We build rockets to launch small satellites
ABL Space Systems was founded in 2017 by former SpaceX engineers Harry O'Hanley and Dan Piemont in El Segundo, California. The company developed the RS1 small-lift launch vehicle and the GS0 containerized ground system, designed to enable launch from any flat pad globally. After two failed RS1 launch attempts, the company rebranded as Long Wall in early 2025 to focus on missile defense programs for the US Department of Defense under existing STRATFI contracts.
