美國通用原子航空系統公司（GA-ASI）宣布，已完成由塞拉內華達公司（SNC）研製的電子支援措施系統（Electronic Support Measures, ESM）在MQ-1C「灰鷹」延程型（Gray Eagle Extended Range, ER）無人航空系統上的飛行測試。這項整合是美國陸軍推動「灰鷹」無人機現代化的一環，目標是運用長程感測能力，協助地面指揮官掌握敵方整合式防空系統（IADS）的活動，提升部隊執行任務的安全性與可靠性。

General Atomics Aeronautical Systems, Inc. (GA-ASI) announced that it has completed flight testing of an Electronic Support Measures (ESM) system developed by Sierra Nevada Corporation (SNC) on the MQ-1C Gray Eagle Extended Range (ER) uncrewed aircraft system. The integration is part of the U.S. Army’s efforts to modernize the Gray Eagle, using long-range sensing to help ground commanders detect hostile integrated air defense systems (IADS) and improve operational safety and mission assurance.

長程偵蒐延伸交戰範圍外　提升部隊任務保障

Long-Range Sensing Extends Detection Beyond Weapon Engagement Zones

透過整合ESM系統，灰鷹無人機可在敵方武器交戰區（Weapon Engagement Zone, WEZ）外執行偵蒐，探測並蒐集敵方防空系統相關訊號，協助部隊掌握威脅部署與活動情況。這項能力可讓指揮官更早取得戰場資訊，並為後續任務規劃與目標定位提供支援，降低美軍在責任區（Area of Responsibility, AOR）內執行任務時面臨的風險。

With the ESM system integrated, the Gray Eagle can conduct reconnaissance beyond hostile Weapon Engagement Zones (WEZs), detecting and collecting signals associated with enemy air defense systems. This capability can provide commanders with earlier insight into threat deployments and activity, supporting mission planning and target identification while reducing risks to U.S. forces operating within their areas of responsibility (AORs).

GA-ASI總裁David R. Alexander表示，新能力將進一步提升陸軍灰鷹無人機的作戰價值。結合遠距離偵測能力，以及灰鷹本身的航程與長時間滯空特性，可協助指揮官持續掌握敵方防空系統是否運作，強化戰場態勢感知。

GA-ASI President David R. Alexander said the new capability would further enhance the operational value of the Army’s Gray Eagle. By combining long-range detection with the aircraft’s range and endurance, the system can help commanders maintain awareness of when an adversary’s air defense network is active.

小型化ESM結合開放式架構　加速系統升級

Compact ESM and Open Architecture Enable Faster Upgrades

此次搭載的ESM系統由SNC研製，採用小型化設計，可執行訊號偵測與蒐集任務。配合灰鷹無人機的開放式系統架構，相關設備能以較低的時間與成本完成整合，讓平台更容易導入新型任務系統，並依威脅變化持續升級。

Developed by SNC, the ESM system features a compact design for signal detection and collection. Combined with the Gray Eagle’s open systems architecture, the system can be integrated with reduced time and cost, making it easier to introduce new mission capabilities and adapt the platform to evolving threats.

透過在威脅射程之外執行電子偵蒐，灰鷹可深入掌握戰場電磁環境，同時降低自身暴露於敵方防空火力的風險。此外，ESM系統也可支援有人／無人協同作戰（Crewed-Uncrewed Teaming），提升有人駕駛陸軍航空器的生存能力，拓展無人機在複合式作戰中的支援角色。

By conducting electronic surveillance from outside hostile threat ranges, the Gray Eagle can gather information from deeper within the battlespace while reducing its exposure to enemy air defenses. The ESM system can also support crewed-uncrewed teaming, helping improve the survivability of crewed Army aircraft and expanding the Gray Eagle’s role in complex operations.

延續多項能力升級　拓展灰鷹作戰運用

Further Capability Upgrades Expand Gray Eagle’s Operational Potential

GA-ASI指出，此次整合SNC電子支援系統，是灰鷹無人航空系統持續提升作戰能力的一部分。該平台先前已在美國歐洲司令部相關活動、Vanguard演習及「融合計畫第五階段」（Project Convergence Capstone 5, PC-C5）等演訓中展示多項能力進展。

GA-ASI said the integration of SNC’s ESM system builds on a series of previous capability improvements to the Gray Eagle UAS. The platform has demonstrated additional advancements during activities associated with U.S. European Command, the Vanguard exercises, and Project Convergence Capstone 5 (PC-C5).

隨著長程電子偵蒐與有人／無人協同能力持續發展，灰鷹無人機的任務定位將不再侷限於傳統情報、監視與偵察，也可進一步支援敵方防空威脅辨識、戰場資訊蒐集及有人航空兵力的作戰保障，提升美陸軍在高威脅環境中的任務彈性。

As long-range electronic surveillance and crewed-uncrewed teaming capabilities continue to develop, the Gray Eagle’s role could extend beyond traditional intelligence, surveillance and reconnaissance. It may also support enemy air defense threat detection, battlefield intelligence collection, and operational protection for crewed aviation assets, providing the U.S. Army with greater flexibility in high-threat environments.
