ROSWELL, GA / ACCESS Newswire / February 24, 2026 / PBS Aerospace, 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 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.
