officail news: Y-20 will fly next year

[conworldus]

Mucho gracias, gringo.

Back to Stormfront for you.

He is not white man. He is an Asian who hates his own race, that's all. Oh I remember awhile ago he said that he only hates the Chinese government not the people, and now he is throwing racial slurs...

 

[conworldus]

Looks a bit like IL-76

All transports look alike sir. Please stop this "China copies again" silliness.

 

[Alpha_Fox]

Congratulations

ask any chinese members to translate not with google translator``its rubbish

be aware Google is peeking any sensible info and send it to CIA in no time. and watch out your gmail account.

Americans can not be trusted, Google especially.

Airborne laser??? When will it be inducted?

First of all, it is believed to have an airborne laser variant. That doesn't necessarily mean it must have an airborne laser variant.

Second of all, it is also possible that it will only be a testbed for the airborne laser. Extensive modifications to the airframe and sensors would have to be done in order to turn it into a full airborne laser platform.

My guess is that the airborne laser variant, if it indeed exists, will be fielded after 2012.

[ChineseTiger1986]

The WS-18 engine is just temporary, and the WS-20 engine is what really matter to us.

 

[madooxno9]

wooo....that's pretty big achievement .....

COnratzzzzz....

 

[UKBengali]

By 2020, China will have an arsenal of weapons second only to the US and then it will not be that far behind.

IMO, it is the best run large country on this planet at this period in history.

 

[Akasa]

There will be an airborne laser variant of the Y-20.

From MissileThreat:

China may have a laser weapon, similar in concept to the United States’ air-borne laser (ABL), which they can and may be deploying near Taiwan, in addition to their buildup of short range ballistic missiles. The Taipei Times cites Taiwanese defense sources that the laser cannon, with a range over 100km—again, comparable to the ABL—has been deployed in Fujian Province facing Taiwan, and that it could be used to disable military command and control systems. One defense official, however, noted that the cannon may only still be in development: “We tend to hope for the best but prepare for the worst. We would rather believe that China has already developed such a weapon and that we should start making preparations as soon as possible.” The Times notes that the United States and Israel have developed laser weapons—the ABL and the Tactical High Energy Laser (THEL)—but these are used as anti-missile defense systems. It is, however, plausible that the Chinese system is designed to have an anti-missile defense capability.

From Huitong:

It was also rumored that the aircraft might serve as the testbed for the Chinese airborne laser weapon prototype similar to American YAL-1 which is thought to be under development.

 

[AerospaceEngineer]

If an airborne early warning and control (AEW&C) with AESA Radar installed on it along with air refullers.....this will make it a hell of Monster.

Once Y-20 goes into production in late 2013 or early 2014. It will become the host plane for AEWC at once.

It will also become a tanker. Right now China has about 40 H-6 fuel tankers.

 

[no_koadsheding_plz]

Go China go.....

bhai go musharaf go ka suna tha,ya go china go kia cheez ha?
