美國太空發展局正推進擴展型作戰人員太空架構,以建立分散式低軌衛星系統,提供全球飛彈預警與追蹤能力。L3Harris為主要承包商之一,去年12月獲得價值8.43億美元的合約,負責建造18枚第3批次追蹤衛星。

〔編譯陳成良/綜合報導〕美軍太空飛彈預警網再向前推進。美國國防承包商L3Harris Technologies已完成18枚新型飛彈追蹤衛星的初步設計審查,這批衛星未來進入軌道後,將用於提供近乎連續的全球飛彈預警與追蹤能力。
歐洲防務網站《Defence Industry》報導,L3Harris完成的是美國太空發展局(SDA)「追蹤層第3批次」(Tracking Layer Tranche 3,TRKT3)的初步設計審查。公司表示,審查確認了整套任務系統的基準設計,包括衛星、紅外線酬載、地面系統、通訊與網路等部分。

報導陳述,這18枚衛星將搭載紅外線感測器,並具備軌道上資料處理能力,可即時分析威脅資訊。L3Harris表示,衛星部署後將成為SDA「擴展型作戰人員太空架構」(Proliferated Warfighter Space Architecture)的一部分,執行全球飛彈預警與追蹤任務。
這項設計進度與L3Harris去年12月取得的合約相連。SDA當時授予L3Harris價值最高約8.43億美元(約新台幣268億元)的合約,建造18枚搭載紅外線感測器的第3批次追蹤衛星,作為分散式低軌衛星架構的一環。
TRKT3並非單一公司的衛星計畫。SDA去年12月分別與L3Harris、洛克希德‧馬丁(Lockheed Martin)、諾斯洛普‧格魯曼(Northrop Grumman)及火箭實驗室(Rocket Lab)簽約,合計建造72枚第3批次追蹤衛星,總合約金額約35億美元(約新台幣1121億元),目標是擴大全球飛彈預警與追蹤覆蓋。
與前一批次相比,TRKT3的設計也出現更大幅度的酬載調整。據《Aviation Week》報導,L3Harris主管表示,第3批次為符合近乎連續全球飛彈預警與追蹤需求,酬載及其性能都需要重大更新。
L3Harris表示,這18枚衛星完成後續工作並進入軌道,將提供近乎連續的全球飛彈預警與追蹤。這項能力屬於美國分層飛彈防禦架構的一環,但目前這批衛星仍處於設計與開發階段。

British police detained five men and examined suspected explosives found near RAF Fairford in England, as counterterror detectives probe potential links to Iran, Russia, or militant groups.

Beijing deployed its WZ-7 high-altitude reconnaissance drone in the South China Sea for the first time during joint drills near the disputed Scarborough Shoal.

Lithuania held the annual largest national mobilization exercise "Vitis Dome 2026" from September 25 to October 3, mobilizing 14 ministries, 60 local governments, military, police, medical and other units. About 3,000 civil servants and 1,000 volunteers participated to verify wartime response capabilities such as resident evacuation, protection of critical infrastructure, diversion of military and civilian traffic, and reception of allied forces. The exercise adopted a table-top approach The exercises and actual military drills were carried out in parallel, and the scenario design was based on current security threats and conflict experience. Resident evacuation process drills were carried out on September 26, and the response to critical infrastructure and the reception capabilities of allied forces when critical infrastructure was attacked by air threats were tested on September 29. The government emphasized that this is a test of the resilience of the national mobilization system, aiming to ensure that key national functions are not interrupted in wartime when information is incomplete, resources are limited, and communications are blocked.

The National Army will implement the "urgent ammunition replenishment" procurement plan from this year to 2031. The total budget for six years is as high as 27.588945 trillion yuan. The goal is to increase the ammunition combat readiness inventory from the current 30 days to 120 days to cope with high-intensity consumption and foreign aid supply disruptions during wartime.

North Korea's recent drills combine "swarm attack" tactics with drones, hypersonic missiles and multiple launch rockets, aiming to suppress air defense systems through multi-directional saturation attacks. Experts pointed out that this move follows the experience of Ukraine and the Middle East battlefields, which may change the military balance on the Korean Peninsula and put pressure on the defense inventories of U.S. allies.

The US, Denmark, and Greenland have signed a defence agreement allowing for the construction of two new military bases in Greenland. The pact, which updates a 1951 deal, aims to strengthen NATO's Arctic presence and counter potential cooperation between Beijing and Moscow.
