Russia developing Submarines that will use Composite Materials for hull and fire Hypersonic missiles

Russia will start building multi-purpose nuclear-powered submarines of the fifth generation in 2020. Companies of the United Shipbuilding Corporation (USC) are ready to start the work in 2020, when 885 Yasen project is completed. The Russian Husky submarine will be the follow up to the Yasen submarine.

The new submarines will be smaller and cheaper than their Soviet-designed predecessors. Indeed, there are indications that Moscow will be extensively leveraging automation technologies developed for the Project 705 Lira-class attack submarine—better known in the West as the Alfa-class—for the new boats.

Russian analysts estimate that the next-generation submarines will displace no more than about 6,000-tons. Which means that another Soviet innovation might make a comeback—liquid metal cooled reactors.

Russia will also incorporate composite structures in its next-generation follow-on to the Project 855M Yasen-class in the 2020s. The next-generation Russian nuclear submarines may use composite structures in an attempt to drastically reduce their acoustical signatures.

The new composite materials are still in testing, but Russia will test its first composite propeller design in 2018. “This is one of our institute’s most promising projects,” Polovinkin said. “This trend reduces vibration in the blades and increases the efficiency of the screw. These various effects will help improve the ship’s acoustic signature.”

For the time being, engineers are designing the look of future submarines. The performance of the subs remains a secret. According to developers, performance characteristics will depend on requirements from the navy.

It is worthy of note that Project 885 Yasen stipulates for the construction of seven multi-purpose nuclear submarines. The main submarine of the project - Severodvinsk - has already been passed into service.

Earlier, Pravda.Ru reported that Russia was planning to launch Zircon hypersonic missiles in the spring of 2017 from a sea-based carrier. The launches are said to be conducted for the implementation of the concept of global non-nuclear deterrence. Zircon hypersonic missiles will be installed on board Yasen-M submarines, Husky submarines, as well as a number of surface ships.

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.
