Launch and Space Transportation Companies

This group gathers commercial companies whose primary business is building or operating launch vehicles and other space transportation systems, from established providers such as SpaceX, Blue Origin, United Launch Alliance and Rocket Lab to smaller launch vehicle developers, suborbital and reusable-vehicle ventures, and rocket engine manufacturers. It does not cover national government launch programs, which are grouped by region under their own national space agency, and it does not cover companies whose own primary business is satellite manufacturing, satellite operation, or human spaceflight and station services, grouped separately below even where such a company also builds a launch vehicle of its own.
