c'est crédible le déplacement de +10000t?? qu'en est il de l’armement ? s'agit il de destroyer ou de croiseur  de défense aérienne ou l'équivalent chinois du zumwalt américain ??  quelle est l'origine de la propulsion ? est ce que l'industrie chinoise est capable de concevoir et de produire des turbines navales ?

1) Oui, va sur Google Earth aux coordonnées 30°25'14.97"N 114°15'44.29"E, et tu compares la taille par rapport à un Type 052D de classe 6 000 t

2) Classique, voir Type 052D

3) Destroyer, dans la classification chinoise

4) COGAG chinois

5) Oui

reste à savoir s'ils comptent  le produire en grand nombre ou s'ils  se contentent de petites séries..sinon je verrai bien des capacités anti balistique (à la SM 3 de l'us navy ) mais bon ça reste juste une supposition .

L'armée est au service de l'intérêt stratégie et l'intérêt économique d'un pays, il en va du même pour la Chine.

A partir du moment tu comprends où se situent les intérêts de la Chine ainsi que le volume associé, tu comprendras quasi-immédiatement le nombre approximatif de bâtiments qu'ils vont produire.

Pourquoi il y en a qui croit encore à l'arme suprême, comme si un seul vecteur suffit pour  changer l'équilibre militaire entre 2 pays... Encore si on parle du Rafale je n'ai rien à dire, parce que c'est connu mondialement comme l'étoile de la mort, mais là, on ne parle que le Type 055...

Qui plus est, l'auteur est un professeur dans CMSI (China Maritime Studies Institute) de l'U.S. Naval War College, mais où va-t-on... ??

Can China's 'Dreadnought' Tip the Naval Balance?

Lyle J. Goldstein


March 19, 2016

As the U.S.-China naval rivalry unfolds across the Asia-Pacific, Washington sails with significant confidence through these turbulent waters. After all, the U.S. Navy still far exceeds the Chinese Navy in gross tonnage, retains the advantage in key domains such as submarine quieting, has a huge network of bases, and possesses loyal, highly motivated and strong allies to boot. Still, as this Dragon Eye column has pointed out in several instances, Beijing also has some reasons for confidence in this nascent rivalry.

With respect to the territorial disputes on China’s maritime flank, the People’s Liberation Army (PLA) has an enviable level of strategic focus, but far and away its most important advantage is its favorable geography. That is to say that Chinese military planners enjoy the potent benefit of interior lines in almost any conceivable military scenario versus the United States. “Interior lines” is just a fancy way of saying that China can bring much more firepower to the fight much faster than the United States, at least in the initial phases of any military contest.

For these basic reasons, Western defense analysts should avoid being dismissive of emergent Chinese naval capabilities, even if the Chinese navy remains smaller and less experienced. It seems likely, moreover, that Beijing has indeed stepped up the pace of its naval building program, perhaps in part as a strategy to keep its shipyards humming at a time of contracting commercial orders. Indeed, Chinese shipyards do tend to build commercial and military vessels side by side in the same yard—a rather different model than the one employed by Western shipbuilders.

Just over a decade ago, Western naval analysts (including this one) marveled over the PLAN’s new “Red Aegis” Type 052C destroyer, the first Chinese warship to wield both phased array radars and vertical launch systems (VLS). Today, an improved variant of that ship, Type 052D, is in serial production, predicted to run to between eight and twelve hulls. This Dragon Eye will not focus on that impressive vessel, but rather will peer into the future and look at the ominous “dreadnought” on the horizon, China’s Type 055 cruiser, which is currently in development.

Some further hints about the mysterious behemoth, suggested as 11,500 tons fully loaded, were revealed in the Chinese magazine Shipborne Weaponry (舰载武器), published by a Zhengzhou institute of the China Shipbuilding Industry Corporation (CSIC). According to this description, which includes several rather detailed line drawings, the ship is projected to be 175 meters in length and twenty-one meters wide, with a draft of 6.5 meters and a top speed of thirty-two knots. The ship will wield four types of “new-type” (新型) missiles (discussed below), but that arsenal does not even account for the “long-range land attack cruise missile” (远程对地巡航导弹) and “sea-based missile interceptor” (海基反导导弹). In addition to electric drive propulsion, this analysis boasts that the the all-important phased array radars have been upgraded to include both X-band and S-band arrays—and thus may be on part with America’s top air-defense ships. This analysis holds that 055’s larger displacement will enable “larger weapons magazines and enhanced combat potential, so that its distant seas comprehensive fighting power will be much stronger” than its predecessors.

