美軍公開最新型戰略轟炸機“B-21突襲者”(B-21
Raider)迄今最詳細照片,它具有隱形及無人駕駛功能,可以裝載核子與傳統武器,根據五角大廈去年估計,每架預期耗費近7億美元。
根據美國國防部“防衛顯示資訊分布服務”(DVIDS)資訊,最新2張照片攝於7月31日,但直至上周的9月12日才公布。第1張照片從前方的地麵高度拍攝,首次揭露飛機規模大小,另一張從90度方位角拍攝,看出前所未見的設計元素。
相片資訊欄寫道,最先進的B-21突襲者“將提供可生存的、遠程的、穿透性的打擊能力,遏止侵略並保護美國、盟友及夥伴”,預期成為美國空軍轟炸機部隊的骨幹。
福斯新聞報導,B-21突襲者預計今年底首度試飛,2027年投入服役,取代目前使用的B-1槍騎兵戰略轟炸機(B-1
Lancer)及B-2幽靈戰略轟炸機(B-2 Spirit),2040年之前完全取代舊型轟炸機。
它由航太及國防科技公司“諾斯洛普.格魯曼”(Northrop
Grumman)打造,曆經多年秘密研發後,終於在去年12月首度曝光,但當局仍持續謹慎保密,公開資訊非常少,此前公開照片僅從駕駛艙正前方、高於飛機的角度拍攝。
美國國防部長奧斯汀(Lloyd
Austin)當時表示,“這證明了美國在獨創及創新的長期優勢,也證明了國防部的長期承諾,也就是建立先進能力,強化美國在當代與未來遏止侵略的能力。”
