General Dynamics acquired the defense operations of Gayston Corp., a privately held company that supplies precision metal components used in several munitions programs. Gayston's defense operations employ 187 people at a facility in Springboro, OH, which is optimized for aluminum impact extrusion manufacturing. Among its products, Gayston manufactures rocket motor tubes for the U.S. Army's Hydra-70 air-to-ground rocket program. It also provides liners and cartridges for 40-mm ammunition rounds and components for 60-120-mm mortar rounds to a variety of customers. The defense operations of Gayston will become part of Charlotte, NC-based General Dynamics Armament and Technical Products, a provider of high-performance weapon and armament systems, composite products, and heavy-duty off-road axle and suspension systems to the U.S. military, allied forces, and commercial customers.