The article states directly both that Type 052C and D destroyers were constrained in their size by propulsion issues, and that engines for large surface vessels have formed a major technical bottleneck for the Chinese Navy. An interim step in the development process was the “indigenization” (国产化) of the Ukrainian GT25000 that resulted in the apparently “stable, reliable … [and] fuel-efficient” Chinese QC-280 gas turbine engine. Speed, acoustic and efficiency gains from electric propulsion are noted and the analysis goes on to claim that a major research “breakthrough” on this technology was accomplished by Wuhan shipbuilding research institute 712, so that by 2012, electric drive was already being incorporated into various Chinese prototype vessels, including non-naval platforms.

However, it is not really a possible propulsion innovation that makes this ship especially interesting. Obviously, the sensors (radars) deliver the ship’s core competence. Like the Aegis-equipped destroyers that formed the model for its predecessors, Type 055’s main mission is still certain to be fleet air defense, including for Beijing’s nascent carrier battle groups. The phased array radars on the Type 052D are said to be 15 percent larger and less rounded than 052C, delivering detection ranges not less than four hundred kilometers. Dual band radar technology, the article explains, was pioneered in the United States during the 1990s and originally planned for installation aboard the Ford-class aircraft carrier, as well as the recently unveiled DDG-1000. However, DDG-1000 did not get the system because of cost constraints, according to the Chinese analysis. Visible in the given diagrams of Type 055 are both the S-band radar (under the bridge and facing forward) and also the X-band arrays that are somewhat smaller and located in the middle of the large mast, but this may not constitute a genuine “dual-band” capability as the radars are not combined. Notably, the same drawings show a very prominent “fixed long-range warning radar” (固态远程警戒雷达) mounted above the helicopter hangar near the stern. The article claims that any further deficiencies with respect to radar are related to cost savings, and that China “will not confront a gap in radar capabilities or function.”

As to weaponry, the Type 055’s large cruiser dimensions are said to allow for ninety-six VLS launchers, up from sixty-four on the 052D destroyer now in production. Its large size allows not only for more weapons, but also for larger-dimension missiles, as this analysis states explicitly that a drawback of the current 052D VLS is that it cannot accommodate missiles longer than seven meters. In addition to the “long-range land attack cruise missile” and “missile interceptor” mentioned at the outset of this article, the other weapons that will likely be loaded into these VLS tubes, include a “new-type medium-range air defense missile” (新型中程舰空导弹), a “new-type medium-range antisubmarine missile” (新型中程反潜导弹), a “new-type long-range air defense missile” (新型远程舰空导弹) and “a new-type supersonic long-range antiship missile” (新型超音速远程反舰导弹). Interestingly, among the mission areas mentioned for Type 055 beyond air defense is not only missile defense, but also “antisatellite” (反卫星) operations. For close-in air defense, the ship is said to be upgraded with a new close-in weapons system (CIWS) that fires 9,600 rounds per minute—twice the rate of the former Chinese CIWS. Another interesting feature of the large design, of course, is the relatively expansive helicopter hangar. However, the helicopters illustrated in the design drawings feature the Ka-28 (an import from Russia) as well as the new Z-20 (a Chinese copy of the SH-60 now in development that I have written about in another Dragon Eye column), but not the larger Z-18AF that some had expected to see. However, one weapon that the Chinese analysis cautions will all but certainly not appear on Type 055 is an “electromagnetic gun” (电磁炮).

