(a) 美国权威武器问题专家、莱克星顿研究所(Lexington Institute)的劳伦.汤普森博
士(Dr. Loren Thompson)说:
“我不知道中国军方是否想到了这一点,那就是,盖茨访华期间歼-20的试飞无意之中
很可能给美国的军工企业助了一臂之力。
“美国人通常对中国事务不是特别留心,但是国防部长盖茨访华期间,有关中国的新闻
,大家都很留心。而这期间,中国试飞了众人之前都认为10年之内不可能研发出的战机
,立即吸引了所有人的注意力。
"这一回,中方彻底做到了美国国内没有人能做到的,那就是,让国会重新考虑是否应
当继续生产F-22战机。
(b) 汤普森说,美方最终是否决定生产更多的F-22,目前还不好说,但是,假如决定继
续生产F-22的话,那么,F-22的主要厂家、洛克希德-马丁公司(Lockheed Martin)一定
得感谢中方

My comment:
(a) This article discusses L and X bands, both of which belong in
microwave
http://en.wikipedia.org/wiki/Microwave
(Microwaves are electromagnetic waves with wavelengths ranging from as long
as one meter to as short as one millimeter, or equivalently, with
frequencies between 300 MHz (0.3 GHz) and 300 GHz; section 3 Microwave
frequency bands)
(i) mega: 10 to the 6
giga: 10 to the 9
(ii) How did the names L and X bands come about?

(b) Boeing 737 AEW&C

Wedgetail"; Introduced 2009)
(i) wedge-tailed Eagle

(largest bird of prey in Australia; an unmistakable wedge-shaped tail)
(c) The report states F-35 and F-22 "have a single 'chine line”' uniting
the forebody, upper inlet lips, and wing and canard edges with a curved
surface above that line and flat, canted body surfaces below it."
(i)
* chine (n: of Germanic origin):
"1: BACKBONE, SPINE
2: the intersection of the bottom and the sides of a flat or V-bottomed boat"
Both definitions are from www.m-w.com.

(ii) "The F-22's stealth design evolved from that of the F-117, with a
preponderance of flat, canted surfaces and a sharp cline line from the nose
to the wingtips."

(4) At Keio University in Tokyo, on Jan 14 defense secretary Robert Gates
gave a talk and held a Q & A session. He still thought Pres. Hu had not
known of the first flight test of J-20, which Mr Gates ascribed to
disconnect between military and civilians of China. Mr Gates said he did not
doubt Pres. Hu was in control. The pertinent portion of the transcript is
as follows.

Quote:
"Q: Thank you for today's opportunity. My name is Katsuya
Nagano from the Faculty of Law. Since you mentioned about outlining common
interests and sustaining and constructing the relationship with China, I
would like to ask you how you are looking at the current situation of China'
s civilian control over its army. And I ask this question because if truly
the civilian leaders, including President Hu, had no prior intel on the test
flights of the stealth fighters, then doesn't that represent the opaqueness
and the prominence of China's military, even within its own country, as it
is to the world? Would you remind sharing your perspective?
"SEC. GATES: This is an area where over the last several
years we have seen some signs of -- I guess I would call it a disconnect
between the military and the civilian leadership. We think that the
civilian leadership was not aware of the aggressive approach by Chinese
ships to the U.S.'s Navy ship Impeccable two or three years ago. We think
that -- our information is that the civilian leadership may not have known
about the anti-satellite test that was conducted about three years ago. And
as I indicated yesterday, there were pretty clear indications that they
were unaware of the flight test of the F-35 -- of the J-20, rather.
"I think that part of this, based on my experience, very
long experience in government, is -- can be explained by bureaucratic
mistakes. There have been more than a few occasions when the United States
military was conducting an exercise or carrying out an activity, and not
sensitive to the fact that a foreign visitor might be in Washington at the
same time. But on the whole, I do think that this is something that is a
worry.
"And one of the reasons why I have pressed so hard for there
to be a deeper, senior-level civilian-military dialogue with both civilian
and military representatives from both sides, from both countries is that we
have no forum right now on security issues or military issues that includes
senior civilians and military. And I think that, one of the questions I
was asked by the Chinese is, how do you differentiate this from all of the
other mechanisms for dialogue in the military-to-military arena? And my
argument back was this would be -- this is -- this would be the only one
where senior civilians and military are sitting together. And I think that
has great benefit.
"And I think that -- you know, I don't -- I don't question
the party's control of the PLA military or of the PLA. I have no doubts
about the fact that President Hu Jintao is in command and in charge. But I
just know from our own system at times there are disconnects between
military information flowing to our civilian leaders. Frankly, this has
been one of the benefits over the decades for the United States of the
National Security Council and the National Security Council staff, where the
civilian and military sides of the government are brought together
routinely and where information about military operations is shared in
detail not just with the White House, but also with the State Department.
So we are tied closely together.
"So I think there are opportunities in this dialogue to
advance that kind of civilian-military cooperation. And I think it would
also enhance military-to-military relationships.
