LC-16 is continuing its transition from construction to activation, with major infrastructure and ground systems work advancing across the site. ✓ Water tower reached its final height of 305 feet ✓ Lightning protection system erection continues across the site ✓ 220,000-pound bridge crane installed in the HIF cleanroom ✓ HIF outfitting underway with ductwork, offices, and facility systems progressing ✓ Launch table and transporter-erector infrastructure continue advancing

From engine qualification to advancing stand readiness, teams are preparing for a busy season of Terran R testing. 📍NASA Stennis, MS ✔️ Aeon V second stage engine qualification campaign completed ✔️ Aeon R first stage engine acceptance testing continues ✔️ Initial startup of the environmental control system completed ✔️ LOX flush performed on the A2 top deck ✔️ Over 11,000 welds completed on A2

Across the factory, teams advanced major Terran R structures, from stage 2 integration and shipment to propulsion, thrust structure, interstage, and stage 1 qualification hardware. ✓ Shipped stage 2 from Long Beach to NASA Stennis ✓ Installed outer engine LOX and fuel feedlines on the thrust structure ✓ Advancing stage 1 qualification article ahead of test ✓ Progressed interstage barrels through mechanical assembly and machining

The Terran R program entered a new phase in May as stage 2 rolled out of Long Beach and began its journey to NASA Stennis. 🏗️ Build: Completed stage 2 integration while advancing thrust structure, interstage, and stage 1 qualification hardware. 🔥 Test: Aeon V second stage engine completed its qualification campaign, hitting key service life, duration, and start milestones for flight one. 🌴Launch: Water tower reached its final height at 305 feet; lightning protection system erection continued

Test campaigns and infrastructure continue scaling alongside Terran R flight hardware. 📍 NASA Stennis, MS ✔️ Aeon R acceptance testing continues, with more engines accepted for flight ✔️ Aeon V completed full-duration mission duty cycles and reached key service life milestones ✔️ First vertical LNG pump installed, capable of supplying 150,000 gallons in 30 minutes

📍 Long Beach, CA ✔️ Software run-for-record testing underway following completion of the stage two HITL build ✔️ Structural test stand modifications nearing completion ahead of stage one qualification testing ✔️ Additional powder bed fusion and CNC machines installed in the expanded machine shop

Terran R integration is accelerating across flight hardware and factory infrastructure. ✓ Stage two avionics trays, boxes, harnesses, valves, and raceways installed ✓ Low-voltage checkouts began, integrating avionics hardware with flight software ✓ All first stage Aeon R flight engines for flight one have been manufactured, assembled, and shipped ✓ Stage one qualification article welding is complete ✓ In-house battery production ramping, with units progressing through flight build and acceptance testing

Terran R moved closer to flight readiness in April with key integration, test, and launch infrastructure milestones. 🏗️ Build: Stage two integration advanced with avionics, harnesses, valves, and raceways installed. All first stage Aeon R engines for flight one have been manufactured, assembled, and shipped. 🔥 Test: Teams began software run-for-record testing on the completed stage two HITL build, while Aeon V reached key service life milestones during full-duration mission duty cycles. 🌴 Launch: At LC-16, the water tower and lightning protection systems rose as launch site activation work continued across the LOX farm, water systems, and more.

LC-16 is rapidly evolving into the operational hub for Terran R launch, recovery, and reuse. ✓ Transporter-erector strongback delivered and undergoing outfitting ✓ Water tower raised to 180 ft with continued lifting underway ✓ Two 246,000-gallon LNG tanks installed to provide densified propellant for the stages

Test campaigns and infrastructure are scaling alongside hardware production. 📍 @NASAStennis ✔️ Aeon V second stage engine testing, including a 526.5-second endurance demonstration ✔️ Aeon R first stage engine acceptance testing continues ✔️ Hangar roof structure completed with sheeting installation underway ✔️ Live ring lift installation complete ✔️ Fluid lines being machined and routed ✔️ Flume work progressing with new service platforms delivered
