Chinese Type 093A or 093G SSN armed with YJ-18 Carrier Killer Missiles

What may be 3 Chinese Type 093A/093G SSN or SSGN submarines. An obviously blurry photo of a clarity far below military satellite standards. Nothing as clear as "reading a car's number plate".

Ecns of China reported April 3, 2015 a new version of China's Type 093 (NATO "Shang class") SSN. The new version is variously named Type 093A or 093G. The ability of 093A/093G to mount vertically launched YJ-18 anti-ship missiles may cause the 093A/093G to be called an SSGN. There  seem to be no reliable photos of the YJ-18.

If the longer length and other differences of the Type 093A/093Gs are accurate it is possible China may eventually rename them Type 095s. The 095 is expected to feature unobservable features including an advanced reactor, lower acoustic signature and the visible VLS tubes (with VLS noted on the 093As/093Gs).

Just a note of caution that the 093A/093G reports seem to rely on 3rd or 4th hand Taiwanese sources in the information loop. The message that 093A/093Gs with their missiles are "carrier killers" of course worries the US. A message that directs more US military attention weapons-money-opportunities to Taiwan is beneficial to Taiwan. Taiwan definitly needs US help to pressure some country to help Taiwan build or acquire four new submarines.

Application of the term "carrier killer" to the YJ-18 should not imply that the YJ-18 is a new threat. There may be many similarities between the 093A/093G's YJ-18 anti-ship missile and the BrahMosYakhont or Klub-Sizzler. Significantly the Klub-Sizzler has already been fitted by Russia to China's 12 Russian built Kilo class submarines. Now China is taking the evolutionary (no game-changing) step of fitting Klub equivalents (YJ-18s) to faster moving and longer submerged Type 093A/093Gs.

All this missile activity is not a major departure from conventional and nuclear propelled submarines pre-existing torpedos capabilities - with torpedos being able to "kill"/destroy carriers and other major warships.

The YJ-18 may also owe some design attributes to the YJ-12 "a supersonic Chinese anti-ship missile developed in the 1990s".

Comment - while the YJ-18 sounds like an awesome weapon the hierarchical autonomy, tactics and efficiency of their human operators are very important. The human element is often mistakenly disregarded. How smoothly the YJ-18s fit into China's broader network of anti-shipping sensors is also a consideration.

The report from Ecns of China, April 3, 2015 has the string http://www.ecns.cn/military/2015/04-03/160484.shtml and is below  .

[Chinese PLA] "Navy to get 3 new nuclear subs

   
2015-04-03 09:07China DailyEditor: Si Huan
Three cutting-edge nuclear-powered attack submarines have been manufactured and will soon be commissioned by the Chinese navy, according to media reports.

China Central Television showed a satellite picture earlier this week of three submarines anchored at an unidentified port [see first picture above - very blurry], saying the vessels are China's most advanced Type-093G nuclear-powered attack submarines, just completed by a Chinese shipyard and a waiting delivery.

With a teardrop hull, the submarine is longer than its predecessor, the Type-093, and has a vertical launching system, the report said.

Another article carried by the People's Liberation Army navy's website said the Type-093G's wing-shaped cross-section [?] is designed to improve speed and mobility as well as reduce noise, and that the vertical launcher is capable of delivering the country's latest YJ-18 supersonic anti-ship missile.

China established its nuclear-powered submarine force in the early 1970s but had never shown it to the outside world until 2009, when two nuclear submarines took part in a parade marking the 60th anniversary of the PLA navy's founding.

The Type-093G is reported to be an upgraded version of Type-093, China's second-generation nuclear-powered attack submarine, which entered active service several years ago.

Cui Yiliang, editor-in-chief of Modern Ships magazine, said: "Though China was comparatively late in developing advanced nuclear-powered submarines such as the Type-093G, we used a lot of the most cutting-edge technologies and equipment on our submarines, enabling them to compete with their foreign counterparts."

He noted that China has researched the vertical launching system for many years and has installed it on other submarines and surface ships.

"Judging from the vessel's design, the Type-093G should have strong anti-ship and counter-submarine capabilities," said Yin Zhuo, a senior expert with the navy. "It is also likely to be upgraded with the capability of striking land targets with cruise missiles in the near future."

He added that the navy has formed a reliable logistics system for its nuclear submarine fleet.
Liu Jiangping, a naval equipment expert in Beijing who had served in the PLA navy for decades, said the vessel's vertical launching system enables the submarine to launch long-distance strikes from underwater, increasing the vessel's survivability in war.

The strategic force of the PLA navy now has about four nuclear-powered Type-094 ballistic missile submarines, up to six Type-093 nuclear-powered attack submarines and about three old Type-091 nuclear-powered attack submarines, CCTV quoted foreign media reports as saying.[note the report of six 093's may be Taiwanese deception. Wikipedia (see its sidebar) based on US DoD reports reported only 2 active 093s in June 2014. Wikipedia's sidebar agrees there are 3 active 091s however ].

Another report, from Deagel.com, last updated February 4, 2015, goes into much more detail on the YJ-18 anti-ship missile. The similarity to BrahMosYakhont or Klub-Sizzler in function is obvious. The report's string is http://www.deagel.com/Anti-Ship-Missiles/YJ-18_a002884001.aspx :

"YJ-18 [Missile]


Description:

The YingJi-18 (YJ-18 or Eagle/Hawk-18) is a vertically-launched, long-range, supersonic, sea-skimming anti-ship missile designed by China to kill US Navy's Aegis-equipped destroyers or its equivalents provided to Japan, South Korea or European Navies. The YJ-18 is planned for deployment by the newest People's Liberation Army Navy (PLAN) Type 052D class destroyers and subsequently may be incorporated into existing destroyers and submarines as part of a modernization effort. Its guidance system consists of an advanced inertial navigation, maybe backed by the Beidou Chinese GPS, plus an active radar seeker in the terminal phase. Besides, a built-in data link allows the carrier ship to update the target's location. The Aegis-killer missile existence was first reported in 2013 with an entry into service expected by 2014 or later.

