Type 093 Nuclear Attack Submarine (SSN)

In the late 1990s it was reported that China had begun construction of its first Type 093 nuclear-powered attack submarine (SSN), after preparations in construction were detected by U.S. intelligence. The Type 093 SSN programme, which will replace the obsolete Type 091 (NATO codename: Han class) SSN, has been under development for more than a decade. Unconfirmed reports indicated that at least one Type 093 SSN boat has already been launched and is currently undergoing sea trials at an unknown location.

It appeared that China had encountered a range of technical difficulties in developing the Type 093 SSN, including nuclear radiation and noise reduction. It was reported that Russian assistance was sought to solve these critical issues in the late 1990s. The Type 093 SSN is expected to be similar in size and performance to Russian second-generation submarines such as Victor-III class. However, the Type 093 SSN would still represent a significant technological achievement comparing to the first generation Type 091.

It is estimated that the Type 093 SSN will be equipped with wire- and wave-homing torpedoes, submarine-launched anti-ship cruise missiles and mines. It may also be capable of firing anti-submarine warfare (ASW) missiles and land-attack cruise missiles (LACMs). The displacement of the boat is estimated to be between 6,500 and 7,000 tonnes, with a pressured water nuclear reactor and a single asymmetrical seven-blade skewed propeller.

According to some sources two Type 093 boats are planned, while other sources suggest that as many as six to eight are projected, with possibly four to six Type 093 submarines entering service by 2012. The extended re-fits to the Type 091 (Han class) suggests that there may be a delay in the development and building of the Type 093. U.S. intelligence has estimated that the first boat will be operational soon after 2005.

中国093型核潜艇已领先美核潜艇


作者: WorldKing-I R

  093型多用途核潜艇是中国于20世纪80年代开始研制的一型核潜艇。目前关于这型潜艇的传闻很多,另一艘094型核动力导弹潜艇的消息也很受人关注,目前只披露部分关于093型的消息。本文消息来源如下:1.部分即将解密
的内部资料,本文作者受托,恕不能公布消息正式来源,但据悉本消息肯定将在20个月之内解密。2.本文所列部分情况均悉转述原文,其具有相当准确度。

  研制过程一波三折 历经十余年仍徘徊不前

  70年代初期,中国研制的第一代鱼雷核潜艇研制成功,此后中国又研制了第一代导弹核潜艇,并于1985年首次水下试射弹道导弹成功。但是,中国研制的第一代核潜艇时,首先解决的是“有”与“没有”的问题。因此对于潜
艇的技术性能指标并无过多要求,80年代时这些潜艇就已经过时,例如092型导弹核潜艇只能发射射程2300千米的巨浪-1导弹,并且所有核潜艇均不适合过长时间的远洋航行。中国为了解决核潜艇的性能问题,一边先后对091和092进行了3次大规模的技术改进,一边开始研制中国的第二代核潜艇,即093和094。这其中,093是多用途核潜艇。

  093的最早研制设想早在1980年就已经出台。当时,邓小平在视察了海军潜艇部队时尤其提到了要大力发展核潜艇,并且要求“这个核潜艇的东西要走在其他军舰的前面”。海军于是于1980年11月下达了研制新型核潜艇的计
笔币笠锏角八樟谌募际跣阅苤副辍>甑姆锤绰壑ず土⑾睿093型于1983年7月正式上马。

  与当时中国的其他军品研制计划一样,093的研制也经历了风风雨雨,几经波折。最初093的研制进展非常缓慢,主要原因是无法解决新型武器和新型核反应堆的研制。1988年,中国核反应堆技术有突破性进展,并于当年向阿
尔及利亚和巴基斯坦出口了我国自行研制的民用轻水核反应堆。民用核技术的进展被国际上认为是中国在核技术领域中的一次很重要的跨越,当年的《简氏》曾专门刊文就中国核潜艇和核弹头的发展做出报道。

  1989年原先的093研制计划遭遇重大调整,原因是海军领导认为原先的093的有关性能已经不先进,为了避免出现091一出世就已经被淘汰的局面,有关部门对093的研制作出了调整。

  1993年093的研制再次受阻,原因仍然是技术的落后。当时美国新一代“弗吉尼亚”级(原名“百人队长”)核潜艇的研制进展非常顺利,1993年弗吉尼亚级的有关技术情报被PLA获取,有关技术性能领先当时的093至少两代以
稀U馊093的研制小组大吃一惊。

