大家还记得 MGS4 里,老蛇有拿过一把 XM-25 先进空爆榴弹发射器吗? 根据上周四 Military.com 军事情报网站消息表示,美军特种部队将在今年夏季於阿富汗 战场上试验这项武器;目前尚未清楚将会有多少把 XM-25 投入战场上进行实测,官方仅表 示将会少量分发给获选的单位使用 (代号字首为 X 者即表示"eXperimental"试验性质的非制式量产武器,所以 XM-25 仍在 试验阶段) 在 MGS4 游戏里,我们可以透过 XM-25 的照准器里看到由 XM-25 上搭载的雷射测距仪所 测得与目标物之间的距离,再用方向键来上下调整我们希望 25mm 先进空爆榴弹在发射飞 行多远後的距离引爆;而现实中的 XM-25 就是可以作出这样的精确攻击 (根据不才上次在知识频道上所看到类似性质的空爆弹引爆原理是,这类榴弹之所以可以设 定在多远的距离引爆是利用侦测及感应地球磁场的地磁线,再辅以弹头本身微晶片被设定 好在多少圈的飞行转数後该被引爆;简言之就是透过地磁线感应及弹头飞行圈数可以测知 榴弹大概飞行多远的距离,那事先设好预计引爆距离的话,该弹头上的微晶片就会在到达 预计飞行距离所需的转数一到就引爆该枚先进空爆榴弹) 美国陆军表示 XM-25 的整个操作使用过程低於 5 秒钟,而且受过基本射击训练的士兵就 可以办得到,也让它成为比使用迫炮或呼叫炮兵射击有效射程之外的小型武器、躲在掩体 後的目标要来得更为迅速且节省经费 (XM-25 的正式名称为"反遮蔽目标战斗系统"), XM-25 拥有约 500 米的点目标射程, 及 700 米的区域目标射程范围 XM-25 约 12 磅重, 29 寸长,由 Heckler & Koch 制造,它还内建热影像仪,这表示它在 夜间也能派上用场 不过让 XM-25 "精确导引"的代价可不便宜,据 Military.com 的报导,每把 XM-25 的预测 成本约为两万五千美元(约新台币 78 万 6 千元);在美国陆军 2012 年计划开始生产制造 之前,预计将会在 2011 年继续投入 3400 万美金(NT$ 10 亿 6960 万元)的研发经费 又,美国陆军之前曾说过他们希望能采购超过 12500 套 XM-25 先进空爆榴弹发射系统 '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 文章下面还有提供给 XM-25 所使用的各式 25mm 弹头图片可看, 目前现有的弹药(Current Ammo)有下列两种： 黄色是高爆空爆弹头 蓝色是训练弹 右边未来研发中的(Future Development)四种： 由左至右分别为: 浅绿色的非致命型钝击弹 绿色的非致命型空爆弹 橘色的攻坚破门弹 红色的穿甲弹 有兴趣的板友亦可参考 Military.com 的原文报导:(含展示影片) Army to Test "Game Changing" Gun in Combat http://goo.gl/g4do *展示影片中,XM-25射出的空爆弹飞至躲在窗後的假士兵头上引爆,没有破坏到後面的墙壁 (假士兵被爆头的一瞬间图片………) http://www.wired.com/images_blogs/dangerroom/2010/05/army_guns_1a.jpg -- 文章代码(AID): #01_aPrIl (Gossiping) [ptt.cc] [问卦] 请问 LV-426 的由来? 推 CarterJBurke:请问有没有 LV-426 太空殖民地的八卦? 谢谢 m(_ _)m 04/01 00:00 → DwayneHicks:去开垦,搞到最後连命都没了,不得已只好派USCM去救援; 04/01 00:04 → DwayneHicks:所以 Acheron 惑星在ALIENS就被正式称之为 LV-426 啦 04/04 00:02 推 EllenRipley:………………………………………………………………… 04/26 04:26 --
