Members of @SemperCitiusSDA's Tranche 2 leadership team were recently at Rocket Lab's California headquarters to see T2TL-Beta in production. Eight of 18 spacecraft are on the floor right now, in build. Solar panels, structures, star trackers, reaction wheels, radios, flight software, avionics, launch dispenser — all built in-house. Proliferated architectures demand production at scale. Rocket Lab is all in on SDA's mission, and the action on our floor proves it. We're proud to be delivering this.
