華盛頓消息：美國太空部隊(duì)成功地為其受保護(hù)的衛(wèi)星通信系統(tǒng)提供了五個(gè)計(jì)劃中的軟件更新中的第四個(gè)，使國際伙伴能夠訪問新功能。
先進(jìn)的超高頻系統(tǒng)為高優(yōu)先級軍事通信提供了可生存、受保護(hù)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(tǒng)、國家安全委員會和聯(lián)合作戰(zhàn)指揮官等高級軍事領(lǐng)導(dǎo)人能夠控制戰(zhàn)略和戰(zhàn)術(shù)力量，即使在核戰(zhàn)爭期間也是如此。第六顆也是最后一顆AEHF衛(wèi)星于2020年3月發(fā)射升空。四個(gè)國際伙伴——加拿大、英國、荷蘭和澳大利亞——也使用AEHF。
在 2015 年實(shí)現(xiàn)初始作戰(zhàn)能力后，該計(jì)劃的任務(wù)規(guī)劃元素與洛克希德·馬丁空間公司簽約開發(fā)五個(gè)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(tǒng)效率。前三個(gè)增量分別于2017年、2018年和2019年投入作戰(zhàn)使用。
第六顆先進(jìn)極高頻衛(wèi)星預(yù)計(jì)將于今年年底獲得運(yùn)行驗(yàn)收。
在7月21日的一份聲明中，美國太空和導(dǎo)彈系統(tǒng)中心宣布，第四批增量已交付5月19日投入使用，作戰(zhàn)基線于6月25日更新。最新的軟件更新提供了任務(wù)的重新規(guī)劃，并允許國際合作伙伴訪問和控制衛(wèi)星的協(xié)議消息。
“AEHF任務(wù)規(guī)劃元素增強(qiáng)是美國太空部隊(duì)以相關(guān)速度逐步向我們的戰(zhàn)斗機(jī)守護(hù)者和國際伙伴提供實(shí)地作戰(zhàn)能力的一個(gè)很好的例子，”洛馬公司空間生產(chǎn)部門指揮和控制系統(tǒng)部高級物資主管芭芭拉·貝克說。
第五個(gè)也是最后一個(gè)增量正在開發(fā)中，預(yù)計(jì)將在2022年12月投入作戰(zhàn)使用。SMC表示，該更新將提供加密規(guī)劃、全球超高頻超視線終端以及快速適應(yīng)性規(guī)劃和態(tài)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.