  海军对于093型的最初要求是,排水量在4000-6000吨之间,能够携带12枚战术导弹,可以发射533和650鱼雷,可以发射潜射导弹,达到国际 80年代水平。因此,093型的最初模型依稀可以看见前苏联阿库拉的影子。但是在很多关键领域如潜艇减噪,下潜深度和压水堆上,093的初期设计落后阿库拉级很多。而80年代前苏联S(塞拉)级更加先进,而美国海狼级则可以说
锏搅死湔狡诩涿浪蘸饲蓖а兄频募蕖

  此后093的研制趋于停滞,直到1996年我国新型核反应堆技术出现重大突破。原先的中国核潜艇均采用前苏联于6、70年代采用的压水堆方案,但是由于国内技术不过关,同时从国外引进又无可能,这导致核潜艇的研制无法有
所进展。中国为解决这一矛盾于80年代后期起另辟奚径,开始研制当时国际上最先进的高温气冷核反应堆技术。

  从此以后,093型的研制逐渐加速,直至现在。

  半途换项获得成功 动力系统世界领先

  高温气冷核反应堆最早在前苏联60年代就已经提出,其于60年代后期曾经专门就此技术展开讨论,当时得出的结论是“与其花大代价研制新型的有很大风险的高温气冷堆还不如继续研制压水堆”,确实,当时压水堆的技术还
有很大发展余地,而高温气冷核反应堆的理论最早于1964年3月见于前苏联核专家П Л 乌里扬诺夫提交的一份论文。但是在当时研制这样的新型反应堆确实有很大技术风险,主要瓶颈在于堆体对于材料的力学强度和堆内反应控制要求特别高,对堆内反应温度的掌握稍有不慎就会造成爆炸,发生与1986年前苏联切尔
诺贝利核电站相似的事故。前苏联虽然没有在60年代就这一项目上马,但是并没有放弃对这一技术的研究,每年都专门拨款进行相关研究,使得前苏联在这一领域的研究远远快于美国。80年代,在材料力学有了很大发展之后,前
苏联将研制高温气冷核反应堆列入正式计划。众所周知,在核潜艇领域,前苏联对于很多新技术的研制并不落后于美国。反观美国,一直到1981年才首次提出研究这一项目的计划,但是美国人对于这种技术并不十分关心,美国海
军认为以洛杉矶和海狼的先进程度,并不需要再在反应堆上再花大力气。前苏联对高温气冷堆的研制进展比较顺利, 1986年第一台模型出台。但是,就在其准备正式上马研制装备此堆的时候,苏联解体,接替苏联的俄罗斯一片萧条,俄海军不仅无法继续装备前苏联时期研制的比较先进的塞拉级,甚至连海军的官兵的工资都无法保证,更不用说
研制高温气冷堆这一需要国家大力投入的项目。此后它的研制就搁置了起来。

  本来美国是有机会接过前苏联的接力棒使用这一技术的。1993年,曾经获得过前苏联“二级功勋”奖章的Д 卡萨巴连科叛逃至美国,其携带有关于高温气冷堆的重要核心机密并期望以此获得美国籍。但是,美国这时刚刚在弗吉尼亚的研制取得很大进展,不太看得上卡萨巴连科的材料,况且卡萨巴连科本人生活比较放荡,到美国的时候
还吸毒,因此CIA认为此人情报疑点很多,导致美国没有重用此人。直到1998年美国获悉中国在这一方面研究取得重大突破再想起此人时,为时晚矣,卡萨巴连科已经在1994到1997年的某一年中因为吸毒与黑社会发生瓜葛,被枪

  中国研制这种技术始于80年代中期,苏联解体后中国大量引进前苏联技术人员,据悉,目前在西北进行军事研究的前苏联专家至少有6600人(对于这一数字的说法很多,普遍认为应该更多。因为90年代以后,中国因为外交和

材料力学和流体力学(1976年建设毛主席纪念堂时因国产玻璃钢硬度不过关而放弃采用的2号方案在1983年就已经解决)。中国的许多军品研制在90年代取得进展很大程度上归功于进口了大量俄国专家。

  1996年国产高温气冷核反应堆研制取得技术性突破,困饶多年的堆内温控问题基本解决。1997年底第一台高温气冷核反应堆样堆研制成功,并成功在四川试运转。此后中国先后数次拨专款加快093的研制。大约在2000年上半

  多年铸一剑 功到自然成

  随着反应堆的研制取得进展,093型的整体研制也上了一个台阶。从1995年开始,中国开始瞄准21世纪中国海军远洋作战需要重新设计093型。与美国的“前沿作战”需要不同,中国海军在21世纪的首要目标仍然是奔向大洋,
因此093的研制目标要求适于远洋深海作战。093的排水量和艇体大小被大大加大,同时配套武器的研究也同步发展。近年来海军在武器研制上有很大进展,如新型鱼雷,反舰导弹和巡航导弹等,实际上是为093准备的。093的最后
一项技术突破是2000年取得的消音瓦。

