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。活跃区共59个，其中19个为黑区，包括裕廊西1道和42街。
