Submarines of the People's Liberation Army Navy
From Wikipedia, the free encyclopedia
Submarines have long been one of the three focuses of the People's Liberation Army Navy (the other two are aircraft and attack boats), and when the decision was made in the late 2006 to concentrate on building other principle surface combatants to strengthen the air defense and to further delay the construction of aircraft carriers due to insufficient air cover, submarines will continue to play the lead dominant role in the assult force for the PLAN.

[edit] Nuclear attack submarine force
Nuclear submarines have been envisaged in the Chinese Navy since the 1950s. Despite ambition and a long history of development, the acquisition of nuclear submarines has been a difficult process. The Cultural Revolution had greatly disrupted nuclear submarine development. The Sino-Soviet split prevented any Soviet assistance in nuclear propulsion, and these propulsion problems have been troublesome to this day.
The first Chinese nuclear powered submarine was laid down in 1967 but not completed until 1974. The Han class has experienced more than 20 years of development, the last of the class not being commissioned until 1990. Only five hulls have entered service and have been reported to have experienced nuclear reactor difficulties (though this has been greatly overcome in some aspects by French and subsequent Russian assistance). The Han class since their commissionings, have gone through major upgrades and numerous refits. It is believed that long refits have often meant that these submarines spend more time in port than out at sea, greatly affecting their operational capacity. Combat capabilities of the Han seem to be undermined by the poor and noisy nuclear reactors. Their initial design and weapons fit seem inadequate if confronting other submarines and ships in Western navies. Hull 401 (and possibly 402 as well in the near future) has been retired from active service by 2005. All remaining hulls however have been greatly refitted with new sonars and anechoic tiles (that reduce noise levels). The Han has mostly operated in local waters, but since the 1990s, Hans have been used more aggressively. A Han shadowed a US carrier battle group in the mid 1990s, and more recently, a Han was operating around Japanese waters, prompting a Japanese task group to pursue the submarine out of its territory. The Han is far from being as capable or effective as the American Los Angeles class SSN. But with their recent improvements, they can pose a great threat by operating deep in the Western Pacific and attacking targets that are not so well protected by ASW coverage.
A new class of SSN has been in development since the 1980s, as the PLAN sought a replacement for the Han class. Little information has emerged about the Type 093 SSN project, but it is believed to have great Russian influence. The 093 design maybe similar and comparable to the Russian Victor III class, signifying a significant step forward for Chinese nuclear attack submarines. The 093 has been the focus of much attention from US and Asian military analysts. Its improved capabilities will undoubtedly increase PLAN power in the region and its ability to carry war to the West Pacific. Such submarines can escort future SSBNs as well as attacking US Navy carrier battle groups in the deep ocean. There have been reports that the first hull was launched around 2001, with a second hull also launched a few years afterwards. There has been a lack of photographic evidence, though these submarines being a top secret priority of the PLAN, have been reported operating from submarine cave-bases in Northern China.
There have been numerous reports that China has the option of buying or leasing Russian nuclear attack submarines, particularly the Akula class. It is unlikely however that Russia in the forseable future is willing to sell such high level platforms to China, nor is China interested in wasting money on purchasing run down Russian attack submarines considering the near completion of 093 developments.
[edit] Ballistic missile submarine force
China had engaged in the development of submarine launched ballistic missiles since the 1950s, with the acquisition of a single Soviet Golf class conventional powered ballistic missile submarine. The Golf class has three launch tubes. Using this single hull, the PLAN acquired experience and tests from this platform. The Golf played a major role in China's JL-1 SLBM development project. The first successful launch of the JL-1 SLBM took place in 1982 from a submerged pontoon, and the first successful launch from a submerged submarine was in 1984 from the Golf test submarine. It is believed the single hull is still serving as a test platform for different missile technologies, as well as a test launcher of the JL-2 missile.
China's first SSBN, the Xia 092 class hull 406, was laid down in 1978, launched in 1981 and commissioned by 1983. The JL-1 missile was not ready until the first successful test launch of the missile from the Xia in 1988. Previous launch attempts from 1985 had failed. Its primary weapon is the JL-1 SLBM, with 12 launch tubes, as well as six 533 mm tubes for self defense. Because of only one hull, the PLAN does not possess the capability of the other superpowers to maintain a constant SSBN patrol. The missile's short range also permits the 092 to launch its missiles against regional targets only. Striking targets far away require the submarine to travel dangerously closer to enemy waters.
The PLAN currently has plans to acquire a new class of SSBN, with a projected number between three to six projected. The 094 is believed to have been heavily influenced by Russian assistance. It features 16 launch tubes for the longer ranged JL-2 missile, which has an 8000 km range that can carry 3 to 4 MIRVs. The 094 would be permitted to patrol nearer Chinese waters, with the ability to launch its missiles against continental US targets. Some reports have indicated that one hull has been launched, though there is a lack of photographic evidence.
