Boston Engineering to Incubate UUV Technology


Boston Engineering's Advanced Systems Group (ASG) will incubate projects emphasizing maritime activities, such as its ground-breaking technology with unmanned underwater vehicles (UUVs). The site is adjacent to South Watuppa Pond and very close to the ocean, making it ideal for conducting UUV tests. "This move is in direct response to the progress made with our SBIR-funded UUV technologies," stated Mark Smithers, Vice President and Chief Technology Officer for Boston Engineering.

Hydroid asked to repair and upgrade Navy's fleet of MK 18


U.S. Navy officials are asking Hydroid Inc. in Pocasset, Mass., to repair and upgrade the Navy's fleet of MK 18 Kingfish unmanned underwater vehicles (UUVs), as well as to help train Navy personnel to use the unmanned submersibles.


Officials of the Naval Surface Warfare Center (NSWC) Indian Head Explosive Ordnance Disposal Technology Division in Indian Head, Md., are awarding Hydroid a $26.2 million contract to handle the UUV work. The Navy's MK 18 UUV is a variant of the Hydroid REMUS 600, which Hydroid developed originally developed through funding from the Office of Naval Research (ONR) in Arlington, Va., to support the Navy's UUVs with extended endurance, increased payload capacity, and greater operating depth.

Iranian Navy to Build Unmanned Submarines




Iran plans to build unmanned submarines. "This issue is on our agenda like other issues and cases," Navy Commander Rear Admiral Habibollah Sayyari told FNA when asked if the Iranian Navy has plans to build unmanned submarines and other types of Unmanned Underwater VehiclesAbout the reasons he didn’t provide any further details on the project, but it is known the Iranian Navy has been conducting anti-piracy patrols in the Gulf of Aden since November 2008, when Somali raiders hijacked the Iranian-chartered cargo ship, MV Delight, off the coast of Yemen.

According to UN Security Council resolutions, different countries can send their warships to the Gulf of Aden and coastal waters of Somalia against the pirates and even with prior notice to Somali government enter the territorial waters of that country in pursuit of Somali sea pirates. The Gulf of Aden - which links the Indian Ocean with the Suez Canal and the Mediterranean Sea - is an important energy corridor, particularly because Persian Gulf oil is shipped to the West via the Suez Canal.

PLUS System Completes Initial in-Water Testing

The PLUS (Persistent Littoral Undersea Surveillancesystem consists of an undersea network of "sea gliders" and long-endurance Unmanned Undersea Vehicles (UUVs).

The UUVs perform as autonomous vessels with long underwater dwell times that carry highly capable sensors. The sea gliders are smaller autonomous vessels that collect the UUV data, and return to the surface to transmit that data to a shore-based collection and processing station.

The PLUS system is designed to easily deploy from any ship with a winch and crane and sufficient storage capacity. The testing conducted at the Naval Undersea Warfare Center (NUWC) in Newport, R.I., Sept. 23 - 27, involved three UUVs and two sea gliders. Preliminary analyses of the results indicate that overall test objectives were achieved, and the PLUS system performed as expected.

Members of the Submarine Development Squadron Five UUV Detachment (DEVRON Five UUV Det) and LCS Squadron Anti-Submarine Warfare (LCSRON ASW) Mission Package Detachment One participated in this effort, helped set up the mission scenarios and assisted in the conduct of the tests. In turn, this exercise provided valuable training for the Navy operators who will be responsible for the PLUS system operations and maintenance. Testing will continue on the system until early 2015, when the Navy plans to deploy the PLUS system for overseas operational evaluation.

UUVs to stalk hostile submarines


Two high-profile events from the past three years have served to highlight the growing importance of the Unmanned Underwater Vehicle (UUV) in naval operations.


The first incident saw the Royal Navy minehunter HMS Brocklesby, operating off Libya in May 2011 as part of the NATO mission to enforce UN Security Council resolutions, deploy a SeaFox UUV to destroy a buoyant mine laid by pro-Gaddafi forces outside Misrata harbour. Subsequently, in August 2012, the US Navy sent dozens of SeaFox UUVs to the Persian Gulf after the Iranian government threatened to use its arsenal of Soviet-era mines to blockade the Strait of Hormuz, a move that would have effectively shut down a major proportion of the world's oil supplies.

