GE Aerospace Space Systems

GE Aerospace (NYSE: GE, ~$200B market cap) is one of the world's largest aviation and aerospace technology companies, with space-relevant capabilities concentrated in power electronics, thermal management, and advanced manufacturing for satellite and launch vehicle applications. Following GE's strategic separation into three independent companies in 2023-2024 — GE Aerospace (aviation/defense), GEVernova (energy), and GE HealthCare — GE Aerospace retains the space systems business alongside its dominant commercial jet engine portfolio. Space capabilities include high-efficiency power conversion electronics (DC-DC converters, motor drives, power conditioning units) for satellite electrical power systems, thermal management hardware (heat exchangers, vapor cycle systems) for spacecraft thermal control, and additive manufactured metallic components produced using GE's proprietary DMLM (Direct Metal Laser Melting) process — the same technology that revolutionized jet engine component manufacturing is applied to space hardware to achieve complex geometries, weight reduction, and consolidated part counts impossible with conventional machining. GE's defense and space electronics division also contributes radiation-tolerant power electronics for military satellite platforms and launch vehicle components for US government programs. The company's Cincinnati-area engineering centers have collaborated with NASA on nuclear space power systems and electric propulsion pump-fed architectures.