[edit] Conventional submarine force
Submarine warfare is regarded as a vital part of PLAN's coastal defense doctrine. Large numbers of conventional powered submarines have therefore been in service, and this force makes up the bulk of the PLAN's submarines, making it the third largest submarine force in the world today. The PLAN currently operates five different classes of conventional submarines. In times of war, these submarines can be used for disrupting lines of shipping, laying mines, attacking ships, defending against enemy submarines and later generations of Chinese SSK can employ use of anti-ship missiles. Being quiet underwater combatants, they represent a considerable threat to regional navies.
[edit] History
The first class of submarine to be operated by the PLAN was the Soviet Whiskey class. These were little different from the German U-Boat designs later in the war years. The Whiskey was imported from the Soviet Union and subsequently built in considerable numbers (40+). Most of these hulls have been removed from service by the mid 1990s.
The second type to be operated also owed its origins to the Soviet Union. The Romeo class was principally based upon late war German U-boats. The Romeo was also copied in China as the Type 033 submarine. Production of this submarine took place since the 1960s until the 1980s (even till the early 1990s). It has been estimated that more than 100 have been produced for the PLAN and for export. The 033 formed the backbone of the PLAN submarine forces, mostly patrolling near the coast. Their main armaments were primitively guided or unguided torpedoes and mines. The 033 generally had very limited ability to engage more advanced submarines in modern warfare as well as being quite vulnerable to modern ASW sensors and weapons. By the late 1990s, a large number of 033s had been retired from active duty and pulled into reserves. A handful of upgraded hulls remain in service. These upgraded hulls have new sonar fits and other improvements that keep them effective as patrol submarines.
The Ming class 035 is based on the 033. It could be considered as China's first indigenously designed submarine despite its similarities to the Romeo class. The Ming did not particularly perform well in initial hulls, being first commissioned in 1974. One of the first boats were scrapped after a fire. Initial hulls have since been scrapped, but major improvements and eventual reliability have permitted production to have proceeded at a rate of one to two boats a year between 1988-1995, then resuming again from the late 1990s to 2001. At least 17 hulls are still in service, with later hulls using modern sonar including the French DUUX-5. The later hulls of the Ming class may have been employed for testing Air Independent Propulsion (AIP), which would significantly reduce the noise level of the submarine. Mings have been reported to have been exercising more frequently, particularly the recent incursions into Japanese waters. On one occasion the Ming surfaced for a brief period within Japanese waters before submerging again. In 2003, Ming 361 was lost with all hands. It was speculated that 361 was testing an AIP system which could have caused the death of the entire crew almost instantaneously (as the crew were found dead at their quarters with the submarine intact).
The PLAN in the 1990s had sought to acquire a modern conventional submarine with emphasis on sensors, weaponry, and modern capabilities to engage enemy submarines in modern warfare. In 1994 it ordered two Kilo 877EKM type submarines from Russia, which were delivered by 1995. In 1996, two improved Kilo 636 submarines were ordered, delivered between 1997-1998. In 2002, a $2 billion deal was signed for eight more Kilo 636, these submarines particularly fitted with the capability of launching the Russian Novator 3M-54E Klub S cruise missile capable of engaging land and sea targets at 220 km. The Kilo class represents a huge leap forward in the PLAN submarine fleet. Originally a Soviet design in the 1980s, the Kilo was meant to be one of the world's quietest class of submarines, said to be as quiet as the US Los Angeles class. With 12 Kilos operational by 2006, it is unclear whether PLAN will buy anymore of these potent vessels. But these Russian boats have undoubtedly increased the capability of the PLAN submarine force.
Despite the purchase of the Kilos, the PLAN has continued to develop indigenous designs. The Song class design was first launched in 1994 with sea trials in 1995. It featured Western influences with a German propulsion system, seven blade skewed propeller and noise-reduction rubber tiles; however, the first hull retained the traditional stepped sail. The first hull was not fully operational until 1999. As a result of the sea trials a significantly modified design emerged as the Song 039A, with a number of improvements, including a conventional sail. Song 039A appears quite similar to the Agosta class in appearance. By 2006 about 12 hulls have been confirmed to be built so far, indicating the class has performed satisfactorily. The Song presents a major milestone to indigenous submarine designs, being comparable in capabilities to contemporary Western submarines. Song submarines are armed with torpedoes and a sub-launched variant of the YJ8 anti-ship missile. An AIP system may be installed in the future.
Internet photos emerged in 2005 of a new class of submarine dubbed the Yuan class. The hull seems to resemble Russian influences (as it is similar to the Kilo) while also adapting features found on the 039A. The Yuan is expected to adapt an AIP system to achieve maximum quiet operational capabilities. The Yuan could be armed with advanced Russian and Chinese torpedoes and cruise missiles. The Yuan came as a surprise to US military intelligence, as the submarine's existence was entirely unknown until internet images emerged. This unprecedented class of SSK is expected to have capabilities which surpass the Kilo and Song designs. Series production could begin as soon as sea trials are deemed successful.
[edit] Outlook
The future fleet of conventional Chinese submarines is a deadly quiet force that could perform defensive and offensive operations. The future fleet will compose of the Kilo, Song and Yuan types, as the Romeos and Mings are phased out of service. China is reported to have the option of purchasing the more advanced Russian Amur class SSK. With the success of indigenous programmes however, future purchases of foreign submarines look bleak.
