The Fleet Admiral of the Soviet Union Kuznetsov, currently the only aircraft carrier serving as the flagship of the Russian Navy, will be upgraded, the media reported, quoting Navy sources. The aircraft carrier, due to enter a dry dock in 2012, will be re-launched in 2017.
Originally laid as the Leonid Brezhnev in 1982, launched as the Riga in 1985 and renamed as the Tbilisi in 1987, the warship received her current name in 1990. Western analysts call her a ship of a thousand names.
The Admiral Kuznetsov entered service with the Russian Navy in 1991 and was used for the operation of deck aircraft, the development of new tactics, including those for dealing with carriers of theoretical enemies.
In the late 1990s and the early 2000s, it was repeatedly proposed that the Admiral Kuznetsov, which remained moored for long time periods, be decommissioned and sold for scrap.
However, an improved situation in the country gave the ship a new lease of life. Her propulsion unit and other equipment were repaired, and she started taking part in various high seas war games more often.
In the mid-2000s, Navy representatives and Russian political leaders once again started speaking of the need to build aircraft carriers for the Navy. Moscow decided to preserve the Admiral Kuznetsov, used to train deck aircraft pilots.
The upcoming large-scale modernization was motivated by the need to eliminate the ship's inherent drawbacks and to repair some of her units. Plans for docking the ship in 2010-2012 were discussed more frequently and have now been confirmed.
Although it is hard to assess the revamped carrier's specifications, her future appearance can be predicted on the basis of available reports.
First of all, the defective propulsion unit comprising steam turbines and turbo-pressurized boilers will be replaced either with a gas-turbine or nuclear propulsion unit.
The ship's 3M45 P-700 Granit (SS-N-19 Shipwreck) anti-ship cruise-missile launchers will be dismantled, and her internal layout changed. Consequently, the hangar area will be expanded to 4,500-5,000 sq. m. for storing additional fixed-wing aircraft.
The Admiral Kuznetsov's air defenses will be strengthened by replacing 3K95 Kinzhal (SA-N-9 Gauntlet) missiles with a multi-role naval system featuring 80-120 new-generation and medium-range surface-to-air missiles (SAMs).
Moreover, 4-6 Pantsir-S1 (SA-22 Greyhound) combined short to medium-range SAM and anti-aircraft artillery weapons systems will be installed.
The new weapons systems will feature state-of-the-art radio-electronic equipment, probably including the standard Sigma combat information and control system, due to be installed on all new generation Russian warships. The system facilitates unprecedentedly effective cooperation between task force elements.
The carrier will also receive aircraft catapults, a logical option. Considering the fact that her ski-jump will remain intact, one or two catapults can be located on the angled flight deck.
A similar engineering solution was envisioned for the incomplete Ulyanovsk super-carrier, whose keel was laid down in 1988, but the project was cancelled when it was 40% complete along with a sister ship in 1991 after the end of the Cold War.
By that time, the Soviet Union had developed steam catapults and tested an experimental version at the ground-based NITKA training facility incorporating a ski-jump and deck arrestor. Consequently, this task is feasible.
The choice of catapults is linked with the choice of the ship's propulsion unit. Steam catapults require a nuclear propulsion unit, while a gas turbine propulsion unit leaves no choice but electromagnetic catapults. Moscow will either have to develop such catapults independently or buy them abroad, or ... copy them illegally.
The carrier's air wing is to comprise 26 new Mikoyan-Gurevich MiG-29K Fulcrum-D multi-role fighter aircraft, helicopters and navalized Sukhoi T-50 PAK FA (Future Frontline Aircraft System) fifth-generation fighters, currently under development. It appears that 15-20 of these aircraft will be built pending the ship's re-launching, which is likely to take place in 2020 rather than 2017.

