navycurrents US Navy Granted Funding for Ship Repairs The U.S. Navy will be able to keep shipyards open for maintenance as the $287 million needed for ship repairs will not be cut from the budget, reported The Virginian-Pilot. As the government deals with sequestration, the U.S. Navy was facing the possibility of the cancellation of maintenance contracts for 11 warships. The decrease in funding would have resulted in job loss for thousands of shipyard employees. Nine of the projects will be completed within the next few months as planned, and most scheduled maintenance will take place. Two ships are at risk of losing funding for repairs, but are not scheduled to be fxed until September. As President Barack Obama's administration decides how to allocate funds for the U.S. Department of Defense, the upkeep of ships will remain a priority, while projects on bases will be put on hold. If sequestration continues, $51 billion will be cut from the Pentagon next year. BAE to Provide Mine Detection for US Navy BAE Systems (Arlington, Virginia) has a $20 million contract to develop an advanced prototype system that detects mines and obstacles in nearshore waters for the U.S. Navy and Marine Corps. As part of the Coastal Battlefeld Reconnaissance and Analysis (COBRA) program, the laser-based, airborne system will provide 24-hour capabilities. FOLLOW SEA TECHNOLOGY ON.... BAE Systems' prototype uses light detection and ranging technology to determine the distance to an object or surface. Lidar is similar to radar, but uses laser pulses instead of radio waves. It has the ability to collect images at a high resolution through the sea surface, allowing small underwater objects to be detected. The prototype system incorporates a fast-scanning laser, 3D imaging camera and target recognition algorithms to locate and classify surface and underwater threats. General Dynamics Completes Design For UUV General Dynamics Advanced Information Systems (Fairfax, Virginia) has completed the design review for Knifefsh, the surface-mine countermeasure UUV. The General Dynamics team will now begin the development of the system hardware and software to integrate the approved design through the fabrication of three engineering development modules. Knifefsh is a part of the littoral combat ship mine countermeasure (MCM) mission package, which provides U.S. Navy commanders and sailors with mine-hunting capabilities. Knifefsh is the frst heavyweight-class MCM UUV that will help the U.S. Navy detect and classify mines resting on the seafoor, as well as buried mines in high-clutter environments and areas with potential for mine burial. Knifefsh also gathers environmental data to provide intelligence support for other mine warfare systems. L-3 Klein to Provide Sonar Systems For the Royal Canadian Navy L-3 Klein Associates Inc. (Salem, New Hampshire) has received $4.3 million from MacDonald, Dettwiler and Associates Ltd. of Canada to supply four S5900 side scan sonar systems and accessories for the Royal Canadian Navy's Route Survey System Life Extension (RSSLE) Program. The RSSLE Program will provide required updates for certain subsystems of Canada's Integrated Survey and Inspection System, operated in Kingston-class Maritime Coastal Defense Vessels (MCDVs). The S5900, together with other updates, will provide the Canadian Armed Forces with support through the end of the planned operational life of the MCDV feet, to at least 2025. The system will also provide seabed obstacle detection and a reduced risk of obstacle collision and tow-body grounding during operations. Royal Navy Visits Saab Seaeye 64 st / MAY 2013 The Royal Navy has visited Saab Seaeye Ltd. (Fareham, England) to view underwater vehicle technology designed for maritime defense. A delegation toured the facilities at Fareham, which have recently doubled in size since the opening of a second factory building. During the visit the delegation saw a demonstration of a Falcon ROV operating a ballista mine neutralization system. The Navy said it is looking for innovative mine disposal systems beyond those currently in service. It is interested in unmanned systems, including hybrid underwater vehicles. There is a growing demand from the Royal Navy for both AUVs and ROVs. The Navy's maritime capability is moving from London, England, to the Navy command headquarters at Portsmouth, England. n
