General Dynamics has acquired the defense operations of Gayston Corporation, a privately held company that supplies precision metal components used in several munitions programs. Gayston's defense manufactures rocket motor tubes for the U.S. Army's Hydra-70 air-to-ground rocket program. It also provides liners and cartridges for 40mm ammunition rounds and components for 60-120mm mortar rounds to a variety of customers. The defense operations of Gayston will become part of Charlotte, N.C.-based General Dynamics Armament and Technical Products. "The acquisition of Gayston's defense operations expands our critical manufacturing capability to cost-efficiently produce high-precision parts in large quantities," said Michael J. Mulligan, president of General Dynamics Armament and Technical Products. "The acquisition also provides us with more opportunities to participate in high-performance weapon system programs".
