Russia May Sell China New Advanced Kalina-class Submarine Technology

Russia is developing a new advanced Kalina submarine class and may sell them to China, according to reports in Russia’s media.

Last week, the head of Russia’s Navy, Adm. Viktor Chirkov, announced that Russia would build new fifth-generation submarines dubbed the Kalina-class.

“Russia is currently designing a fifth-generation conventional submarine, dubbed Project Kalina, which will be fitted with an air-independent propulsion (AIP) system,” Adm. Viktor Chirkov said, according toRussian media outlets.

“Our industry promises to develop this AIP system by 2017 and build the first boat fitted with such a system by 2018,” he added.

The report did not specify what type of AIP technology would be used.

Kalina Class Submarine

Submarines equipped with AIP technologies offer significant advantages over conventional diesel-electric engines and even nuclear submarines. AIP systems allow submarines to stay submerged far longer than diesel-electric submarines, which must surface more frequently for oxygen, and thus give away their positions to potential adversaries.

On the other hand, submarines with AIP systems are much stealthier than nuclear-powered submarines, which must constantly run pumps to cool their nuclear reactors. This pump emits noises that can be used by adversaries to detect the submarine’s presence and location. Thus, AIP-powered submarines can stay submerged for long periods of time while remaining virtually silent.

A number of countries, predominately Western ones but also including ones like India, have acquired or are pursuing AIP-powered submarines. There is also speculation, including by the Indian government, that China’s Type 041 (Yuan-class) submarines—or at least some of the fleet—may be powered by AIP systems.

The development of the new Kalina-class submarines raises questions about a prospective submarine deal Russia is negotiating with China. As The Diplomat has reported before, Russia and China have long been in negotiations over Beijing’s desire to purchase four of Russia’s fourth generation Lada-class submarines. However, Russia’s decision to proceed with production of the fifth-generation Kalina-class submarines may mean that Moscow will not continue producing the Lada-class submarines (so far, only one Lada-class submarine, St. Petersburg, actually exists).

However, Voice of Russia reported soon after Admiral Chirkov’s announcement that Russian President Vladimir Putin will probably authorize the sale of the Kalina-class submarines to China. The Voice of Russia report—which does not appear to be available in English—was based on the assessment of Vassily Kashin, a senior research fellow from the Moscow-based Center for Analysis of Strategies and Technologies.

Thus, in no way has this been officially announced by the Russian government. Moreover, Moscow may be floating the idea simply as another way of pressuring the United States over its reaction to Russia’s annexation of the Crimea. Still, selling China the new submarines would further enhance Beijing’s growing undersea fleet, especially if China used the submarines to reverse engineer its own vessels based on Russia’s technology.

Pakistani JF-17 A Thunder OR A Blunder

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

Pakistani F-16s Shoot Down RAF Eurofighter Typhoons During Air Combat Exercises In Turkey

Pakistani pilots flying modernised versions of the 1970s-vintage F-16 Falcon fighter have beaten the RAF's brand-new Eurofighter Typhoon superfighters during air combat exercises in Turkey, according to a Pakistani officer. Analysis: The RAF Typhoon, formerly known as the Eurofighter, should nonetheless have been vastly superior in air-to-air combat whether BVR or close in within visual range (WVR). The cripplingly expensive, long-delayed Eurofighter was specifically designed to address the defects of its predecessor the Tornado F3 – famously almost useless in close-in, dogfighting-style air combat. The Typhoon was meant to see off such deadly in-close threats as Soviet "Fulcrums" and "Flankers" using short-range missiles fired using helmet-mounted sight systems: such planes were thought well able to beat not just Tornados but F-16s in close fighting, and this expectation was borne out after the Cold War when the Luftwaffe inherite

India Planned Attack On Pak Navy Mehran Base To Kill Chinese Engineers

The terrorist attack on Karachi's Mehran Naval Station on May 22 was conceived and launched by India with the primary objective of killing the Chinese engineers present there, a Pakistani newspaper has claimed, citing 'informed sources'. Four to six Taliban terrorists had entered PNS Mehran on May 22, destroying two maritime surveillance aircraft and killing ten military personnel during their 17-hour siege of the naval air base. "India is the only country in the region that feels troubled by the Pakistan Navy, which had awfully beaten the Indian Navy in Operation Dwarka of 1965. Since then, it has been an earnest desire of India to harm the Pakistan Navy but it was perhaps not possible on the battle front, hence it struck the PNS Mehran," The News quoted sources as saying.
