“We have proven out the timeliness latency of the fire control loop with those systems as well as the sensitivity of those systems to close the loop,” Collins said, describing successful prototype tests and planned algorithm updates to improve track quality.

Collins said MDA has worked in parallel with the Space Force and the Space Development Agency and that HBTSS‑like requirements are being incorporated into the proliferated warfighting space architecture. He said follow‑on tranches will build up an operational hypersonic‑tracking layer in the years ahead.

Senators and witnesses agreed that a resilient, proliferated space sensing layer is foundational to future missile defense efforts, especially against maneuverable hypersonic threats. Collins said MDA will continue to prototype discriminating space sensors for ballistic missile defense while the Space Force operationalizes the capability.

The subcommittee did not take formal action on space sensor programs during the hearing.","mediaType","Video","parentTitle","To receive testimony on the Department of Defense missile defense activities in review of the Defense Authorization Request for Fiscal Year 2026 and the Future Years Defense Program","oneSentenceSummary","Missile Defense Agency director Lieutenant General Collins told the Senate subcommittee that HBTSS/ABTSS prototype satellites have proven timeliness and sensitivity for hypersonic tracking in tests and that Space Force/Space Development Agency tranches will build an operational layer.","taxTitle","Armed Services: Senate Committee, Standing Committees - House & Senate, Congressional Hearings Compilation, Legislative, Federal","taxId",1987,"location","","headline","shortSummary",{"_33":76,"_35":36,"_37":38,"_39":77,"_41":78,"_43":79,"_45":80,"_47":81,"_49":82,"_51":83,"_53":84,"_55":56,"_57":58,"_59":85,"_61":62,"_63":64,"_65":86,"_67":68,"_69":70,"_71":72,"_73":72,"_74":72},6055775,"Pentagon Official: Guam Defense System JPO Established; Initial Capability Targeted for 2027, Cost Estimated at $8 Billion",134,1702000,1836000,"/Search/View?dp=1&key=3315874-71447b544409fec876378f8a6bead1ab&start=1702&end=1836","https://assets.pipeline.soar.com/3315874-71447b544409fec876378f8a6bead1ab/thumbnail_1702000.jpg","/articles/6055775/Pentagon-Official-Guam-Defense-System-JPO-Established-Initial-Capability-Targeted-for-2027-Cost-Estimated-at-8-Billion","https://secure.pipeline.soar.com/6055775-7cea119dc91aa4ac8aebf088604f696b/orig.mp4?Expires=1773743915&Signature=oFrXE4I7KSgojcrWZvytyIEAJ5LrExZ-BTfm-IcNHK7iIZ5qmrNuU4sRJkfW0R1xxavzW7F7H6QDNnS0advx354OHlNFHsJj5myrXMLnLSqHPzjHRnQpVl5eptVJo98wLXVfa52u6D~cTPcpX-DKb4Bth9n4Tsqogty2yRd8PqdoXwIsyreAvPj1fFbvslDN3hUi9OMzcGP2xiUtCpCPa40RpC4yKBermp3TO5184K~auvOcTp3UPg9G7sZPqTsZ7DqNj~y~P-Gv2xj93hDt5hbdpo9P4CeExrTgq3VJN3xOWEd3jw3en3Vq-NeInub55J4Ly4CqRCKVNGM2IjQPUQ__&Key-Pair-Id=KUT5TJCACFTXG","WASHINGTON — Lieutenant General Rasch, testifying for Army senior leadership, told a Senate Armed Services subcommittee that the Department of Defense established the Guam Defense Systems Joint Program Office (JPO) in February 2024 and is aiming for an initial capability increment in 2027.

“The Joint Program Office is charged with synchronizing the development, testing, fielding, and sustainment of the Guam Defense System components in the integration of the corresponding command and control systems,” Rasch told the panel, describing the JPO’s role in developing a joint integrated battle manager to allow service systems to operate as a unified architecture.

Rasch said the department expects the Guam defense investment — comprised of systems the services are building and placing on the island — to total about $8,000,000,000 across the services. He said that figure isolates services’ defense system costs from other DOD and recovery spending on Guam.

Witnesses said Guam’s architecture combines Navy Aegis capabilities, Missile Defense Agency systems, Army IBCS and Army/Task Force Talon THAAD assets, and Air Force command‑and‑control. Rasch and other witnesses emphasized integration of those service systems, not simply co‑location, as the critical task.

Senators pressed on timeline and sustainment. Rasch told the subcommittee the department is working to ensure the force structure, sustainment tail and personnel training are in place so the capability can be sustained “not just for a day, but for years.” He also said the Guam National Guard has provided security support for deployed THAAD elements.

