About the company
Physics Applications Inc., doing business as PAI, manufactures precision ballistic testing equipment, gun barrels, breech systems, launch tubes, and specialized physics-based components for the Department of Defense, serving exclusively as a prime contractor on purchase orders and blanket purchase agreement calls with no subcontract footprint. Based in Dayton, Ohio (with performance at Sugar Creek Township), PAI is a for-profit Subchapter S Corporation competing across both set-aside (Total Small Business) and full-and-open procurements, with the majority of recent awards on non-set-aside sole-source basis.
PAI's customer concentration anchors heavily in Navy and Army research and development commands. The top five customer agencies by award count account for 65% of recent awards: the Department of the Navy Naval Sea Systems Command leads with 46 awards valued at $1.4 million combined potential, followed by the Department of the Army Research Development and Engineering Command (DEVCOM) with 12 awards carrying $1.6 million in potential value, and the Department of the Navy Naval Air Systems Command with 12 awards valued at $283 thousand. By dollar value, Army DEVCOM ($1.6 million across twelve awards), Navy NAVSEA ($1.4 million across forty-six awards), and the Air Force ($1.2 million across full-and-open and test-center procurements) dominate the top three. PAI's award portfolio spans 20 distinct customer agencies, with procurement concentrated in NAICS categories for measuring and controlling device manufacturing (53 awards), small arms and ordnance manufacturing (16 awards), and PSC codes for guns over 30mm to 75mm (27 awards).
Recent representative work includes a $1.25 million firm-fixed-price purchase order from the Air Force (July 2024) for design, manufacture, and delivery of a two-stage light gas gun launcher system at Arnold Engineering Development Complex in Tullahoma, Tennessee; a $261.2 thousand full-and-open purchase order from Army DEVCOM (September 2024) to upgrade a ballistic testing assembly at Aberdeen Proving Ground with gas breech and control systems; and a $248.9 thousand sole-source purchase order from Navy NAVSEA (February 2025) for a tank assembly for a 40mm single-stage gas gun system at Naval Surface Warfare Center Dahlgren Division. PAI holds a single-award $440 thousand blanket purchase agreement with the Army Corps of Engineers Engineer Research and Development Center (established May 2021, extending through May 2026) for powder and gas gun components, consumables, and technical support at the Vicksburg, Mississippi facility, with seven BPA calls issued under it valued at $127 thousand combined. Award activity has declined from six contracts in 2022 to one in 2026 year-to-date, with a combined potential value of $8.5 million across 133 prime awards and $10.1 million in total obligated dollars. PAI competes across both Total Small Business set-asides and unrestricted solicitations, with sole-source justification recurrent across its defense portfolio due to original design and fabrication capabilities and incumbent operational familiarity at customer facilities.
