美國通用原子公司(General Atomics)展示新型超大型無人潛航器Ranger,艇長最長達41.15公尺,未來可攜帶其他無人潛航器及感測設備,目標是在水下連續執行數年任務,可望替美國海軍有人潛艦分擔海底監視勤務。

軍事媒體《Army Recognition》報導,通用原子電磁系統公司(GA-EMS)11月3日公開影片,展示Ranger及較小型的GA-Ray(GRay)2款無人水下載具。兩者採用浮力驅動滑翔推進,透過反覆下潛與上浮,藉由水動力產生前進推力,以降低長時間航行對螺旋槳推進的依賴。

根據GA-EMS公布的資料,GRay長約6.71公尺,預定執行數週至數個月任務;Ranger則規劃長達30.48至41.15公尺,採模組化設計,可依任務需求更換酬載,包括海底感測設備,以及外部尺寸約6.1公尺長的標準貨櫃級任務模組。

Ranger同時採用母載具搭配子載具的構想,可先將大型或較小型的無人潛航器運送至指定海域,再釋放執行獨立任務。GA-EMS公開的影片還展示子載具透過發射管釋放四軸無人機,讓水下平台有機會延伸執行空中偵察;不過,相關空中無人機的具體性能及實際任務配置尚未公開。

不過,這項構想距離多年部署仍有工程挑戰。《Naval News》11月9日報導,GA-EMS海事計畫副總裁齊辛(Rolf Ziesing)表示,目前母載具與子載具的水下測試時間最長已達70天。相較之下,Ranger設定的多年部署目標,還必須克服長期能源供應、機械可靠性及感測設備持續運作等問題。

由於水下無法直接使用衛星定位,Ranger與GRay規劃結合慣性導航系統及都卜勒計程儀輔助定位,也將水下通訊及新型感測技術納入發展方向,相關系統的實際性能仍有待驗證。

GA-EMS希望Ranger未來能長時間駐守指定海域,執行水下監視、感測及無人載具部署等任務,減少高價值有人潛艦的勤務負荷。目前尚無公開資料顯示Ranger已獲美國海軍正式採購或服役。

Israel launches 1,000-pound cruise missile! The warhead has been increased to 4 times that of the previous generation, specifically targeting these three types of high-value targets.

Israel's Rafael Advanced Defense Systems has launched a new type of "Super Ice" long-range cruise missile, equipped with a 454-kilogram warhead, equipped with artificial intelligence, anti-jamming and low-altitude precision guidance capabilities, and can be launched from air, land and sea platforms.

The Brave Eagle high-education aircraft malfunctioned and overran the runway. Air Force: This was the only "serious mechanical failure" among the nine cases in the past three years.

On the 10th, a Brave Eagle advanced trainer aircraft from the Air Force Flight Training Department overshot the runway due to abnormal braking and a tire puncture. Fortunately, the crew was safe. Air Force Chief of Staff Li Qingran said today that there have been nine braking-related incidents of this type of aircraft in the past three years, and this is the most serious mechanical failure accident. The entire fleet has been grounded for inspection.

Japan self-developed 3 military unmanned combat vehicles, the largest 10-ton tracked vehicle exposed

The Japan Defense Equipment Agency displayed the research and development results of three military unmanned ground vehicles, weighing less than 1 ton, 1 to 2 tons and 5 to 10 tons respectively. The largest model adopts a low crawler body and may be equipped with heavy sensors, supplies and even weapons in the future. This shows that Japan is shifting from relying on foreign systems to independently developing special military unmanned vehicles.
