My comment:
(a) CPGS: Conventional Prompt Global Strike
(b) The quotation takes me by surprise.
(c) X-51A
(i) Chris Haddox, The X-51A Soars to New Heights. Boeing, May 1, 2013 www.boeing.com/boeing/Features/2013/05/bds_x51_05_03_13.page
contains two clips:
(A) a video whose ending states, "The X-51A WaveRider program is a joint program between Boeing, Air Force Research Laboratory, Darpa and Pratt & Whitney Rocketdyne."
(B) an animation.
(ii) As far as I can recall, I did not know of the May 1, 2013 testing of X-51A until today. What I did know was
X-51 Waverider: Hypersonic jet ambitions fall short http://www.bbc.com/future/story/ ... mbitions-fall-short
Sharon Weinberger, X-51 Waverider: Hypersonic Jet Ambitions Fall Short. BBC, Aug 15, 2012 http://www.bbc.com/future/story/ ... mbitions-fall-short
("The most recent test flight ended in failure on Tuesday when a faulty control fin caused the US Air Force X-51 Waverider jet to lose control and crash into the Pacific Ocean. The missile-like vehicle - powered by a supersonic combustion engine known as a scramjet - was dropped from a B-52 bomber off the coast of southern California It was supposed to be propelled by a solid-rocket booster, then ignite its scramjet engine to reach speeds of up to Mach 6. In the end, the test flight lasted just 31 seconds")
BBC did not report the May 1, 2013 testing (I just googled and found so).
(iii) Boeing X-51

Quote:
"The X-51 is named 'WaveRider' because it uses its shock waves to add lift.
"On May 1, 2013, the X-51 performed its first fully successful flight test on its fourth test flight. The X-51 and booster detached from a B-52H and was powered to Mach 4.8 (3,200 mph; 5,100 km/h) by a booster rocket. It then separated cleanly from the booster and ignited its own engine. The test aircraft then accelerated to Mach 5.1 (3,400 mph; 5,400 km/h) and flew for 240 seconds until running out of fuel and plunging into the Pacific Ocean off Point Mugu; this test was the longest air-breathing hypersonic flight. Researchers collected flight telemetry data for 370 seconds. The test signified the completion of the program. The Air Force Research Laboratory believes the successful flight will serve as research for practical applications of hypersonic flight, such as a missile, reconnaissance, transport, and air-breathing first stage for a space system."

(c) I can not find in the Web anything related to "在10月间成功测试了设计这种武器技术飞行环境的战斗部."
(d) There are two additional hypersonic vehicles (SR-72 and Falcon HTV-2, both of Lockheed Martin). See
"For the past several years, Lockheed Martin Skunk Works® has been working with Aerojet Rocketdyne to develop a method to integrate an off-the-shelf turbine with a supersonic combustion ramjet air breathing jet engine to power the aircraft from standstill to Mach 6. The result is the SR-72 that Aviation Week has dubbed 'son of Blackbird'
"SR-72 is not the first hypersonic Skunk Works® aircraft. In partnership with the Defense Advanced Research Projects Agency, engineers developed the rocket-launched Falcon Hypersonic Technology Vehicle 2 (HTV-2).

("A vehicle penetrating at high altitude and Mach 6, a speed viewed by Lockheed Martin as the “sweet spot” for practical air-breathing hypersonics")
(ii) The supplied link to Lockheed Martin's "Falcon Hypersonic Technology Vehicle 2" offers little information.
