高超音速导弹竞争，谁家能赢？

Background info.
    1. 高超音速导弹(hypersonic missiles)竞争是军事大国竞争的焦点.
    2. 中国和俄国可能、似乎、大概、也许遥遥领先.
        美国落后. The United States does not have any fielded hypersonic missiles at this moment.
    3. 美国正在积极发展拦截高超音速导弹的解决方案.
    4. Rocket Lab的火箭能用作拦截试验的靶子(这点是我夹带的私货)

Rocket Lab made a press release on Wednesday January 8.
