Canaris continued to be used because of his contacts in Spanish politics and industry. The proposed ventures included a joint air-traffic monopoly, an anti-aircraft system for the Spanish military, and sea-mine manufacture. His personal connections therefore linked political and industrial work to arms projects. Officials also considered using him as a quasi-official naval attaché in Spain, an unusual proposal because Germany had no military attachés overseas.
