"  It&amp;#039;s the ultimate national-security nightmare scenario: Enemy intelligence agents get a detailed, behind-the-curtain view of the interceptors meant to stop a ballistic missile attack on the United States. That&amp;#039;s the specter raised by the hush-hush raid Monday morning on the home of a scientist who worked on marquee missile defense programs while employed by defense contractor Raytheon. FBI and Department of Homeland Security agents seized boxes from the Boston-area home of Richard Lloyd, whose title was &amp;quot;manager of the Warhead Lethality Group of the Raytheon Company Electronic Systems Division,&amp;quot; according to an online bio for his 1998 book Conventional Warhead Systems Physics and Engineering Design.  Lloyd has not been charged, and a spokesperson for the U.S. Attorney&amp;#039;s office in Boston has said &amp;quot;there&amp;#039;s no immediate threat to the public.&amp;quot; Lloyd&amp;#039;s specialty is rare: developing missiles that target other missiles. Since ballistic missiles are a cornerstone weapon adopted by nations that are potential foes (Iran, North Korea or China, for example), any insight on the limitations of U.S. and allied missile-defense systems could present a serious threat. Lloyd&amp;#039;s book references his expertise in two modern missile defense cornerstones: the PAC-3, a Patriot missile interceptor variant, and the Medium Extended Air Defense System, which is still in development. This has to send chills down the spines of mission planners in Taiwan, Washington and Saudi Arabia. &amp;quot;Direct hit, warhead design, and fragmentation are comprehensively discussed for the first time in print,&amp;quot; says the text on the jacket of Lloyd&amp;#039;s book, which &amp;quot;features a previously unpublished investigation of energy, momentum, and methods for estimating damage on very complex ballistic missile payloads, such as submunitions of chemical and biological nature.&amp;quot; The FBI and Raytheon have been tight-lipped about the searches; Raytheon has said only that Lloyd is a former employee. Although he has not been accused of any wrongdoing, it&amp;#039;s worrisome, to say the least, that a researcher of his caliber is under investigation. "^^<http://www.w3.org/2001/XMLSchema#string>
