弗吉尼亚州阿灵顿，3月17日（路透社）- 该项目负责人周二表示，”金穹”（Golden Dome）导弹防御系统的预算已增至1850亿美元，较此前增加100亿美元，以加速关键天基能力建设。此外，洛克希德·马丁、雷神技术公司（RTX）和诺斯罗普·格鲁曼公司已加入担任主要承包商。
“金穹”计划旨在扩展地基防御系统，包括拦截导弹、传感器和指挥控制系统，同时新增天基元素，用于探测、跟踪并可能反击来自轨道的来袭威胁。这些元素将包括先进卫星网络以及仍存在争议的轨道武器。

“我们被要求加速部分天基能力建设，” “金穹”项目主管、太空军将领迈克尔·盖特林（Michael Guetlein）在弗吉尼亚州阿灵顿举行的麦卡利斯防务项目会议上表示。他指出，三项计划将从追加资金中受益：先进导弹跟踪计划、太空数据网络以及高超音速和弹道跟踪太空传感器系统（HBTSS）。
HBTSS是一个天基传感器系统，旨在探测和跟踪高超音速及弹道导弹威胁。将其纳入加速资金计划，表明五角大楼急于部署持续的高空跟踪能力，以应对对手不断扩大的高超音速武器库。

1850亿美元的预算涵盖了盖特林所说的”目标架构”，即未来十年内将交付的全能力系统。
盖特林驳斥了外界关于该项目潜在成本超过1万亿美元的估算，称这些数字是将为海外作战设计的昂贵独立战场系统应用于 homeland defense（本土防御）任务，而后者需要根本不同且成本更低的方法。
“他们并没有在估算我正在打造的系统，”盖特林表示。
盖特林称指挥控制系统是”金穹”的”制胜关键”。他描述了一个由六家企业自发组建的九公司联盟，后来洛克希德·马丁、RTX和诺斯罗普·格鲁曼加入成为主要合作伙伴。
该联盟每周四晚间向盖特林简报汇报，并可投票将表现不佳的成员逐出联盟。
将军指出，天基拦截器是该项目风险最高的环节，称可扩展性和可负担性是核心挑战。他表示，定向能武器和下一代人工智能代表了降低”单次杀伤成本”并增加有效载荷深度的最有前景技术。

US expands Golden Dome cost estimate to $185 billion, enlists top defense firms
March 17, 2026 5:29 PM UTC / Reuters
ARLINGTON, Virginia, March 17 (Reuters) – The price tag for the Golden Dome missile defense shield has grown to $185 billion, up $10 billion, to accelerate key space-based capabilities, the program’s director said on Tuesday, adding that Lockheed Martin, RTX and Northrop Grumman have joined as prime contractors.
Golden Dome envisions expanding ground‑based defenses such as interceptor missiles, sensors and command‑and‑control systems while adding space‑based elements meant to detect, track and potentially counter incoming threats from orbit. These would include advanced satellite networks and still‑debated weaponry in orbit.

“We were asked to accelerate some space capabilities,” Golden Dome’s manager, Space Force General Michael Guetlein, told the McAleese Defense Programs Conference in Arlington, Virginia. He identified three programs that would benefit from the additional funding: the Advanced Missile Tracking Initiative, a space data network, and the Hypersonic and Ballistic Tracking Space Sensor, known as HBTSS.
HBTSS is a space-based sensor system designed to detect and track hypersonic and ballistic missile threats. Its inclusion in the accelerated funding package signals the Pentagon’s urgency in fielding a persistent overhead tracking capability as adversaries expand their hypersonic arsenals.

The $185 billion figure covers what Guetlein called the “objective architecture,” a full-capability system to be delivered over the next decade.
Guetlein rejected outside estimates that have placed the program’s potential cost above $1 trillion, arguing those figures are based on applying expensive, self-contained battlefield systems designed for overseas combat to a homeland defense mission that requires a fundamentally different and cheaper approach.
“They’re not estimating what I’m building,” Guetlein said.
Guetlein called the command-and-control system Golden Dome’s “secret sauce.” He described a nine-company consortium that began as a self-formed group of six firms before Lockheed Martin, RTX and Northrop Grumman joined as prime partners.
The consortium briefs Guetlein every Thursday evening and can vote underperforming members out of the group.
The general identified space-based interceptors as the program’s highest-risk element, citing scalability and affordability as the central challenge. He said directed energy weapons and next-generation artificial intelligence represent the most promising technologies for driving down cost-per-kill and increasing magazine depth.
