The global unmanned aerial vehicle payload market, valued at about $43.7 billion at the end of 2012, will increase to $68.6 billion by 2022, according to an estimate in a report by Strategic Defense Alliance. Market demand is anticipated to be driven by increased UAV procurement by several countries and continuous requirement formulations in areas such as persistent surveillance, suppression/destruction of enemy air defense, communications relays and combat search and rescue. Another factor expected to drive the market is the increasing incorporation of UAVs in civilian applications. (Source: Space War, 01/07/13)