  目前的093型1997年开始艇体建造,1999年基本完成框架,2000年吊装反应堆,目前正处于最后的完工和全面调试阶段。估计093型可能在2001年上半年就已经下水,同时,由于相关技术基本成熟,093首艇的后续型也在施工

  正在设计建造中的094型也采用了大量093型的成熟技术。据悉,093型的反应堆、消音瓦、推进机的技术在世界上都是领先的。其中,使用高温气冷核反应堆的至少10年内将只有中国一家。

  值得注意的是,此次中国建造新舰艇一改过去先建首舰,经过反复调试再投入小批量生产的惯例。093型的后续艇几乎与首艇同时开工,只是在吊装反应堆时进度落后。中国此次如此快马加鞭一来迫于周边形势,二来更主要

髁耸匝椋泄 90年代新潜艇的研制速度并不快,很大程度上是为了保证093型的研究。

  美国军方对于093型的研制进度究竟掌握到何种程度尚不得而知,但是北约已经迫不及待地将其命名为“清”级。1997年时五角大楼曾经对外公布过他们掌握的093型研制情况,但当时美国人尚不了解在90年代中期093型的研
埔丫辛撕艽蟊涠8菸褰谴舐サ乃捣ǎ093型仍然采用压水堆。1999年美国人才知道中国的高温气冷核反应堆技术取得世界领先,并一度以为093型已经下水,这导致美国攻击俄罗斯向中国转让了核潜艇技术和当时的李文和

  中国军方对于093型的进展非常满意。根据海军的看法,这种潜艇的综合实力已经足以对抗洛杉矶改进型了,但在噪音、攻击范围和自动化上仍然较海狼和弗吉尼亚落后不少,但093具有的高航速和高潜深已经领先于这些美国
核潜艇。

  093型的噪音水平大约在105-110分贝之间,后续型号可能会有所改进。其优势在于航速,高温气冷核反应堆提供了强大的动力,093型的水下正常航速提高到35-45节,最大航速有可能突破50节,093正式出世后,将迅速正式打破前苏联47.1节的潜艇水下航速记录。

  093采用单双层混合排布的艇体,双层艇体为主。

PLA Navy Obtains New-Generation Submarines

PLA Navy Obtains New-Generation Submarines

Dr. Alexandr Nemets
Thursday, Nov. 21, 2002

In July 2001, in an article about PLA Navy modernization written jointly with Dr. Thomas Torda (PLA Navy: From 'Green Water' to 'Blue Water'), the author gave the most recent information available (from June-August 2001) regarding the "093 project" nuclear attack submarine:

By mid-2001, Huludao Military Shipbuilding Plant, in northeastern Liaoning province, finished construction of one submarine or, more probably, two submarines of this kind; this submarine (or these submarines) participated, in August 2001, in PLA's large-scale Dongshan maneuvers in the Taiwan Strait.

For about a year, no new information about the "093" project was available. Finally, several weeks ago the author got an opportunity to read the article "PLA missile forces" in the June 2002 issue of the Taipei-based journal Zhonggong Yanjiu (China Communism Research). The most interesting theses of the article are as follow:

* By 2000-2001, China, with heavy Russian assistance, finished developing and mastered production of HN(Hong Niao)-2 and HN-3 Land Attack Cruise Missiles (LACMS). All of them are capable of carrying nuclear warheads.

* The HN-2 series includes three varieties  namely, HN-2A and HN-2B for ground launching, with a range of 1,800 km, and HN-2C for submerged launching from submarines, with a 1,400-km range. According to reliable sources, HN-2Cs are installed on PLA Navy Song-class diesel-electric submarines; they could be vertically launched from standard 533-mm torpedo tubes.

* The HN-3 series, with a range of 2,500-3,000 km and maximal rate of 0.9 Mach (speed of sound), includes the HN-3A variety for ground launching and the HN-3B variety for submerged launching from the "093 project" nuclear attack submarine.

* China (no doubt with heavy assistance from Russia) is presently engaged in developing "super-advanced" LACM with a range of 4,000 km.

(end of Zhonggong Yanjiu theses)

According to data available, by the end of 2002 the PLA Navy commissioned five Song-class diesel-electric submarines (constructed at Wuhan Shipyard in Hubei province of Central China) and two "093 project" nuclear attack submarines. It looks as if all of them are equipped with long-range LACMs, mostly with nuclear warheads.

