The significant excess of demand over supply initiates the speed increasing of world market of unmanned multi-purposes complexes (MPC) last years. Except space unmanned systems and unmanned flying systems of aircraft type [1], also exists helicopter and balloon (zeppelin) aviation MPC, land-on and underground MPC, also marine and submarine MPC. According with the proposed classification shortly define and determine the modern MPC applications. The article is devoted to the helicopter, balloon (zeppelin), land-on and underground, marine and submarine MPC, designed by Russian and foreign scientific and industrial organizations and enterprises, including Moscow Mile helicopter plant, "Schiebel", "Unmanned systems", "Raytheon", "IRKUT', "RosAeroSystems", "SEW Eurodrive", "iRobot", "Black-I Robotics", "QuinetiQ", "KEMZ", "SPB PA" companies, "Central scientific researching and experience construction institute of robot-technique and technical cybernetics", "Central scientific research institute "Hydrodevice"", "SEA-EAGLE", "SeeBotix", "Augusta Systems", "TOYO", "EMT", Bauman State University, Massachusetts technological institute, Harvard university and DARPA. This MPC may be used in different spheres, such as oil and gas monitoring, fire-protection systems, industrial safety, ecological equipment, bogy guard and other civil applications. The comparing of air, land-on, underground, marine and submarine MPC by financial and economical parameters supports the realization of regional investment projects. Much attention is paid for industrial and ecological monitoring with protection of communication channels based on computer steganographic technologies, which are protected by author's Russian patent for invention.
