This confuse me. If there are lots of GX series for Y-8/9 and is still producing more, then what is the purpose for making Y-30?

For the next PLAN news update, some detective work yet again:

It is about the long-rumoured follow-on to the Yu-6 Heavy Weight Torpedo, reportedly designated the Yu-10.


It has, more or less, officially began with Bill Gertz usually alarmist, but rather reliable and authoritative article in the Washington Free Beacon about China "Testing a high-speed precision guided torpedo", accompanied with an ill-fitting photo of a Yu-7 LWT launch, dating November 14th 2013:

Due to the typical cryptic and inexpressive nature of Chinese military report on which this Gertz article was based, it was largely ignored by the western PLA-Watching community.

Then, in Summer 2014, Chinese state media leaked some pictures of an unknown and never-seen-before heavy-weight torpedoe, featuring what could be flank-array and pump-jet propulsion according to some analysts:

Again, people didnt know what to do with these pictures and quickly forgot about them.

But now, Chinese military forums are buzzing with people discussing recent insider leaks about certain "Yu-8, Yu-9 and Yu-10 torpedos" having finished their trials and are being introduced into service for quite some weeks now. What makes me doubtful at first is that noone has ever heard anything about these designations at all. But now, after consistent buzzing over multiple chinese military BBS boards, and lots of "Big Shrimps" (Chinese term for insiders/leakers with well known credentials) supporting these rumours with selective leaks, I began digging deeper into that matter.

Coincidentially, Feng, a long-time fellow Chinese military blogger writing for Information Dissemination and Defense News, and who has good reputation among professional military analysts who are often quoting his posts, has written an entry mentioning the ongoing ruckus about the new torpedo:

In his view, the Yu-10 rumours seem credible, as the PLAN has acknowledged the need for a high-speed and long ranged torpedo that is able to chase down the very fast and deep diving USN Nuclear Attack Submarines, as the previous Yu-3A and Yu-6 family arent all that suitable for that role anymore.

Today, a "Big Shrimp" has leaked the prospective stats of the Yu-10 heavy weight torpedo:

Translation:

Yu-10, the next generation heavy-weight torpedo and the successor of the current Yu-6, was long rumored to be roughly comparable to the Mk-48 Mod-6.

According to the big shrimp, the stats are following:

Low-speed not slower than 28 knots
Medium-speed 40 knots
Top-speed not slower than 55 knots

(possibly top speed still same as the Yu-6/Mk-48 i.e. 65 knots)

Smooth, level-less transition to the different speeds, resulting in low noise emission.

Maximum range of 60 km (at unknown speed)

"A team of researchers have developed a device that can make soldiers and vehicles disappear. Called the 'stealth sheet,' it's a paper-thin device that can obscure objects from being detected by a drone's infrared cameras."

I wonder how many Americans are working in China on military related technology?

Many.

For example, material science can provide technology with both military and civilian implications.

US intelligence report: China will have the world's most powerful naval gun ready for war by 2025

The warship-mounted electromagnetic railgun is expected to enter China's arsenal by 2025, according to sources with direct knowledge of a U.S. intelligence report.
Railguns have long appeared on Russian, Iranian and U.S. military wish lists as cost-effective weapons that give navies the might of a cannon with the range of a precision-guided missile.
China's railgun is capable of striking a target 124 miles away in under 90 seconds, according to the report.

China is currently testing the world's most powerful naval gun and people with direct knowledge of a U.S. intelligence report say it will be ready for war by 2025.

Railguns use electromagnetic energy instead of gunpowder to propel rounds, and China's is capable of striking a target 124 miles away at speeds of up to 1.6 miles per second, according to the report. For perspective, a shot fired from Washington, D.C., could reach Philadelphia in under 90 seconds.

Railguns have long appeared on Russian, Iranian and U.S. military wish lists as cost-effective weapons that give navies the might of a cannon with the range of a precision-guided missile.

The rounds used in China's railgun cost between $25,000 and $50,000 each, according to the intelligence assessment. Though not an exact comparison since the weapons have different technologies, the U.S. Navy's Tomahawk cruise missile has an estimated price tag of $1.4 million each.

China's railgun was first seen in 2011 and underwent testing in 2014, according to people who spoke to CNBC on the condition of anonymity. Between 2015 and 2017 the weapon was calibrated to strike at extended ranges, increasing its lethality. By December 2017, the weapon was successfully mounted on a warship and began at-sea testing, a feat no other nation has accomplished.

The U.S. Navy's railgun, years away from being operational, remains a classified system still in development under the Office of Naval Research.

China's sprint to develop a weapon of this magnitude comes on the heels of Beijing's recent deployment of missile systems to fortified outposts in the South China Sea.

The railgun coupled with the new coastal defense systems represents a significant addition to China's military portfolio in one of the most contested regions of the world.
