China Developing Arsenal Ship

Reports claim there has been substantial design work and concept proofing for a new underwater arsenal ship in China. A leading chinese naval engineer Professor Dong Wei Cai continued to work on a key aspect of the arsenal ship design: the high-speed wave hydroplane up until his recent death.

There are two concepts in circulation:
1. a high-speed warship with much of its hull submerged but otherwise has a functional superstructure with defense weapons and radar
2. other is almost completely submerged arsenal ship with two conning towers.

Both ship designs could displace roughly about 20,000 tons at full load.

These warships could carry hundreds of guided missiles.

The arsenal ship would have most of its hull inherently submerged, with only the bridge and a few other parts of the ship above the waterline which reduce the radar cross section. This would be in situations where the ship is hiding or trying to protect itself.

China also working to add Hypersonic Warheads to Shorter Range Missiles

China has conducted seven tests of a hypersonic glide missile in recent years, six of which have been successful. While Beijing has acknowledged such testing, it was previously unknown that it is also working on a short-range hypersonic weapons development program for East Asian targets.

Hypersonic weapons are next-generation maneuvering strike vehicles launched at top of  ballistic missiles that travel at speeds of up to Mach 10, or 10 times the speed of sound. They maneuver and glide along the edge of space, making them very difficult for missile defenses to shoot down.

The United States and Russia have also been aggressive about developing hypersonic strike capability. It is thought that Japan’s anti missile system could be made impotent if Beijing’s development of hypersonic weapons advances.

In Japan, the Patriot Advanced Capability-3 missile defense system has been deployed by the Air Self-Defense Force along with the Maritime Self-Defense Force’s Aegis destroyers equipped with Standard Missile-3 interceptors.

Taiwan has also deployed PAC-3 surface-to-air guided interceptors, while South Korea has decided to deploy the advanced Terminal High Altitude Area Defense (THAAD) anti ballistic missile system on its soil to better cope with North Korea’s missile threats.

India might hit Pakistan, warns US Defence Intelligence Agency Chief

WASHINGTON: India might strike Pakistan in order to teach him a lesson over the increasing cross border attacks, Head of the US Defence Intelligence Agency has informed the US Senate Armed Services Committee.

A senior intelligence official from the United States has warned that India is considering punitive actions against Pakistan.

“India has sought and continues to move to isolate Pakistan diplomatically and is considering punitive options to raise the cost to Islamabad for its alleged support to cross-border terrorism,” US Defence Intelligence Agency (DIA) Director Lieutenant General Vincent Stewart told the Senate Armed Services Committee on Tuesday.

The Indian army claimed yesterday (Tuesday) that it had destroyed several Pakistani posts across the LoC. However, the Pakistan Army has rubbished Indian claims.

China Test Fired New Missiles

China has conducted a number of weapons tests, which included the launch of a new missile type in the northeastern Bohai Sea close to the Korean Peninsula, the Information Bureau of China’s Ministry of National Defense announced on May 9.



Speculations about the missiles test fired range from
* a new variant of the intermediate-range DF-26 ballistic missile, the DF-26B.
* a new submarine-launched ballistic missile dubbed the JL-3.
* a DF-21D medium range ballistic missile.

China Developing Wing in Ground Effect Drone

China is developing a new drone that uses ground effect technology to skim the surface of the ocean, allowing it to fly just eighteen inches off the water. The unmanned vehicle could be a challenging opponent for potential adversaries, some of whom would find it difficult to detect.




The new ultra-low altitude anti-ship unmanned system can fly as low as 50 cm above the sea, can reach a maximum altitude of 3,000 km, along with an endurance of 1.5 hours – depending on the flight profile. The maximum take-off weight (MTOW) is 3000 kilograms and can carry a 1000 kg load.

Google Probably has Over Ten Million Servers

Google data centers process an average of 40 million searches per second, resulting in 3.5 billion searches per day and 1.2 trillion searches per year.

Google was spending $20 billion per year on its data centers in 2014 and now is spending about $30 billion per year.

Google used 5.7 terawatt-hours of electricity Google consumed in 2015 which is about 1 gigawatt of power. If each server used 200 watts then Google had 5 million servers in 2015.
In 2017, Google power usage has likely continued to increase and Google has some very energy efficient servers. It is highly likely that Google has over ten million servers.

Google’s global data centers have been using atomic clocks for database synchronization for close to ten years. The Spanner project was revealed over five years ago. Google began the spanner project over ten years ago. The Spanner database uses atomic clocks and GPS for transaction timing.

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.

China showcases New-Generation Frigate and S26 Submarine

The China Shipbuilding Trading Corporation (CSSC) showcased its next-generation trimaran-hull frigate and the S26 air-independent propulsion (AIP) submarine (SSP) at the 2017 International Defence Exhibition and Conference (IDEX), which is concluding in Abu Dhabi.

The S26 SSP appears to be the AIP-equipped variant of the S20 diesel-electric submarine (SSK), which CSSC has been marketing for export since 2013.

Although the S20 SSK was not offered with AIP by default, a customer could opt for it separately. It was not clear if CSSC was offering an AIP of its own or if the end-user would have to acquire it separately. With the S26, CSSC is offering its Stirling AIP system (IHS Jane’s).

CSSC Timaran Frigate


In comparison to the S20 SSK, the S26 SSP has a heavier displacement (2,660-ton vs. 2,200-ton), is longer (79.5 metres vs. 66 metres) and slower at top speed (18 knots vs. 20 knots). However, CSSC did reveal the S26’s maximum diving depth and surface range at 300 metres and 14,816 km, respectively.


Russia Planing To Test Fire Rocket Mounted Zircon Hypersonic Missile

In the spring of 2017, Russia may test a rocket mounted Zircon Hypersonic missile for the first time. The launch is said to be conducted within the scope of the global non-nuclear deterrence strategy.

The source did not specify the carrier, from which the missile was to be launched.

Zircon mounted Hypersonic Missiles are planned to be used on Yasen-M nuclear submarines, as with the well as with the Husky's Submarines and some surface ships.

Hypersonic speed is Mach 5 or faster. Mach 1 is the speed of sound which is about 300 meters per second, or 1,224 km/h.

The Zircon missile was designed for the Russian Navy at NPO Machine Building (Reutov, Moscow region). The company also develops advanced warheads for intercontinental ballistic missiles known as "Object 4202."

The range of the missile will be about 500 km, whereas the speed of the new missile is said to reach Mach 5 or six.

Zircon missiles can be used as armament for surface warships and nuclear-powered submarines, as well as aircraft and coastal mobile missile systems. It is believed that Onyx and Zircon missiles are designed to implement elements of the concept of strategic non-nuclear deterrence.
