原文：

The United States announced Friday it has successfully tested an unarmed prototype of a hypersonic missile, a nuclear-capable weapon that could accelerate the arms race between superpowers.

The Pentagon said a test glide vehicle flew at hypersonic speeds-more than five times the speed of sound, or Mach 5-to a designated impact point.

The test followed the first joint US Army and Navy flight experiment in October 2017, when the prototype missile demonstrated it could glide in the direction of a target at hypersonic speed.

The military is planning future experiments to expedite the fielding of hypersonic warfighting capabilities in the early- to mid-2020s.

中譯：

美國週五宣布，美軍已成功測試一款無武裝的極音速飛彈原型，這是一種可搭載核武並能加速超級大國之間軍備競賽的武器。

美國國防部表示，測試彈體以極音速，亦即以超過5倍音速（5馬赫）以上的速度，飛向指定彈著點。

這是繼2017年10月，美國海軍及陸軍首次共同執行飛行實驗的一項測試，當時的原型飛彈就已證實能以極音速飛向指定目標。

美軍刻正規劃未來的測試，俾促使2020年代初期至中期，就能部署極音速作戰能力。
