在現代戰爭中，無人機與人工智慧早已成為主角。高速、大量且低成本的自殺型無人機正逐步改寫戰爭規則，迫使傳統防空系統面臨前所未有的挑戰。

In modern conflicts, traditional missile-based defense systems are struggling to keep up with swarms of small, agile drones. The emergence of AI-powered drone warfare has shifted the dynamics of the battlefield.

美國通用原子公司（General Atomics）日前在馬里蘭州的「2025年海空空間展」中，首度發表了一款可搭載於MQ-9B「死神」無人機上的高功率激光武器，強調這將是擊落低成本無人機群的關鍵技術。

At the 2025 Sea-Air-Space expo in Maryland, General Atomics unveiled a powerful laser weapon designed for the MQ-9B Reaper drone. This system marks a new era in drone-based aerial defense.

據了解，該激光裝置目前可輸出高達25千瓦能量，未來還將推進至300千瓦等級。這樣的能量輸出不僅能摧毀無人機，甚至有能力融化導彈外殼或破壞地面基礎設施。

Currently rated at 25kW, the laser has the potential to scale up to 300kW. At such levels, it can burn through missile casings or disrupt critical ground infrastructure.

從俄烏戰爭以來，自殺型無人機已成為常態戰術。根據國際安全研究機構統計，自2024年8月至2025年3月，俄軍已釋出逾1.5萬架伊朗製「沙赫德」無人機攻擊烏克蘭城市與基礎設施，形成巨大破壞與心理壓力。

Between August 2024 and March 2025, over 15,000 Shahed drones were launched by Russia against Ukrainian civilian and infrastructure targets—highlighting the urgent need for effective countermeasures.

現行對抗無人機的技術手段包括訊號干擾、AI入侵、甚至傳統攔截導彈，但這些方式多有缺陷。干擾器範圍有限、AI破解需時、導彈成本又高。而激光武器則提供即時、低成本、可重複使用的解方。

Unlike jammers and expensive missiles, laser weapons offer a more sustainable, real-time response—capable of neutralizing threats without significant logistical overhead.

通用原子展示影片中，可見MQ-9B無人機在模擬場景下使用激光，精準擊落多架類似沙赫德的無人機群，畫面震撼。

During the demonstration, a simulation showed the MQ-9B successfully intercepting and neutralizing multiple drone targets mid-air with its onboard laser—an impressive technological leap.

不過，這項技術也非萬能。MQ-9B雖具備超過40小時的飛行續航力，但啟動激光裝置後的續航時間仍待驗證。高能輸出對無人機的電池系統將是挑戰。

While the drone itself has over 40 hours of flight time, the energy demands of the laser system could significantly reduce mission duration. Battery optimization will be key to operational success.

事實上，美國空軍早在2020年代初就啟動了SHiELD（自衛高能雷射演示器）計畫，然而該計畫已於2024年被終止，未能實現原型測試。

Previously, the U.S. Air Force had invested in the SHiELD laser defense program, which was canceled in 2024 due to technical and logistical hurdles.

儘管如此，這次搭載激光的MQ-9B成功示範，仍被軍事觀察家視為美國在高能雷射武器領域的一大突破，也可能為日後發展載人機或艦艇搭載雷射提供重要參考。

This breakthrough is seen as a major milestone, potentially paving the way for future integration of laser systems into manned aircraft and naval platforms.

美國空軍研究實驗室也表示，雖然挑戰仍多，但此計畫在技術成熟度與實戰部署上，皆已邁出關鍵一步。

Despite the hurdles, the U.S. Air Force Research Lab emphasized that this development represents substantial progress toward real-world laser weapon deployment.
