India is Banking on Russia's S-400 Missile to Thwart China Threat
India's defence sector is likely to get a major boost with New Delhi close to finalizing a deal for the world's most advanced anti-ballistic missile system – the S-400 - during Defence Minister Manohar Parrikar's visit to Russia
Mr Parrikar, who is scheduled to leave for Moscow on Saturday, in an interview to ITAR-TASS expressed hope to finalise the deal by the time Prime Minister Narendra Modi visits Moscow in December.
The S-400 is designed to protect key installations such as nuclear reactors, government installations and big cities and can intercept enemy missile more than 400 kilometres away.
The S-400 Triumf is capable of countering all air attack weapons, including tactical and strategic aircraft, ballistic missiles and hypersonic targets such as the US F-35 fighter jet.
The S-400 can engage up to 36 targets simultaneously with as many as 72 missiles at altitudes of five meters to 30 km.
The cost of the acquisition and the number of S-400 systems India will acquire is not known at this stage.
Parrikar's visit comes as the government's Defence Acquisition Council cleared defence projects worth more than Rs. 15,000 crores.

It was rumored that a new heavy fighter bomber (J-18) based on J-16 is being developed at 601/SAC since early 2010s. It features a widened twin-seat cockpit similar to Russian Su-34 and adjustable leading edge vortex controllers similar to Russian T-50. First flight was rumored to have taken place on October 27, 2015 but this has not been confirmed."
Pakistan has Built low-yield Nuclear Weapons to Counter Indian Aggression
Pakistan has made low-yield nuclear weapons in response to India’s actions under its cold-start doctrine, Foreign Secretary Aizaz Chaudhary told a news briefing here on Tuesday.
This is the first concrete explanation from a senior Pakistani official on how Islamabad plans to deal with India’s so called cold-start doctrine, now re-named the pro-active strategy.
It is also a rare explanation of Pakistan’s decision to make tactical nuclear weapons to deal with the possible threat of Indian aggression.
Briefing the Pakistani media on Prime Minister Nawaz Sharif’s visit to Washington, Chaudhary also said that Pakistan would not sign any nuclear deal with the United States during the visit.
Earlier, Prime Minister Nawaz Sharif reaffirmed that Pakistan’s national interests will be prioritised during his upcoming visit to the United States (US).
The premier was speaking to media personnel in London, en route the US.
“We will protect the national interests of Pakistan during my meetings with US leadership,” said the prime minister.
While responding to a question on recent reports in US media regarding Pakistan’s nuclear arsenal, and plans to limit it, the premier said: “We should not forget who the prime minister was in 1999 when we became a nuclear power.”
Prime Minister Nawaz Sharif also stated that concrete evidence regarding India’s sponsoring of terrorism has been forwarded to relevant people and organisations, and expressed hope that Pakistan’s concerns would be addressed.
The premier will arrive in the US on Tuesday and will likely be asked to bring the Taliban to the negotiating table, days after Washington said it was delaying its withdrawal from Afghanistan.
US President Barack Obama last week reversed a pledge to pull troops out as he admitted Afghan forces were not ready to stand alone against the resurgent Taliban, who briefly captured a key northern city this month.
The US sees Pakistan as one of the few sources of influence over the extremists, and analysts say Washington will use the four-day trip to urge Sharif to keep pushing for a new round of talks.
Yesterday, the Foreign Office had clarified that no “deal” is being discussed between Pakistan and the United States.

Comac C919 takes shape in Shanghai
Final assembly work on the Comac C919 has kicked into high gear, with assembly of the first prototype airframe almost complete.
Pictures released to Flightglobal show an almost complete airframe joined from nose through to the tail. Wing-to-body join has also been done, with the vertical and horizontal stabilisers already attached to the aircraft's tail.
The aircraft is still resting on struts, although the main landing gear and forward landing gear appear to have been installed. The aircraft's wingtip devices have also yet to be installed. No other aircraft are pictured in the final assembly centre area.
A Comac spokesman tells Flightglobal that no systems have been installed on the aircraft.
Over the last six months the Chinese aircraft manufacturer has been taking delivery of the jet's major structures, with final assembly work officially started last September.
Comac has publicly stated end-2015 as the aircraft's first flight target, and the spokesman says the goal remains to strive towards that timeline.
He adds however that major works such as the installation of the avionics, flight control and hydraulics systems still remain to be done. The various systems also have to be integrated and tested.
Tests are however ongoing at full-swing on the C919 iron bird test rig, with more than 50 test engineers and technicians involved.

