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

A |     【环球网科技综合报道】7月22日消息，据macworld报道称，在苹果最新推送的iOS 27开发者预览版Beta 4代码中，首次出现了针对“多电池”iPhone的底层适配逻辑。这一系统级的重大变动，被业界视为苹果首款折叠屏手机“iPhone Ultra”即将发布的明确信号。    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。         在此次更新的电池健康功能模块中，开发者发现了多处此前从未出现过的字符串。与目前所有在售iPhone仅使用单数形式“battery”不同，新代码中明确使用了复数形式的“batteries”。例如，系统提示文本变更为“这部iPhone中的电池性能表现正常”以及“这部iPhone中的电池健康度已显著下降”。

B | 更关键的是，代码中还新增了“其中一块电池并非苹果原装部件”的独立验证逻辑。

C |          外媒称，这表明，苹果正在系统层面为支持两块独立电芯的设备进行底层适配。         此前供应链消息也透露，苹果首款折叠屏iPhone Ultra将采用分体式双电芯方案，两块电芯容量分别为1921mAh和2962mAh，总容量达到4883mAh。iOS 27代码中关于“独立检测单块电池”的描述，进一步暗示该机型可能支持独立维修——若其中一块电芯出现衰减，用户无需更换整套电池组件，从而有望降低折叠屏设备的后期维护成本。         目前，多方供应链消息确认，iPhone Ultra已进入大规模量产阶段，预计将作为苹果首款折叠屏旗舰，在今年9月的秋季发布会上与iPhone 18 Pro系列同台亮相。（青云）。
