【ワシントン＝佐々木類】米空軍が２５日、地球上のあらゆる場所を１時間以内に攻撃できる超音速航空機Ｘ５１Ａウエーブライダーの初飛行実験を行うことが分かった。巡航ミサイルをモデルとした無人攻撃機で、洞窟（どうくつ）に潜むテロリストや敵基地を軍事衛星の誘導で“奇襲攻撃”する２１世紀型の新兵器だ。２０２０年ごろの配備を目指す

Ｘ５１Ａは米ボーイング社などが０３年から開発に本格着手した。「通常即応グローバルストライク」（ＰＧＳ）と呼ばれるミサイル兵器の一種で、Ｂ５２戦略爆撃機に搭載。発射後、５万フィート（約１万５千メートル）の高高度まで上昇し、マッハ５（時速約６１２０キロ）で滑空する無人攻撃機だ。アフガニスタンの洞窟に潜むテロリストや、発射台に設置された北朝鮮のミサイル、イランの核関連施設を１時間以内に攻撃できる。
通常兵器による攻撃の所要時間は最大で９６時間かかるとされ、大幅な時間の短縮となる。

米空軍は２５日、天候が良ければ、カリフォルニア州エドワーズ空軍基地からＢ５２に搭載、南カリフォルニア海岸沖で５分間の飛行実験を行う。

実験は、米時間26日に行われ、マッハ6を出したそうです。
訳していられませんが、原文で記事を載せておきます。
一体、どこまでやれば気が済むのでしょう。
こんなものを作って...
「洞窟に潜むテロリスト」って、自軍のテロリストたちを攻撃するのかね？？
X-51 Waverider makes historic hypersonic flight

EDWARDS AIR FORCE BASE, Calif: An X-51A Waverider flight-test vehicle successfully made the longest supersonic combustion ramjet-powered hypersonic flight May 26 off the southern California Pacific coast.
The more than 200 second burn by the X-51's Pratt & Whitney Rocketdyne-built air breathing scramjet engine accelerated the vehicle to Mach 6. The previous longest scramjet burn in a flight test was 12 seconds in a NASA X-43.
Air Force officials called the test, the first of four planned, an unqualified success. The flight is considered the first use of a practical hydrocarbon fueled scramjet in flight.
"We are ecstatic to have accomplished most of our test points on the X-51A's very first hypersonic mission," said Charlie Brink, a X-51A program manager with the Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio. "We equate this leap in engine technology as equivalent to the post-World War II jump from propeller-driven aircraft to jet engines."
The X-51 launched at about 10 a.m. from here, carried under the left wing of an Air Force Flight Test Center B-52 Stratofortress. Then, flying at 50,000 feet over the Point Mugu Naval Air Warfare Center Sea Range, it was released. Four seconds later an Army Tactical Missile solid rocket booster accelerated the X-51 to about Mach 4.8 mach before it and a connecting interstage were jettisoned.
The launch and separation were normal, Mr. Brink said.
Four X-51A cruisers have been built for the Air Force and the (Defense Advanced Research Projects Agency) by industry partners Pratt & Whitney Rocketdyne and Boeing.
Air Force officials intend to fly the three remaining X-51A flight test vehicles this fall, Mr. Brink said.
Air Force officials currently plan to fly each on virtually identical flight profiles, building knowledge from each successive flight.
Hypersonic flight, normally defined as beginning at Mach 5, five times speed of sound, presents unique technical challenges with heat and pressure, which make conventional turbine engines impractical. Program officials said producing thrust with a scramjet has been compared to lighting a match in a hurricane and keeping it burning.
"This first flight was the culmination of a six-year effort by a small, but very talented AFRL, DARPA and industry development team," Mr. Brink said. "Now we will go back and really scrutinize our data. No test is perfect, and I'm sure we will find anomalies that we will need to address before the next flight. But anyone will tell you that we learn just as much, if not more, when we encounter a glitch."
Mr. Brink noted while development of the X-51A's engine and the test program are complex, controlling costs has been a key objective. The team has incorporated or adapted existing proven technologies and elected from the outset not to build recovery systems in the flight test vehicles, in an effort to control costs and focus funding on the vehicle's fuel-cooled scramjet engine.
Mr. Brink said he believes the X-51A program will provide knowledge required to develop the game changing technologies needed for future access to space and hypersonic weapon applications.
