洛克希德的一种爆炸威力可调的导弹

Aerojet has conducted a successful demonstration of its "scalable effects" warhead. The flight test wascarried out on November 30, 2011, at the White Sands Missile Range in New Mexico using Lockheed Martin's new Guided Multiple Launch Rocket System-Plus (GMLRS+). As the name suggests, the scalable effects warhead allows the user to select the explosive yield of the weapon depending on the nature of its intended target.The November 2011 flight test saw the GMLRS+ rocket score a direct hit on a target 30 miles (49 km) away. However, a GMLRS+ rocket featuring Aerojet's improved production motor was previously demonstrated in August 2011 over a range of 74 miles (119 km) - an improvement of some 31 miles (50 km) over the current GMLRS round."The 'scalable effects' warhead was set to low-yield prior to the flight and scored a direct hit on the target," said Scott Arnold, vice president of precision fires in Lockheed Martin's Missiles and FireControl business. "The performance of both the GMLRS+ rocket and the scalable effects warhead were outstanding, validating our continued investmentin evolving the proven GMLRS weapon system to address current and future threats."The tests, supported by the U.S. Army's Precision Fires Program Office, were internally funded byLockheed MartinandAerojet.A "scalable effects" warhead?The ability to vary to explosive power of a warhead has clear implications for reducing risk to friendly forces, civilians and also reducing unnecessary damage to infrastructure other than the intended target.Historically, the notion of varying the explosive power of a warhead has been primarily linked with nuclear weapons, where the term"dial-a-yield" is generally used. In this case, the amount of material which can "boost" the yield (for example, tritium) can be varied, as can the performance of "initiators," which allow a chain reaction to propagate.Achieving this with conventional (i.e. chemical) explosives presents different challenges. A plausible explanation of how this may be achieved would be varying the manner in which the explosive material contained in the warhead is detonated. However, Aerojet isn't giving away any secrets on how its scalable effects warhead is able to vary its yield.

现代战争已经在精确打击的道路上越走越远了，像当年喀秋莎火箭弹覆盖式轰炸那样的粗放式武器想必也将逐渐退出舞台了吧？美国喷气飞机公司近期试射了他们的一种新型导弹并获得成功。这种导弹可以用洛克希德·马丁公司的增强型联装导弹发射系统发射，它的爆炸威力还可以进行调整，以适应不用的作战要求。比如调整爆炸威力精确打击恐怖分子的据点，全灭恐怖分子而不伤及隔壁住的平民。它的具体构造是机密不能透露，但喷气飞机公司还是模糊地透露这爆炸威力的改变，是通过对固定量装药的形状和位置进行调整而实现的。
