Russia developing Shtorm supercarrier

Russia's Krylovsky State Research Center (KRSC) has developed a new multipurpose heavy aircraft carrier design called Project 23000E or Shtorm (Storm).

A scale model of the ship is going to be demonstrated for the first time at the International Maritime Defence Show 2015 in St Petersburg from 1-5 July, Valery Polyakov, the deputy director of KSC, told IHS Jane's .

"The Project 23000E multipurpose aircraft carrier is designed to conduct operations in remote and oceanic areas, engage land-based and sea-borne enemy targets, ensure the operational stability of naval forces, protect landing troops, and provide the anti-aircraft defence," Polyakov said.

The design has a displacement of 90-100,000 tons, is 330 m in length, 40 m wide, and has a draft of 11 m. It has a top speed of 30 kt, cruising speed of 20 kt, a 120-day endurance, a crew of 4-5,000, and designed to withstand sea state 6-7. Currently it has been designed with a conventional power plant, although this could be replaced by a nuclear one, according to potential customers' requirements.

The ship carries a powerful air group of 80-90 deck-based aircraft for various combat missions. The model features a split air wing comprising navalised T-50 PAKFAs and MiG-29Ks, as well as jet-powered naval early warning aircraft, and Ka-27 naval helicopters.

The carrier's flight deck is of a dual design, features an angled flight deck, and four launching positions: two via ski-jump ramps and two via electromagnetic catapults. One set of arrestor gear is included in the design. The design also features two islands; a feature only previously seen on the latest UK design.

Protection against air threats will be provided by four anti-aircraft missile system combat modules. An anti-torpedo armament suite is available.

The electronic support complex includes integrated sensors, including a multifunction phased array radar, electronic warfare system, and communications suite.

Polyakov pointed out that these specifications are subject to change, correction, and modification during the ship's design and development at every stage of work, once potential customers come up with a demand to change the weapons package and equipment.

Ideje se množe, NII Krilova je moćna institucija, naravno da se prave skice, idejni projekti, moraju naučnici zarađivati platu, a poslednjih godina ona nije mala. Šta se trenutno može reći nesumnjivo i određeno? Ništa, sem da Rusija razmišlja o gradnji pravog i velikog NA. Propulzija bi sigurno bila atomska, jer ne postoje ni kotlovi ni turbine potrebne snage, a potrebno je 300.000ks, po 75.000 na osovinu, osovina 4. Konstruktivna zaštita - oklop, posebni uslovi za dejstva na Severu i mnogo, mnogo para. Rusija sada te pare nema, nema ni mnogo šta drugo.

Da ne otvaram novu temu, postaviću tekst o razvoju buduće generacije ruskih atomskih podmornica ovde.

Russia expects to complete detailed design work on its of its next-generation Project Husky-class submarine within two years. That’s what United Shipbuilding Corporation (USC) officials told the Moscow-based TASS news agency earlier this week. However, the TASS report did not cite its source by name or offer direct quote.

Nonetheless, there some details that have emerged about the projected Husky-class follow-on to the Project 885M Yasen-class boats. For one, the new boats will come in two versions—which are being developed by the Malakhit Design Bureau—that will be based on a common hull design.

The primary difference will be in the two vessels’ weapon systems—the “interceptor” variant will not feature tubes to carry long-range anti-ship or cruise missiles. That version of submarine is expected to replace Project 971 Shchuka-B (NATO: Akula), the Project 945 Sierra and the remaining Project 671RTM Shchuka-class (NATO: Victor III) boats. The SSGN variant will replace the Project 949A Antey-class. The SSGN variant will also be armed with hypersonic Zircon cruise missiles.

The Russians are using the Project 855M Yasen-class as a starting point, but the new submarines will be smaller and cheaper than their Soviet-designed predecessors. Indeed, there are indications that Moscow will be extensively leveraging automation technologies developed for the Project 705 Lira-class attack submarine—better known in the West as the Alfa-class—for the new boats.

Russian analysts estimate that the next-generation submarines will displace no more than about 6,000-tons. Which means that another Soviet innovation might make a comeback—liquid metal cooled reactors. The Lira and several other Soviet designs used lead-bismuth cooled reactors, which produce much more power and are much more compact than pressurized water reactors. However, the disadvantage is that liquid-metal cooled reactors cannot be shut down and require specialized port facilities.

Russia will also incorporate composite structures in its next-generation follow-on to the Project 855M Yasen-class in the 2020s. The next-generation Russian nuclear submarines may use composite structures in an attempt to drastically reduce their acoustical signatures. But while the United States has used composite materials to reduce the weight, complexity and cost of parts for the Virginia-class submarine, the Russian efforts are far more ambitious. But this wouldn’t be the first time Moscow has experimented with novel materials to build submarines. Before its collapse, the Soviet Union pioneered the use of titanium hulls to increase the hydrodynamic performance of its boats.

“These are new multi-layer composite materials. . . . Their structure and composition reduce the sonar signals that are reflected from a submarine, isolate working mechanisms from vibrations, and so on,” said Valeriy Polovinkin, an adviser to the general director of the Krylov State Research Center, in an interview with the Russian-language daily Izvestia. “The opponent just will not get the required level of signal reflected from the submarine as the composite material has a high internal loss factor, or sound absorption properties can change when vibration occurs, completely preventing the spread of vibrational energy.”

The Russians hope to use composite materials for everything from the hull coating to the dive planes, rudders, stabilizers, propellers (or pumpjet propulsors), drive shafts and possibly even the hulls themselves. If the technology works, composite materials would greatly reduce the weight of various structures, increase the boat’s reliability and reduce operating costs. That’s because composites don’t corrode and thus wouldn’t need to be painted, Polovinkin said—reducing maintenance costs. Moreover, composite structures should simplify manufacturing by reducing part counts.

The new composite materials are still in testing, but Russia will test its first composite propeller design in 2018. “This is one of our institute’s most promising projects,” Polovinkin said. “This trend reduces vibration in the blades and increases the efficiency of the screw. These various effects will help improve the ship’s acoustic signature.”

Question as always with Moscow’s ambitious new projects is how Moscow hopes to pay for them even if Russia has the technical wherewithal to develop the technologies.
