SAIC Reveals New Details on ASW Drone

By -
Science Applications International Corporation (SAIC) has released an updated promotional video on the Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV), a DARPA Tactical Technology Office project to develop an autonomous surface vehicle. ACTUV is specifically designed to conduct long duration autonomous tracking missions against diesel submarines.
The video reveals some interesting new details on the awkwardly-acronymed vessel. The computer-generated vignette shows ACTUV working in conjunction with other platforms to track and prosecute submarines using onboard sensors. These include a mid-frequency active/passive sonar mounted in a pod under the vessel's keel, two high frequency active sonars for localization, and a total-field magnetometer array along the ACTUV's hull for close-in tracking. A very high frequency sonar will then use acoustic imaging to classify the sub. Also interesting are the other possible missions ACTUV could conduct which include:
  • Intelligence, Surveillance, and Reconaissance
  • Acting as a Surveillance Towed Array Sensor System (SURTASS) surrogate, a mission currently conducted by manned platforms.
  • SOF Over-watch and support
  • Acting as a mothership for UUVs and AUVs
  • Communications relay for networked undersea sensors
  • Littoral logistics and resupply
If successful, ACTUV will be a critical demonstration of the value of unmanned surface vessels for long duration missions.

CHINA SEIZES U.S. NAVY UNDERWATER DRONE

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...

CATCH OF THE DAY: REFLECTIONS ON THE CHINESE SEIZURE OF A U.S. OCEAN GLIDER

By -
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...
