PBS Aerospace, a member of the PBS GROUP and a leading manufacturer of precision-made turbojet engines for the modern battlefield, has been awarded a $3 million prime contract with the U.S. Air Force through an Other Transaction Authority (OTA) mechanism. The contract supports efforts to provide reliable propulsion systems that meet the affordability targets and production demands of the Family of Affordable Mass Munitions (FAMM) and other active U.S. Air Force programs. This award represents PBS Aerospace’s first publicly disclosed prime contract with the U.S. government, positioning the company as a direct industrial partner to the U.S. Air Force rather than simply a component provider within a larger supply chain.
As a prime contractor, PBS Aerospace holds contractual accountability for delivery and performance at the program level. The company’s small turbojet engines power unmanned, attritable systems where scalability, affordability, and reliability are critical operational requirements. PBS Aerospace’s Roswell, Georgia facility is actively scaling production to fulfill this contract and existing commitments, reflecting a real and growing contribution to the U.S. defense industrial base. The Roswell facility was established in under a year, demonstrating the company’s ability to move at the speed required by today’s defense environment.
Petr Kádner, CEO of PBS GROUP, stated: “PBS GROUP’s investment in U.S. defense manufacturing is what made this contract possible. Our focus on scalable, affordable propulsion positions PBS Aerospace to support the growing operational requirements of American and allied forces.”
William Didden, Owner of PBS GROUP, added: “This prime contract is a direct result of our team’s commitment to American defense manufacturing. It signals our intent to deepen PBS Aerospace’s role as a trusted, scalable partner within the U.S. defense industrial base.”
Erin Durham, CEO of PBS Aerospace, said: “This contract is an important milestone for PBS Aerospace and a strong validation of the role we are building in the U.S. defense industrial base. It reflects the confidence the U.S. Air Force has placed in our team, our propulsion technology, and our ability to scale production in the United States to support mission-critical unmanned systems. We are building more than engines in Roswell—we are building responsive American manufacturing capacity for the Air Force’s critical needs.”
The contract reinforces PBS Aerospace’s strategic role within the U.S. defense industrial base at a time when the Department of Defense is prioritizing domestic production capacity and speed-to-scale for unmanned systems.
