華盛頓消息：美國太空部隊成功地為其受保護的衛星通信系統提供了五個計劃中的軟件更新中的第四個，使國際伙伴能夠訪問新功能。
先進的超高頻系統為高優先級軍事通信提供了可生存、受保護的抗干擾通信能力。作為MILSTAR的繼任者，該星座旨在使美國總統、國家安全委員會和聯合作戰指揮官等高級軍事領導人能夠控制戰略和戰術力量，即使在核戰爭期間也是如此。第六顆也是最后一顆AEHF衛星于2020年3月發射升空。四個國際伙伴——加拿大、英國、荷蘭和澳大利亞——也使用AEHF。
在 2015 年實現初始作戰能力后，該計劃的任務規劃元素與洛克希德·馬丁空間公司簽約開發五個軟件功能插入增量，為不斷增長的用戶提供額外的帶寬和系統效率。前三個增量分別于2017年、2018年和2019年投入作戰使用。
第六顆先進極高頻衛星預計將于今年年底獲得運行驗收。
在7月21日的一份聲明中，美國太空和導彈系統中心宣布，第四批增量已交付5月19日投入使用，作戰基線于6月25日更新。最新的軟件更新提供了任務的重新規劃，并允許國際合作伙伴訪問和控制衛星的協議消息。
“AEHF任務規劃元素增強是美國太空部隊以相關速度逐步向我們的戰斗機守護者和國際伙伴提供實地作戰能力的一個很好的例子，”洛馬公司空間生產部門指揮和控制系統部高級物資主管芭芭拉·貝克說。
第五個也是最后一個增量正在開發中，預計將在2022年12月投入作戰使用。SMC表示，該更新將提供加密規劃、全球超高頻超視線終端以及快速適應性規劃和態勢感知。
Space Force delivers software upgrades to satellite communications system

WASHINGTON — The U.S. Space Force successfully delivered the fourth of five planned software updates to its protected satellite communications system, enabling international partners to access new features.
The Advanced Extremely High Frequency system provides a survivable, protected, anti-jam signal for high-priority military communications. As the successor to MILSTAR, the constellation is designed to enable high-level military leaders such as the president, the National Security Council and unified combatant commanders to control strategic and tactical forces, even in the midst of a nuclear war. The sixth and final AEHF satellite was launched in March 2020. Four international partners — Canada, the United Kingdom, the Netherlands and Australia — also use AEHF.
After achieving initial operational capability in 2015, the program's Mission Planning Element contracted with Lockheed Martin Space to develop five software capability insertion increments to provide the additional bandwidth and system efficiencies for the growing number of users. The first three increments were operationally accepted in 2017, 2018 and 2019, respectively.
The sixth Advanced Extremely High Frequency satellites is expected to receive operational acceptance by the end of the year.
In a July 21 statement, the Space and Missile Systems Center announced that the fourth increment had been delivered to operations May 19, with the operational baseline updated on June 25. This latest software update provides endurance mission re-planning and allows international partners to access and control protocol messages for the satellites.
“The AEHF Mission Planning Element enhancements are a great example of the U.S. Space Force ability to incrementally field operational capability to our warfighter Guardians and international partners at the speed of relevance,” said Barbara Baker, senior materiel leader for the Space Production Corps Command and Control Systems Division.
The fifth and final increment is in development and is expected to be operationally accepted in December 2022. That update will provide crypto planning, Worldwide Extremely High Frequency Beyond-line-of-Sight Terminal and Rapid Adaptive Planning and Situational Awareness, according to SMC.
