" Some American technical experts also say they want hard evidence before judging whether Iron Dome knocked out as many rockets as Israel has claimed. Iron Dome’s most salient feature, according to American experts now examining after-action reports from Gaza, may well be its software...
But some antimissile experts have expressed doubt about Israeli claims for Iron Dome, which is built by Israeli defense firms but has received about $275 million in financial support from the United States. Bright flashes can create a visual impression of overwhelming interceptor success, when in fact they may represent nothing more than the interceptor warhead blowing up, these skeptics warn.
“I’ve met the guys in Israel, and they’re smart,” said Richard M. Lloyd, an antimissile expert with more than a dozen patents and two major textbooks on warhead design to his credit. “But I’m not seeing the things I want to see” to prove that Iron Dome actually succeeded to the extent described by Israel.
Mr. Lloyd, who works for Tesla Laboratories Inc., a defense contractor in Arlington, Va., said he had studied dozens of publicly available photographs of spent rockets that landed on Israel. Few of them, he said, showed signs of damage from Iron Dome’s exploding warhead and the specific mechanism by which the interceptor is designed to make its kill — a dense spray of speeding metal fragments.". But notice that the headline of this piece only implies success.
