PLA AEW&C, SIGINT, EW and MPA thread

New year's greeting from the airborne early warning radar R&D team of CETC(China Electronics Technology Corporation)

Yes, they have an E-2D model.

Do you have any information on detection ranges for the new KJ-3000s? E-2Ds evidently have a range around 600-800km vs 1 dbsm.

Lol we don't even have any realistic or reliable specs for KJ-2000/200/500, what do you think the chances are that we have anything resembling potentially accurate specs for a new AEW&C that has so far only been rumoured with little to no information known about it?

Interesting world map projection. I guess it puts China close to the middle without cutting the Americas in half.

Well.. thats the world map orientation usually used in East Asia. Emphasis is on the Pacific instead of the Atlantic. It's the same projection used back in my school days in the 1970s-80s in Malaysia and Singapore.

Yep, nothing weird or interesting or exciting about that map. Naturally, every nation wants to put itself in the center of attention when making a map. So what you are looking at would be typically how a world map would look like in eastern Asian nations, with Asia in the center. A world map from a European nation would put Europe in the center, just like Americas placed in the center on an American made world map.

Do American maps really have the Americas in the longitudinal centre? I'm not sure I've ever seen such a map before.

In Australia we usually use a projection centred on the Greenwich Prime Meridian as seen

. Although I am familiar with the controversy over differing projections (e.g. the Mercator projection making Africa appear far smaller than it really is), I had never considered a map with a differing longitudinal centre before.

Note that it's impossible to place the Americas in the absolute center without splitting Europe and Asia in half. What you see would be the best attempt to place Americas at the center.

If you scroll down a little, you will see a world map that they are selling. It actually splits part of Siberia in half in an attempt to move Americas a little more to the center (actually, they draw the part of Siberia and Alaska twice at each corner).

But that is the standard projection placing Europe, not America, at the longitudinal centre, derived from British and French practice in the 19th century. Again see Greenwich Prime Meridian at which the map is longitudinally centred.

I see it. That seems a little odd. There are also two New Zealand's, lol.

A rotary carrier based awascs is very interesting

E2D advanced unit is also under going aerial refueling tests

Well this is odd.

US, Chinese aircraft in 'unsafe' encounter in South China Sea
By: Mike Yeo, February 9, 2017
MELBOURNE, Australia — The U.S. Pacific Command detailed what it called an "unsafe" close encounter between a U.S. Navy P-3 Orion aircraft and a Chinese aircraft Wednesday.

The two planes reportedly flew within 1,000 feet of each other in the general vicinity of the contested Scarborough Shoal in the South China Sea.

Maj. Rob Shulford, a spokesman for PACOM, told Defense News that “on Feb. 8 (local), an interaction characterized by U.S. Pacific Command as 'unsafe' occurred in international airspace above the South China Sea between a Chinese KJ-200 aircraft and a U.S. Navy P-3C aircraft.”

He also said that "the U.S. Navy P-3C was on a routine mission operating in accordance with international law," adding that the “Department of Defense and U.S. Pacific Command are always concerned about unsafe interactions with Chinese military forces."

There have been no other details about the relative flight paths of both aircraft at the time of the encounter, which has been described as “inadvertent,” although other reports said that the American P-3 had to alter course to avoid an aerial collision.

The Chinese aircraft involved has been identified as a Shaanxi KJ-200 Airborne Early Warning aircraft, which suggests this was unlikely to be an intercept of the P-3 by the Chinese.

The KJ-200 carries a phased array radar inside a long, rectangular housing mounted on struts on top of its fuselage. The aircraft is used by both the People’s Liberation Army Air Force and the air arm of the People’s Liberation Army Navy, or PLAN, to provide air surveillance.

It is unclear to which branch of China’s armed forces the aircraft involved in this latest encounter belongs, although PLAN KJ-200s have been known to operate from air bases on China’s southern Hainan Island, 530 miles from Scarborough Shoal.

The aircraft are usually on temporary rotations to Hainan, being normally assigned to the PLAN’s 2nd Air Division, 4th Regiment based at Laiyang in Shandong Province, northern China.
