Relativity Space(@relativityspace):Engine integration has begun! The first Aeon R engines are now installed on Terran R’s thrust structure. 💪 The thrust structure will house 13 Aeon R engines, each producing 269,000 lbf of sea level thrust for a combined thrust of 3,497,000 lbf at liftoff. 🔥 Each engine has successfully completed acceptance testing before installation on the vehicle. 🌀 Custom ground equipment precisely positions each engine for installation, then will rotate the fully integrated thrust structure into position for mate with stage 1. One step closer to a fully integrated stage 1!
