美国将在六月去进行一次高爆测试，U16B复合体在内华达州试验基地上去确定一枚庞大的常规炸弹将执行对抗加固的地下目标多么有效。

    代号名称“神圣列板”（Divine Strake），测试将不包括一种传统的炸弹，但是将会引爆一个的巨大反应堆（共计700吨）：硝酸铵和燃料油（ANFO）连同136公斤C4炸药- 塞姆汀塑胶炸药（Semtex）的美国同等物-被当做起爆药。如同国防威胁减少代理处（DTRA）管理的系列部分，爆炸将会是超过一半千吨或500吨的TNT，至今为止最大的常规爆炸。

    当在一个命令下军事打击对抗伊朗去停止德黑兰的核计划是存在激励的争论。坚固而且深埋的目标逐渐地用来隐藏和保护指挥控制设备和储存非常规武器。最近的卫星图像显示在伊朗的纳坦兹（Natanz）正在动手处理防护它16深地下铀浓缩设施掩埋在25米厚的泥土、水泥和混凝土之下。

    “神圣列板”（Divine Strake）模拟将会包括引爆炸药在隧道表面顶部好于对隧道进口。它将会在一个石灰石床中进行去模拟已知目标可能的地质情形。依照DTRA，它将会评估计算机编码能力去预知对爆炸的地面-陡震环境和关联的隧道响应。第二个关心弹体内埋的装料延伸的空中爆炸和当它在当地地形上方扩散时候的改变。

'Divine Strake' - testing for Iran?

The US will conduct a high-explosives test in June at the U16B complex on the Nevada Test Site to determine how effectively a massive conventional bomb would perform against fortified underground targets.

Codenamed 'Divine Strake', the test will not involve a conventional bomb as such, but will detonate a vast pile (amounting to 700 tonnes) of ammonium nitrate and fuel oil (ANFO) with 136 kg of C-4 explosive - the US equivalent of Semtex - as the initiator. As part of a series conducted by the Defense Threat Reduction Agency (DTRA), the explosion will be equivalent to more than half a kiloton or 500 tonnes of TNT, the largest conventional explosion to date.

The test comes at a time when military strikes against Iran in a bid to halt Tehran's nuclear programme are being hotly debated. Hardened and deeply buried targets are increasingly used to conceal and protect command-and-control facilities and storage of non-conventional weapons. Recent satellite imagery shows that Iran is defending its 16 m deep uranium enrichment facilities at Natanz from attack by burying them under 25 m of dirt, cement and concrete.

The Divine Strake simulation will involve detonating the explosives on top of the surface above the tunnel rather than against the tunnel entrances. It will be conducted in a limestone bed to simulate the likely geological situation of known targets. According to the DTRA, it will assess the capability of computer codes to predict the ground-shock environment and associated tunnel response to the detonation. Of secondary interest is the air blast produced by a buried charge and its modification as it propagates over the local terrain.
