PBS Aerospace, a member of PBS GROUP, the leading manufacturer of precision-made turbojet engines purpose-built for the modern battlefield, today announced it has signed a significant subcontract agreement with Zone 5 Technologies, Inc.. The agreement is valued at several tens of millions of dollars.
The agreement follows the September 2025 opening of PBS Aerospace’s U.S. headquarters in Roswell, Georgia, backed by a $20 million investment by PBS GROUP owner William Didden to scale U.S. production of precision-made turbojet engines.
“This agreement demonstrates that PBS Aerospace has the operational maturity and capacity to serve as a long-term industrial contributor to U.S. defense priorities,” said PBS GROUP Owner William Didden.
The multi-year subcontract supports PBS Aerospace’s U.S. manufacturing operations for precision-made turbojet engines serving defense applications.
“This agreement represents a significant commitment to expanding our U.S. defense manufacturing capabilities,” said Erin Durham, CEO of PBS Aerospace. “Our Georgia facility is operational and scaling production to meet the demands of customers who require reliable, high-performance propulsion systems.”
PBS Aerospace manufactures the PBS TJ40 turbojet engines with a thrust of approximately 100 lbs and the PBS TJ80 with a maximum thrust of 200 lbs, designed for rapid deployment and integration into missile and unmanned systems, where size, weight and performance represent key mission-critical requirements.
“PBS Group’s investment in U.S. manufacturing infrastructure reflects our commitment to supporting national security priorities through proximity to customers, agile production capabilities and adherence to U.S. defense standards,” said Petr Kadner, CEO of PBS GROUP.
