About

The LX-Class is one of York Space Systems’ family of flight-proven spacecraft platforms, built to help ensure the reliability and success of a customer’s mission. It is a 3-axis stabilized spacecraft engineered for mass manufacture and intended for use in satellite constellations. The LX-Class is designed to meet the most stringent mission capabilities and fits most dedicated launches, and it can leverage the ESPA-Grande rideshare accommodation for access to space. It sits alongside York’s S-Class and M-Class platforms in a shared bus family; York’s M-Class platform, for example, shares 75% of its technology with the S-Class and LX-Class buses, streamlining York’s supply chain across all the satellites it produces.
