ABOARD SHIP XIANGYANGHONG — Jiaolong, China's manned submersible, explored submarine turbidity currents in the South China Sea on Saturday.

With a maximum depth of 2,980 meters, Jiaolong was underwater for nine hours and 54 minutes in its seventh dive in the second stage of China's 38th ocean scientific expedition, which will last until May 13.

Three crew members in the submersible conducted surveys and sampling and measured environmental parameters. They brought back samples of sediment and seawater near the seabed as well as high-definition photos and video footage.

Xu Jingping, a professor with the Ocean University of China, said China started research on submarine turbidity currents, a major challenge in geoscience, relatively late.

"The dive helped us to obtain evidence of the topographic features and sediment of modern turbidity currents in northeastern South China Sea. It enriched our scientific understanding of canyon turbidity current in the region and provided key data and technical support for future research," Xu said.

The 38th oceanic scientific expedition started on Feb. 6. Jiaolong completed a dive in the northwestern Indian Ocean earlier this year as part of the first stage of the mission. It will also conduct surveys in the Yap Trench and the Mariana Trench in the third stage.

Satellite images reveal Chinese expansion in South China Sea

TEL AVIV, Israel — Imagery captured Monday from an ImageSat International (ISI) Eros B satellite indicates Chinese preparations for new land-based missile installations on an increasingly strategic island base in the South China Sea.

The high-resolution imagery, shown here for the first time, reveals recent changes in the layout of the People’s Liberation Army’s Yulin Naval Base at the tip of Hainan Island in the disputed Scarborough Shoal. In less than two months, the PLA deployed multiple missile launchers on the western side of the base, deployments that ISI imagery analyst Amit Gur has concluded are anti-ship missiles.

“The direction in which the launchers are facing leads us to believe these are shore-to-ship missiles,” Gur told Defense News.

He said that similar systems had shown up in satellite data about two years ago, but had been removed in recent months to accommodate infrastructure upgrades at the site. ISI's imagery from March 15 shows an empty plateau, but by May 8 the firm’s Eros B captured a clear image of newly paved infrastructure and multiple launch sites.

“They must have concluded renovation work, as the systems are clearly visible,” Gur said. “We just don’t know if they are new systems, or a [redeployment] of the ones that were stored during the renovation.”

Perhaps even more interesting, according to ISI, is progress taking place on Yulin’s eastern side. “We’re seeing the building of infrastructure that wasn’t there before and what looks like preparations for shore-to-ship missiles, just like on the western side,” company spokesman Gil Or said.

Gur noted that expansion of the Yulin base fortifies Beijing’s strategic triangle of forward bases with which to quickly project its power well beyond neighboring Vietnam and the Philippines.

There is no mention of Scarborough Shoal in the original text and there is no dispute over Hainan Island portion of the South China Sea.
What's your motive for inserting "Scarborough Shoal".

The article was most likely edited after the writer was informed of the obvious error. The writer motive is to create fear and mistrust of China's defense development by connecting it to the South China Sea issue.

American idiots, it's name is on it. Go home Yankee

The Sea of Japan does not belong to Japan.
The Philippine Sea does not belong to the Philippines.
The Indian Ocean does not belong to India.
And the South China Sea does not belong to China, just like how the East China Sea does not belong to China.

I wonder what would American supremacists do if China sends it's nuclear submarines and ACs beside destroyers to bay of pigs?

The US has experienced Soviet nuclear powered submarines going into the Caribbean Sea before. What happened was that the US built SONUS to detect the submarines and they followed the submarines with naval and air assets. The US never claimed the entire Caribbean Sea to belong to the US.

I like Japanese people, i hope you didn't take it aggressive my friend. In my Childhood i thought Samurayis are the bravest humans in the world but what i see now is completely a different thing. Japan is stabbing NK and China.

USA has not the right of such claim but it's military bases in Japan and S.K is an annoying thing to Japan's neighbors. Kick that bit** out of your motherland guys :lol:

ON BOARD SHIP XIANGYANGHONG — Jiaolong, China's manned submersible, conducted its ninth and final dive in the South China Sea Wednesday.

