Propulsion & Engines
Rocket propulsion companies develop the engines and motors that power launch vehicles and spacecraft. From SpaceX's Raptor methane engines to RTX's legacy solid motors, the sector is being transformed by 3D-printed engines (Relativity, Agnikul), reusable designs, and next-generation electric/ion propulsion for in-space maneuvers.