J-20 and More Thoughts On 5th generation Projects
Most recently, a 7th prototype of J-20 project (No. 2016) appeared and made its maiden flight on September 18th. It’s been 9 months since the last prototype had come out, so this new prototype is a sign that the program has not hit any major stumbling block and was just going through the next iteration in its development. As a refresher, 2 prototypes (No. 2001 and No. 2002) came out and flew in 2011. They were probably the demonstrators of this program. Over 2 and half years later, the 3rd J-20 prototype (No. 2011) came out and was followed by 3 more prototypes (No. 2012, 2013 and 2015). They had some major redesign and changes compared to the demonstrators. So they should be considered the first pre-production prototypes and were probably produced in the same batch. CAC and CFTE have been testing them since that time. I expect that more J-20 prototypes will be coming out in the next few months, since they seem to be building them in batches on this and past CAC project. Compared to the last batch of J-20s, the most noticeable changes have been on the DSI bump and the engine nacelle. The DSI bump looks to be a little larger and people have speculated that some EW equipment may be installed inside. From the relatively few changes between the batches, one can surmise that the J-20 design is more or less frozen.
Indeed, there have already been speculations that the first production J-20s will come out next year to be tested and evaluated by FTTC. While I think that is certainly possible, I think it is also best to tamper one’s expectations and expect some problems along the way. Every 5th generation projects so far have experienced some bumps along the way. The PAK-FA project had fire on one of its prototypes and still has not flown a new prototype since. IAF have continually complained recent years about the technology and progress of PAK-FA. The F-22 and F-35 projects are far more open, so there were many reports of issues along the way. One would expect J-20 to encounter similar issues along the way even if those reports only come out in the rumour mills of Chinese military forums.
With everything that we can see, I think that CAC has been doing a great job with the J-20 project. At this point, I already consider J-20 project to be ahead of PAK-FA in both the design and timelines. In terms of design and technology, J-20 looks to be better configured for stealth from most profiles vs PAK-FA. The next generation AESA radar and the rest of electronic suite are already been deployed J-10B/C and J-16 compared to lack of such Russians platforms. Even the next generation missiles (like PL-10 and PL-15) seem to be further along in development and deployment than similar Russian systems. PAK-FA only seems to be using a more advanced engine at this phase of testing. Considering that the Russians started to research on 5th gen fighter jet in the 80s and first flew PAK-FA a year earlier than J-20, this does not speak very well of Russia’s aerospace industry.
For the past year or two, I’ve read numerous articles coming out of India that complained about the technology, cost and lack of their work share in the PAK-FA project. Since then, there was a fire on one of the PAK-FA prototypes when they were giving a flight demonstration to Indian delegation and have not shown a new prototype since. There have also been numerous online posts about the build problems and quality issues with those prototypes. Now most recently, I’ve also seen a report where India is thinking of pulling out participation in the development of PAK-FA and just buying them straight out of Russia. They probably realized Russia was unwilling to share its most sensitive secrets so they needed to devote more of their R&D resources on their domestic project MCA. At the same time, it also appears that some in IAF is favouring for purchase of more Rafael and less PAK-FA. There are numerous components of PAK-FA project like stealth and propulsion, which are not up to par with the standard established by F-22. If the leap in technology over Rafael is not big, then it makes all the sense to buy the more of the mature platform. Of course, that could also create a disastrous scenario for IAF if J-20 and FC-31 turn out to be much better than Rafael.

