EL SEGUNDO, Calif. -- U.S. Space Force’s Space Systems Command (SSC) and the Space Development Agency (SDA) launched the SDA’s Tranche 1 (T1) Transport Layer-E (T1TL-E) mission at 1:32 p.m. PDT today, aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base, Calif.
The National Security Space Launch (NSSL) program, under SSC’s System Delta 80 (SYD 80), successfully delivered the SDA’s 21 data transport T1 SVs into low Earth Orbit (LEO). These SVs will support the tracking of advanced missile threats by providing secure, low-latency, beyond-line-of-sight (BLOS) tactical communication links, delivering a resilient, optically-connected network of integrated capabilities to the warfighter at speed.
“The National Security Space Launch (NSSL) program team successfully executed a launch today for our Space Development Agency partners, helping build out another orbital plane for their communications layer,” said U.S. Space Force Col. Ryan Hiserote, SSC SYD 80 commander. (...)
