PT DHARMA DWITUNGGAL UTAMA’s parent company, i.e. PT DWI TUNGGAL JAYA, was established in 1965 and engaged in the supply of stationery, survey, and laboratory equipment to government institutions. A few years later a new business line was added: Sales, Installation, and Maintenance of Electronic Radio Communication and Navigation Equipment for Land and Marine use, while the stationary and laboratory equipment business was phased out.