China's Super Weapons: Beware the J-20 and J-31 Stealth Fighters
People’s Liberation Army Air Force (PLAAF) of the People’s Republic of China (PRC) has lagged behind the aerial programs of other world powers such as the United States. Now, the PRC has set its sights on producing indigenously designed “fifth generation” fighter jets comparable to the US F-22 Raptor and F-35 Lightning II. Many U.S. officials and pilots suspect that the Chinese have been usinghacked U.S. technology to aid their indigenous development programs. The PRC is also leveraging additive manufacturing technology (better known as 3D-printing) in order to increase speed and efficiency in manufacturing aircrafts and compete with the U.S. The J-20 Black Eagle could be fully operational by 2018, and a second model, the J-31 Gyrfalcon, by 2020. If true, China’s new generation of fighters could have a substantial impact on its ability to either defend what it considers to be sovereign airspace, or to mount an aerial offensive in a wartime scenario, particularly against Taiwan (ROC).
Recent Advances in the PLAAF
Between 1990 and 1992 the PRC purchased 24 Su-27 Flankers from Russia and slightly modified the design to become the J-11 Flanker B+. In response, the U.S. sold 150 F-16 Fighting Falcons to Taiwan. The acquisition of fourth generation Su-27s allowed China’s Air Force to enter modernity, and they have become progressively more capable ever since. In 2010, half of the PLAAF fleet still consisted of jets modeled after 1950s and 1960s Soviet MiG-19 Farmers and MiG-21 Fishbeds, but China’s ability to project air power has increased significantly within the past 5 years. Recently, the PRC and Russia have nearly completed a deal to transfer 24 Russian Su-35 Super Flankers, a potent “generation 4++” fighter, to the Chinese, in addition to China’s scheduled integration of fifth generation technology.
Currently the PLAAF relies on the J-11 as its primary fighter. However, this model is largely unproven. This aircraft is perhaps most recognized as the fighter variant involved in an August 2014 incident in which a single J-11 intercepted a USN P-8A Poseidon surveillance aircraft 135 miles east of Hainan Island. Twice the J-11 came within 50 yards of the U.S. aircraft. The aggressive maneuvering by the Chinese pilot was an example of the PLAAF making it clear that U.S. surveillance is not appreciated within the airspace over its exclusive economic zone (EEZ).
Fifth Generation Capabilities
Since 2008 the PRC has worked to design and manufacture fifth generation concepts, both for its own use and to sell on a global scale. Two companies in China have worked on designs: the Chengdu Aircraft Industry Group (J-20) and the Shenyang Aircraft Corporation (J-31). Both are subsidiaries of the state-owned Aviation Industry Corporation of China (AVIC). It is likely that the J-20 and J-31 will complement one another when integrated into the PLAAF’s arsenal. The J-20 is closer to becoming operational, with an inaugural test flight in 2011; it is expected to reach initial operating capability (IOC) by 2018. Because both jets are still in prototype stage, their exact capabilities are not certain. However, it is speculated that the J-20 will provide a long-range strike system capable of reaching anywhere in the Western Pacific region, and incorporate a stealth design; the first of its kind in the PRC. In a conflict, the J-20 would likely be deployed in air-to-air combat with the mission of limiting the enemy’s radar coverage and strike range. The J-31 could be a potent complement to the J-20, similar to the planned U.S. partnership of the F-22 and F-35. While the J-20 is expected to possess superior dogfighting abilities, the J-31 will be “the perfect fighter for the PLA to carry out anti-access area-denial (A2AD) strategies in the Western Pacific”. The J-20 is slightly faster, with a maximum speed of Mach 2.5compared to Mach 2 for the J-31. Both sport a combat radius of approximately 2000km (1242 miles).
U.S. officials believe that the J-31 will immediately match or exceed the capabilities of U.S. fourth generation fighters such as the F-15 Strike Eagle and F/A-18 Super Hornet, and could possibly even compete with the F-22 or F-35. But this would largely depend on several factors including the quality of Chinese pilots, the quantity of fighters produced, and the reliability of radar and other equipment on board. In late 2014, AVIC President Lin Zhouming made an even bolder prediction, saying, “When [the J-31] takes to the sky, it could definitely take down the F-35. It's a certainty.” Even if neither of the Chinese fighter jets is entirely up to par with U.S. fifth-gens, they still could drastically change the dynamic of both a conflict with the U.S. or a scenario such as an invasion of Taiwan.

