paradoxplaza.com/forum/showthread.php?606552-About-the-new-Russian-submarines-which-will-be-in-service-with-Russia-in-2030 further describes the BOREY power as a GTZA OK-9VM, the same system used by AKULA Class units.
Note: the acronym GTZA translates to (quote) main turbine gear assembly (end quote) and thus represents a single machinery unit that includes the main propulsion turbine and the reduction gear.
The site also includes interesting information on older Soviet nuclear submarines, e.g. NOVEMBER, ECHO and HOTEL Classes, all of which have the same propulsion system described as (quote) 2 nuclear reactors VM-A x70 MW, 2x17500 hp GTZA-601, 2x450 hp electric motors PG-116-1, 2 diesel-generators DG-460 x460 kW, 2 turbine-type generators GPM-21 x1400 kW (end quote).
The also provides information on Soviet/Russian surface including the following on the Soviet nuclear-powered cruiser KIROV (Project 1144): 2 nuclear reactors VM-A x70 MW, 2x17500 hp GTZA-601, 2x450 hp electric motors PG-116-1, 2 diesel-generators DG-460 x460 kW, 2 turbine-type generators GPM-21 x1400 kW
