Relativity Space completes Terran R stage one structural qualification campaign
Company monthly report for July 2026. The stage one structural qualification test campaign is complete. The structural test stand, known internally as the Tender Loving Crusher, conducted lifecycle and burst pressure testing including 420 pressure cycles, 62 proof, stability and ultimate loading cases, and axial compression loading reaching 4.3 million pounds-force (19.4 million Newtons) while pressurised. The company states successful completion validates that the stage one tank is ready to withstand the loads of ground operations, launch and flight. The team released 1,130 flight parts and fully released the stage one shipping assembly, described as the culmination of more than two years of design work and marking full release of more than 11,000 stage one structures, fluids systems, avionics and harnesses. The first circumferential friction stir weld for a flight two tank was completed, and a carbon fibre composite panel was produced, laminated and cured in-house. The company also noted the US Space Force on-ramped Relativity into the National Security Space Launch Phase 3 Lane 1 programme in July.
