Newport Beach-based Resdel Industries agreed to sell its Arcadia-based defense subsidiary, Resdel Engineering, to a British telecommunications concern for more than $5.7 million. Dowty Group PLC purchased most of the assets of Resdel Engineering, whose principal business is producing anti-submarine warfare equipment. The Arcadia operation, which has been unprofitable, employs about 200 people, said Jack B. Spencer, Resdel’s chief financial officer.
