Roke, legally Roke Manor Research Ltd, is a British company based at Roke Manor near Romsey, Hampshire, which conducts research and development in the fields of communications, networks, electronic sensors, artificial intelligence, machine learning, data science, Military decision support consultancy and operational analysis, information assurance, and human science. In addition to supporting its parent Chemring, Roke undertakes contract research and development, and product development work for both public and private sector customers.