No formal committee action followed; senators said they expect additional oversight as Guam efforts proceed.","Lieutenant General Rasch told the subcommittee the Guam Defense Systems Joint Program Office was stood up in February 2024, is synchronizing service systems and command-and-control, and that the department estimates roughly $8 billion of service investments will be located on Guam; the initial capability increment is planned for 2027.",{"_33":88,"_35":36,"_37":38,"_39":89,"_41":90,"_43":91,"_45":92,"_47":93,"_49":94,"_51":95,"_53":96,"_55":56,"_57":58,"_59":97,"_61":62,"_63":64,"_65":98,"_67":68,"_69":70,"_71":72,"_73":72,"_74":72},6055780,"Senate Subcommittee Questions Feasibility, Cost and Timeline for 'Golden Dome' homeland missile-defense effort",2799,999000,3798000,"/Search/View?dp=1&key=3315874-71447b544409fec876378f8a6bead1ab&start=999&end=3798","https://assets.pipeline.soar.com/3315874-71447b544409fec876378f8a6bead1ab/thumbnail_999000.jpg","/articles/6055780/Senate-Subcommittee-Questions-Feasibility-Cost-and-Timeline-for-Golden-Dome-homeland-missile-defense-effort","https://secure.pipeline.soar.com/6055780-47fe802baad8e9dbd77898f7bef42720/orig.mp4?Expires=1773743915&Signature=S85HJvJ~RN3gBQmsLEd4uArY~uqY9NdX0MjVVJiWTKBVlaW0xIP0ca2~SC-CwQYRJh4ID5ltThvkoh1UjQMAX4ot8DfOOs5cZKEnCRXGoKuOXAhyyZks6CWNwJeUnd6q1HzMIqAdGBhEVovjLs4t8EwzEqjNqy-I7x9SMGqK9nPkfnBZ0mZMfZRSwE7P~R67LehJ~~9SkI0OYM9BXq5ivTIZIM93WlRmwUu6Qb8RjHk0lH9XMfp6JwGTbrj0FiM~5QNbd90HFPjCjBpVDQgYmJkaIlUvGPKzKb0A1swJPwvP2Ut6~V7J-mHvoMT4ZJvWmrwKu6jCfkRdXUjBeW46hg__&Key-Pair-Id=KUT5TJCACFTXG","WASHINGTON — Senior Department of Defense officials told a Senate Armed Services subcommittee that the department is developing design options for an integrated homeland air and missile-defense architecture called “Golden Dome,” but that key technical decisions and funding remain pending with the White House and the FY26 budget process.

“The President has mandated that The United States will develop and field a next generation missile defense shield to provide for the common defense of our citizens and the nation and deter, defend against and defeat any foreign aerial attack on the homeland,” Ms. Yaffe said in her opening statement, summarizing the policy directive conveyed to the Office of the Secretary of Defense.

The subcommittee heard that the department completed a 60‑day study and briefed options to senior leaders; those options were further refined by technical experts and have been provided to the Secretary of Defense and the White House, Ms. Yaffe said. She added the administration is expected to announce decisions in conjunction with the President’s budget request.

Senator King pressed witnesses on feasibility and scale, asking whether a deterrence-by-denial approach could realistically stop a large, coordinated campaign of thousands of missiles from a peer power. “I’m a great believer in deterrence. I’m just not sure deterrence by denial is realistic in this setting. Convince me,” King said.

Officials described Golden Dome as an integrated, layered approach that requires dramatic improvements in domain awareness — seabed to space — and in interceptor and non‑kinetic options such as directed energy. General Guillot, commanding NORTHCOM, told the panel that “the domain awareness layer of Golden Dome is the most critical” and emphasized an undersea, ground, air and space sensing architecture to detect and track advanced threats.

Lieutenant General Collins of the Missile Defense Agency said prototype space sensors have demonstrated promising track quality and latency for hypersonic threats and that those sensor requirements are being incorporated into follow‑on space architectures. Collins also said production lines for some interceptors remain open following recent operational use overseas and supplemental replenishment funding.

Senators and witnesses repeatedly emphasized that architecture choices and the pace of deployment are contingent on forthcoming budget decisions. King and others questioned whether the costs of scaling a Golden Dome‑like architecture nationwide would be commensurate with likely effectiveness against evolving hypersonic and maneuverable threats.

The subcommittee took no formal votes. Senators signaled intent to hold follow‑on hearings after the administration’s budget and the Secretary’s decisions on the Golden Dome architecture are released.","Witnesses told the Senate Armed Services subcommittee that work is underway to design an integrated homeland air and missile-defense architecture called \"Golden Dome,\" but officials and senators raised questions about scale, timelines, and costs and said final architecture decisions are tied to the President’s budget.","actionData","errors"]