Saudi Arabia Set to Buy Four Lockheed Martin Freedom-Class Variants in $11.25B Deal
Four Lockheed Martin Freedom-class ship variants are set to form the backbone of the Royal Saudi Navy’s Eastern Fleet as part of a $11.25 billion foreign military sales case presented to Congress on Monday.
The ships and the subsequent systems, weapons and munitions are the centerpiece of the long awaited Saudi Naval Expansion Program II (SNEP II) — the estimated $20 billon program to refresh the aging U.S.-built Saudi fleet operating in the Persian Gulf, according to a State Department notification issued on Tuesday morning.
“This acquisition will enhance the stability and maritime security in the sea areas around the Arabian Peninsula and support strategic objectives of the United States,” read the notification. “The proposed sale will provide Saudi Arabia with an increased ability to meet current and future maritime threats from enemy weapon systems. The Multi-Mission Surface Combatant ships will provide protection-in- depth for critical industrial infrastructure and for the sea lines of communication.”
Unlike the Freedom Flight 0 Littoral Combat Ships, the Saudi ships do not appear to have the modular mission package ability and will be rather a more traditional multi-mission model.
“We are very pleased to have the opportunity to provide the Kingdom of Saudi Arabia with four multi-mission surface combatants (MMSC), based on the Freedom-class Littoral Combat Ship,” read a Lockheed Martin statement provided to USNI News.
“We look forward to working with both navies in developing a low-risk, cost effective approach that delivers value back to the customers.”
Lockheed as presented several sizes of the Freedom for foreign sales and is yet unclear what the final tonnage of the Saudi variant will be.

Russian Salut Continues To Upgrade AL-31F
According to the Salut Gas Turbine Research and Production Centre’s Director General Vladislav Masalov, the company manufactured about a hundred AL-31F turbofans in several variants in 2011. Over 75% of them, in the AL-31FN version in the first place, were exported. The rest were made for the Russian Defence Ministry. To fit the aircraft in service with the Russian Air Force, the company has for several years supplied AL-31F Series 42 engines upgraded by the in-house design bureau and known as AL-31F-M1.
The AL-31F-M1 passed its official trials in 2006 and has been ordered by the Defence Ministry since 2007 to equip Sukhoi Su-27SM fighters. Last year, Salut shipped another batch of engines of the type, which were used for fitting the Su-27SM(3) fighters delivered to RusAF under the contract signed in 2009. A decision in principle was taken to fit the RusAF-ordered Sukhoi Su-34 bombers with Salut-built AL-31F Series 42s. Unlike the baseline AL-31F, the upgraded engine has an advanced enlarged-diameter fan (924 mm) and an automatic control system with a digital integrated governor, which has increased the thrust up to 13,500 kgf and extended the service life.
The next stage of the Salut-conducted upgrade is to become the AL-31F-M2 engine, which thrust in special mode will increase to 14,500 kgf and the service life to 3,000 h or more.
Early this year, Salut hosted a meeting of the scientific and technical board attended by personnel of the Sukhoi design bureau, Lyulka scientific and technical centre (an affiliate of NPO Saturn JSC), United Aircraft Corporation and United Engine Corporation. The board met to consider the results produced by the development work on upgrade the second-stage AL-31F (AL-31F-M2). All work pertinent to the second stage of the engine’s upgrade is on schedule. To date, the engine has completed its special bench tests in Central Institute of Aviation Motors thermal vacuum chamber, which have proven the feasibility of a static thrust of 14,500 kgf and the manufacturer’s performance ratings. The upgraded engine has a 9% increase in thrust in flight modes over the AL-31F-M1.
“The upgrade of the AL-31F engine does not involve modifying its dimensions and is aimed at retaining the feasibility of re-engining the whole of the Su-27 aircraft fleet without extra modifications to the airframe or engine nacelles”, Salut General Designer Gennady Skirdov said.

Russia Reportedly Looking To Remove Itself From Internet
Russia has reportedly run tests to see if it can remove itself from the World Wide Web to stem the flow of information to and from foreign countries, according to a top industry official.
Experts told the UK Daily Telegraph the tests were run to prepare for an information blackout in case of a potential domestic political crisis. The attempt to cut Russia from the Internet has stoked fears about the Kremlin stripping Internet freedoms from its citizens.
Andrei Semerikov, general director of Russian Internet provider Er Telecom, told the newspaper it was ordered by the ministry of communications and Russia’s national Internet regulator, Roskomnadzor, to block traffic to foreign communications channels by using DPI, a traffic control system.
The goal was to see if Russia’s Internet could continue to function even though it was cut off from the global Internet.
Russian officials denied any experiment took place. A spokesman for Roskomnadzor told The Telegraph “there was not such experiment.” Another spokesman told Russian newspaper RBK that Semerikov’s comments were taken out of context.
However, RBK reported that a similar test to cut Russia from the World Wide Web was conducted last July. The FSB, Russia’s defense ministry and interior ministry collaborated with the country’s telephone operator to see if a national intranet made up of certain Russian domain names could survive if cut off from other parts of the web.
Russian president Vladimir Putin reportedly ordered the test to assess the country’s Internet capabilities should Western sanctions cut off the country from the Internet. The test resulted in a move to build a backup infrastructure to ensure the Internet could continue to operate.
Andrei Soldatov, an expert in Russian security services, told the UK Daily Telegraph the tests are a “pretext” and said the government is getting ready for the possibility of shutting down the flow of information from the outside world.
Experts told the UK Daily Telegraph the tests were run to prepare for an information blackout in case of a potential domestic political crisis. The attempt to cut Russia from the Internet has stoked fears about the Kremlin stripping Internet freedoms from its citizens.

