Washington
believes the J-20 could achieve an "effective operational capability" by
2018, and suggests the aircraft's role is as not a
fighter, but rather a long-range attack platform. It says engine
technology is the main challenge China will face in developing the J-20.
The US
Department of Defense's annual report to Congress, entitled "Military
and Security Developments Involving the People's Republic of
China," covers all aspects of China's defence modernisation.
"The J-20 will eventually give the People's Liberation Army Air
Force a platform capable of long-range, penetrating strikes into complex
air defense environments," said the report.
There
has been debate in defence circles as to the exact role of the J-20.
Some have speculated that it is intended as a direct rival
to the Lockheed Martin F-35 Lightning II fighter. Another popular theory indicates that it is designed specially
for long-range attacks against American aircraft carriers and other targets.
One table in the report underlined the speed and scale of PLAAF modernisation over the last decade.
In 2000, around 2% of its platforms were considered modern,
whereas today the number is 25%, with the force being filled out with
types such as the Sukhoi
Su-27 and Su-30, as well as the Chengdu J-10.
The report indicated that most of China's modernisation efforts
are aimed squarely at being able to prevail in a conflict over Taiwan,
which China views as a breakaway province.
China has a total of 1,680 fighter aircraft, of which 330 are
stationed within range of Taiwan, where they are opposed by Taiwan's
fighter fleet of just 388 aircraft. As for bombers and
attack aircraft, 160 are within range of Taiwan, out of a total
of 620.
"Currently, 490 aircraft could conduct combat operations against
Taiwan without refueling," said the report. "This number could be
significantly increased through any combination of aircraft
forward deployment, decreased ordnance loads or altered mission
profiles."
A war over Taiwan could draw in the USA. Recognising this, China
has developed new capabilities tailored for an "anti-access" strategy,
aimed at delaying or preventing American intervention.
