ONR Completes Successful Demo of New Lightweight JHSV Ramp
The U.S. Office of Naval Research (ONR) completed a successful demonstration of a new lightweight ramp intended for use on the Navyís joint high-speed vessel (JHSV). The advanced ramp would provide significant improvement over the JHSVís current ramp by allowing the loading or unloading of people and combat vehicles in rougher ocean conditions than are currently possible between a JHSV and another ship, pier or mobile landing platform.


Kraken Delivers AquaPix Sonar for Mine Countermeasures
Kraken (St. Johnís, Canada) successfully delivered the AquaPix Synthetic Aperture Sonar System to Defence Research and Development Canada for its Underwater Warfare Program, which focuses on unmanned systems for naval mine countermeasures. Synthetic aperture sonar provides significant improvements to along-track resolution through the coherent summing of sonar pings as the AUV follows a straight-line trajectory. The increased image resolution and quality can provide better input for automatic target recognition, battle space characterization and marine autonomy.

AquaPix provides seabed imagery with a constant along-track/across-track resolution better than 3 by 3 centimeters, with 500-meter swath. It simultaneously produces 3D bathymetric data with bin resolutions better than 10 by 10 centimeters.


MUOS Satellites Provide ICEX With Secure High-Data Connections
Mobile User Objective System (MUOS) satellites during the U.S. Navyís 2014 Ice Exercise (ICEX) provided nearly 150 hours of secure data connections. This was the first time military users could transfer large megabyte data files over stable satellite connections in the Arctic.

Working atop a floating ice camp above the Arctic Circle, a Lockheed Martin (Bethesda, Maryland) team provided satellite communications, allowing download of multiple files up to 20 megabytes. A steady stream of photos, maps and other large data were sent securely through the system, something not possible via legacy communication satellites.


Acentech to Develop Tech to Reduce Diver Helmet Noise
Acentech Inc. (Cambridge, Massachusetts) received final funding on a three-year, $706,000 project for the U.S. Naval Sea Systems Command to develop technologies that reduce noise experienced by divers in dive helmets.

Navy divers can develop hearing damage over their careers from underwater noise, which contributes to the $2.5 billion annual costs borne by the Veteransí Administration for treatment of hearing loss and tinnitus.


Brazil Navy Gets Two More AXYS 3-Meter Buoys
AXYS Technologies Inc. (Sidney, Canada) has shipped two 3-meter buoys for the Centro de Hidrografia da Marinha (CHM) of the Diretoria de Hidrografia e Navegacao (DHN) in Niterói, Brazil. The buoys will bring the total number of 3-meter buoys owned by Brazilís Navy to 10.

The buoys will be deployed offshore to provide complete coverage of Brazilís coastline. They will be integrated using AXYSís WatchMan500 controller and various sensors to measure directional waves, currents, wind speed and direction, air pressure, air temperature, relative humidity and solar radiation in real time.


Defense Department Looks to High-School Students for Future
The Department of Defense sponsored high-school students in Washington, D.C., for the 52nd National Junior Science & Humanities Symposium. ďAbout half of the Navyís scientists and engineers will be eligible for retirement in just a few years, and the students taking part in this symposium will be the ones who fill their shoes,Ē Chief of Naval Research RAdm. Matthew Klunder said. The top three students from each category won undergraduate tuition scholarships of $12,000 for first place, $8,000 for second place and $4,000 for third place.


Japan Maritime Force Gets AAE USBLs, Transponders
The Japan Maritime Self Defense Force (JMSDF) has taken final delivery of a contract awarded to Applied Acoustic Engineering (AAE), based in Great Yarmouth, England, for the supply of more than 100 Alpha Portable USBL systems for use with naval search and rescue dive teams. JMSDF also specified more than 400 of AAEís 210 Micro/Remote transponders for its divers.
