Terran R build is continuing to ramp up this fall. From avionic builds to expanding of our machine shop capabilities and more. 🔥In prop, teams completed assembly of the second Aeon R engine for first flight and reduced average cycle times across key engine components by 50%. 💻The avionics team is building the flight hub box, which will serve as Terran R’s central node for routing data and distributing power to critical systems. 🚀Welding of the first stage tank is progressing with 3 circumferential friction stir welds now complete.

From factory floor to launch site, the Terran R program is gaining serious momentum. Here’s the latest from May across design, build, test, and launch: 🖌️ Design: 17+ component-level Critical Design Reviews completed—rapidly releasing simpler parts like trays and manifolds ahead of structural assembly. ⚒️ Build: The LOX dome was successfully loaded onto the CFSW for its second weld, and the stage 2 transfer tube is now being welded—key steps toward completing the second stage tank. 🔥 Test: Aeon R engine qualification officially kicked off Stennis Space Center with 11+ hot fires in the books in May. 🚀Launch: Cape Canaveral’s LC-16 saw construction milestones—like the completion of the east flume wall in the diverter pit. Plus, we welcomed Robin Petitprez as SVP of Manufacturing & Supply Chain, strengthening our ability to industrialize Terran R at scale.
