Reusable launch turned space from a national-program-only domain into a commercial supply chain. Six layers, from the rockets that get mass to orbit, through the satellite manufacturers and constellation operators, into the connectivity and earth-observation businesses that sell the data — plus the defense-space programs and the parts suppliers underneath all of it.
Launch at the apex. Components at the foundation. Every US-listed public company actually operating in between.
The companies actually getting payloads to orbit. Rocket Lab as the only pure-play public small-launch provider, Lockheed Martin and Boeing through their United Launch Alliance joint venture for heavy national-security missions.
Manufacturers of the satellite buses and integrated spacecraft sold to commercial operators, government, and intelligence-community customers. Rocket Lab's vertical integration into Photon, plus the traditional aerospace primes.
Constellation operators selling voice, data, IoT, and direct-to-device connectivity. Includes Iridium's L-band global voice network, AST SpaceMobile's direct-to-cellphone constellation, Viasat's broadband fleet, and Globalstar's Apple-anchored services.
Operators of remote-sensing constellations selling imagery, change detection, and geospatial intelligence to commercial, defense, and intelligence customers. Planet's daily global scans and BlackSky's high-revisit imagery and analytics.
Prime contractors with major Space Force, Missile Defense Agency, and National Reconnaissance Office programs — missile-warning constellations, GPS modernization, secure communications, and the next-generation overhead persistent infrared layer.
Sub-tier suppliers of the avionics, sensors, RF gear, and electronics that get integrated into spacecraft and launch vehicles — Teledyne's space-qualified instruments, HEICO's aftermarket aerospace parts, and Kratos's satellite and command-and-control software.