China May Deliver 300 of Type 99 Main Battle Tank to Pakistan
According to reports, china may deliver a total of 300 of Type 99 Main Battle Tank to Pakistan. Pakistan is already testing the Type 99 Main Battle Tank given the unsatisfactory performance of the VT-4 and Oplot-M. VT-4 is the export variant of the MBT-3000, while the Oplot-M is a Ukranian Tank. Pakistan is looking to upgrade its inventory of tanks in order to satisfy the needs of the armed forces from 2017 to 2025. After the successful testing of Type 99 Main Battle Tank, it will be decided which tanks will to acquire.
Defense experts have welcomed this new development with open arms. The Type 99 Main Battle Tank would serve as a cheap and ideal replacement for Pakistan Army’s fleets of T80UD, Al-Zarrar, Type 85, Type 69, and Type 59 MBTs. The fleets under Pakistan Army as of right now are quite old and can’t possibly create with a modern line of tanks in huge numbers. Type 99 Main Battle Tank was fielded by the Chinese People’s Liberation Army. It is a third-generation tank and a Chinese variant of the Russia T-72 MBT. Type 99 Main Battle Tank incorporates the autoloader, hull, the main gun and armor from the T-72 Russian MBT. If the deal between Pakistan and China on this front goes through, the Type 99 Main Battle Tank should also serve as an ideal opponent to the Indian T-90MS.

Rafale Most Expensive Acquisition- LCA Cheapest in Combat Category
Indian Defense Minister Manohar Parrikar had told the Indian air force that there weren't enough funds to expand the Rafale acquisition and that it must induct an improved version of the indigenous Tejas-Mark 1A.
"The IAF (air force) needs to have a minimum number of aircraft at all times. The LCA is our best option at this stage, given our resource constraints," the defense official said.
"The Rafale is our most expensive acquisition. The LCA is our cheapest in the combat category."
Modi pushes 'obsolete' made-in-India plane on reluctant military
NEW DELHI: India's government has turned down its military's request to expand the acquisition of 36 fighter planes from Dassault Aviation SAto plug vital gaps, officials said, nudging it to accept an indigenous combat plane 32 years in the making.
Indian Prime Minister Narendra Modi's decision, in line with his Make-in-India policy to encourage domestic industry, is a blow for not only the French manufacturerbut also others circling over the Indian military aviation market worth billions of dollars.
The push for India's struggling Tejas light combat aircraft(LCA) also comes at a time when the Indian Air Force(IAF) is at its weakest operational strength since the 1962 war against China, which is causing anxiety within military circles.
Since it took over last year, the Modiadministration has repeatedly said its overriding goal is to cut off the military's addiction to foreign arms which has made it the world's top importer.
The air force wanted the government to clear an additional 44 Rafale medium multirole aircraft on top of the 36 that Modiannounced during a visit to Paris this year that are to be bought off-the-shelf to meet its urgent requirements.
But a defense ministry official said that Indian Defense Minister Manohar Parrikar had told the Indian air force that there weren't enough funds to expand the Rafale acquisition and that it must induct an improved version of the indigenous Tejas-Mark 1A.
"The IAF (air force) needs to have a minimum number of aircraft at all times. The LCA is our best option at this stage, given our resource constraints," the defense official said.
"The Rafale is our most expensive acquisition. The LCA is our cheapest in the combat category."
India's air force says its requires 45 fighter squadrons to counter a "two-front collusive threat" from Pakistan and China. But it only has 35 active fighter squadrons, parliament's defense committee said in a report in April citing a presentation by a top air force officer.
