ZORA Reentry Systems s. r. o.

We are a Slovak deep-tech company based in Košice, specializing in the research, development, and manufacturing of high-performance carbon/phenolic composite materials and components for the aerospace sector. 

The company was founded by key members of the HARTS team, selected for the ESA REXUS programme, and is among the first startups supported by ESA BIC Slovakia. Our mission is to establish Europe's first dedicated commercial supplier of high-performance carbon/phenolic composites. We develop advanced materials and components designed for the most demanding thermal environments in rocket propulsion and atmospheric re-entry systems, including rocket nozzles, combustion chambers, thermal protection systems, propellant tanks, and other critical high-temperature structures. Carbon/phenolic composites combine exceptional thermal resistance, low density, and outstanding structural integrity, enabling significant weight reduction while maintaining performance under extreme operating conditions. These properties translate directly into increased payload capacity, improved mission efficiency, and lower launch costs. Today, Europe lacks an independent commercial supplier of high-performance carbon/phenolic composites. Existing capabilities are largely confined to aerospace manufacturers producing these materials exclusively for their own programmes. 

Our goal is to close this gap by providing both raw composite materials and flight-ready components to the rapidly growing European ecosystem of launch vehicle, propulsion, and re-entry system developers, giving them reliable access to a critical technology that is currently unavailable on the commercial market.