Let's be grateful to Russian cruise missile designers in Reutovo (an eastern suburb of Moscow), Dubna (a town about 150 km north of Moscow) and Yekaterinburg (a major city in the Ural zone), as well as to St. Petersburg-based Rubin Bureau, the major designer of Russian  and Chinese  nuclear and diesel-electric submarines.

They were initially supposed to construct the "093 project" submarine as an improved variety of the Soviet Victor III nuclear attack submarine equipped with the following major weapons:

* submerge-launched anti-ship cruise missile with a range of less than 100 km;

* anti-submarine missile with 40-km range.

It seems that the "093 project" equipped with HN-3B long-range LACMs is a greatly improved variety of Victor III.

Probably the PLA has no intention of constructing additional "093 project" submarines, which belong, in general, to the world level of the 1980s. However, in 2003-2005, the PLA would get several more Song-class submarines equipped  if the data of U.S., U.K. and Taiwanese military intelligence are reliable  with mid-range HN-2C LACMs.

By mid-2002, three major Russian shipyards  Severnaya Verf in St. Petersburg, SevMash plant in Severodvinsk (near Arkhangelsk city on the White Sea) and Komsomolsk-na-Amure Shipyard  started construction of eight units of the "super-Kilo 636" diesel-electricl submarine for PLAN needs. These submarines will be at least as noiseless as Victor III/"093 project." The major weapons of this upgraded submarine include:

* six tubes for 533-mm "standard" torpedoes;

* Club submerge-launched anti-ship cruise missile system with 200-km range;

* Shkval sophisticated torpedo system.

According to estimates of Russian experts, both Club and Shkval have no analogs among the world weapon systems of these classes. Probably the "super-Kilo 636" belongs to the world level of the second half of the 1990s and, by overall combat potential, surpasses Song-class submarine and doesn't yield greatly to the "093 project" submarine.

According to the initial contract, construction of the "super-Kilo 636" should be finished in 2006. However, some Hong Kong sources claim that (a) PLAN will get these eight submarines by 2005 and (B) Wuhan Shipyard, the major Chinese constructor of diesel-electric submarines, will obtain at the same time the "super-Kilo 636" manufacturing technology.

That's not all.

In the second half of 1999 to the first half 2000, there were a lot of messages regarding PLA Navy interest in purchasing Russian Akula-class "noiseless" submarines. However, PLAN interests in this area had shifted somewhat by 2002.

In December 2001, the Russian Navy commissioned its second (by other sources, first) "upgraded Akula" or Akula II-class nuclear attack Gepard. It is considered the most advanced in the Russian Navy inventory of nuclear attack submarines. Gepard weaponry includes:

* Granit (SS-N-21 Sampson) submarine-launched LACMs with a range of approximately 3,000 km; they are usually equipped with nuclear warheads.

* Yakhont supersonic ship-to-ship missiles, with a maximal rate of 3 Mach (1,000 m/s) and a range of about 300 km.

* Advanced torpedoes and missile-torpedoes.

The submarine could dive to depths of 520-600 m and sail autonomously for 100 days. Gepard was built at Severodvinsk Shipyard. Two more Akula II-class submarines remained half-built in Severodvinsk at the beginning of 2002. The Russian Defense Ministry has no money to finish them.

At the same time, one or two Akula I submarines remained unfinished  for the same reason  at Komsomolsk-na-Amure Shipyard. However, Akula I, as a "slightly obsolete" model, is presently of no particular interest to the PLA Navy.

Very probably, in 2003-2005, the PLA Navy will concentrate efforts on purchasing Akula-II submarines from Russia. Some sources give $2 billion as the possible bargaining figure. At the same time, Huludao Shipyard could get the technology to manufacture Akula II.

Some reports in early November in the Hong Kong media confirm this conclusion.

Dr. Alexandr V. Nemets is co-author of "Chinese-Russian Military Relations, Fate of Taiwan and New Geopolitics."

Type 093
The ONI new Type 93 SSN will be similar to Russian second generation designs such as the Victor III. The launch of the initial unit of this class from the Bohai Shipyard is expected around the year 2000. As with the Song SSK, the new submarine will incorporates a hydrodynamically efficient hull form, a single shaft and a highly skewed 7-bladed propeller. The Type 09-3 it is expected to deploy submerged-launch anti-ship cruise missiles, possibly a follow-on to the C801s, as well as the projecte Land Attack Cruise Missile.
