NAVAL DRONES

The Australian government recently approved the acquisition of a fleet of US Navy  Triton   surveillance drones  to patrol our oceans. Australia has mostly used Israeli drones to date, such as the  Heron s in Afghanistan. So as we dip our toes into the American UAV market, it’s worth taking note of a recent development that might be threatening US primacy in this area. While the  Predator  and  Reaper  laid the groundwork for the use of armed drones in warfare, a question remains about the survivability of the technology against modern air defences. Developing a stealthy long-range drone with a decent weapons payload that could go beyond missions in Yemen and Pakistan appeared to be the next order of business for the US, especially in the future Asia-Pacific theatre. Projects like the demonstrator  X-47B  unmanned combat air vehicle (UCAV) have shown promise in achieving those missions. But for now the US Navy has decided to go for a...

If airborne search assets succeed in finding the wreckage of Malaysian Airlines Flight #370, what happens US Navy Towed Pinger Locator. next?  Generally, the key to determining the cause of air plane crashes at sea is dependent upon the recovery of the data recorder, or "black box" as it is generally known.  A black box has an acoustic "pinger" which is activated upon hitting the water and transmits a signal, sometimes for up to 30 days.  Once crash debris is spotted on the ocean, salvage experts will use predictive modeling software to determine an approximate location of where the aircraft actually went down.  Even small ocean currents of a knot or two can push floating debris hundreds of miles away from the original crash site over a two week period. At that point, if it is determined that one or more of the regional navies involved will search for the black box, a towed pinger locator will be deployed from a ship, a...

Let’s face facts: it appears the U.S. Navy is incapable of building surface combatants, even small ones, for less than about a billion dollars apiece.  Consequently, it is likely the fleet will continue to shrink for the foreseeable future.  Yet it appears that the global demand for surface ship presence remains high for both peacetime operations and as an on-call force for contingency response.  So how can the Navy continue to meet worldwide operational commitments given fewer ships?  The key to maximizing the effectiveness of a declining surface force lies in combining suitable motherships with the latest unmanned warfighting technology.   Unmanned naval systems are rapidly proliferating internationally because they are increasingly capable and cheaper than manned alternatives for certain missions.  To date, sea-based unmanned systems have primarily conducted intelligence, surveillance, reconnaissance and mine countermeasures operations.  But w...

In most ‘drone’ conferences, there comes an awkward moment when a panelist realizes that the category ‘drone’ has very little to do with the question that they’re asking. To quote the Renaissance philosopher Inigo Montoya, “I don’t think that word means what you think it means.” In order to improve the remote aviation technology discussion, we need to be clear what we’re actually talking about.  What we should be talking about is ‘remote aviation technology,’ which is simply a fusion of the air and cyber domains through the ubiquitous technologies of datalinks, autopilots, and performance airframes. The fundamental tension is not between risk and responsibility, the two things over which the pop-sci-strat ‘drone’ debate obsesses, but between latency and performance. To the risk point, a military has a moral obligation to reduce risk to its warfighters, so reducing risk through tech is not new; to the responsibility point, professionalism and integrity are the roots for the w...

Bio-inspired robotics research continues to pave the way for future military applications.  In 2012, researchers proved that Autonomous Underwater Vehicles (AUVs), could perform simple swarming functions.   This blog discussed that technology and its implications for naval use in a post here . CoCoRo   (Collective Cognitive Robots) is a consortium of European universities led by the Artificial Life AL at the Department of Zoology at the Karl-Franzens-University Graz engaged in developing autonomous swarms of underwater vehicles to monitor, search, and explore the underwater realm.   The "Jeff" AUV production line. As seen in the above video, their AUVs demonstrate novel underwater communications methods and simple swarming behavior.  CoCoRo is currently building 20 copies of its newer AUV, "Jeff," which can maneuver rapidly underwater and dock to a floating surface station for battery recharging and da...

In a piece in mid-December, our partner site NavalDrones detailed  the U.S. Navy’s solicitation for an unmanned aerial vehicle (UAV) that incorporates Magnetic Anomaly Detector (MAD) sensors. As the article notes, this capability is useful for finding submarines as it “detects changes in the earth’s magnetic field caused by a large metal object” such as yon u-boat. What is perhaps most interesting about the solicitation is that it calls for the UAVs to be expendable and launched from a P-8A Poseidon. The concept of aerial motherhips is by no means new – one only need look back to the glory days of zepplins with biplane detachments, or to the helicarrier in the recent movie The Avengers  to get a sense of the breadth of idea. And the solicitation for the Poseidon doesn’t mark the first go at aircraft-launched UAVs: In 2009, an expendable sonobuoy tube-launched UAV called Coyote was tested out a NOAA’s WP-3D Orion under an Office o...

What was the most significant development in unmanned naval systems for 2013?  Blog readers weighed in on this question and more during our survey. Winning by a landslide, with 71% of the responses, was the successful carrier catapult shots and "traps" (arrested landings) of Northrop Grumman's X-47B. ALANTIC OCEAN (Nov. 9, 2013) The experimental X-47B Unmanned Combat Air System Demonstrator (UCAS-D) conducts an arrested landing aboard the aircraft carrier USS Theodore Roosevelt (CVN 71). Theodore Roosevelt is the third carrier to test the tailless, unmanned autonomous air craft's ability to integrate with carrier environment. (US Navy photo By Mass Communication Specialist Seaman Anthony N. Hilkowski/Released) In a distant second, with 19% of the vote, was the proliferation of sea-going rotary wing UAVs. The number of helicopter drones, like this Spanish Skeldar, grew throughout the world's fleets in 2013. Related to #1, the U.S. Navy's ev...
