美國國防部近日宣布，與通用原子航空系統公司（GA-ASI）簽署高達9,920萬美元的研發合約，啟動代號「幽靈」（Ghost）的無人機專案。該計畫將結合油電混合動力與匿蹤科技，打造具備未來戰場優勢的新型無人飛行平台。

The U.S. Department of Defense has signed a $99.2 million contract with General Atomics Aeronautical Systems, Inc. (GA-ASI) to develop the “Ghost” UAV—a next-generation intelligence, surveillance, and strike platform that will combine hybrid propulsion with advanced stealth features.

根據報導，「幽靈」計畫由美國空軍研究實驗室（AFRL）主導，研發方向聚焦於油電混合推進系統與導風扇設計。這類設計將有助於延長航程、提升能源效率，並降低熱源與聲學訊號，以提升突穿敵方防空網的能力。

Led by the Air Force Research Laboratory, the Ghost project centers on hybrid power and ducted fan propulsion to enhance endurance and operational range while reducing infrared and acoustic signatures—key attributes for penetrating advanced air defense systems.

此外，該機將採用具匿蹤特性的外型設計，能攜帶精確打擊武器，遂行高風險監控與攻擊任務。這款無人機預計在2028年前完成原型設計，未來有望取代MQ-9「死神」成為美軍主力無人機。

Designed with low observability in mind, the Ghost UAV will feature a stealthy shape and precision strike capability. The prototype is scheduled for completion by June 2028, potentially replacing the MQ-9 Reaper as the U.S. military's mainstay UAV for intelligence and combat operations.

通用原子表示，「幽靈」無人機的技術基礎，部分來自早前公開的「開局」（Gambit）模組化平台，並與現行「協同戰鬥航空器」（CCA）計畫中開發的YFQ-42A原型機共享研發經驗。

According to GA-ASI, Ghost draws upon technologies developed for its previous “Gambit” modular UAV concept and shares engineering lineage with the company’s YFQ-42A prototype for the Collaborative Combat Aircraft (CCA) initiative.

此計畫不僅展現美軍對次世代無人作戰平台的高度期待，也強化其「彈性作戰部署」（Agile Combat Employment, ACE）及「分散式作戰」（Distributed Maritime Operations, DMO）能力，確保未來戰場上的持續優勢。

The initiative reflects the U.S. military’s strategic push toward Agile Combat Employment (ACE) and Distributed Maritime Operations (DMO), solidifying its edge in next-generation warfare.
