This is Confirmed AESA......Thank You

Any information in which band it operates X ,L or S ?

Pretty much, yes. Hexagonal subarrays in this geometry favor the "AESA" hypothesis.

The mandatory L-band array is visible at the top.

The main array should be X-band.

Yes to me this looks like AESA Array , what is written in Russian any idea ?

X band would be interesting , Most of the Array I know like the Indo-Israel AESA EL/L-2248 is an S band Array.

Latest US Dual Band AESA on Zamwult is L/X band I think.

I was expecting the new AESA from Russia to be L band to take care of Range and Detection of Target with Low RCS , X band would mean they are more designed for Higher Resolution of Targets along with Fire Control solution.

Any idea what is the Top Most Radar which rotates , Any details ?

I don't really have any idea.

L-band plays an important IFF role; we are, of course, talking about 3D IFF here.

Austin wrote:Any idea what is the Top Most Radar which rotates , Any details ?

Its designation is 5P-27, Furke-4. Its main array should be an S-band 3D ESA with additional mechanical rotation. Whether it is "AESA", "PESA", or something else, I don't know.

Among domestic developments are embedded developed in STC "Altair" the ship's antenna modern complex AWGB.
They are assembled in a modular fashion to force all-metal chassis and installed directly into the superstructure in the ship,
forming a single mechanical system "superstructure - the antenna."

Used translator, was to lazy to do it myself.

Austin,

Based on the translation, they are almost certainly "AESAs".

Nothing in the texts indicates that they are AESAs, actually.

I am curious why you guys think they are AESAs at all, based on these several graphics.

It talks about modularity; it shows modularity. With respect to a "PESA" array, you never emphasize whatever limited modularity that a "PESA" can be attributed with.

To me the hexagonal geometry indicating each T/R module in the diagram is a give away.

In PESA you wont see such a thing as they have TWT with just a front plate to scan not individual T/R module

Each hexagonal module would consist of many T/R channels/modules (smaller modules, or sub-modules).

The Puma family has a similar modular "AESA" array too. For example, the smaller Puma on proekt 20380 has 24 T/R modules, each consisting of many T/R channels/modules (again, smaller modules, or sub-modules).

New advanced frigate set afloat in Russia

Project 22350 frigates are armed with 16 Onyx and Kalibr missiles as well as the Poliment-Redut air defense missile system

MOSCOW, December 12. /TASS/. The second Project 22350 frigate, the Admiral Kasatonov, was set afloat at the Northern Wharf in Russia's northern capital of St. Petersburg in the presence of Russia’s Navy Chief Commander Admiral Viktor Chirkov.

“We set afloat a second Project 22350 warship designed for remote sea areas to ensure Russian national interests in any part of oceans in the world. This warship has embodied all thoughts and ideas of our designers and requirements of our fleet,” Chirkov said.

He recalled that Admiral Gorshkov, the first warship of the project, is already at sea trials.

“I hope that the Northern Fleet will accept these warships with a great pleasure and responsibility, because they will be first who will operate first-rank warships destined for far sea areas,” the chief commander added.

Construction of Project 22350 frigates started in 2006, when lead ship of the project Admiral Gorshkov was laid down. This was reported earlier that it set out for sea trials for the first time in November. The warship can be taken for pilot operation in early 2015, a military source told TASS.

Admiral Kasatonov, second frigate of the project, was laid at the Northern Wharf in 2009, construction of Admiral Golovko started in early 2012. Meanwhile, one more warship of this type named Admiral Isakov is being built in St. Petersburg. It was laid down in autumn of the previous year.

Third Project 22350 frigate to be set afloat in late 2015

The third Project 22350 frigate named Admiral Golovko will be set afloat at the end of the next year, Northern Wharf acting head Yuri Taratonov said on Friday.

“We should set afloat three, five and more warships every year,” Taratonov said, noting that a third warship of this project would be built at the end of the next year.

Project 22350 frigates displace 4.5 thousand tons and can speed at 29 knots (53.7 kph). In particular, these vessels are armed with 16 Onyx and Kalibr missiles as well as the Poliment-Redut air defense missile system.

Russian Navy to receive new modification of Project 22350 frigates — chief commander

MOSCOW, December 12. /TASS/. Russia’s Navy plans to receive more than 15 Project 22350 frigates and its Project 22350M modification, Navy’s Chief Commander Admiral Viktor Chirkov told reporters on Friday.

“In the near future the Navy plans to receive more than 15 Project 22350 frigates and their Project 22350M modification. These warships will make backbones of naval groupings in the Arctic Region, the Atlantic and the Mediterranean Sea,” Chirkov said.

Im eager to found out what will those empty spaces lying by the UKSK launchers be used for as well as those on the stern.

I am quite sure they will not be used for weapons.

Also:
“In the near future the Navy plans to receive more than 15 Project 22350 frigates and their Project 22350M modification."

Interesting definition of near, that mister Chirkov has.

Project 22350M modification will have any difference in armaments?

Admiral Kasatonov put in the water.

Look carefully - it makes sense

Is this the 22350M project?

It seems the 22350M will not differ in weapons, but mainly in electronics.

I was comparing Admiral Gorshkov to the Halifax class frigate yesterday and I was surprised when I saw that Halifax class has almost twice the range of Gorshkov (Gorshkov = 4500 nmi vs Halifax = 9500 nmi). any explanation for this?

I know wikipedia is not the best of sources but these figures must be based somewhere

The Hali's most likely carry more fuel as they lack any serious (and large) armament.

Wikipedia is, of course, wrong.
