I did watch and from there I extracted an info that Obninsk is at Nerpa for repairs and possible some additional upgrade (even though it passed modernization in 2013).

These are fantastic submarines. The name "Obninsk" doesn't ring a bell though?

Cozy
What a nice name for something so small that they had to make door selection for crews

Ok thanks I thought you were referring to the Pr.971's.

Expanded news from last days:

Nuclear submarine "Tiger" project 971 "Pike-B" in the course of modernization will receive new weapons

The multi-purpose nuclear submarine (NPS) "Tigr" of project 971 (code "Pike-B"), undergoing repairs with modernization at the Nerpa shipyard (a branch of the Zvezdochka ship repair center), will receive a new weapon system. This was reported by a source in the defense industry.

The modernized "Tiger" will be armed with the package complex "Caliber-PL", as well as two other submarines of this project - "Leopard" and "Wolf", undergoing modernization at the TsSR "Zvezdochka". The submarine should receive new electronic weapons, a control system, communications, navigation, hydroacoustics, CIUS. Earlier it was reported that technical readiness would be returned to the submarine, the modernization of weapons was not envisaged.

Nuclear submarine "Tiger" after modernization at the plant "Nerpa" will return to the combat strength of the Northern fleet, armed with the Caliber complex

- leads TASS source words.

The return of the "Tiger" to the combat strength is planned for next year, although earlier it was said about 2022. In this year, the Leopard nuclear submarine of project 971 will return to the Northern Fleet, and in 2023 - the Volk nuclear submarine of the same project. All submarines are part of the 24th "Animal Division" of the Northern Fleet of the Navy. In total, the division has 6 submarines - "Leopard", "Wolf", "Tiger", "Vepr", "Panther", "Cheetah". The last three are in the combat composition of the fleet.

The nuclear submarine "Tigr" is considered to be under repair since the mid-2010s, but the repair of the submarine at the Nerpa shipyard (a branch of the Zvezdochka ship repair center) began in 2019.

The K-154 "Tigr" submarine was laid down in 1989 in Severodvinsk, launched on July 10, 1993, and joined the Northern Fleet on December 5, 1994. The submarine was built according to a project with improved acoustic stealth. Characteristics: The greatest length - 110,3 m; maximum width - 13,6 m; average draft - 9,7 m; total displacement - 12770 tons; working depth of immersion - 520 m; maximum immersion depth - 600 m; full underwater speed - 33 knots; surface speed - 11,6 knots; autonomy - 100 days; crew - 73 people.

Armament: 4 torpedo tubes 650 mm, 4 torpedo tubes 533 mm, torpedoes, mines, anti-ship and anti-submarine missiles.

BTW, shouldn't this thread be renamed to Shchuka-B Class instead of Akula?

It should be called Pike as it is an English language forum, but it is known in the west as Shark (Akula), but obviously the Soviets and Russians call their Typhoon class subs Shark (Akula)...

It is potentially very confusing.

BTW information about Calibre-PL is here:

http://roe.ru/eng/catalog/naval-systems/shipborne-weapons/club-s/

This is Club-S, which is the export equivalent... much shorter ranged missiles of course due to export restrictions.

Attack submarine of the Northern Fleet K-157 "Vepr" (Boar).

I wonder how far the tests on the submarine K-328 "Leopard" of project 971M have come.

Looks like they may be starting repairs on Nerpa soon.

Possible dates for the return to service of the multi-purpose nuclear submarine "Leopard"

The return of the Leopard multi-purpose nuclear submarine of project 971 (code "Pike-B") to the Northern Fleet after repair and modernization is planned approximately for December 2023. This was reported to TASS by the head of the All-Russian Fleet Support Movement Vladimir Maltsev.

“After the completion of a deep modernization and factory testing, the transfer of the Leopard to the fleet is planned for December 2023,” he said.

The multi-purpose nuclear submarine K-328 "Leopard" was built at Sevmash and handed over to the fleet in 1992. In 2011, the submarine arrived at the Zvyozdochka Ship Repair Center to undergo a medium repair and a deep modernization.

At first, they planned to return the submarine to service in 2018, then the deadlines were shifted by another year. At the end of 2020, the press service of the Russian Ministry of Defense reported that the final stage of the modernization of the submarine had begun.

In December 2021, Zvezdochka CEO Sergei Marichev announced that testing of the submarine would begin in 2022.

Currently, the 24th ("animal") division of the submarine forces of the Northern Fleet has three nuclear submarines of project 971: "Panthera", "Vepr" and "Gepard".
The standard weapons of the Project 971 submarines are torpedoes, mines, anti-ship and anti-submarine missiles. They can be launched from four 533mm and four 650mm torpedo tubes. These submarines are capable of reaching a depth of 600 meters and moving underwater at speeds up to 30 knots.

According to TASS sources, after the repair and modernization of the Project 971 nuclear submarines, their arsenal of weapons on board will remain the same - 40 missiles and torpedoes, but it will be expanded with Kalibr-PL cruise missiles.

Was Irbis ever broken up or is it still sitting 42% complete. in some yard rotting. Did India agree to lease it?

As of Nov 2019 she was still in storage. Now, who knows?

Above link indicates that an Akula is to be delivered to India by 2025 for a 10 year lease. Since its 3B one would assume this will be a brand new sub, if not massively  refurbed.

Its likely Russia got India to fund development of a major upgrade config for the Akula and is implementing parts of it into the current fleet as they complete Irbis as Chakra III.
