大家還記得 MGS4 裡,老蛇有拿過一把 XM-25 先進空爆榴彈發射器嗎? 根據上週四 Military.com 軍事情報網站消息表示,美軍特種部隊將在今年夏季於阿富汗 戰場上試驗這項武器;目前尚未清楚將會有多少把 XM-25 投入戰場上進行實測,官方僅表 示將會少量分發給獲選的單位使用 (代號字首為 X 者即表示"eXperimental"試驗性質的非制式量產武器,所以 XM-25 仍在 試驗階段) 在 MGS4 遊戲裡,我們可以透過 XM-25 的照準器裡看到由 XM-25 上搭載的雷射測距儀所 測得與目標物之間的距離,再用方向鍵來上下調整我們希望 25mm 先進空爆榴彈在發射飛 行多遠後的距離引爆;而現實中的 XM-25 就是可以作出這樣的精確攻擊 (根據不才上次在知識頻道上所看到類似性質的空爆彈引爆原理是,這類榴彈之所以可以設 定在多遠的距離引爆是利用偵測及感應地球磁場的地磁線,再輔以彈頭本身微晶片被設定 好在多少圈的飛行轉數後該被引爆;簡言之就是透過地磁線感應及彈頭飛行圈數可以測知 榴彈大概飛行多遠的距離,那事先設好預計引爆距離的話,該彈頭上的微晶片就會在到達 預計飛行距離所需的轉數一到就引爆該枚先進空爆榴彈) 美國陸軍表示 XM-25 的整個操作使用過程低於 5 秒鐘,而且受過基本射擊訓練的士兵就 可以辦得到,也讓它成為比使用迫炮或呼叫炮兵射擊有效射程之外的小型武器、躲在掩體 後的目標要來得更為迅速且節省經費 (XM-25 的正式名稱為"反遮蔽目標戰鬥系統"), XM-25 擁有約 500 米的點目標射程, 及 700 米的區域目標射程範圍 XM-25 約 12 磅重, 29 吋長,由 Heckler & Koch 製造,它還內建熱影像儀,這表示它在 夜間也能派上用場 不過讓 XM-25 "精確導引"的代價可不便宜,據 Military.com 的報導,每把 XM-25 的預測 成本約為兩萬五千美元(約新臺幣 78 萬 6 千元);在美國陸軍 2012 年計劃開始生產製造 之前,預計將會在 2011 年繼續投入 3400 萬美金(NT$ 10 億 6960 萬元)的研發經費 又,美國陸軍之前曾說過他們希望能採購超過 12500 套 XM-25 先進空爆榴彈發射系統 'Smart' grenade launcher heads to Afghanistan： http://news.cnet.com/8301-13639_3-20004488-42.html The futuristic-looking XM-25 shoulder-fired weapon, a sort of a souped-up grenade launcher, will soon be getting its trial by combat. U.S. Special Forces soldiers will be trying out the XM-25 in Afghanistan this summer, according to a report Thursday at Military.com. It's not clear how many of those weapons will be going, but the numbers are likely to be quite small, given that it's still early days for the specialized system. The XM-25, which fires a 25mm airbursting, high-explosive round, packs a whole lot of smarts to go with its punch. With the click of a button, a laser rangefinder quickly determines how far away the target is, and that distance gets displayed in the weapons optics, along with crosshairs already adjusted for factors such as temperature and air pressure. The built-in target acquisition/fire control capabilities also program the relevant data into the sensor- and microchip-equipped ammo. (Wired's Danger Room blog has a photo of an XM-25 round hitting a target.) The Army says that the whole process takes less than five seconds and can be done by a soldier with just basic marksmanship skills, making it quicker and cheaper to use than mortar or artillery for targets outside the effective range of small arms, or behind cover. (Its formal title is the XM-25 Counter Defilade Target Engagement System.) The XM-25 has a point target range of about 500 meters and an area target range of 700 meters. The 12-pound, 29-inch-long weapon, made by Heckler & Koch, also has a built-in thermal sight, meaning it's effective at nighttime, too. Smart doesn't come cheap, of course. Military.com reports that cost projections for the XM-25 come to about $25,000 per weapon and that the Army expects to spend $34 million to continue development in 2011, ahead of planned production starting in 2012. The Army has said it hopes to purchase more than 12,500 XM-25 systems. cnet 文章下面還有提供給 XM-25 所使用的各式 25mm 彈頭圖片可看, 目前現有的彈藥(Current Ammo)有下列兩種： 黃色是高爆空爆彈頭 藍色是訓練彈 右邊未來研發中的(Future Development)四種： 由左至右分別為: 淺綠色的非致命型鈍擊彈 綠色的非致命型空爆彈 橘色的攻堅破門彈 紅色的穿甲彈 有興趣的板友亦可參考 Military.com 的原文報導:(含展示影片) Army to Test "Game Changing" Gun in Combat http://goo.gl/g4do *展示影片中,XM-25射出的空爆彈飛至躲在窗後的假士兵頭上引爆,沒有破壞到後面的牆壁 (假士兵被爆頭的一瞬間圖片………) http://www.wired.com/images_blogs/dangerroom/2010/05/army_guns_1a.jpg -- 文章代碼(AID): #01_aPrIl (Gossiping) [ptt.cc] [問卦] 請問 LV-426 的由來? 推 CarterJBurke:請問有沒有 LV-426 太空殖民地的八卦? 謝謝 m(_ _)m 04/01 00:00 → DwayneHicks:去開墾,搞到最後連命都沒了,不得已只好派USCM去救援; 04/01 00:04 → DwayneHicks:所以 Acheron 惑星在ALIENS就被正式稱之為 LV-426 啦 04/04 00:02 推 EllenRipley:………………………………………………………………… 04/26 04:26 --