The YJ-18 missile is equipped with a 300 kg high explosive (HE) warhead capable of taking out a destroyer-sized ship. The HE warhead can be replaced by an anti-radiation/electromagnetic pulse warhead that is said can take down up to 60 percent of the enemy ship's electronic systems at a range of 50 meters after detonating. After the vertical launch the missile's turbojet engine is capable of flying at a cruise speed of Mach 0.8 for about 180 kilometers after that point the warhead section separates and a solid rocket engine ignites allowing at a top speed of Mach 2.5-3 for about 40 kilometers. The missile can maneuver at 10G acceleration to avoid enemy interception by air-to-air or surface-air missiles. The missile design and performance is very similar to Russia's 3M54E [Klub-Sizzlerwhich may have been the template for the YJ-18."

Israeli Publicity on Nuclear Capability of its Dolphin 2 Submarines - Yakhont, BrahMos


The upper image is a Dolphin 2 - for size comparison and to indicate the fuel cell AIP additions. Lower submarine image highlights the high number of torpedo/missile tubes - apparently ten on the Dolphin 1s and 2s - useful for rapid nuclear missile launch. (Diagram courtesy Next Navy)

Most probably very similar to the Russian-made P-800 Oniks, Yakhont , NATO reporting name SS-N-26 "Strobile" is the Russian-Indian BrahMos (above) . The mach 2.8 end run makes Yakhont and BrahMos difficult to detect and shoot down in time. With a probable land attack capability and air-launched range longer than the notional 290km they will be a proliferating weapon to watch. (Diagram courtesy - Russian for "Military Parity" website).

Here's the BrahMos missile showing its capabilities in land, ship and submarine launch. Its ability to hit what look like 2-4 m targets supports claims of +2/-2 m accuracy.

In terms of relevance to Australia the ability of Germany's TKMS-HDW to tailor-make largish Dolphin 2 (2,000+ ton (surfaced)) warm water, submarines for Israel implies a capability to successfully tailor-make future submarines for Australia.

In late March 2015 much of the Israeli media (eg. a haaretz article of March 30, 2015) seem to be carrying Israeli government generated news of technical progress with the ISS Tanin nuclear capable submarine. Tanin appears to be the most complete of Israel's Dolphin 2 class SSKs. It does not appear the Tanin is anywhere near formal commissioning - so why the publicity? 

The media reports substantially carry mention of the nuclear second strike capabilities of the Dolphins. This is a subject that requires Israeli Government permission to be published.

The reason to mention second strike appears to be Syrian government acquisition and possible deployment of Russian-made P-800 Yakhont, NATO reporting codename SS-N-26 "Strobile" - a supersonic cruise missiles. What has Israel worried is not so much the usual anti-shipping role but more the Yakhont's land attack capability. 

With Syria's record of using Sarin gas on crude warheads against civilians Israel's worry about the Oniks would be considerable. Syrian use of radiological warheads might also be feasible and of course high explosive. The chances of Sunni rebels or Sunni governments acquiring Yakhonts adds an extra worry. See my May 21, 2013 article on Israeli airstrikes on Syria.

Media stories on Israeli second strike would of course have a "put pressure on Iran" intent as well.

In an added twist India and Russia are jointly developing the BrahMos version of the Yakhont. India wishes to market BrahMos to several countries in the Asia-Pacific. Meanwhile Russia has already supplied the Yakhont in Australia's region to Indonesia and Vietnam

Please link with Submarine Matters' Israeli Dolphin Sub, Nuclear Armed, Conventionally Propelled, February 25, 2012 which mentions possible Israeli developed nuclear warheads on submarine launched Harpoon missiles (SLCMs). Israel's current nuclear SLCM may be the socalled Popeye Turbo or perhaps an Israeli version of the (jointly developed?) Indian K-15 small ballistic missile. The Dolphin 1s and 2's extraordinarily high number of ten torpedo tubes (including 4 unusually large 650mm tubes) implies the ability to rapidly launch ten nuclear land attack missiles. 

The sequence of the Dolphin 2s being delivered by Germany then modified/completed in Israel (Haifa) is a bit puzzling. Based on "Boats" but updated:

Dolphin 1 class
  • Dolphin – delivered May 1998 – commissioned 1999
  • Leviathan (trans. "Leviathan" or "whale") – delivered 1999 – commissioned 2000
  • Tekumah (trans. "Revival") – delivered 2000 – commissioned 2000
AIP Dolphin 2 class
  • Tanin (trans. "Tannin" or "Crocodile") – delivered 23 Sept 2014 - enter service 2015, commisioning 2015 or 2016?
  • Rahav (trans. "Splendour") – delivered 29 April 2013 - enter service in 2015 or 2016?
  • Name not assigned yet. Ordered 21 March 2012. Enter service in 2017 or 2018?

Tanin was apparently received months after Rahav yet Rahav will be completed later. 

Much of the Israeli modification/completion would be for the electronics and loading fitout for the nuclear missiles. Publicity about Germany in 2012 being overly knowledgable and helpful to Israel regarding the nuclear missile loading fitout must have resulted in Israel taking over that whole job. Perhaps Israel's procedures are not fully developed - hence the Tanin-Rahav completion anomaly.
