US Navy’s First Amphibious Assault Ship En Route to California
The amphibious assault ship America (LHA-6) has departed Huntington Ingalls Industries’ (Newport News, Virginia) Shipbuilding division, sailing to the West Coast in preparation for its October 11 commissioning in San Francisco, California.

America is the first ship in the U.S. Navy’s new class of amphibious assault ships. The ship is 844 feet long and 106 feet wide and displaces 44,971 long tons. Its fuel-efficient gas turbine propulsion system can drive the ship in excess of 20 knots.


REP14-Atlantic Tests Unmanned Vessel Networks off Portugal Coast
REP14-Atlantic was conducted in the Lisbon Naval Base and off the coasts of Sesimbra and Sines, Portugal, from July 7 to 24. It was a joint exercise of the Portuguese Navy, the NATO Centre for Maritime Research and Experimentation and the faculty of engineering of University of Porto.

The exercise included several ASVs, AUVs and unmanned aerial vehicles equipped with different sensors and acoustic payloads, deployed from Portuguese Navy ships NRP Pégaso, NRP Auriga, submarine NRP Arpão and the NATO Research Vessel Alliance.

The goal was to test the networks of unmanned maritime vehicles in anti-submarine warfare, mine countermeasures, maritime security, environmental knowledge, search and rescue, and maritime law enforcement operational scenarios.

Participants included the Monterey Bay Research Institute, the University of Rome, the Norwegian University of Science and Technology, the Royal Institute of Technology (U.K.), the German Defence Research and Testing Agency, EvoLogics (Berlin, Germany) and OceanScan (Matosinhos, Portugal).


Third MUOS Satellite Completes Environmental Testing
Lockheed Martin (Bethesda, Maryland) has successfully completed environmental testing of the U.S. Navy’s third Mobile User Objective System (MUOS) satellite. It recently cleared thermal vacuum trials, which validate performance in simulated space conditions, and the satellite is now in final check out. The Navy plans to launch this addition to the constellation in January 2015.


Marine Mammals Seem Unperturbed by Midfrequency Sonar
A new report demonstrates the viability of a new method to estimate received sound levels during real scenarios and analyzes movements of satellite-tagged individuals of three species of marine mammals exposed to U.S. Navy midfrequency active sonar around Kauai’s Pacific Missile Range Facility.

Received sound levels were compiled and movements tracked for two rough-toothed dolphins, a bottle-nose dolphin and a short-finned pilot whale. The bottlenose dolphin showed no large-scale movements out of the area during sonar exposures, and a short-finned pilot whale actually moved toward areas of higher sonar levels during the third day of a three-day period of regular mid-frequency active sonar use.


Raytheon Sets Up Zumwalt Scholarship
Raytheon (Waltham, Massachusetts) has established the Raytheon-Zumwalt Scholarship to support naval families and champion the educational pursuits of future scientists, technologists and engineers who exemplify Zumwalt’s legacy.

Adm. Elmo R. Zumwalt, Jr., as chief of naval operations, was a transformational leader widely recognized for modernizing the U.S. Navy. Harrison Ballard is the first recipient of the Raytheon-Zumwalt Scholarship. The $20,000 scholarship is intended for STEM-related studies.


US Navy Orders Iver3s, Updated Iver2s
OceanServer Technology (Fall River, Massachusetts) has received orders for four Iver3 AUVs across three different U.S. Navy contracts. The new vehicles will include two standard Iver3-580 units and two new Iver3-450 Nano AUVs.

Two Iver3-580 systems have already been delivered to the Navy EOD Group, and the other two Iver3s will be delivered within the next few months to the Naval Oceanography Special Warfare Center.

OceanServer will also modernize three older Iver2 systems with higher-resolution sonar and new DVL units that improve navigation and collect current profile data.
