Project 971: Akula class

Since SOKS is a purely passive system, the sensor operator will be measuring the "strength" of the return, thus allowing more precise detection.

It's like following bread crumbs...

can we confirm this? modernized Akulas are armed with Kalibr missiles?

The Soviet Union once acquired a number of high-precision metal-cutting lathes from Toshiba to build more streamlined screws and make the subs less noisy. The news of the secret deal was eventually leaked to the media and Toshiba came under US sanctions.

Can confirm as false.

Huh?....I don't know about jet powered torpedoes, but adding Kalibr to the subs arsenal seems like a logical thing. After all, didn't the Pr.971 boats carry the Granat?

I mean do you know for sure or are you just assuming?

The main issue is securing the weights and bars when not in use.

TRX was originally developed so that Navy Seals could train in small cramped spaces – i.e. in a submarine – but the beauty of TRX is that it allows you to work out anywhere, as long as you can find something to attach the straps to.

The upgrade of Russia's Project 971 Bars ('Akula')-class nuclear-powered attack submarines will arm them with Kalibr 3M-54 (SS-N-27A 'Sizzler') anti-ship missiles, Viktor Kochemazov, chief of the Russian Navy Training Department, told the RSN radio channel on 21 March. "Now, the upgrade of the Project 971 submarines provides for equipping them with the Kalibr system," he said.

The weapon "proved itself" during trials, according to Kochemazov. "Its use by the Rostov-on-Don diesel-electric submarine showed that the system is facing bright vistas in terms of further development," he said.

He is likely to have been referring to the 8 December 2015 strikes on Syria conducted by the Project 636.3 Improved 'Kilo'-class diesel-electric submarine Rostov-on-Don . According to the Russian Ministry of Defence (MoD) at the time, this boat conducted Russia's first-ever submarine-launched cruise missile strikes on 8 December when it fired four 3M-14 land attack variants of the Kalibr missile from the Mediterranean into Syria.

At present, the Russian Navy operates a fleet of 11 Project 971 submarines, although most of these are in various stages of repair and only three boats, in service with the Northern Fleet, are operational.

Four 'Akulas' belonging to the Pacific Fleet (K-322 Kashalot , K-391 Bratsk , K-331 Magadan , K-295 Samara ) are at shipyards for repairs, with Kashalot expected to be leased to India. Bratsk and Samara have been at the Zvyozdochka Shipyard since summer 2014, Kashalot at the Amur Shipyard, and Magadan at the Zvezda Shipyard. K-419 Kuzbass has recently been released back to the Pacific Fleet, while the repair of Magadan is nearing completion.

The Northern Fleet has six submarines of the class, of which three - K-154 Tigr , K-335 Gepard , and K-317 Pantera - are operational, while K-461 Volk , K-328 Leopard , and K-157 Vepr are in various stages of repair.