Naval hydrographic and oceanographic units are using UUVs equipped with a wide array of sensors to chart the seabed and/or determine the characteristics of a given body of water, providing essential data for planning submarine and amphibious operations. Unmanned submersibles are also employed on search-and-rescue and intelligence, surveillance and reconnaissance missions. Meanwhile, trials have commenced in the US that will result in the introduction of a new class of deep-diving UUV designed to stalk hostile submarines.

Bluefin and NRL complete long-endurance UUV mission


Bluefin Robotics, in support of the Naval Research Laboratory (NRL), has successfully completed a long-endurance UUV mission from Boston to New York totaling over 100 hours with NRL’s Reliant “Heavyweight” UUV.

The multi-day mission exercised UUV autonomy methods and demonstrated the capability of a high capacity energy configuration. Further, the endurance test was designed to push the boundaries of traditional UUVs with the objective to uncover the challenges and requirements for significantly extending UUV endurance for new applications.


The exercise is part of a series to support NRL’s research in UUV-based technology for the US Navy. NRL Reliant Vehicle on DeckReliant, is an advanced version of the Bluefin-21 vehicle and, when equipped with a Low Frequency Broadband (LFBB) sonar payload, is the prototype SMCM UUV Knifefish system for the US Navy. The vehicle navigates using a fiber-optic gyro-based INS along with supplemental data from a GPS and a Doppler Velocity Log (DVL) to enable precise navigation underwater for long endurance missions.

Reliant utilizes Bluefin’s modular vehicle design that enabled the team to easily remove the payload section and add additional energy sections increasing the system’s energy capacity to nearly 40 kWh of power. Configuration took place over only a few days at Bluefin’s headquarters in Quincy, Massachusetts. The team mobilized the vehicle on the Boston Harbor Cruise’s, M/V Matthew J. Hughes, and deployed it outside Boston Harbor. To optimize for endurance and range, the vehicle traveled at an average speed of 2.5 knots at 10 meters water depth, resurfacing every 20 kilometers for navigation updates over GPS.

Team members on M/V Matthew J. Hughes and onshore were able to receive vehicle status information over Iridium satellite system. While the support vessel was available, it did not provide navigational updates to the UUV, leaving the system to travel completely autonomously. After 109 hours of operation and transiting over 500 kilometers through strong currents, the system successfully reached its end point in New York Harbor with 10% of its battery life remaining. The overall effort was funded by the Office of Naval Research.

New UUV Mothership Hits the Fleet: The Coastal Command Boat


The U.S. Navy recently introduced the new 65-foot Coastal Command Boat (65PB1101, or CCB) into the fleet.


Among other maritime security missions, the CCB will test new concepts in employing unmanned underwater vehicles. The boat has been configured to operate the MK 18 Mod 2 Kingfish UUV for mine counter-measures operations. 

Two of the 800-pound, 12-inch diameter UUVs sit in cradles on the stern of the CCB and are launched with the boat’s hydraulic crane.  The Navy is considering deploying the CCB to the Middle East for operational testing sometime in the next year.  Operating up to day-long missions from a shore base or even the well deck of a larger amphibious mothership, the CCB and MK VI PBs will deploy multiple mine-hunting UUVs

The Navy has also tested the man-portable SeaFox mine neutralizer from rigid-hull inflatable boats (RHIBs).  If equipped with SeaFox, the CCB and MK VI could not only find, but clear, detected mines, a capability that today is conducted with much larger dedicated mine countermeasures ships.

USN Signs Hydroid Contract for Mine-Countermeasures UUVs


In October 2013, Kongsberg Defence subsidiary Hydroid, Inc., of Pocasset, MA received a maximum $36.5 million, 5-year, sole-source award for its unmanned underwater vehicles (UUVs) from the US Navy’s Naval Explosive Ordnance Disposal Technology Division in Indian Head, MD. They’ll be buying 2 types of UUVs: MK18 MOD1 Swordfish and MK18 MOD 2 KingfishBoth of these UUVs are currently contractor-operated, but the US Navy does intend to begin operating them itself by 2015. They probably could be loaded onto a Littoral Combat Ship as an interim measure, ahead of the planned 2017 in-service date for Bluefin RoboticsKnifefish SMCM mine-countermeasures UUV.

