Talk:Russian submarine Sarov (B-90)

message: hangon
The lead unit of the Project 20120 submarine has been named "Sarov".  Normal usage has class names deriving from the name o fthe lead unit of the class.  Therefore, the creation of a page entitled "Sarov class submarine" is appropriate.Moryak (talk) 23:13, 28 August 2009 (UTC)

message: that's a false claim there's nothing whatsoever that makes it based on a kilo class. the size doesn't make any sense. that's a missquote from pseudo journalistic pieces  — Preceding unsigned comment added by 85.244.0.157 (talk) 01:14, 23 January 2017 (UTC)

I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.
Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.
If there is  other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page.

message: Never did understand why people go through sticking "citation needed" and "original research" labels all over an article when there are already citations right there in the article for everything. BobThePirate (talk) 01:44, 11 March 2012 (UTC)

message: It is believed the reactor does not drive the propeller itself, but rather produces electricity to recharge the conventional battery system, greatly extending the underwater endurance of the submarine. It has been noted that since electric propulsion is inherently very quiet, but tends to lack range, possession of a long range electrical system would make Sarov an excellent intelligence gathering platform.
So what nuclear powered vessels have ever been made in which the reactor does "drive the propeller itself"? How would that even work? Reactors produce one thing: heat. Heat is used to generate steam, which drives turbines which power the vessel. In this case, the turbine drives a generator to power electric motors. The main internal noise producing elements of a nuclear submarine (iei besides the [propeller and hull noise) are the coolant pumps and the turbine. This system doesn't lack either of those items. The only benefit this has is that it can serve as a battery-powered boat when silence is required, and then afterwards recharge the batteries much more quietly and without resurfacing than is possible with a diesel-electric. And since it can probably take its time recharging, it can run both reactor and turbine at low levels, which can usually be done without coolant pumps, and with far less turbine noise.
So the system does make good sense, but this description of it is extremely lacking.
