Came across this on a vietnamese forum: Talwar model with 3×12 cell VLU in place of current 24 round SRL.
See also here, for another model of a derivative: http://archive.kaskus.us/thread/1112360
Okay… those pics help put it in perspective. But the similarity is fairly slight. It’s not the same as that between the old Krivaks and Talwar; aside from the lower part of the hull and the positioning of some superstructure elements the two designs have very different shapes.
With all that space only six Rif-Ms is a real waste.
Balony! All key superstructure characteristics are the same. The twin hangars are identical, for example. As is the lay out of the stacks (because it uses the same powerplant. The modification is reminiscent not only of the mode from Krivak III to Talwar, but also of the kind of (Servernoye helped) modifications of the Delhi (P15) design to turn it into the Kolkata (P15A).
project 11550
project 21956
Severnoye has produced several other proposals for modified Udaloy I/II, of which 21956 is perhaps the most comprehensive modification. Here’s an example (note how the decks are beginning to get more enclosed):
I was fairly sure both active and passive radar could be installed on the same ship. That’s how it is with the Garpun-B, anyway.
It is not 2 radars but a single radar that can operate actively (i.e. emit and receive) as well as passively (receive only, with another radar elsewhere – friebdly or otherwise – acting as emittor). In that sense, it is no different from dedicated ESM gear, except that it is integrated into a radar system.
From your own source:
Composition
• active radar channel
• passive radar channel
• equipment used by both channels (multiband dish antenna, control panels, power management unit, antenna hydraulic drive, high-frequency channels, and offset antenna)The radar makes coordinated use of active and passive channels to acquire and designate targets. It boasts increased operational range thanks to employment of high-energy active channel, advanced methods of signal generation and complex modulated signal processing, coupled with passive channel data, and requirements of covert operation, in severe ECM and sea clutter conditions.
The active channel uses a multiprocessor system to generate probing signals and radar data. It is integrated with a multi-computer secondary data processing, control and display network.
The passive channel performs hardware/software-based analysis and classification of incoming radar signals by comparing their parameters with those available in the database (up to 1,000 entries).
Mineral-ME shipborne radar system is intended to control missile armament system and provide over-the-horizon early radar acquisition and target designation on virtually all types of ships.
The system comprises:
– Mineral-ME1 active radar (ARdr),
– Mineral-ME2 passive radar (PRdr),
– Mineral-МЕЗ data exchange and orientation radar (DEORdr).
All radars are built around a single design base

It still is like ESM integrated into a weapons targeting radar: someone else will do the active bit.
I didn’t know that. Where did you read it? The 21956 design is over 1000 tonnes heavier thanthe Udaloys and has an almost completely different weapon and sensor suite.
But yes, it’s likely that whatever new destroyer the Russian navy decides on will look nothing like the 21956. It’s based on older systems like the Fregat radar and S-300FM SAM whereas any new destroyer will likely leverage the new systems developed for the Admiral Gorshkov frigates.

Agreed.
But the RSAF and other Asian E2 operators used it as an AEW. So it is relevant to them.
All I’m saying is that an enhanced E-2 derivative with an APY-9 radar and C3 capabilities on a different aircraft platform would have been another contender.:rolleyes:
The Israeli Air Force has purchased 3 Gulfstream G550 aircraft to serve as the new IDF platform for its new generation of AEW systems.[4] The system is called Eitam. Extensive modifications made to the Gulfstream’s fuselage, such as the addition of protruding composite radomes, are intended to allow for the housing of the radar arrays. In 2007, 4 similar G550-Phalcon aircraft were also purchased by the Republic of Singapore Air Force, to eventually replace its upgraded E-2C Hawkeyes. All 4 G550s are expected to be in-service by 2010
