发帖数: 27535 | 1 BRUSSELS (AP) — Chinese officials recently unveiled a new, high-tech
stealth fighter that could pose a significant threat to American air
superiority — and some of its technology, it turns out, may well have come
from the U.S. itself.
Balkan military officials and other experts have told The Associated Press
that in all probability the Chinese gleaned some of their technological know
-how from an American F-117 Nighthawk that was shot down over Serbia in 1999.
Nighthawks were the world's first stealth fighters, planes that were very
hard for radar to detect. But on March 27, 1999, during NATO's aerial
bombing of Serbia in the Kosovo war, a Serbian anti-aircraft missile shot
one of the Nighthawks down. The pilot ejected and was rescued.
It was the first time one of the much-touted "invisible" fighters had ever
been hit. The Pentagon believed a combination of clever tactics and sheer
luck had allowed a Soviet-built SA-3 missile to bring down the jet.
The wreckage was strewn over a wide area of flat farmlands, and civilians
collected the parts — some the size of small cars — as souvenirs.
"At the time, our intelligence reports told of Chinese agents crisscrossing
the region where the F-117 disintegrated, buying up parts of the plane from
local farmers," says Adm. Davor Domazet-Loso, Croatia's military chief of
staff during the Kosovo war.
"We believe the Chinese used those materials to gain an insight into secret
stealth technologies ... and to reverse-engineer them," Domazet-Loso said in
a telephone interview.
A senior Serbian military official confirmed that pieces of the wreckage
were removed by souvenir collectors, and that some ended up "in the hands of
foreign military attaches."
Efforts to get comment from China's defense ministry and the Pentagon were
unsuccessful.
China's multi-role stealth fighter — known as the Chengdu J-20 — made its
inaugural flight Jan. 11, revealing dramatic progress in the country's
efforts to develop cutting-edge military technologies.
Although the twin-engine J-20 is at least eight or nine years from entering
air force inventory, it could become a rival to America's top-of-the-line F-
22 Raptor, the successor to the Nighthawk and the only stealth fighter
currently in service.
China rolled out the J-20 just days before a visit to Beijing by U.S.
Defense Secretary Robert Gates, leading some analysts to speculate that the
timing was intended to demonstrate the growing might of China's armed forces.
Despite Chinese President Hu Jintao's high-profile visit to the United
States this week, many in Washington see China as an economic threat to the
U.S. and worry as well about Beijing's military might.
Parts of the downed F-117 wreckage — such as the left wing with US Air
Force insignia, the cockpit canopy, ejection seat, pilot's helmet and radio
— are exhibited at Belgrade's aviation museum.
"I don't know what happened to the rest of the plane," said Zoran Milicevic,
deputy director of the museum. "A lot of delegations visited us in the past
, including the Chinese, Russians and Americans ... but no one showed any
interest in taking any part of the jet."
Zoran Kusovac, a Rome-based military consultant, said the regime of former
Serbian President Slobodan Milosevic routinely shared captured Western
equipment with its Chinese and Russian allies.
"The destroyed F-117 topped that wish-list for both the Russians and Chinese
," Kusovac said.
Russia's Sukhoi T-50 prototype stealth fighter made its maiden flight last
year and is due to enter service in about four years. It is likely that the
Russians also gleaned knowledge of stealth technology from the downed
Nighthawk.
The F-117, developed in great secrecy in the 1970s, began service in 1983.
While not completely invisible to radar, its shape and radar-absorbent
coating made detection extremely difficult. The radar cross-section was
further reduced because the wings' leading and trailing edges were composed
of nonmetallic honeycomb structures that do not reflect radar rays.
Kusovac said insight into this critical technology, and particularly the
plane's secret radiation-absorbent exterior coating, would have
significantly enhanced China's stealth know-how.
Alexander Huang of Taipei's Tamkang University said the J-20 represented a
major step forward for China. He described Domazet-Loso's claim as "a
logical assessment."
"There is no other stronger source for the origin of the J-20's stealthy
technology," said Huang, an expert on China's air force. "The argument the
Croatian chief-of-staff makes is legitimate and cannot be ruled out."
The Chinese are well-known perpetrators of industrial espionage in Western
Europe and the United States, where the administration has also been
increasingly aggressive in prosecuting cases of Chinese espionage.
Western diplomats have said China maintained an intelligence post in its
Belgrade embassy during the Kosovo war. The building was mistakenly struck
by U.S. bombers that May, killing three people inside.
"What that means is that the Serbs and Chinese would have been sharing their
intelligence," said Alexander Neill, head of the Asia security program at
the Royal United Services Institute, a defense think tank in London. "It's
very likely that they shared the technology they recovered from the F-117,
and it's very plausible that elements of the F-117 got to China." | w**********g
