Unmanned aerial vehicles (UAVs) are not new to Southeast Asia. Thailand acquired an unmanned reconnaissance capability already in 2001, when the Royal Thai Army purchased four IAI Searcher Mk. II reconnaissance UAVs from Israel. Several more drone acquisitions would follow (mainly from Israel) in the following decades, ultimately resulting in the expansive unmanned arsenal in service with the Royal Thai Army, Air Force and Navy today. This meanwhile also includes an increasing number of locally-designed UAVs or types produced under license from China.
