据知名国际防务网站"海军新闻"（Naval News）6月23日报道，美国导弹防御局（Missile Defense Agency，MDA）已经选定使用AIM-174B"快枪手"远程空空 导弹搭载新开发的"广域效应"战斗部，以作为"高超音速导弹防御"的关键载具。 （资料图）挂载4枚AIM-174B的美国海军F/A-18F"超级大黄蜂" 【文/观察者网 山猫】 具体而言，这项面向小企业的招标项目，主要目标是研制用于反高超的战斗部，而非运载工具，竞标企业需要开发一种能够适配多种运载平台的弹头，其中 空射能力尤为重要。MDA官员还表示，目前的兴趣集中在"成熟的集成设计"方面，这类方案需要在合同授予后立即展示满足高端导弹防御性能指标的能 力，同时"可扩展有效载荷"也是优先考虑的条件之一，具体取决于战斗部载具的尺寸和动力水平，因此AIM-174B被"特别选定"为有价值的空射载具。 相较于美军航空兵目前广泛使用的AIM-120（左），AIM-174B（右）巨大的尺寸赋予了其推力更大的发动机和更加充沛的能量，因此具备了相关反导潜力 报道称，作为舰/陆射"标准6"的直接衍生品，AIM-174"已经被证明"能够在飞行末段"对抗 ...

据一名美国官员透露，以色列"箭"式（Arrow）反导系统库存已濒临耗尽，若冲突未能尽快解决，该国 对抗伊朗远程弹道导弹的能力将面临严峻考验。 以色列航空工业公司（Israel Aerospace Industries）未回应置评请求，以国防军在声明中称："以军已做 好应对任何情况的准备，但遗憾的是，我们无法评论弹药相关事宜。" 伊朗伊斯兰革命卫队当地时间周三（6月18日）凌晨发声明称，在昨夜今晨的"真实承诺3"第11阶段行动 中，革命卫队使用了"法塔赫-1"高超音速导弹，"意味着以军传奇防御终结的开始，以及以色列混乱和 毁灭的开始"。 声明称，"法塔赫"导弹威力巨大、机动灵活，向以色列中部特拉维夫地区发出了强有力的信息。此次袭 击表明，"伊朗完全控制了以色列的领空，而那里的居民在伊朗导弹袭击面前完全无助"。 当地时间18日早间，伊朗北部德黑兰省瓦拉明县负责人向媒体透露，伊防空部队在该县的贾瓦达巴德地 区又击落了一架以色列F-35战斗机。该负责人没有透露击落的具体时间。以方对此暂无回应。此前伊朗 方面多次声称击落以色列战机，以色列方面均否认。 该官员称，美国数月前已知晓以方防御系统的产能问题，并持续通过陆、海、 ...

Core Viewpoint - NATO Secretary General Jens Stoltenberg emphasized the need for member countries to increase their air defense and missile defense capabilities by 400% in response to ongoing threats from Russia [1] Group 1 - NATO member countries are required to make a "huge leap" in collective defense capabilities to address the persistent threats posed by Russia [1] - Stoltenberg stated that even if the conflict in Ukraine ends, the danger will not disappear, highlighting the necessity for enhanced military strength and capabilities to fully implement defense plans [1] - The Secretary General pointed out that the situation in Ukraine has demonstrated how Russia can create terror from the air, leading to a commitment to strengthen air defense systems [1]

【文/观察者网 熊超然】突然之间，曾亲密无间的美国总统特朗普和亿万富翁马斯克"反目成仇"。特朗 普威胁要取消太空探索技术公司（SpaceX）的政府合同，马斯克也扬言要退役"龙飞船"。 据《华盛顿邮报》当地时间6月7日独家报道，美国国家航空航天局（NASA）和国防部的官员们已迅速 敦促SpaceX的竞争对手加快研发替代航天器和火箭。例如，政府官员已联系至少三家商业航天公司， 询问其火箭研发进度以及何时能为政府任务提供服务。 报道称，若SpaceX停飞其"龙飞船"，此举将使NASA无法把其宇航员送往国际空间站，虽然马斯克后来 收回了威胁，但这还是让NASA和五角大楼的官员们感到震惊，NASA将宇航员的生命托付给了 SpaceX，五角大楼则严重依赖SpaceX发射其最敏感的卫星。 美国航天和国家安全机构内部的担忧反应突显出，美国政府严重依赖SpaceX执行关键任务（包括机密 任务）的风险。SpaceX与政府签订了数十亿美元的合同，向国际空间站运送人员和货物，为五角大楼 发射卫星，并开发情报机构使用的卫星。更令人担忧的是，其竞争对手追赶进度缓慢，这使得SpaceX 的主导地位在很大程度上没有受到挑战，美国政府也没有多 ...

