2025年7月13日，全球最大規模的美澳定期聯合軍演——護身軍刀（Talisman Sabre 2025），在澳洲昆士蘭、北領地及聖誕島啟動。本屆演習創下35,000至40,000名兵力、19國參演、首次納入巴布亞紐幾內亞海域的大規模規模，比以往更遠、更深、更跨域 。

此次軍演首次納入AI智慧指揮系統（BigBear.ai ConductorOS）與網路戰、防禦太空信息作戰，並在訓練中穿插美澳共同使用HIMARS多管火箭、Typhon防空導彈、太空監控與零信任網防系統等先進兵器與網戰能力 。衛生後勤與醫療救援、海空實彈演練、陸海空與多域聯合作戰也同步啟動 。

本屆演習也首次伴隨空天與太空域整合演練，展現聯軍跨域作戰新常態；且國防高層在典禮中明示：此次行動為「遏阻而非好戰」，目標是彰顯盟友整合能力與區域維穩決心。

演習期間，中國偵察船已派遣艦隻靠近觀察，澳方則回應將調整指揮方式，以因應可能的情報洩露。值得注意的是，演習同步進行澳洲總理訪中，凸顯澳在盟友協防與經濟外交間的微妙平衡。

🔍 三大觀察重點

1. AI、網戰與太空作戰首度納入聯演
    
   • BigBear.ai ConductorOS 平台與零信任防禦系統首次投入聯演，標誌多域數位戰時代來臨。
      
2. 實彈火力與跨域作戰能力再升級
    
   • HIMARS、Typhon系統聯合火力部署，演練範圍涵蓋海、空、地面與太空，顯示印太聯防高度整合。
      

3. 台海安全再升溫，盟友政治立場浮現
    

   • U.S.讓澳盟緊盯台海，中共偵察現場緊張蔓延。對台灣而言，更強韌的盟聯象徵重要戰略保險。

    

📰 U.S.-Australia “Talisman Sabre 2025” Joint Military Drill Launches with Record Scale, Integrates AI and Space Warfare — Eyes on Taiwan Strait Tensions

On July 13, 2025, the Talisman Sabre 2025—the largest recurring U.S.-Australia joint military exercise—kicked off across Queensland, the Northern Territory, and Christmas Island. This year’s drill involves 35,000 to 40,000 troops from 19 nations, and for the first time, extends into the waters of Papua New Guinea, marking a broader and deeper multi-domain scope than ever before.

For the first time, the exercise incorporates AI-based command systems such as BigBear.ai’s ConductorOS, alongside cyber warfare, space-based information operations, and advanced platforms including HIMARS multiple rocket launchers, Typhon air defense systems, space surveillance, and zero-trust cybersecurity systems. Training scenarios also cover joint live-fire missions, medical evacuation drills, and full-spectrum air-land-sea-space coordination.

This iteration also debuts air-space integration operations, representing a shift toward multi-domain warfare. Defense officials emphasized during the launch that the aim is “deterrence, not provocation,” signaling the allies’ resolve for regional security and interoperability.

During the exercise, Chinese surveillance vessels were spotted nearby, prompting Australian military leaders to adjust command protocols to mitigate potential intelligence leaks. Notably, the exercise coincides with the Australian Prime Minister’s state visit to China, highlighting Canberra’s balancing act between defense alliances and economic diplomacy.

🔍 Three Key Takeaways

1. AI, Cyber, and Space Warfare Enter Multinational Exercises
    
   • The deployment of BigBear.ai’s ConductorOS and zero-trust defense systems marks a leap toward multi-domain digital warfare.
2. Live-Fire and Multi-Theater Coordination Expand Capabilities
    
   • Integration of HIMARS and Typhon systems across land, sea, air, and space illustrates heightened Indo-Pacific joint defense cohesion.

3. Taiwan Strait Security Comes into Focus
    

   • The presence of Chinese reconnaissance signals growing cross-strait tension. For Taiwan, stronger allied coordination signals a critical layer of strategic insurance.
