NAVAL DRONES

Multi-rotors have been well-received by hobbyists and even garnered some interest from the U.S. Navy.  But up until now, these lightweight UAVs haven't mixed very well with water.  The guys at Aquacopters have changed this with a water-proofed and ruggedized simple quad-frame.  The ability to capture video above, on, and under the surface of the water with a single small drone creates an interesting range of options for hobby, scientific, commercial, or military use.

Although the Polish Navy operates a range of remotely operated vehicles today, there is no yet publicly known autonomous vehicle in operation.   The situation is quickly changing, though.  Three AUV systems planned for mine-hunting use on future patrol ships were mentioned in the Navy's last modernization plan. Additionally, General Skrzypczak, responsible for modernization programs in the Ministry of Defense, recently discussed MoD interest in Unmanned Surface Vessels for port protection and surveillance. These craft are expected to have some limited offensive capability. Not surprisingly, during a visit at this year's Euronaval convention, the Israeli company Rafael introduced the Polish delegation to its latest up-armed version of Protector .  Later it was reported that after the exhibition, an agreement for potential technology transfer between companies (not mentioned by name) was signed. It is an impo...

Experimentation with large numbers of low cost quadrotors operating in swarms has produced some interesting results, including potential for future military applications.  Now some researchers in Germany are working to transition these concepts to the underwater realm, building autonomous underwater vehicles (AUVs) that behave like fish in a school.  A team at the University of Luebeck's Institute of Computer Engineering has developed an affordable AUV designed for environmental surveys called MONitoring System and Underwater Navigation Robot (MONSUN ) II. MONSUN II is a 4 kilogram AUV equipped with a series of vertical and horizontal thrusters to maneuver and maintain orientation.  The vehicle maintains its position relative to other AUVs in the school using infrared sensors and a nose camera with a form of computer image recognition called "blob detection."  The swarming technology demonstrat...

PALMDALE, Calif. (Aug. 8, 2012) Chief of Naval Operations (CNO) Adm. Jonathan Greenert observes a fly-by demonstration of a Predator C Avenger unmanned aerial vehicle. (U.S. Navy photo by Mass Communication Specialist 1st Class Peter D. Lawlor/Released) In a nod to maritime tradition, the new Chief of Naval Operations set forth a " Navigation Plan " with budgetary priorities and a route to achieve the vision he set in the " Sailing Directions " for 2013-2017.  Admiral Greenert's prioritization of unmanned systems for the U.S. fleet in these documents is anything but archaic.  Seven of the CNO's 34 budget focus areas directly address unmanned systems, including: "Increase near-term mine warfare capability with Quickstrike mines; the Seafox Mine Neutralization System ; upgraded MCM-1 class ship sonar, hull, and engineering upgrades; and Unmanned Underwater Vehicles (UUV) for shallow and bottom mine detection. Improve near-term cap...

The U.S. Navy's recent testing of a Protector unmanned surface vessel with the Precision Engagement Module (PEM) weapons system warrants deeper analysis than provided by news reporting.  The project is sponsored by the Chief of Naval Operation's Expeditionary Warfare Division (N95) and the Naval Sea Systems Command's Naval Special Warfare Program Office.  To understand the ramifications of this testing, it's worthwhile to elaborate a bit on the components that make up the PEM: Protector 11 Meter Variant unveiled at Euronaval 2012 (Photo Courtesy of Shepherd Media ) Protector USV - The U.S. Navy's Protector is a joint development between Israel's Rafael, BAE Systems, and Lockeed Martin.  Originally conceived as a platform for force protection and port security, the 11 meter vessel's new armament opens up a range of possibilities for future employment (discussed below).  Much like a UAV, the Protec...

As long as physical limitations constrain the range and endurance of unmanned air, surface, and sub-surface vehicles, they will need to operate in conjunction with larger platforms.  These motherships serve a wide variety of functions besides simply transporting, launching, and recovering unmanned vehicles.  They maintain and repair the drones, recharge or refuel their propulsion sytems, and they enable data collected from unmanned sensors to be downloaded, analyzed, and disseminated beyond the line-of-sight.  Characterizing the evolution of these unmanned vehicle motherships can help extrapolate how they might be used in the future. Generation I - Ad hoc platforms: This category includes legacy naval vessels ranging in size from patrol craft (US SOCOM's MK V at right, with ScanEagle) to large amphibious ships, and likely some day, aircraft carriers.  Minesweeping and hunting vessels have carried remotely opera...
