My comment:
(1) The VOA report is based on

John T. Bennett, DoD: U.S. Needs Stealthy Airlifter. Defense News, Mar. 8, 2010.
http://www.defensenews.com/story.php?i=4528377

(In fact, this is the only article/report that deals with this topic.)

Note:
(a) United States Special Operations Command
http://www.socom.mil
("The unified command for the worldwide use of Special Operations elements of the Army, Navy, and Air Force")

(b) blended-wing body (BWB)

Wikipedia for it differentiates blended-wing from flying-wing. This view is not widely shared. many web sites, including those from NASA, use them interchangeably. For example: "The BWB is basically a flying wing with the payload, i.e., passengers and cargo, enclosed in the thick, airfoil shaped, center section."
Leifur T. Leifsson and William H. Mason, The Blended Wing Body Aircraft. Virginia Polytechnic Institute and State University Blacksburg, VA, 2005.
http://www.aoe.vt.edu/research/groups/bwb/papers/TheBWBAircraft.pdf

(c) Airfoil
http://en.wikipedia.org/wiki/Airfoil
(the shape of a wing or blade (of a propeller, rotor or turbine [in this article: body) or sail as seen in cross-section)

(d) For swing wing, see variable-sweep wing
http://en.wikipedia.org/wiki/Variable-sweep_wing
("Typically, a swept wing is more suitable for high speeds, while an unswept wing is suitable for lower speeds, allowing the aircraft to carry more fuel and/or payload")

See also

Fact file: F-14 Tomcat. BBC (English), Dec. 11, 2002.
http://news.bbc.co.uk/2/hi/americas/2551409.stm
("These [two engines] propel the jet to more than twice the speed of sound. A distinctive feature of the F-14 is its computer-controlled swing wings: Swept forward to 20 degrees for slow speed manoeuvrability, back to 68 degrees at high speed.")

(e) I think teh article misspelled "Huessy." It should be Hussey.

(2) The VOA report quotes 鲁宾-约翰逊 as saying
(a) "美国政府买了一批俄罗斯的直升机."

See
Sharon Weinberger, Problems for U.S. Russian Helicopter Order. Aviation Week, June 1, 2009.
http://www.aviationweek.com/aw/generic/story_generic.jsp?channel=dti&id=news/IRAQ060109.xml
(A rush $322-million order for twenty two Mi-17s for Iraqi military now is over budget and nearly a year behind schedule.)

Note: Mil Mi-17
http://en.wikipedia.org/wiki/Mil_Mi-17

(b) "特种兵的威力往往决定于他们身边有多少先进设备,因此隐形运输机还必须能够空降或着陆运送各种精密的设备。"

I always wonder how American special op can function in alien lands, considering their facial features. It turns out that it also need instruments! How can it hide from the plain view?
