利劍」無人作戰飛機（英語：Sharp Sword）簡稱「利劍」無人機或「利劍」，是中華人民共和國瀋陽飛機設計研究所設計、洪都航空工業集團生產的飛翼布局大型隱形無人攻擊驗證機。「利劍」採用了隱身低流損蛇形進氣道，該先進低隱身反射進氣道於2013年5月在車台進行了歷時一個多月的與發動機匹配的試車摸底試驗。^[2]首架「利劍」無人作戰飛機於2012年12月13日下線，^]隨後開始進行地面測試。2013年11月21日13時許，「利劍」無人作戰攻擊機在西南某試飛中心成功完成首飛。這也標誌著中國成為第四個成功完成專用無人作戰飛機首飛的國家。^]

外界分析認為，「利劍」無人作戰飛機目前使用的是俄羅斯克里莫夫設計局的RD-93渦扇發動機。也有人指出，該種飛機可能會被裝備在遼寧號航空母艦上。

Sharp Sword (Li-Jian or Lijian, 利剑), jointly developed by SYADI, SAU and Hongdu Aviation Industry Group (HAIG), is one of the two models of the AVIC 601-S progressed further than proof of concept design by evolving into larger size (the other being Dark Sword). The Sharp Sword is jet-powered and has a wingspan of 14 meters. It’s not yet known the precise mission Sharp Sword is assigned, but possible missions would including reconnaissance and eventually combat missions.