Jiaolong stayed underwater for nine and a half hours in its ninth dive in the second stage of China's 38th ocean scientific expedition, which will last until May 13.

The maximum depth of the dive was 1,897 meters in the Puyuan Seamount. Three crew in the submersible brought back samples of seawater from near the seabed, sediment, high-definition photographs and video footage.

The 38th oceanic scientific expedition started on Feb 6. Jiaolong completed a dive in the northwestern Indian Ocean earlier this year in the mission's first stage.

It will also conduct surveys in the Yap Trench and the Mariana Trench in the third stage. Named after a mythical dragon, Jiaolong reached its deepest depth of 7,062 meters in the Mariana Trench in June 2012.

What Makes New Chinese Sea-Skimming Combat Drone Perfect for South China Sea

Sputnik News

In-Depth Coverage

19:55 10.05.2017(updated 21:14 10.05.2017)

Pictures have emerged on social media of a new Chinese anti-ship drone that uses ground effect technology to fly at an extremely low altitude above the water.

The pictures show a flying vehicle with a set of forward canards and a pair of upward swept wings. The drone is painted in the blue camouflage of the Chinese Navy.

According to an article on Defense Blog, the new sea-skimming drone will be able to fly as low as 50 cm above the surface of the water. It can reach a maximum altitude of 3,000 meters and has an endurance of 1.5 hours. The drone has a maximum takeoff weight of 3,000 kilograms and can carry a 1,000 kg load.

In an interview with Sputnik China, Russian military expert Vasily Kashin said that the available information indicates that China is on the verge of creating a new type of weapon that would embody the anti-access and area denial (A2/AD) conception.

Kashin said that the drone can take off from the water and this is why it is well suited for deployment to China-controlled islets and facilities in the South China Sea. Unlike planes, the drone could be used even if airstrips on those islands are destroyed.

"Its index name begins with CH, by analogy with Rainbow-type combat unmanned aerial vehicles. Probable, the new drone was developed by the 11th academy of the China Aerospace Science and Technology Corporation (CASC)," Kashin suggested.

Media reports do not provide details on the drone's speed. Usually, ekranoplans cannot surpass 500-550 kph. The expert said that with a flight time of 1.5 hours the drone isexpected to reach up to 600 kph and to be able to fly at 1-6 meters above the water.

Kashin said that the drone has three main purposes. First, it is designed to deliver strikes at large surface targets. Second, it can be used for rapid torpedo attacks at long distances. Finally, the drone will be useful for isolating maritime areas. Due to its low altitudes, the drone will not be suitable for reconnaissance missions.

"Probably, for the first group of tasks it can carry a powerful warhead with a weight of up to 1,000 kilograms. In such a scenario, the drone is not reusable. It is slower than anti-shipmissiles. At the same time, its low flight altitude will allow for traveling slightly touching the surface of the water," the expert said.

Kashin also assumed that the unit cost of the new drone could be much lower than that of an anti-ship cruise missile, especially a supersonic missile, due to a cheaper design of its body and engine.

The expert also pointed out that China is also working on so-called swarming drone technology. This concept refers to the use of an autonomous group of drones, which can intercommunicate and distribute roles on a mission. Similar technologies were used in Russian-developed heavy-anti-ship missiles, such as the Granit and the Vulkan.

"In theory, despite its low flight speed, drones of the new type could operate in a group, distributing directions of attack between each other. Thus, they could breach the air defense of the enemy naval group. The drone could also be equipped with radio and electronic warfare devices and armored protection," Kashin said.

Moreover, according to Kashin's assumption, an attack by these new drones could be coordinated with the use of other weapons, including anti-ship cruise and ballistic missiles and combat aircraft.

The new drone can also carry torpedoes, which makes it a kind of reusable anti-submarine missile, Kashin added.

"In this scenario, the vehicle would fly to the target probable location area and drop a torpedo. Possibly, it could receive information on the target from an underwater monitoring system currently developed by China. It could also coordinate with anti-submarine aircraft," the expert said.

Furthermore, according to the expert, the new drone could hypothetically be used against ground targets, with the use of theChinese version of the Russian-made Shkval torpedo.