For readers following the progress of the U.S. Navy’s new cruiser DDG-1000, this last point may be read as an intentional dig by the Chinese side. Indeed, the DDG-1000 is notable for its new gun systems and has been described as optimized for supporting Marines fighting ashore with rapid, long-range gunfire. Pitting the projected Type 055 design against DDG-1000 may well be like comparing apples and oranges, to be sure, but as my colleague James Holmes has recently written in this forum: “The DDG-1000 will find itself sorely outranged by the missile-armed submarines, warplanes and surface combatants that comprise the core of naval fighting forces around the Eurasian perimeter. Chinese or Russian forces can blast away from beyond the reach of American guns or missiles.” Indeed, DDG-1000, together with the Littoral Combat Ship (LCS), currently lacks for suitable antiship cruise missile (ASCM) armament. Perhaps this explains why the USN is only building three of the DDG-1000. Chinese naval planners do not consider ASCMs as an afterthought in surface fleet development.

To be sure, many Western strategists will rightly note that Type 055 could be quite vulnerable to American and allied submarines. But if Beijing is investing in such large surface combatants, it suggests Chinese strategists are reasonably confident the Chinese Navy can protect them and, moreover, that these new “dreadnoughts” with Chinese characteristics could play a key role in the evolving naval balance in the Asia-Pacific.

Il y a 1 heure, DZIRI a dit :

Est ce que ces croiseurs auraient des capacités anti balistique ou un système sam très longue portée de la classe s 400 ou sm6 ?  

Pas à ma connaissance pour l'ABM, du moins pas pour le moment, mais il y a effectivement un missile ABM naval, le HQ-26, en développement depuis un bout de temps.

Il faut dire que la Chine n'a pas encore un besoin urgent de l'ABM qu'il doit être adressé à partir de la mer. Si on exclut les menaces ICBM qui ne sont pas interceptables à court terme, même pour les Américains, les seules menaces sérieuses sont celles de SRBM et de MRBM venant de l'Inde.

C'est pour ça la Chine développe en priorité les missiles ABM au sol et non à la mer, étant donné la situation géographique des deux pays.

Henri ,

Ce site parle de deux types de propulsions pour les 055 , laquelle est la bonne ?

https://thaimilitaryandasianregion.wordpress.com/2015/12/22/type-055-destroyer-china/

a) COGAG avec  4 TAG type QC-280 dérivée des UGT 25000 ukrainienne

707226055D2.png

b)  prop électrique avec TAGAlternateur QC-280  en production d’énergie et 2 Moteurs électriques en attaque directe ligne d’arbre que l’on aperçoit dans cette illustration

205032055D1.png

On en parle ici aussi

http://it15.net/2017/03/06/type-055-中国055型导弹驱逐舰/

, cf extrait google trad

« Sur son système d'alimentation pour la turbine à gaz comme le noyau de tout-électrique du système de propulsion, devrait être 4 QC-280 turbines à gaz, après des années d'efforts, le modèle est non seulement la technologie mature, la performance est également pas une petite amélioration, une seule puissance de 50.000 chevaux, 4 est une puissance de 200.000, assez pour permettre à des navires chargés de 12.000 tonnes, pour atteindre la vitesse de 30 noeuds. Le but principal de solutions de propulsion tout électrique pour l'installation ultérieure d'un nouveau concept de laser et d'autres armes fournies par commodité. »

http://www.globalsecurity.org/military/world/china/plan-propulsion.htm

 « La turbine à gaz QC280 / QD280 [GT25000] a résisté au test du golfe d'Aden pour escorter les opérations, montrant une performance fiable installée dans le destroyer de type 052B de 6.000 tonnes. L'imitation chinoise de la turbine à gaz GT25000 de l'Ukraine est évaluée à une puissance de 28 à 29 MW, mais la puissance de sortie réelle est d'environ 23 MW et quatre turbines à gaz GT25000 ont une puissance totale réelle d'environ 90 MW. La flotte de la marine chinoise dans le golfe d'Aden a mis en place une longue mission d'escorte, chaque groupe de navires a eu des performances à l'étranger pendant des mois et n'a jamais eu de problèmes moteur. Cela montrait que la fiabilité et l'économie de la turbine à gaz domestique GT25000 étaient adaptées aux besoins de la Chine. Le système d'alimentation basé sur le GT25000 pourrait continuer à améliorer sa technologie et les défauts de performance. »

Quand il y a deux choix pour la chinoiserie, j'ai tendance à m'orienter vers celui qui est le plus "réservé".

Donc je penche plutôt vers un COGAG. Le temps nous dira...
