China conducts first test-flight of stealth plane

very interesting, what will be the reactions I wonder....

China Military: Chinese Stealth Fighter "J-20" ( 2 ) 29/12/2010

Agree.

Flying such a thing and integrating it into a valid combat environment are some way different pairs of shoes.

Rattler

I thought it looked like a cheap copy of the F-22 but looking at the engines and and after burners I think the only thing out there with a bigger heat signature would be the sun.

Have a search on their Air to airmissile program, its here on WaT.
the airplane isnt so much a danger, but their missiles ( specially the latest types) are state of the art.
Some types are ( according to military technology) probably more advanced than ours ..........

Update on this issue, (source, Military Technology)

No simple copy and no surprise,

Similar to Sukhois T50(PAK FA) unveiled a year ago, whatever the new design is, has just now begun a process of system integration and tests.
These could easily take years.
While the front end of what the Chinese call Wei Long (Powerful dragon) looks like an F-22, it does not mean its a simple clone.
If one cannot resist "sinister" comparisations the J-20 prototype more likely resembles the ill-fated Russian MIG I.42 from 1999, featuring JSF like DSI optimised side intakes with bumps in the upper corners, a RAPTOR styled nose ans a onepiece canopy.
It features T50 like , all  moving out canted tailfins and ventral stabilising fins.
The later item is expected to be removed from future production models, once the flight control software further advances.
First disclosed to the public in 1997 by the US office of Naval intelligence to enter the service around the year 2015, the J-20 is what the CHinese call a 4th generation multirole fighter.
Overall performance of the J-20 is carefully thought to be superior to the Russian T50 but still inferior to the US F-22 ( electronics and supercruise)
As there was no official statement of acknowledgement before the first flight, speculations on the J-20s subsystems being built around an advanced FBW system fully integraded with the FADEC engine and the fire-control system around AESAtype 1475/KLJ5 radar remain.
The aircraft almost certainly features a glass cockpit, a wide angle holographic HUD and one single F-35 style colour LCD display with J-20 symbols shown at previous Zuhai shows.
Many of these subsystems have been tested on a J-10 or J-11 to speed up their development.

The Achilles heel......

Traditionaaly the Chinese were weak in high performance engine technology.
Hence the J-20 relies on powerplants directly from Russia or their Chinese derivatives.
It was rumoured earlier that the J-20 could initially be powered by two 13.200 kg/WS-10 class engines with TVC nozzles, while it was reported in november 2006 that a T/W10 17.000kg class turbofan (WS/15 enhanced thrust) would be under development for the J-20.
Reports named a supply of Salyut 99M2s or even T50s 117S to power the 2 prototypes., if the domestic engineprogrammes fails to meet the schedules.
The latest add-on to the hype were sightings that two types of jet-pipe nozzles were involved in the taxi-tests.
Like AL-31F and shorter and shinier ones pointing to the WS-10.
Maybe both prototypes are indeed ready, however the shape of the J-20s rear-end does not look definitive or stealthy.......

More striker than fighter,

The large high wing delta with upwards canards ( the only ones on a 5th generation fighter design) offers a lot of space for fuel and weapon bays.
The latter probably being the most spacious among the F-22, F-35 and the PAK FA.
They look large enoygh to house next generation ram-jet missiles.
The bigger the aircraft is (+20 m in length and +13 m in wingspan) , the more likely its payload and range are designed as a bomber/striker/standoff missile platform.
China is strategically interested in long range area-denial/ force projection.
This airframe looks consisted with a desire to project  force far beyond Taiwan and the Yellow Sea.
The size of the aircraft suggests it was designed as a multi-role fighter from the start, with the range and payload to serve as a striker.

I think so, its just a simple design.
It has many flaws specially with the engines and in no way its capable of even getting near the wests sophisticated electronics.
What worries me is that the Chinese have developed new air to air missiles which are very capable and in some cases even better than ours.
Their latest family of missiles of long range missiles has greater range than our AMRAAM, with a large fleet of such aircraft loaded with these new missiles they become a big danger.......
