Edit, the thing on top of the bow is as far as I know, the DUUX-5. The rest of your information is correct I think.

Info in the links in my first post suggest something else:

Design Features. The DUUX-5 Fenelon is an upgrade of the DUUX-2. It passively detects submarines at long ranges, making an active system necessary only for fire control. A set of six flat array panels are fitted three per side. Using at least two units per side, the submarine can determine a contact’s range by triangulation. Course and speed can be determined by TMA (Target Motion Analysis).

A sonar intercept unit records the bearing of all transmissions heard in the 2 kHz to 15 kHz band. It monitors noise near the submarine in 120-degree sectors on each side of the submarine. Four contacts can be tracked at once, one per 120-degree sector (on radiated self-noise) and one by the intercept unit (on sonar pulses).

LOFAR (Low Frequency Analysis and Ranging), DEMON (DEMOdulated Noise) and pulse analysis capabilities are included. The DUUX-5 system uses TSM-320C30, 68020 and 68040 processors for signals processing in MIM D-type hosts communicating internally across high-speed ring networks and externally on standard VME buses. The system software is programmed in C and Ada. A direct interface of target data with the submarine’s fire control system and plotting table is provided.

Operational Characteristics. The DUUX-5 Fenelon (TSM-2225) is one component of the TSM-2233 and TSM-2272 Eledone integrated sonar system. It may also be deployed as a stand-alone system with its own processing and operating facilities. A variety of intercept panels make it is easily adaptable to suit submarine size and program requirements. A second workstation can be added to extend target identification capability.

The system has high accuracy and discrimination char*acteristics, immunity against sonar pulse interference, simplified calibration, and integrated test facilities. In the middle sector the accuracy on bearing is, under normal conditions, 0.3 degrees, discrimination accuracy between two targets 2 degrees, and the range on radiated noise for a target at 10 kilometer distance, 5 percent.

Is the walrus class an ocean going meaning “blue water” SSK? What is its patrol endurance? Does it have proivisions for AIP?

Yes, the range is 10 000nm while snorchelling with speed 9 knots. No AIP so far installed onboard of Walrus class. See more info http://www.dutchsubmarines.com/

Italy, Russia Move Ahead on Joint Diesel Subs
By TOM KINGTON, ROME And LYUBOV PRONINA, MOSCOW

Russian and Italian firms are working up technical drawings for a new diesel submarine for the export market, even as they start scrapping some of their own older subs.

Fincantieri and Russian submarine-builder Rubin are in the second phase of developing a 1,000-ton conventional submarine, the S1000, which will be equipped with an Air Independent Propulsion (AIP) system said to be capable of staying underwater for 10 days. The project was launched by the Italian government in April 2004.

“Rubin presented a blueprint of the submarine to the Italian Defense Ministry six months ago and is now at the second stage, preparing the technical draft that should be ready by the end of next year,” said Yuri Kormilitsyn, chief designer of non-nuclear submarines at the Rubin Central Design Bureau, St. Petersburg.

It was too early to say when the sub might begin construction, Kormilitsyn said.

Fincantieri declined to comment on its progress, but has said the S1000 will be 40 to 50 meters long with a top speed of 14 knots, a crew of 16 and maximum depth of 250 meters. The S1000 will be designed for anti-submarine warfare, intelligence-surveillance-reconnaissance, and transporting up to 12 special forces troops. Other missions could include anti-surface warfare, mine-laying and air operations support.

An Italian industrial source said Fincantieri is developing a new fuel-cell-powered AIP system.

Rubin’s Kormilitsyn confirmed that Italy would provide the S1000’s AIP technology.

The Italian source said the AIP system would not be the same one that is going on two U-212-class subs, being built under license from Germany’s HDW by Fincantieri for delivery to the Italian Navy this decade.

“Part of Fincantieri’s agreement with the Germans is not to export that technology,” the Italian source said.

But other technology is intended to flow between the two partners in the new sub. “We are teaching but also learning,” said the Italian source.

“We are interested in Western technology and could share some of the technologies that we have,” Kormilitsyn added.

He said the new sub would combine Russian work on the Amur 950 submarine and Italy’s experience with the U-212.

The S1000 is Rubin’s first tie-up with a Western firm, Kormilitsyn said, but the firm also is seeking deals with other European submarine builders.

“There is an integration between Russia and NATO, and Italy took up the flag,” he said. “We have given our proposals to Germany and France, but negotiations have been slow.”

Neither the Russian or the Italian navies appear likely to order the S1000 in the near future.

“Our own Lada-class submarine covers the demand for the domestic navy,” Kormilitsyn said. The Russian Navy is satisfied with the fourth-generation Project 677 sub, a 1,600-ton diesel-electric known as the Project 1650 Amur for export, he said.

And Italy had planned to buy four U-212s, but budget cuts have restricted the order to two. So Fincantieri has its eye on exports. And like the Russians, it also has considered tie-ups with Germany. In an article about the S1000 in its in-house journal in September 2004, the firm wrote that it had previously sought and failed to sign a development deal with HDW.

