Project 11356: Admiral Grigorovich

If it hasn't already been asset stripped then it will likely be destroyed or sabotaged.

Would not expect anything useful to be found there any time soon and certainly not worth a cent to fix up afterwards.

Why cant the grigoroviches use the gas turbines of saturn?

Ships propulsion systems are a bit like car propulsion systems... it is not like you have an engine and an accelerator pedal that goes from naught to top speed.

The engine of a car has an efficient running speed and a power running speed... most 2 litre cars 2 to 3 thousand revs for travelling at 100km/h on the motor way, 4-5 thousand revs for accelerating or climbing hills with loads on.

A ship generally has quarter, half, three quarter and full flank speeds forward and a reverse speed or two. The hydrodynamic shape of the hull and the propeller means it wont be able to go backwards as fast as it can go forward.

Most naval diesel engines can be stopped and then run backwards so no special gears are needed to run backwards.

A combined gas turbine and diesel powered ship the quarter speed power setting is usually running on diesels and it most efficient but also rather slow.

A ship with diesels and gas turbines use the gas turbines for sprints at max speeds...

The point is that for different jobs different speeds are required or desired... if you look at the Udaloy and the Sovremmeny class ships the former is a sub hunter and the latter is a destroyer so they have different roles with different speed requirements so they have quite different propulsion systems too.

For the new ships they need to be flexible because they will be used for a range of different roles for which different speed capabilities will be valuable.

For short range light transport aircraft sometimes a turboprop is more efficient than a low bypass turbofan... if you get it wrong you end up with a plane that burns too much fuel for what it does, or you end up with a plane that is too slow or too short ranged to be useful.

The Admiral Grigorovich was an interim design while they couldn't get the Admiral Gorshkov working.
It makes no sense to continue building them at this juncture.

It's more accurate to call the 11356s an insurance policy in the event that the 22350s didn't meet expectations. The 1st 11356 was laid down in the same year as the 1st 22350 was launched.

Yantar builds 3 - 11356 for the Indians
IMO these should go to the BSF

I don't understand why this Shipyard makes for India in time of the SMO

For those who said this class was unneeded, Well look at the state of the sad VMF now

Can you still say these ships are not needed? Where is 22350 in numbers? That's right nowhere still playing with first serial ship and zircon

11356 is desperately needed to increase firepower of the BSF - Shtil is undesirable, but acceptable

Redut carrying ships will not be a thing for the BSF for a while, Shtil is all it can expect for now

Until Zaliv or Zelenodolsk builds some Redut ships, BSF can stop dreaming of long range AD

What are you writing about, those frigates were sold and the Russians got money for it..
And no, Russia does not need these frigates anymore. The air defense system is also better on the 20380 corvettes although with fewer launch cells. Project 20385 corvettes also have one UKSK as do 11356 frigates. For God's sake, these frigates don't even have a Paket-NK anti-submarine system.

Russia, India sign contracts on building 4 Project 11356 frigates
Russia’s Federal Service for Military and Technical Cooperation stressed that this was "another important event in developing Russian-Indian military and technical cooperation"

MOSCOW, November 20. /TASS/. Russia has signed contracts with India on the construction of four Project 11356 frigates for the Indian Navy, Russia’s Federal Service for Military and Technical Cooperation said on Tuesday.

"Contracts were signed for the construction of Project 11356 frigates for the Indian Navy. This is yet another important event in developing Russian-Indian military and technical cooperation," the Federal Service said.

Russia earlier held negotiations with the Indian side on the contract on the acquisition of four Project 11356 frigates. The Indian media reported that the government of India wanted to buy four Russian frigates that would be built in the 2+2 format: two would be constructed at Russia’s Yantar Shipyard on the Baltic coast and the other two at India’s Goa Shipyard.

Project 11356 frigates are designed to deliver strikes against enemy surface ships and submarines in the close-in and oceanic zones and fight air targets. The warships of this type are armed with A-190 100mm artillery guns, strike missile and air defense systems, including Kalibr and Shtil complexes and torpedo tubes. The frigates displace 3,620 tonnes, are 124.8 meters long, develop a speed of 30 knots and have an operating range of 4,850 miles.

