8 CHINESE SSK'S FOR PAKISTAN - 50 CHINESE MADE JF- 17 TOO.




POSSIBLY QING CLASS SSK's [TYPE 032]





Pakistan's Defence forces , specially Pakistan's Navy has been quite vocal of arrival of Russian Nuclear powered submarine to Indian shore. Pakistan Navy chief has already told US Defence Magazine that arrival of Russian Nuclear powered submarine and India’s own Indigenous development ,will have adverse effect on its operational capability in Indian ocean . and also mentioned that Pakistani navy is already working on plans to counter this latest threat put forward by Indian Navy .

Indian Defence Experts believe that Pakistan is already working on a counter plans and might just surprise Indian pretty soon in future by producing or acquiring a Nuclear powered submarine . Pakistan always has a quieter way of weapons acquisition and even managed to keep many defence project low key affair .

Rakesh Sharma Indian Defence Expert told that “General Musharraf way back in 2006 had mentioned to a Pak daily that technology for development of a Nuclear Submarine existed in Pakistan”, but its seems help will come from its tried and tested friend china .

China has per media will be supplying 6 conventional attack submarine of Qing class , which will be equipped with a Stirling-cycle AIP system and will be able to carry up to three nuclear warhead-carrying CJ-10K LACMs each. The double-hulled Qing-class SSK, with a submerged displacement close to 3,600 tonnes, bears a close resemblance to the Russian Type 636M SSK, and features hull-retractable foreplanes and hydrodynamically streamlined sail.

Experts suggests that Pakistan’s nuclear submarine is likely to be based on the Qing Class Chinese SSK. highly advanced electric propulsion system of Qing Class Chinese SSK will able Pakistan to replace diesel engine power generation with a nuclear power plant.

Pakistan also has the expertise of submarine construction , with potential help may have been the transfer of technology from France with the Agosta 90B submarine purchase. A number of key technologies were transferred including design and development skills and tools. Building of hulls and experience with Western subsystems, many of which are used in the French nuclear submarines would help the Pakistani SSN / SSBN.


Pakistan with expertise and transfers of technology from China , will be able to field their first nuclear submarine in next 5 to 8 years and brand it “Indigenous “. But experts have difference of opinion on usage of this submarine in both forces , While Nuclear Submarine in Indian navy will complete Nuclear 2nd strike option for India , but Pakistani nuclear submarine might be built to attack prized Indian Aircraft carriers in case of conflict . India who will have 3 or more fleet of aircraft carriers in near future will always be Pakistani navies prime target , even in 1971 Indo-Pak war , Indian aircraft carrier was always a prize target for them .



JF 17 - THUNDER STORY

Pakistan will acquire 110 latest JF-17 Thunder fighter jets from China as the two countries forge closer economic and defence cooperation following President Xi Jinping's visit here earlier this week, a media report said today. Radio Pakistan reported that China will deliver the first batch of 50 jets over a period of three years.The Head of Chinese Aircraft Industry told a Chinese daily that under the contract signed between the two countries, Pakistan will receive a total of 110 JF-17 Thunder fighter aircraft from China. It is not clear when the delivery of the remaining 60 jets will be completed. The JF-17 Thunder is also built in Pakistan as China has already transferred its technology. But Pakistan needs more fighter jets at faster pace due to its fight against Taliban militants. Xi also launched a $46 billion economic corridor to link China's western region to Pakistan's Gwadar port on the Arabian Sea. During Xi's visit, a fleet of eight JF-17 jets escorted the special aircraft of the Chinese president when it entered Pakistan's airspace. The two countries signed 51 agreements to boost economic cooperation during Xi's trip.Earlier, reports said China would provide eight latest submarines to Pakistan, more than doubling its fleet, in a deal worth $4-5 billion.

Pakistan has witnessed new defense acquisitions in this decade than any other, and in the center of it all is the new fighter which was designed by China with partial funding from Pakistan. It is formally known as JF-17 Thunder. When the fighter was in development, Pakistani online communities were jumping with excitement comparing it with its arch rival India’s modern combatants Su-30MKI, Mig-29S & Mirage-2000H. There were claims of it featuring western Radars and long range missiles, & Chinese ordering some due to its superior capabilities. But the reality is far from it.