Group 1: Relationship Between Trump and Musk - The relationship between Trump and Musk remains strained, with Trump indicating he has no intention of contacting Musk and is considering canceling government contracts with him [1][3] - Trump has expressed that terminating Musk's government subsidies and contracts could save billions, highlighting the significant financial ties between Musk's companies and the U.S. government [3][5] - Musk's companies, particularly SpaceX and Starlink, have heavily relied on federal contracts and subsidies, with SpaceX reportedly receiving over $22 billion in undisclosed contracts since 2000 [1][3] Group 2: Impact on SpaceX and NASA - SpaceX has a dominant position in the satellite launch market, with its Falcon 9 rocket handling 84% of U.S. satellite launches last year, and Starlink satellites making up 65% of operational satellites in orbit [4][5] - The potential severance of ties between the U.S. government and Musk could lead to significant delays in military satellite launches and halt NASA's operations, as there are currently no reliable alternatives to SpaceX for missions to the International Space Station [5][6] - The loss of SpaceX could jeopardize strategic projects like the "Iron Dome" missile defense system, which may rely on contracts for missile detection satellites [5][6] Group 3: Political Dynamics and Financial Contributions - Musk has previously been a significant financial supporter of Trump, contributing $277 million through his PAC, but is now exploring the formation of a new political party, indicating a shift in his political strategy [7][8] - Recent polls show a decline in Musk's support compared to Trump, with only 8% of voters choosing Musk over Trump when forced to pick between the two [8] - There are growing concerns among Republican lawmakers regarding Musk's financial influence, as his contributions have not translated into significant electoral success for the candidates he supported [8][9]

围绕美国关税政策，日美部长级谈判即将举行第五轮会谈，特朗普政府"对等关税"的暂停期限也将于7 月9日结束，而率先与美国展开谈判的日本仍未得到任何承诺。日本首相石破茂计划利用出席七国集团 （G7）峰会和北约首脑会议的机会与特朗普会晤，力争通过最高层谈判来打开局面。不过，他自己也 表示，这"不是一件简单的事"。 5日上午，日本经济再生担当大臣赤泽亮正（左二）从东京羽田机场启程前往美国。 日本经济再生担当大臣赤泽亮正5日再次赴美，距离上一轮日美部长级谈判仅相隔5天。按照赤泽亮正的 说法，第四轮谈判中"双方了解了彼此立场，旨在达成协议的讨论取得进展"，双方一致同意继续磋商。 话虽如此，可日方"要求美国调整关税"的目标仍看不到希望。 不仅如此，就在赤泽亮正在美谈判期间，特朗普5月30宣布将钢铝关税提高到50%。对此，赤泽亮正表 示，在与美国财政部长贝森特等人进行第四轮谈判时，美方并未提及此事，而日方谈判的主要目标就是 要求美方全面撤销包括汽车及零部件、钢铁和铝制品在内的关税。据测算，如果维持对汽车加征25%的 关税，日企每小时将损失1亿日元（约合69.9万美元），这无疑将重创日本经济。 齐鲁晚报·齐鲁壹点记者 赵世峰 ...

Core Viewpoint - The deteriorating relationship between Trump and Musk poses significant risks to NASA and the Pentagon, as they heavily rely on SpaceX for various space and defense projects [1][2][7] Group 1: SpaceX's Role and Contracts - SpaceX has received over $22 billion in non-classified contracts from the U.S. Department of Defense and NASA since 2000 [1] - Currently, SpaceX is the only U.S. spacecraft capable of transporting astronauts and supplies to the International Space Station (ISS) [2] - NASA has awarded SpaceX contracts totaling over $15 billion, making it a core supplier for the agency [1][2] Group 2: Impact of Trump-Musk Conflict - Trump's threat to terminate all government contracts with Musk's companies could severely impact NASA's operations, particularly its ability to send astronauts to the ISS [2][6] - The conflict may lead to significant adjustments in U.S. space policy and budget allocations, potentially favoring other contractors like Boeing, which has faced delays and budget overruns [5][6] - Analysts suggest that if Trump prioritizes political retaliation, it could delay the development of U.S. space programs and affect military space capabilities [6][7] Group 3: Future Implications - The White House's proposed budget initially aimed to cut funding for costly projects like the Space Launch System (SLS) and Orion spacecraft, which would benefit SpaceX and other commercial space companies [6] - However, due to the conflict, a modified proposal may restore funding for these projects, particularly benefiting Boeing [6] - Experts warn that terminating contracts with SpaceX could lead to a significant loss of capabilities for the Pentagon and NASA, as no other company currently matches SpaceX's capabilities [7]
