NAVAL DRONES

By Heiko Borchert On 15 December 2016, China seized an  Ocean Glider , an unmanned underwater vehicle (UUV), used by the U.S. Navy to conduct oceanographic tasks in international waters about 50-100 nautical miles  northwest of the Subic Bay port  on the Philippines. Available information suggests that the glider had been deployed from USNS  Bowditch  and was captured by Chinese sailors that came alongside the glider and grabbed it “despite the radioed protest from the  Bowditch  that it was U.S. property in international waters,” as the  Guardian  reported. The U.S. has “ called upon China  to return the UUV immediately.” On 17 December 2016 a  spokesman of the Chinese Defense Ministry  said China would return the UUV to the “United States in an appropriate manner.” Initial legal assessments by U.S. scholars like  James Kraska and Paul Pedrozo  suggest the capture is violating the law of the sea, as the unmanne...

On December 15th 2016, the Chinese Navy seized an American unmanned underwater vehicle (UUV) operating in international waters off the Western coast of the Philippines. The  USNS Bowditch ,  an unarmed T-AGS class hydro-graphic survey ship, was being shadowed by a People’s Liberation Army-Navy (PLAN) salvage vessel identified as a Dalang-III class (ASR-510). Graphic by: CIMSEC Member Louis MV The UUV had surfaced as part of a pre-programmed instruction, and sent  a radio signal marking it’s position for pick-up. As the Bowditch was preparing to recover the drone from the water, a small boat crew from the Dalang III raced in and plucked the unmanned vessel. The incident occurred approximately 50 nautical miles northwest of Subic, Luzon. While the exact type of drone is unknown, there have been several instances of U.S. Navy   Slocum Gliders   snagged in local fishermens’ nets or washed ashore on beaches in the Philippines. This type of drone is not weap...

The US Navy recently announced that it will make more use of submarine drones, contracting with marine technology developer Teledyne Benthos to re-purpose the Slocum Glider as an instrument used for military activity. The contract is worth $203.7M.   If you haven’t heard of it yet, here is what the Slocum Glider is: a 5 foot-long autonomous underwater vehicle capable of moving to specific locations and descending to depths of 4,000 feet. It is driven by variable buoyancy, and it can move both horizontally and vertically.   The Slocum Glider can be programmed to patrol for weeks at a time, collecting data on its environment, surfacing to transmit to shore while downloading new instructions at regular intervals. Compared to traditional methods, the drones have a relative small cost: the need for personnel and infrastructure is reduced to its minimum and the vehicle is able to work around the clock and around the calendar. It works very well: in November 2012, an auto...
