YSS

York Space Systems Inc.

A Colorado aerospace company that builds standardized, plug-and-play satellites rather than expensive one-off spacecraft. Its S-CLASS, M-CLASS, and LX-CLASS "buses" carry payloads for national-security, earth-observation, and communications missions. Founded in 2012 by aerospace veteran Dirk Wallinger, it is often described as the "iPhone of satellites"—customers snap their sensors and gear onto York's mass-produced bodies instead of designing from scratch.
