一、2022年3月19日,在「俄烏戰爭」爆發近一個月後,俄羅斯國防部正式公布,俄軍運用「匕首」高超音速導彈摧毀烏克蘭西部的大型地下彈藥庫,這是此款高速度、抗干擾能力強的導彈首次實戰表現,其展現的能力也迅速在戰場上占有一席之地。二、當前俄、「中」兩國都已在「高超音速導彈」發展上展現成果,美國亦加速研發試射腳步;尤其中共已完成此類導彈的軍事部署,搭配其「反介入/區域拒止」戰略,未來印太地區的平衡均勢及我國防衛作戰,恐將面臨更大威脅。三、由於「高超音速導彈」載臺型式多元,加上飛行速度遠高於巡弋飛彈或超音速飛彈;加上終端攻擊時能高速變換飛行軌跡,使其擁有彈道飛彈的高航速和長射程,亦兼具巡弋飛彈的中、低空機動能力,確實讓防守方「防不勝防」。此型導彈的問世,已對目前各國的飛彈防禦系統造成極大的挑戰,也凸顯防守方的脆弱性。面對兩岸對峙形勢日趨嚴峻,我國如何因應,確實值得深入探討。
1.On March 19, 2022, nearly a month after the outbreak of the "Russia-Ukraine War", the Russian Ministry of Defense officially announced that it had used the "Kinzhal" hypersonic missile to destroy a large underground ammunition depot in western Ukraine. This marked the first combat performance of this high-speed, highly resilient missile, establishing its place on future battlefields. 2.Observing the current major military powers such as the United States, Russia, and China, it is evident that they have all made significant advancements in hypersonic missile development. In particular, China has completed military deployment of this type of missile, which, combined with its "Anti-Access/Area Denial" strategy, poses a greater threat to future balance in the Indo-Pacific region and to our national defense operations. 3.Due to the diverse launch platforms for hypersonic missiles and their speeds significantly exceeding those of cruise or supersonic missiles, as well as their ability to rapidly change flight trajectories during terminal attack, they possess the high speed and long range of ballistic missiles while also maintaining the mid- to low-altitude maneuverability of cruise missiles. This makes them indeed "hard to defend against". The emergence of such missiles presents significant challenges to the missile defense systems of various countries, highlighting the vulnerabilities of defensive forces.
