Dutch NGO Pax for Peace on 23 August published a report which says that the number of military drone producers and exporters has grown significantly in recent years. While the US, Israel and China are dominating the high-tech segment of the global drone market, emerging drone technology producers are focusing on gaining a substantial share of the middle- and small-range sector of the market for military drones. The survey conducted for the report indicates that there are 21 countries producing at least 60 different types of drones within this segment, serving a global market estimated to be worth $20 billion.