China having spent significant amount of money into a fighter which it is never going to use, most probably forced Pakistan to accept its avionics to offset some its development costs. Chinese who are known for their self reliance first and quality next, are further downgrading JF-17s capabilities with their poorly copy-pirated avionics. Along with their dubious weapons, any chance of JF-17 maintaining BVR edge over its adversary’s front-line combatants, for the most part, is unlikely.

Even in close combat JF-17 lacks what it takes to win the fight. Its spine, & wings bearing resemblance(in wing twist & wing area) to a fighter which china knows inside out, the J-7, doesn’t have wing twist nor does it have enough area to provide a low wing loading. Its performance during low speeds and high alphas would be very dangerous for the pilot indeed. It has a Maximum G loading of only 8, as claimed by PAC. Its thrust to weight ratio is another negative point. When its arch rival, the Indian Air Force(IAF), was overtly critical of Tejas for having a low Thrust to Weight ratio, maybe they should have compared it with JF-17 which has even less, even with Emergency Thrust. Pakistan Aeronautical Complex(PAC) proudly displays the RD-93’s “Combat thrust with afterburner” as 19,200lbf, while the whole defense community knows RD-93’s thrust is 18,300lbf and the only real thrust increase was achieved with its new re-designed Sea Wasp RD-33MK engines- which has been explicitly stated by Klimov. However, Klimov’s RD-33 series 3(or series 2?), whose avatar is RD-93 with re-positioned Gear boxes, has a provision for emergency thrust which Klimov says can produce 8700kgf(~19200lbf) in their officially released document. They further state that as “Take-off emergency mode”. So the mentioned thrust can only be used during take-off where the Air is denser, and also only during emergency situations since it would seriously lower the engine’s lifespan. This is a far cry from PAC's “Combat thrust” claim. Why this is being stated is because, the engines(bought by the Chinese after pressurizing the Russians) are the only non-Chinese & non-Pakistani component, and even there they have lied about its capabilities. Hence the true, lower than published, specifications of Chinese and Pakistani components are open to any one’s guesses. In any case, the close combat capabilities of JF-17 is below average or average at best.

The next Achilles heal is JF-17’s speed. For a good interception, speed is an important criteria. However JF-17’s max speed is Mach 1.6 which is claimed by PAC. This indicates that JF-17 is draggier. When compared, their F-7s(Reverse engineered Mig-21s) have higher speed of mach 2+ with a lower thrust engine. The IAF fighters which it is going to face, all have speeds greater than the Thunder.

So why is Pakistan still inducting more and more of this fighter, which its critics increasingly call it Junk Fighter – 17 ? The answer may lie with Pakistan’s recent trauma & its psyche. Having sanctioned by the U.S, the star of their airforce, the F-16s were severally hit by lack of spares and most of the time grounded. The other 2 sources to procure modern Aircraft- Russia, have been sealed off due to the legacy of Soviet era friendship, current market in India & India’s pressure- and the other source, the European Union, for their extremely high costs. The third source, the Chinese, at that time were still flying their reverse engineered Mig-21s. In those circumstances, “Never again” was the motto of PAF and it instantly jumped into the project of further reversing the reverse engineered Mig-21, known as Super-7(a.k.a Super F-7) to obtain self reliance. The result of that project is the JF-17. So the decision was appropriate at that time, in those situations. However now with China having developed the J-10, and going by the recent reports of offering ToT(Transfer of Technology) to Pakistan, one wonders why are the Pakistanis still ordering 250 planes. Is the trauma of F-16 sanctions so high that they don’t even trust the Chinese? This can't be the case because they still need the Chinese to procure the RD-93 engines for them, even after the Chinese transfer all their associated JF-17 tech to PAC. So why...? The answer lies with their ego/psyche rather than the trauma. Unlike J-10, Pakistan shares copyright to JF-17 and that, for some weird reason, gives them something to celebrate about. This is strange for the reason, war machines are for fighting wars and achieving tactical & strategic objectives, not for gloating about who holds the copyrights. When JF-17 comes face to face with MKI or SMT, there won’t be much to celebrate about it, or the few millions if at all it earns though exports. In the end, it’s all about defending ones homeland from the enemy, and not copyrights.