Russia needs project 20385 corvettes and project 22350 frigates - that's all.
All the rest are forced measures such as project 22160 patrol ships, frigates 11356R, 22800 MRK, etc...

How can 20380, which is built by severnaya pass through bosphorus to reach BSF?

can 20380 pass through canal system ?

IMO 11356 is still fit for service in BSF,

ASW duties can be done by 22160 with ASW container module

But let's not pretend MOD can just sell these ships to India, right now the money is less important than filling out the BSF

The contract for the sale of frigates was signed in 2018 and I sent you a link about it - should I draw it ?

It is not just a matter of money (but they do not hurt either). It is also about credibility and keeping good relationships with India. Since India did not impose sanctions against Russia and did not provide weapons to Ukraine there is no justification for cancelling the contract.
Russia is not France or US.

Furthermore 20380 (including its modernisations as the later ships of the serie include also some solutions from 20385), while smaller than 11356, is a more capable ship which only disadvantages in comparison to 11356 are a lower range and endurance (and a slightly lower top speed).

By the way, were the engines for the last frigates already delivered from Zorya Mashproekt before 2022? If not it will be difficult for them to be completed. Furthermore India wanted to build also a couple more frigates in Goa... I doubt Zorya will ever be able to produce those engines again...

In theory Russia can now produce engines with similar performance. M90FR and M70FRU. But a reduction gear would have to be designed and produced. It is claimed that the future 22350M destroyers will use a similar propulsion scheme, so it might be that if India waits something will be available.

From what I heard the propulsion had been delivered by Ukraine for two of the ships in India, but I do not know about the other one.

As far as I could understand, 22350M should have a similar size to the udaloy class anti sub destroyer, so it is not really the same, unless you meant a. Combined Gas turbine and gas turbine propulsion system (COGAG) instead of the combined diesel and Gas (CODAG) of the baseline 22350.

Anyway, possibly after finishing the first two ships, Russia could propose India an export version of Gorshkov class.

I do not agree, 22160 and 22800 have very useful roles.

22160 are relatively small (about 1.5 larger than 22800) patrol ships with relatively limited armament but good endurance, useful in a lot of peacetime operation which do not require massive firepower (in one occasion Russia had to use freaking peter the great battle cruiser for an anti pirate operation (for which often it uses instead udaloy class destroyers) as it was the only available ship with required endurance.

22800 are good small missile ships and with Pantsir, they have now even decent short to mid range anti air protection.

I would actually gladly see a new small ship, maybe a variant of either 22160 or 22800, specialised in antisub warfare, a sort of modern replacement for the project 1124 grisha class.

All of those small ships can be also be built inland and can use the internal rivers/channels to move around the various seas (most 1124 were build in Zelenodolsk (Tatarstan) and Kiev (in addition to Khabarovsk and Vladivostok)).

Especially if we talk about black sea, large ships are not really needed there, except for the fact that ships from the black sea fleet can also serve in the permanent russian squadron in the med or temporarily cross over to red sea or Persian gulf.

By the way, are there water channels in Iran allowing a corvette like 22800 or 22160 to go from the Caspian sea to the Persian gulf?

The terms of repair of the frigate of the Black Sea Fleet (BSF) "Admiral Grigorovich" will be determined after the completion of dock inspection and fault detection. A source in the shipbuilding industry told TASS about this.

“The approximate duration of the repair of the Admiral Grigorovich frigate will become known in 10 days after the dock inspection of the ship is completed,” the agency’s interlocutor said.

TASS emphasizes that it does not have official confirmation of this information.

The frigate "Admiral Grigorovich" project 11356R was launched in 2014. The ships of this project are designed to combat submarines and surface ships, as well as repel attacks by air attack weapons. The frigate received eight cells of the 3S14 universal ship firing system, which allows launching Kalibr-NK or Onyx missiles.

In May, TASS, citing a source in the shipbuilding industry, reported that the Admiral Grigorovich had arrived in Baltiysk for scheduled repairs, which would be carried out at the Yantar Baltic Shipyard. The ship arrived after a watch in the Mediterranean.
