Czech-backed PBS Aerospace has partnered with Zone 5 Technologies under a significant subcontract supporting American military propulsion requirements. The collaboration will advance US-based manufacturing of small turbojet engines optimized for unmanned aerial and strike systems. Featuring compact dimensions and high thrust output, the TJ40 and TJ80 engines enable rapid integration into modern autonomous platforms. The partnership builds on the company’s recent expansion into the United States, aimed at strengthening domestic production resilience and supporting growing demand for defense propulsion technologies.
