Is Israel's Iron Dome missile defense system ironclad?_我的网站

A |     JERUSALEM -- Since Israel activated the Iron Dome in 2011, the cutting-edge rocket-defense system has intercepted thousands of rockets fired from the Gaza Strip.The system has given residents a sense of security, and Israelis can often be seen watching the projectiles flying through the skies and destroying their targets overhead.But the current war with Hamas might be its stiffest challenge yet.In just two weeks, Hamas has fired 7,000 rockets toward Israel, according to the Israeli military. That is more than any of the previous four wars fought between Israel and Hamas since the militant group seized power in Gaza in 2007. On Oct. 7 alone, the first day of fighting, Hamas launched at least 2,000 rockets, according to data from West Point. Lebanon's Hezbollah has also fired hundreds of rockets along Israel's northern front since the fighting began.Most of the rockets have been intercepted. But some have managed to get through, killing at least 11 people and hitting buildings as far away as Tel Aviv, according to Israeli officials.Here is a look at the accomplishments — and limitations — of the Iron Dome.The Iron Dome is a series of batteries that use radars to detect incoming short-range rockets and intercept them.Each battery has three or four launchers, 20 missiles, and a radar, according to Raytheon, the U.S. defense giant that co-produces the system with Israel's Rafael Defense Systems.Once the radar detects a rocket, the system determines whether the rocket is headed toward a populated area. If so, it launches a missile to intercept and destroy the rocket. If the system determines the rocket is headed to an open area or into the sea, it is allowed to land, thus conserving missiles. According to the military, all interceptions occur in Israeli airspace.The military declined to comment on how many Iron Dome batteries are currently deployed. But as of 2021, Israel had 10 batteries scattered around the country, each able to defend a territory of 60 square miles (155 square kilometers), according to Raytheon. It is roughly 90% effective, according to Rafael.But it can get overwhelmed if a mass barrage of rockets is fired, allowing some to slip through. While it has performed well so far, the risk could be raised if Hezbollah enters the war. Hezbollah has an estimated 150,000 rockets and missiles.Each missile costs an estimated $40,000 to $50,000, according to the Institute for National Security Studies, a Tel Aviv think tank.The U.S. has invested heavily in the system, helping with development costs and replenishing it during times of fighting.President Joe Biden has said he will ask Congress for $14.3 billion in military aid for Israel. The majority of that would help with air and missile defense systems, according to the White House.“We’re surging additional military assistance, including ammunition and interceptors to replenish Iron Dome,” Biden said.___Find more of AP’s coverage at https://apnews.com/hub/israel-hamas-war。    9月22日，市委副书记、市长王庆海会见中交一公局集团建筑有限公司东北区域总经理杨广生，双方就道路交通、基础设施等领域深化合作进行交流。         　　王庆海对杨广生的到来表示欢迎，并简要介绍了抚顺市经济社会发展情况。他说，当前抚顺市正深入贯彻落实习近平总书记关于东北、辽宁、抚顺振兴发展重要讲话和指示批示精神，笃定高质量发展，积极培育壮大新质生产力，奋力实施全面振兴新突破三年行动，以承办十五冬雪上赛事为契机，全力推进产业转型、城市转型和社会转型，坚定不移完成全年经济社会发展目标任务，坚决打好打赢攻坚之年攻坚之战。希望企业持续关注抚顺、支持抚顺，地企携手在道路交通、物流运输、城市建设、乡村振兴、生态环保等领域进一步深化交流合作，实现互利共赢。抚顺市将积极围绕构建现代化产业体系、加快城市更新进程策划包装项目，持续优化营商环境，为企业在抚投资兴业创造有利条件。         　　杨广生感谢抚顺市对中交一公局集团建筑有限公司的信任和支持，简要介绍了企业发展历程以及在辽宁布局情况。他表示，抚顺区位优势明显、产业基础雄厚、发展潜力巨大，企业将深度拓展在抚发展空间，进一步加大在道路交通、物流运输、城乡基础设施建设等领域的合作力度，尽快落实具体合作项目，积极推动双方合作取得务实成效，为抚顺实现全面振兴新突破作出积极贡献。         　　副市长王进参加会见。