Le nouveau sous-marin russe multirôles
20/04/2010
La marine russe réceptionnera-t-elle en mai prochain le Severodvinsk (K-329), nouveau sous-marin nucléaire d’attaque (SNA) de type Yasen/ Graney (Project 885) ?
Des problèmes techniques, récemment survenus, pourraient repousser l’échéance. Quoi qu’il en soit, le Severodvinsk, dont les essais devraient, en principe, débuter dès l’été et qui pourrait être admis au service actif dès 2011, constitue le premier sous-marin atomique construit durant la période post-soviétique par JSC Sevmash. Les ingénieurs et officiels russes ne tarissent pas d’éloges sur ce bâtiment, présenté comme plus silencieux que les Akula améliorés (Project 971 Schuka-B) et régulièrement comparé aux Sea Wolf de l’US Navy.
Doté d’une double coque, ce submersible à dix compartiments apparaît d’ores et déjà novateur en terme de design, puisqu’il est doté de huit lanceurs verticaux à trois missiles situés derrière le kiosque. Des tubes permettant l’emport de 24 missiles SS-N-26 (3M55 Onix/Yakhont) capables de frapper des cibles situées à 300 km. Ces missiles sont notamment dotés d’un système électro-optique de reconnaissance de silhouette. Les moyens offensifs s’appuient également sur huit ou dix tubes lance-torpilles, permettant la mise en œuvre de systèmes VA-111 Schval ou du missile antinavire SS-N-16. Les senseurs du sous-marin, dont la construction a subi bien des aléas depuis son lancement en 1993 (la construction a notamment été stoppée en 1996 pour des raisons financières), constituent également un bond qualitatif pour la marine russe.
Les Project 885 seront, en particulier, dotés du premier sonar sphérique Irtysh Amfora (similaire à celui des SNLE Borei), dont le volume a contraint les ingénieurs à reculer l’emplacement des tubes lance-torpilles. Le Severodvinsk doit, en outre, être équipé des moyens acoustiques VLF de coque et d’un sonar tracté.
Mis en œuvre par un équipage de 50 hommes et jaugeant 8 000 à 9 000 tonnes (12 000 à 13 000 en plongée) pour 115 mètres, selon les évaluations occidentales, le sous-marin serait muni d’un réacteur type OK-650KPM à eau pressurisée de 200 MW, permettant d’atteindre 31 à 35 nœuds en plongée.
Un second bâtiment, le Kazan, est d’ores et déjà en chantier sous la dénomination de Yasen-M et devrait bénéficier d’améliorations substantielles par rapport au Severodvinsk. Si, initialement, Moscou tablait sur la production d’une trentaine de submersibles, l’objectif vise désormais la mise en service de six ou sept unités.
Le Yasen constitue un lointain parent des SNA Akula (Project 971), tout en disposant de capacités de frappes à longue portée similaires aux Oscar II. Ces derniers sont désignés par la marine russe comme «croiseurs sous-marins lance-missile de premier rang» (Atomnie Podvodnie Kreysery 1 Ranga – APKR) et non comme «SNA» (Podvodnaya Lodka Atomnaya - PLA). Moscou pourrait proposer le Yasen à la marine indienne, à l’issue de son expérience avec le Nerpa (INS Chakra). Dans le contexte de refonte des moyens et de la doctrine sous-marine russe, les Project 885 devraient venir remplacer le dernier Sierra (Project 945A) opérationnel, puis progressivement les cinq ou six 949A Antei (Oscar II) encore en service.
Une relève qui permettrait à la marine russe de ne conserver, avec les Akula II, que deux types de SNA. S’ils remplaçaient les Oscar II, les Yasen seraient chargés des missions de chasse de groupes aéronavals ennemis. Selon certaines sources, Moscou pourrait cependant choisir de préserver la polyvalence opérationnelle offerte par les Yasen et prolonger les Oscar-II en service actif jusqu’en 2025, d’autant plus que trois submersibles de ce type restent actuellement inachevés dans les chantiers navals russes.

Aunque sea la versión "normal" es un muy buen submarino. Que yo sepa USA les tiene un merecido respeto.






Russia's ready to bring back cruiser Ukraina
Russia is ready to buy incomplete battle cruiser from Ukraine, MP Mikhail Nenashev, member of defense committee said during teleconference "Moscow-Kiev".
"The well-known agreement recently signed by the presidents [Dmitry Medvedev and Viktor Yanukovich] in Kharkov as for prolongation of Black Sea Fleet deployment in Crimea, is primarily an economically sound for both countries… I mean new opportunities to cooperate in shipbuilding; and this implies not only repairs but joint building of ships… Example, a known cruiser [Ukraina] similar to missile cruisers Moskva or Ustinov is standing idle in Nikolayev 70% completed. Of course, this ship could be commissioned into Russia's Black Sea Fleet, we need such ships", said Russian MP.
Such agreements "evoke negotiations on this matter", pointed out Nenashev.
Meanwhile, the issue of French heli-carrier Mistral is still doubtful, said the official. "Speaking of Mistral, it is still unclear whether Russia's going to buy this ship", he said.
Recall that missile cruiser Ukraina is a warship of Ukrainian Navy. The cruiser was built at 61 Kommunara Shipyard in Nikolayev.
The cruiser was launched on Aug 11, 1990. On Oct 1, 1993 being 75% completed the ship was decommissioned from Russian Navy and passed into the ownership of Ukraine. In 1994 even the cruiser's crew was formed, although the ship was not completed due to lack of financing.
