Xia Class Submarine 1 12 x JL-1

ype 092 (Xia Class) Ballistic Missile Nuclear Submarine

The Type 091 (NATO codename: Han class) is China's first generation nuclear powered attack submarine (SSN) built by Huludao Shipyard in Huludao, Liaoning Province. A total of 5 boats (401 to 405) were built between 1967 and 1987. Currently these boats are deployed in the PLA Navy North Sea Fleet based at Qingdao. China is reported to be building the next generation nuclear attack submarine (Type 093) to replace the obsolete Type 091.


PROGRAMME

The Type 092 (NATO code-name: Xia class) is China's first and only ballistic missile nuclear submarine (SSBN). The boat greatly increases the survivability of China's strategic nuclear forces during a preemptive nuclear strike by the enemy, and provides Chinese leaders with a reliable means for nuclear retaliation. Apparently such a capability would also greatly strengthen China's deterrent posture.

The first ship Changzheng 6 (406) was launched in 1981, and became operational in 1983, though the JL-1 submarine launched ballistic missile (SLBM) did not conduct a successful fire test launch until 1988 due to problems with its fire-control system. A second ships was reportedly constructed and later was lost in an accident 1985.

The first test launch of the JL-1 SLBM took place on 30th April 1984 from a submerged pontoon near Huludao. Second missile launched on 12 October 1982 from a Golf class diesel trial submarine (pennant 200). The first launch from Type 092 in 1985 was unsuccessful, delaying the final acceptance into service of this submarine. It was not until 27th September 1988 that a satisfactory launch took place.

Currently the only boat 406 is deployed in the PLAN North Sea Fleet based at Qingdao. It started a major modernisation upgraded in late 1995 at Huludao Shipyard and the programme completed in 2001. The upgrades reportedly include replacing the original JL-1 SLBM with the improved JL-1A, which has an extended range of 3,000~4,000 km.

With only one single Type 092 SSBN, it is not possible for the PLA to establish an effective underwater nuclear strike capability, which can guarantee that at least one boat is ready to launch at any time. However, the boat served as a stepping stone in the development of a more comprehensive Chinese nuclear-powered, submarine launched ballistic missile (SSBN) force in the future.

Operations of the Type 092 SSBN have been limited and the boat has never sailed beyond Chinese regional waters. Despite a potential for operations in the Pacific Ocean, capabilities would be very limited against modern Western or Russian ASW capabilities.

DESIGN FEATURES

The Type 092 SSBN was derived from the Type 091 (Han class) SSN, with a lengthened hull to accommodate 12 JL-1 SLBM launch tubes.

COMMAND SYSTEM

The Type 092 may be fitted with a multi-purpose combat data and command system which provides information for submarine control and torpedo firing. The boat also has a fire-control system for SLBM aiming and firing.

MISSILES

The Type 092 carries 12 Ju Lang-1 (Ju Lang = Giant Wave, NATO code-name: CSS-N-3) or modified JL-1A SLBMs. The missile uses inertial guidance to a maximum range of 2,150km, and carries one single 250kT nuclear warhead.

TORPEDOES

The Type 092 has six 533mm bow torpedo tubes, and carries a total of 12 Yu-3 (SET-65E) torpedoes (active/passive homing to 15 km at 40 kt; warhead 205 kg).

RADAR

The Type 092 has an I-band surface search radar (NATO code-name: Snoop Tray).

SONARS

The Type 092 is fitted with Trout Cheek bow-mounted, medium-frequency sonar for active/passive search and attack; and a DUUX-5 low frequency sonar for passive ranging and intercept.

COUNTERMEASURES

Countermeasures include a Type 921-A radar warning receiver and direction-finder.

PROPULSION

The Type 092 is powered by a nuclear, turbo-electric arrangement, consisting of one pressurised water reactor (PWR) rated at 90MW, with 2 shafts.

中国有几艘406？（组图）

　　中国究竟有多少406？我不知道，但可以从近几年拍摄的照片里可探一二，406不停地在大改，但短短几年就能改出好几种的406,时间肯定不够，更不可能改出这么多的面孔。
　　
　　让我们下面仔细欣赏不同的照片里有多少种面孔，下面这图据说是最新被美国“曙光女神”偷拍到的最新改型406，其实面貌有一新。

　　核潜艇,在1992年以前，我国的全部核潜艇均部署在北海舰队。此后，海军首脑机关从均衡部署考虑，陆续调走了几艘核潜艇给东海和南海舰队。但北海舰队仍拥有我国最强大的的核潜艇编队，据估计目前仍有6艘在役，有一艘093第二代新型核攻击性潜艇在北海舰队进行各种试验，尚未进入现役，将来该新艇是否会配置给北海舰队，还不好说。长期以来北约通过各种侦察渠道，发现的中国弹道导弹潜艇只有舷号为406的一艘。北约看到的弹道导弹潜艇舷号只有406是对的，但就此认定只有一艘却是错的。406舷号的潜艇共有三艘，分别是406甲、406乙和406丙，军方这样做是否为了迷惑抑或有其他目的，实在不得而知。
