The VOA report is erroneous in identifying the flying machine as 猎鹰.

Guy Norris, U.S. Hypersonics Could Hinge On X-51 Tests. Aviation Week, Mar.
19, 2010.

("two long-awaited technology demonstrations starting with the imminent
first flight attempt for the X-51 Waverider, to be followed within a month
by the first flight of the Falcon HTV-2 hypersonic test vehicle")

My comment:
(a) Little wonder that the VOA report got confused.
(b) "The FALCON project includes [among others,
#] The Hypersonic Technology Vehicle-1 (HTV-1) — a test concept, originally
planned to fly in September 2007 now cancelled.
# The HTV-2 — to fly in 2009."

(c) Minotaur IV
http://en.wikipedia.org/wiki/Minotaur_IV
(an expendable launch system of four-stage rocket; Orbital Sciences
Corporation of Viaginia; currently its maiden flight--with Lite--is
scheduled for April 2010, to launch HTV-2)
(d) Captive carry

(e) GPS/INS

("use of GPS satellite signals to correct or calibrate a solution from an
Inertial Navigation System (INS)")
