Hardware across the vehicle continues to advance through test. 📍 Long Beach, CA The first stage downcomer completed its full acceptance test campaign. This flight-critical component, which routes liquid oxygen from the tank to the engines, is now cleared for integration. 📍 NASA Stennis, MS Stage 2 is back in the hangar after completing cryoproof and COPV proof testing. Post-test inspections are underway ahead of Aeon V installation. A2 is being prepped for hot fire, with LOX farm flushes and heat exchanger activations. On the R stand, acceptance testing of flight 2 Aeon R engines is underway.

Terran R hardware is advancing across multiple fronts, with integration work progressing on stage one and production scaling for future vehicles. ✓ All 13 flight one Aeon R sea-level engines installed onto the thrust structure ✓ All nominal joiners and external stringers approaching completion on stage one ✓ Both interstage barrels were painted and stacked to form the full structure ✓ All flight two barrels complete, first circumferential friction stir welds executed on the flight two stage one tank ✓ Flight three panel fabrication more than halfway complete

With all 13 Aeon R engines installed on the thrust structure and stage two heading towards hot fire, August was a big month for Terran R. 🔩 Build: All 13 Aeon R engines were installed onto the thrust structure. Stage one integration is advancing and both interstage barrels were stacked. Flight two barrels are complete and flight three production has begun. 🧪 Test: Stage two completed cryoproof and COPV proof testing and is now being readied for Aeon V engine installation ahead of hot fire. 🏗️ Launch: Flame diverter installation is underway at the pad, the engineering support building opened, and HIF outfitting continues.

The infrastructure required to launch a rocket of Terran R’s class is immense. At LC-16, we’re moving fast. ✓ Horizontal integration facility (HIF) is energized. This building will house Terran R's stages to be mated and prepared for launch ✓ 135 ton assembly room cranes completed their first proof load tests. These cranes will lift the vehicle for mate ✓ Transporter erector (TE) upper strongback was moved into the assembly room. This is part of the system that will transport Terran R to the pad and raise it vertical ✓ Permanent site power was activated with two dedicated 22-kilovolt feeds. This powers launch operations across the site

Test campaigns are building momentum, with major milestones logged across sites in July. 📍 Long Beach, CA ✔️ Stage one structural qualification campaign complete ✔️ 420 pressure cycles, 62 loading cases, and 4.3 million lbf axial compression ✔️ Stage one downcomer for flight completed first phase of acceptance testing

📍 NASA Stennis, MS ✔️ Second stage lifted and mated onto the A2 stage test stand ✔️ Cryoproof and COPV proof testing complete ✔️ Aeon V engine completed acceptance testing, wrapping up all flight one engine testing

Terran R hardware is advancing across multiple fronts, with integration work progressing on the stage one flight article and momentum building for the next vehicle. Key highlights from July: ✓ Fully released the stage one shipping assembly, comprised of more than 11,000 parts ✓ First wet installs of external stringers completed on the interstage forward barrel ✓ Outer engine feedlines installed, fluids testing underway on the thrust structure ✓ Flight one Aeon R engines prepared for thrust structure installation ✓ First circumferential friction stir welds completed for a flight two tank

Throughout July, Terran R continued advancing toward first flight, with the stage one structural qualification campaign complete and stage two testing kicking off at NASA Stennis. 🔩 Build: The stage one shipping assembly was fully released, with work across the stage one flight article progressing alongside flight two tank production and welding. 🧪 Test: Completed the stage one structural qualification campaign in Long Beach. Over at NASA Stennis, stage two completed cryoproof and COPV proof testing. 🏗️ Launch: At LC-16, the HIF was energized, the assembly room crane passed its first proof load test, and the transporter erector upper strongback was moved into the assembly room.
