You've got the North Koreans and of course the Russians have not only been developing these intermediate range missiles but hypersonic and more strategic nuclear capable missiles as well.

有朝鲜，当然还有俄罗斯，他们不仅开发了这些中，还开发了超音速和更具战略核能力的。

Russia's military says the hypersonic missile can travel 2,000 kilometers and flies 10 times faster than the speed of sound, which makes it hard to shoot down.

俄罗斯军方表示，这种高超声速可以行2000公里，行速度是音速的10倍，这使得它很难被击落。

Russia's defense ministry says it's conducted a successful test of a hypersonic missile.

俄罗斯国防部表示，他们已经成功测试了高超音速。

Russia says it's acquired a new type of nuclear capable hypersonic missile.

俄罗斯称其已获得一种新型高超音速核。

North Korea tested a " hypersonic missile" , according to the country's state media.

据朝鲜官方媒体报道，朝鲜试射了一枚“高超音速”。

They said six hypersonic missiles had been shot down.

他们表示击落了六枚高超音速。

Government controlled media in North Korea said the missile was hypersonic, meaning it could fly as fast as 20 times the speed of sound and be nearly impossible to shoot down.

朝鲜政府媒体表示，这枚是超音速的，这意味着它的行速度可以达到音速的20倍，几乎不可能被击落。

Since then, we've actually flown aircraft or hypersonic vehicles that don't have pilots on board.

从那时起，我们实际上已经驾驶过没有行员的高超音速行器。

But we collected more hypersonic flight data than in 30 years of ground-based testing combined.

但我们也收集了比过去30年间地面测试总和还多的数据。

And it's pointed at the hypersonic glider.

用于拍摄特超音速滑翔。

The navy's engineers, it seems, are trying to revive an idea that might make hypersonic flight easier to achieve, but which was tested and then abandoned more than half a century ago.

看来，美国海军的工师们正试图复兴一种可能让高超音速行更容易实现的想法，但这种想法在半个多世纪前经过了测试，然后被放弃了。

The potential is around the world, you could literally have drones that would fly even hypersonic around the world and reduce the time from harvest of the organ to delivery to a patient two hours.

潜力无处不在，你真地可以拥有那种无，它们甚至可以在世界各地极超音速行，将从器官摘除到运送至病的时间缩短到两个小时。

Reports say Japan upgraded its cruise missiles and research on hypersonic weapons as it seeks to increase military spending to counter what Tokyo sees as the rising threat from China.

报道称，日本寻求增加军费开支研发，升级巡航和高超音速武器，以应对日方认为的“中国持续增长的威胁”。

Ukrainian President Volodymyr Zelenskyy called for comprehensive peace talks with Moscow in a video address released Saturday as Russia reported its first hypersonic missile strike on Ukrainian territory.

乌克兰总统弗拉基米尔·泽连斯基星期六发表视频讲话，呼吁与莫斯科进行全面和平谈判。与此同时，俄罗斯报告称，俄罗斯首次对乌克兰领土发动了高超音速袭击。

Meanwhile, Russia pounded cities and energy facilities across Ukraine with hypersonic missiles and drones in one of its biggest assaults of the conflict so far.

与此同时，俄罗斯用高超音速和无对乌克兰各地的城市和能源设施进行了猛烈攻击，这是迄今为止这场冲突中规模最大的一次袭击之一。

In addition to flying at extremely high speeds, hypersonic weapons are designed to move in ways that make them difficult to find and destroy in flight.

除了以极高速度行以外，高超音速武器的移动方式在行中很难被发现和摧毁。

Hypersonic is a term that relates to speeds of more than five times the speed of sound, also known as Mach 5.

超高音速是跟超5倍音速的速度相关的一个术语，这个速度也被称为5马赫。

Everhart said the time gained by using hypersonic spacecraft could keep the U.S. ahead in " the speed of war."

埃弗哈特说，利用高超音速船获得的时间可以让美国在“战争速度”方面保持领先。

And a meteoroid coming in at hypersonic speeds compresses the air in front of it a lot, heating it hugely.

一个流星体以高超音速来，会对它前面的空气进行很大的压缩，使其大幅升温。

You see, hummingbirds are not hypersonic, but they are maneuverable.

你知道，蜂鸟不是特超音速。但是操纵性很好。