Israel Defense Forces to Develop Drone Submarines


The department within Israel’s Ministry of Defense, tasked with developing next generation weaponry, MAFAT, is working on developing unmanned underwater vehicles, the market for which could exceed $2 billion by 2020, Israel’s Globes business daily reported, citing MAFAT aeronautics director Dr. Yuval Cohen.

UUVs include ROVs - remotely operated underwater vehicles that are operated by remote control – and AUVs - autonomous underwater vehicles which are  fully robotic, submarine drones, where Israel’s ingenuity could add the most value. The biggest market would be in mine-sweeping, Dr. Cohen told Globes. “The current response to this threat is slow and very expensive sweeps. Development of an automated unmanned submarine for efficient mine-sweeping, without risking human lives, should be very worthwhile and there is a good global market,” he said.

Bluefin Robotics Adds L-3 Klein UUV-3500 Side Scan Sonar to its Vehicle Payload Offerings


Bluefin Robotics, a leading provider of Unmanned Underwater Vehicles (UUVs), announced that the company has added the L-3 Klein UUV-3500 Side Scan Sonar to its growing list of vehicle payload offerings.


The L-3 Klein UUV-3500 sonar is one of several next-generation, compact digital sensors available on Bluefin vehicles that provide both side scan sonar and interferometric bathymetry data particularly suited for mine countermeasures applications.

In 2012, the Ocean Technology Lab at the University of Victoria first integrated the sonar on a Bluefin-12 by utilizing Bluefin’s standard payload interface. Their team conducted successful demonstrations and survey work in Canadian Arctic and provided valuable feedback to both Bluefin and L-3 Klein regarding system level performance.

UUV vs UAV: La ventaja militar asimétrica



En comparación con el desarrollo tecnológico de los UAVs, el desarrollo tecnológico de los UUVs está todavía en fase de crecimiento.
 
Ahora bien, los responsables militares de la OTAN están impulsando con fuerza el desarrollo de nuevos UUVs, conscientes de que éstos cuentan con la capacidad de ofrecer muchas ventajas frente a los UAVs. Vamos a ver algunas de sus ventajas, y algunos de sus inconvenientes.
 
Ventajas
  • Los UUVs, por su propia naturaleza de vehículos subacuáticos, son extremadamente difíciles de detectar: Considerando lo difícil que resulta detectar un submarino de gran tamaño, resulta fácil imaginar lo extremadamente difícil que puede resultar la detección de un submarino cientos de veces más pequeño. Gracias a ello, permiten monitorizar posibles amenazas (minas, submarinos, etc.) indetectables por los UAVs.
  • Existen actualmente varias tecnologías de aprovisionamiento energético que podrían permitir a los UUVs operar casi indefinidamente, y esto es algo en lo que aventajan en mucho a los UAVs:  Energía solar, regeneración por oleaje, recarga térmica, recarga iónica, etc. son algunos de los métodos que ofrecen la posibilidad de obtener una autonomía extremadamente elevada.
  • Los posibles usos de los UUVs en el terreno militar naval exceden con mucho las capacidades de los UAVs:  Imaginemos la posibilidad de colocar pequeñas cargas explosivas junto al casco de un barco amarrado en su propia base, o colocar un pequeño UUV permanentemente junto al casco de un barco o de un submarino enemigos, a fin de efectuar un seguimiento constante de los mismos. Aunque son dos ejemplos al azar, creo que bastan para hacerse una idea.
Inconvenientes
  • Por supuesto, existen problemas asociados. La comunicación subacuatica es uno de ellos. De nada sirve recopilar datos... si éstos no pueden transmitirse.
  • Por si lo anterior fuera poco, el control remoto subacuatico de un UUV situado a larga distancia del centro de mando resulta aún más dificil, cuando no imposible. Frente a este problema, parece claro que habrán de encontrarse soluciones basadas en sistemas autónomos, al igual que se ha hecho con los UAVs. No es difícil: Es sólo cuestión de tiempo. Pero indudablemente es un inconveniente que los UAVs no tienen.

Here’s How Darpa’s Robot Ship Will Hunt Silent Subs

 
Submariners like to say there are two kinds of ships: subs and targets. The Pentagon’s futurists want to turn that aphorism on its head, and develop a new kind of surface ship that can turn a sub into a target. Naturally, the sub-hunter won’t have a human on board. Here’s how it’s going to work. (Read more)
