I never tire of bringing space leaders here. After bringing Vice Chief of Space Operations Gen. Bratton to @319thRW, we received a briefing on the floor of @SemperCitiusSDA which reinforced what I’ve long said: Grand Forks is a powerhouse for America’s space mission.
It was valuable for Gen. Bratton to see the capabilities at GFAFB, especially as @POTUS plans major investments in the @USSpaceForce. What’s being built here is unmatched, and I was honored to join Gen. Bratton in highlighting the expertise and innovation coming out of Grand Forks.
SDA announced a firm-fixed price award under HALO, Europa Track 1 to @capellaspace to demo advanced tactical waveform, adaptive beamforming, & secure tactical comms in LEO. Capella is among the original 19 #HALO pool members. https://t.co/9SfoyVWRam

In the summer of 2025, SDA successfully launched the "Dragoon" demo satellite from Vandenberg Space Force Base, California. @YorkSpaceSystem built this prototype satellite for the Tranche 1 Experimentation and Demonstration System (T1DES).
#SemperCitius #SDADelivers2025 #PWSA
SDA’s Tranche 0 continued to show success in 2025 with the demonstration of optical space-to-ground (S2G) communications using @YorkSpaceSystem and @SpaceX satellite vehicles, and SDA prototype optical ground terminals.
#SemperCitius #SDADelivers2025 #PWSA
#HappyBirthday, @USSpaceForce. We are proud to be part of the Space Force team delivering the #PWSA as part of the #USSF holistic hybrid space architecture to support joint force operations and ensure warfighting success across all domains.
