美国在危机期间指挥其核力量的能力正在大规模军事演习中接受检验。
America’s ability to command its nuclear forces during a crisis is being put to the test in sweeping military drills.
周二的一份声明证实，美国战略司令部的年度“全球雷霆27”演习正在进行中，官员们警告说，美国人可能会看到更多轰炸机和支援飞机从头顶飞过。该行动模拟复杂场景，以检验军事决策、通信和报复能力。
A Tuesday statement confirmed that US Strategic Command’s annual Global Thunder 27 exercise is underway, with officials warning Americans could see more bombers and support aircraft flying overhead. The operation simulates complex scenarios to test military decision-making, communications, and retaliation capabilities.
演习旨在保持美国核力量处于准备就绪、安全可靠的状态，确保其能够有效运作并威慑攻击。
The drills aim to keep America’s nuclear forces ready, safe and secure, ensuring they can operate effectively and deter an attack.
飞行数据显示，过去几小时内，B-52轰炸机从北达科他州迈诺特空军基地起飞，多架E-6B“水星”飞机在美国上空活动。
Flight data tracked B-52 bombers departing Minot Air Force Base in North Dakota and multiple E-6B Mercury aircraft operating over the US in the past few hours.
E-6B被称为“末日飞机”，充当飞行指挥与通信中心，使国家领导人能够与美国的核力量保持联络。
Known as ‘doomsday planes,’ the E-6Bs serve as flying command and communications centers, keeping national leaders connected to America’s nuclear forces.
航空通告显示，大西洋、太平洋部分区域以及佛罗里达州上空设立了临时空域保留区，可能与“全球雷霆”演习有关，其中一份通告明确提到了这场核演习。
Aviation notices outlined temporary airspace reservations over parts of the Atlantic, Pacific and Florida potentially linked to Global Thunder, with one explicitly naming the nuclear exercise.
官员们强调，“全球雷霆”是年度演习，并非针对任何国家或当前世界事件的回应。
Officials stressed that Global Thunder is an annual exercise and is not a response to any country or current world events.
美军启动了一项核战备演习，旨在保持美国核力量处于准备就绪、安全可靠的状态，确保其能够有效运作并威慑攻击（资料图）。“全球雷霆27”于10月22日开始，预计持续约10天。
The US military has launched a nuclear readiness drill aimed at keeping America’s nuclear forces ready, safe and secure, ensuring they can operate effectively and deter an attack (stock) Global Thunder 27 started on October 22 and is expected to last roughly 10 days.
尽管演习已进行数日，但有关军机在美国上空飞行的报道直到过去一天才出现。
Although the drills have been underway for days, reports of military aircraft flying over America have only surfaced in the past day.
周二下午至少看到五架末日飞机，据报道当天上午还有一架从俄克拉何马州起飞，正向西北方向飞行。
At least five doomsday planes were seen Tuesday afternoon, with another reported this morning that left Oklahoma and is moving northwest.
飞行追踪数据还显示，B-52轰炸机从北达科他州迈诺特地区向北飞入加拿大，另有其他轰炸机在路易斯安那州和密西西比州上空沿环形航线飞行。
Flight-tracking data also showed B-52 bombers heading north from the Minot area in North Dakota into Canada, while others followed looping routes over Louisiana and Mississippi.
此外，一架B-1B“枪骑兵”轰炸机被追踪到在得克萨斯州西部上空飞行。
A B-1B Lancer bomber was also tracked over western Texas.
美国的核武力围绕三个分支构建，统称为核三位一体：陆基导弹、弹道导弹核潜艇和远程轰炸机。
America’s nuclear forces are built around three branches, known collectively as the nuclear triad: land-based missiles, ballistic missile submarines and long-range bombers.
陆基部分由部署在加固地下导弹井中的民兵三型洲际弹道导弹组成。
The land-based component consists of Minuteman III intercontinental ballistic missiles housed in hardened underground silos.
海上，潜艇携带核武装的三叉戟二型导弹，而B-52和B-2轰炸机提供空中分量。
At sea, submarines carry nuclear-armed Trident II missiles, while B-52 and B-2 bombers provide the airborne component.
周二下午至少有五架末日飞机被发现，今晨又有报道称有一架（资料图）这些力量共同使国家领导人拥有多种应对攻击的方式，即使核武力的一部分遭到打击，也有助于保留反击能力。
At least five doomsday planes were seen Tuesday afternoon, with another reported this morning (stock) Together, these forces give national leaders several ways to respond to an attack, helping preserve the ability to retaliate even if part of the nuclear force is targeted.
E-6B基于波音公司的商用707飞机，携带专门的通信设备，旨在维持国家领导人与核武力之间的联系。其设备包括用于与弹道导弹核潜艇进行极低频通信的长拖曳天线。
The E-6B, based on Boeing’s commercial 707 aircraft, carries specialized communications equipment designed to maintain contact between national leaders and nuclear forces. Its equipment includes long trailing wire antennas used for very-low-frequency communications with ballistic missile submarines.
该飞机还携带空中发射控制系统，可协助发射美国的陆基洲际弹道导弹。
The aircraft also carries an airborne launch control system that can facilitate the launch of America’s land-based intercontinental ballistic missiles.
与此同时，B-1B“枪骑兵”轰炸机仅使用常规武器。空军于1994年取消其核任务，并于2011年完成向纯常规状态的转换。
The B-1B Lancer, meanwhile, operates exclusively with conventional weapons. The Air Force eliminated its nuclear mission in 1994 and completed its conversion to conventional-only status in 2011.
飞行地图显示飞机移动情况，但并未确定其武器载荷，也未确认图中每架飞机都参与了“全球雷霆”演习。
The flight maps show aircraft movements, but do not establish their weapons loads or confirm that every aircraft pictured was participating in Global Thunder.
一系列航空通告划出了空域区块，为指定时段分配特定的天空区域，使管制员能够将计划活动与其他飞机分开。
A series of aviation notices set aside blocks of airspace, allocating defined areas of sky for specified periods, allowing controllers to separate planned activity from other aircraft.
与核演习最明确的关联是大西洋上名为“全球雷霆（橡树布拉沃）”的预留区域，从海面延伸至约25000英尺高度。
The clearest link to the nuclear exercise is an Atlantic reservation named ‘Global Thunder (Oak Bravo),’ extending from the ocean’s surface to approximately 25,000 feet.
该区域原定于美国东部时间10月27日周二上午10点至10月30日周五晚上11点运行。
It was scheduled to run from 10am Eastern on Tuesday, October 27, until 11pm Friday, October 30.
其他通告预留了大西洋、太平洋和佛罗里达州上空的领空，其中一则警告飞行员要“格外小心”。另外两则通告分别延长了米诺特空军基地的运行时间，并将怀特曼空军基地限制为仅处理公务。这些通告均未明确将这些措施与“全球雷霆”演习联系起来。
Other notices reserved airspace over the Atlantic, Pacific and Florida, with one warning pilots to exercise ‘extreme caution.’Separate notices extended operating hours at Minot Air Force Base and limited Whiteman Air Force Base to official business. None explicitly linked these measures to Global Thunder.