“Cooperation with Russia is therefore an alternative opportunity,” the article said. “Apart from having relevant know-how regarding development and products, Russia still has an undeniable political and commercial influence in various areas of the international market (Asia, the Arabian Gulf and southeast Asia) … The cooperation must aim at this market with modern, medium-sized — and therefore less expensive — products, in which a mix of innovation and modern Western technology can improve the chance of success in an important niche.”

How To Dismantle Atomic Subs

As Italy and Russia mull new subs, Italian firms are now separately engaged in dismantling retired Soviet nuclear subs. Italian firms including Fincantieri and Finmeccanica have started work worth up to 50 million euros ($58.5 million) to dismantle nuclear submarines, part of a 2003 Italo-Russian agreement.

Antonio Gozzi, chief executive of Italian steel firm Duferco, said Dec. 2 on the sidelines of a Russia-Italy business forum in Moscow that Duferco, along with four other Italian companies including Finmeccanica and Fincantieri, are helping Russia to dismantle submarines on the Kola Peninsula.

He said Italy is on track to dismantle 12 to 13 Russian submarines, with a first tranche of work worth 40 million to 50 million euros under way.

The work stems from a G-8 commitment to help Russia dismantle its nuclear arsenal. In 2003, Italy agreed to spend 360 million euros to work on nuclear subs and organize the safe burying of radioactive materials.

Italy is seeking to bury old Italian nuclear waste alongside Soviet sub waste, Italian newspaper Il Sole 24 Ore reported Dec. 11.

Many thanks Dan. 😀

Anyway I tried to translate it with lingo, but some parts are quite hard to understand. 😡

COuld anybody who knows french help me fith this? Anybody who knowns fe

· groupements de guidage (télépointeurs TRE) comprenant chacun:
– un radar de poursuite DRBR 51 avec une antenne AME1. Ce radar localise simultanément le but et deux missiles téléguidés.
– une antenne AME2 qui sert au déclenchement du répondeur et à la télécommande des missiles téléguidés.
– une antenne de ralliement Argus (ACE2) pour les missiles téléguidés.
– deux caméras de télévision (une par rail).

· des installations de stockage et de maintenance (dites “missilerie” en 1972) comprenant une soute principale où missiles et accélérateurs sont stockés sur 2 barillets horizontaux contenant 18 missiles (dans la chambre-relais) plus des missiles de réserve en soute.

and this part is really hard for me:

Tel est en effet le nom officiel des engins que l’on tire contre les aéronefs ennemis,et qui se composent de deux parties, l’accélérateur à l’arrière, et le missile proprement dit, à l’avant, reliés par une menotte explosive.

Chaque composite arrive de la Pyrotechnie en pièces détachées : deux conteneurs contiennent l’un l’accélérateur, l’autre le missile, gouvernes repliées, tous deux tenus par des cadres, tandis que la menotte et les quatre empennages sont dans deux caisses séparées.

L’opération consiste à aller prendre l’accélérateur dans son conteneur, grâce à un palonnier manoeuvré par une grue, à le placer sur un ascenseur situé à tribord arrière du pont teugue, et à le descendre ainsi dans le local de contrôle MASURCA sur le pont inférieur. La gare de triage qu’est ce local permet alors de placer l’accélérateur sur l’un ou l’autre des chariots à crémail*lère qui l’emmènera s’accrocher par ses deux patins sur la partie arrière de rail de refoulement adéquat

Ensuite, on embarque de la même façon le missile lui-même, et le chariot qui l’emmène permet de le hisser manuellement dans l’axe de son accélérateur, sous le rail. Il faut bien prendre garde de ne pas cogner la coiffe en céramique qui protège l’autodirecteur à l’avant, de ne pas endommager les gouvernes en aggloméré, et éviter soigneusement tout mouvement brusque pouvant occasionner un choc. Qu’on ose donc encore parler de la brutalité des canonniers!

Il faut ensuite procéder à l’assemblage, opération la plus délicate, en vérifiant que las numéros des morceaux sont bien ceux qui vont ensemble. Après avoir branché les deux prises de jonction entre accélérateur et missile, on emboîte ce dernier dans le premier, on place les deux moitiés de la menotte explosive, on la serre avec une clef dynamométrique pour obtenir un entrefer de cinq dixièmes de millimètres dans le système de mise à feu.

Le composite complet est donc suspendu au rail par les deux patins de l’accélérateur ; il ne reste plus qu’à le descendre sur un berceau vide du barillet correspondant, et à embarquer les empennages de l’accélérateur, eux aussi numérotés et adaptés à chaque engin.

anyway this pic is cool 😎

Pave Penny doesn’t allow for targeting. It’s a marked target seeker only.

Sure I know 😉 .
Use of Pave Penny is the simplest way to provide guiding LGBs on the target without use of other expensive pods(as on A-10 on your pic). Of course it is limited with need of external source designator.

Anyway, nobody has some pic or drawning of such configured Kfir?
