鱼10果然牛啊

低速搜索时约28节，中速40节，高速至少55节……无级变速（不会咔嗒一下从一个速度段直接窜到另一个速度段，而是流畅滑顺的过渡，噪音和排放小）。射程60KM。

典型目标是潜艇、大型舰艇编队等等……

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)

IMHO, the body of the 'mystery torpedo' looks kinda like the DM2-A4...

This Friday, March 13, 2015 will remain an important date for the Cayman Marine who becomes a combat helicopter ASM in its own right following the statement by the General Staff of the Navy of an initial operational capability shot from the MU90 torpedo.

This is a major milestone for the torque capability FREMM / Cayman that can now "treat" even more lengthens the latest underwater threats independently.

Images from Chinese military issue websites indicate the Kongjing 500 (KJ-500) airborne early warning and control (AEW&C) aircraft has started to enter service with the People's Liberation Army Air Force (PLAAF).

While images of the KJ-500 in the PLAAF paint scheme first appeared in late 2014, the first image of one with an official serial number (30471), confirming its service entry, did not appear until 18 March.

First seen in early 2013, the KJ-500 is based on the Shaanxi Aircraft Corporation (SAC) Y-9 four-turboprop transport combined with a fixed phased-array radar developed by the Nanjing Research Institute of Electronic Technology (NRIET, or 14th Institute).

Chinese internet sources suggest that while the KJ-500 is smaller in size, electronic advances enable its radar to be as capable as NRIET's fixed array for the KJ-2000 AEW&C system that is fitted to an Ilyushin Il-76 platform. In January 2013 Chinese television reported this radar could track 60 to 100 targets simultaneously out to 470 km.

The KJ-500 radar's three arrays are apparently the same size and contained in a saucer-shaped dome with an apparent satellite communications antenna in the middle. Other imagery indicates SAC considered but rejected a teardrop-shaped dome that would have allowed for larger side-looking arrays. The KJ-500 also features two passive electronic intelligence arrays.


The KJ-500 apparently will succeed production of the KJ-200 AEW&C system, which uses a linear phased-array radar that is strikingly similar to the Saab Erieye radar but that allows only for a 240° field of view.

Navy to get 3 new nuclear subs

China Unveils Three New Nuclear-Powered Attack Submarines

The Chinese Navy is preparing to commission three new, nuclear-powered attack submarines with a vertical launching system able to fire supersonic anti-ship missiles, a report from China Daily said.
The China Central Television showed satellite pictures earlier this week of the three submarines anchored at an unidentified port claiming that the new submarines are China’s most advanced Type-093G attack submarines.
“The Type-093G is reported to be an upgraded version of Type-093, China’s second-generation nuclear-powered attack submarine, which entered active service several years ago. With a teardrop hull, the submarine is longer than its predecessor and has a vertical launching system,” according to the China Daily report.
The Chinese navy’s website said the new variant is engineered to reduce noise, improve speed and mobility and fire China’s latest YJ-18 supersonic anti-ship missile, according to the report.

The Y-8Q will become a significant part of China's emerging ASW operations. Its 5,000km range, wide sensor and weapon range and massive payload will exponentially increase Chinese security against enemy submarines off its coasts and into the East and South China Seas. When combined with other ASW assets, such as underwater drones, missile launched torpedoes and sonar towing Type 065 corvettes, it could make current and planned regional investment into submarines by China's neighbors more of a risky proposition.

quote:

The Y-8FQ is based on the Y-8 Transport aircraft by Shaanxi Aircraft Company, equipped with four WJ-6C turbofan engines with 6-bladed propellers. The tail of the plane has been modified to improve handling at low speed and low altitude as request by Maritime Patrol Aircrafts mission profiles, when on ASW missions. On such mission the MPA would use its MAD (Magnetic Anomaly Detector) boom to detect submarines. This boom is clearly noticeable at the tail of the Y-8FQ.

From the picture above, we can note that the Y-8FQ is fitted with a chin radome probably housing some kind of maritime surveillance radar. It is also fitted with an Optronics turret and several antennas both at the top and at the bottom of the fuselage. Finally, note the weapon bay doors just in front of the main landing gear, as well as the large bulbous window at the rear for visual observation.

All in all this new Y-8FQ Cub/High New 6 Maritime Patrol Aircraft has all the attributes of a capable MPA like the P-3 Orion, Atlantique II or IL-38. The first Y-8FQ MPA will likely be operated by 2nd Naval Aviation Division 6th Regiment Dalian-Tuchengzi.

In 1986, two engineers from Beijing's Ministry of Aviation visited Lockheed. They could not speak very much English, and the Lockheed-Georgia sales person who met them could not speak Chinese. So for half a day, they did a point-and-grunt tour until they were lucky enough to find a Lockheed employee who could speak Chinese. The Chinese wanted to purchase Lockheed wind tunnel testing on the Y-8 in order to address the stall problem.

As a result of these wind tunnel tests, conducted in 1986, Lockheed was given a contract to do a flight test series on the Y-8. Lockheed was told that flight test data was not provided by the Soviets when they helped China build the Y-8 factory. The flight test series was flown by Lockheed test pilot Hank Dees. Hank had flown the test flight series for the Lockheed L-1011 and later for China's Y-12 in Harbin.

During this flight test series, Hank Dees flew the aircraft to stall speed and taught Chinese pilots how to anticipate a stall in order to prevent letting the aircraft go inverted. As a result of this test flight series, Chinese pilots started to use the 45 degree flap position.

Lockheed's motive for doing flight tests was to demonstrate that China would be better off buying the C-130 rather than trying to improve the Y-8. China did buy C-130's, but the flight test series actually demonstrated that the Y-8 was a more capable aircraft than previously believed.

In the late 1980s, Lockheed Martin, the American manufacturer of the C-130 Hercules, helped China to develop a pressurized cabin for the passenger version of Y-8, resulting in two versions: the first had half of the cabin pressurized and later, the second version in which the complete cabin was pressurized.

In 2001 and 2002, new consulting arrangements between Antonov and Shaanxi resulted in modernized redesigns to the Y-8's wing and fuselage. As a consequence the redesign allows the Y-8's fuel capacity to be increased by 50 percent.

The USN's X-47B autonomously refuels in-flight from a KC-707:

When you consider that this UAV is not only unmanned, but is actually tanking autonomously, the real amazement should set in. Coming to a USN carrier near you! The Navy has already made the statement that it has already purchased it's last manned fighter. I can't wait to see their next, bigger, more capable version of it, the X-47C! The future IS now!

Yes, you are right, this is fantastic. I marvel at technology. But call me sentimental - with the removal of a pilot, I think we have lost something here.

Don't get me wrong, I see all the advantages - from safety, cost and training to the limitations of human pilot, but who will be tomorrow's aces? Who will be tomorrow's Reb Barrons?

I know war is not romantic, but many of our heroes come out of combat. Will we give great honor to a pilot in a trailer somewhere in Nevada? Probably, but it still misses something for me.

I know it is the way of the future, but having robots fight and kill for us seems to ring of some apocalyptic stories we've heard. At least when there is human loss in war, it makes the sides push harder to win and bring it to an end; or it makes a side cede to the other.

I do not say all this to aggrandize war and combat, nor am I unhappy that we have such technology. It just seems like something will be lost when the last fighter pilot hangs up his helmet.

Well, I'm one of those weird types that is all about numbers and hard cold math. The advantages outweigh the disadvantages, therefore it's a foregone conclusion. We do the drone thing. Is it stoic and glamorous to fly a drone? Perhaps not. But is it the way that the future is headed? Yes, absolutely. Times change.