CHINA - WHATS THEIR MOTIVE?



 CHINESE SUBS IN THE INDIAN OCEAN

China’s submarine fleet made its first known trip into the Indian Ocean, according to a report by the Wall Street Journal. A Chinese attack submarine passed through the Straits of Malacca between Malaysia and Indonesia with sightings near Sri Lanka and the Persian Gulf.

It’s the latest report of the significant steps forward the Chinese navy has taken in advancing its submarine fleet. Earlier this year, a U.S. Navy report estimated that the Chinese navy has nuclear-armed ballistic missile submarines able to launch strikes against the United States from the middle of the Pacific Ocean.
The Chinese navy has ambitious plans over the next 15 years to rapidly advance its fleet of surface ships and submarines as well as maritime weapons and sensors, according to a report by the Office of Naval Intelligence.

Earlier this year, ONI issued an assessment on the Chinese navy as part of testimony to the U.S. China Economic and Security Review. ONI leaders found that China’s navy has evolved from a littoral force to one that is capable of meeting a wide range of missions to include being “increasingly capable of striking targets hundreds of miles from the Chinese mainland.”

The Chinese navy has 77 surface combatants, more than 60 submarines, 55 amphibious ships and about 85 missile-equipped small ships, according to the report first published by the U.S. Naval Institute.
ONI raised concerns about China’s fast-growing submarine force, to include the Jin-class ballistic nuclear submarines, which were expected to commence deterrent patrols in 2014. The expected operational deployment of the Jin “would mark China’s first credible at-sea-second-strike nuclear capability,” the report states.

The submarine could fire the JL-2 submarine launched ballistic missile, which has a range of 4,000 nautical miles and would “enable the Jin to strike Hawaii, Alaska and possibly western portions of CONUS [continental United States] from East Asian waters,” ONI assessed.

In addition, a 2014 Pentagon Annual Report to Congress on military and security developments said the Chinese have three operational Jin-class SSBNs (ballistic missile submarines) and up to five may enter service before the Chinese proceeds toward a next-generation SSBN.

The ONI report says the Chinese currently have five nuclear attack submarines, four nuclear ballistic missile submarines and 53 diesel attack submarines. Overall, China’s fleet of submarines has quickly increased in offensive weapons technology over the last 10 years. A decade ago, only a few Chinese submarines could fire modern anti-ship cruise missiles (ASCMs). Now, more than half of the conventional attack submarines are configured to fire ASCMs, the ONI report states.

“The type-095 guided missile attack submarine, which China will likely construct over the next decade, may be equipped with a land-attack capability,” the assessment explains. This could enable Chinese submarines with an enhanced ability to strike U.S. bases throughout the region, the report adds.The Pentagon’s China report affirms that the expected deployment of nuclear-armed JL-2s will, for the first time, give China an at-sea nuclear deterrent capability.

One analyst said the Chinese appear to be trying to position themselves as a nuclear global super power able to both assert regional dominance and project power around the world.”China clearly appears to be pursuing a great power nuclear-deterrence strategy. They are making progress but it is not fast paced. It is kind of appropriate for a military that has two missions, guaranteed deterrence and an interest in showing its ability as a superpower,” said Daniel Goure, vice president of the Lexington Institute, a Va.-based think tank.
In recent decades, the Chinese military has had more of a regional focus instead of ICMBs, something which may now be changing in light of growing ambitions, continued rapid technological expansion and military modernization, Goure explained.

“We know from watching the Soviets how hard it is for these countries to build western-equivalent militaries and nuclear enterprises. The Russians almost broke trying to build a Navy that would out do us,” he added.
However, Goure added that the Chinese navy has a long way to go before it could emerge as a credible competitor to the U.S. Navy.

“Are they really going to go the route of building their own kind of competitor to the U.S. Navy? That is expensive and difficult – at a time when their economy is slowing down,” Goure said.
The Navy’s Atlantic Fleet submarine commander recently voiced concern about China’s submarine modernization efforts.

“The world has become multi-polar and we have competition for global influence and power from a rising China – which is very much on our mind. The Chinese have had ballistic missile submarines in some form for a while. Their pace has accelerated and they have several nuclear ballistic missile submarines and are continuing to build more,” said Vice Adm. Michael Connor.
