2026年7月16日，SpaceX於加利福尼亞州范登堡太空基地成功發射了「第1批傳輸層E」(Tranche 1 Transport Layer E)任務。
On July 16, 2026, SpaceX successfully launched the Tranche 1 Transport Layer E mission from Vandenberg Space Force Base, California.
該任務使用獵鷹9號(Falcon 9)火箭，將21顆衛星送入近地軌道，為美國太空發展局(SDA)服務。
Using a Falcon 9 rocket, the mission carried 21 satellites into low-Earth orbit for the U.S.
這些衛星是「擴散式戰鬥人員太空架構」(PWSA)的關鍵組成部分，該網路旨在提供具備韌性的全球軍事通信與飛彈追蹤能力。
Space Development Agency (SDA).
此次發射意義重大，因為它結束了SDA長達九個月的暫停期，該暫停期是為了修復早期衛星中發現的硬體與軟體問題。
These satellites are a critical part of the Proliferated Warfighter Space Architecture (PWSA), a network designed to provide resilient, global military communications and missile tracking.
此任務展現了SpaceX的可靠性，其第一級推進器完美降落在太平洋上的無人船上。
This launch was particularly significant as it ended a nine-month pause in SDA operations, which had been necessary to fix hardware and software issues identified in earlier satellites.
SDA正從傳統的大型衛星轉向低軌道的小型衛星網路，這使得對手更難干擾該系統。
The mission showcased SpaceX’s reliability, as the first-stage booster landed perfectly on a droneship in the Pacific Ocean.
目前，該機構已將大約一半計畫中的傳輸層衛星送入軌道，距離最終154顆衛星的目標更近了一步。
The SDA is shifting from traditional, large satellites to a network of smaller ones in lower orbits, making the system more difficult for adversaries to disrupt.
