Cyclone Prediction System Transitions to Operations
Developed by the U.S. Naval Research Laboratory Marine Meteorology Division located in Monterey, California, the Navyís Fleet Numerical Meteorology and Oceanography Center has entered the Coupled Oceanographic and Atmospheric Mesoscale Prediction System-Tropical Cyclone (COAMPS-TC) into full-scale operations.

Focusing on the development and transition of a fully coupled, air-ocean-wave prediction system, the COAMPS-TC model includes nonhydrostatic atmospheric dynamics, multiple nested moving grids that follow the center of the storm, and improved boundary layer and cloud physical parameterizations.

The forecasts and products produced by COAMPS-TC will be used by the Department of Defense Joint Typhoon Warning Center and NOAAís National Hurricane Center to predict the intensity, dynamics and location of tropical cyclones.

US Navy Purchases Six Iver AUVs
OceanServer Technology (Fall River, Massachusetts) has received purchase orders for six new Iver AUVs across three contracts. The vehicles will be utilized by four U.S. Navy directorates for defense-related applications. All six systems will be delivered within the next few months.

The Iver platform has high-resolution imaging in littoral waters. The vehicle design allows for a range of water quality sensors, remote helm applications and in-water communications.

Iver AUV models have OceanServerís VectorMap Mission Planning and Data Presentation tool. The VectorMap program can input NOAA ENCs or georeferenced charts, maps or photo images, allowing the operator to develop AUV missions using point-and-click navigation.

New Navy Transportation Tool
A Web-based tool sponsored by the Office of Naval Research brings an Expedia-like search capability to Navy planners looking to move personnel or equipment around the world.

The Transportation Exploitation Tool (TET) is software that allows transportation planners to find available space among military and commercial flights, and ship movements, that take place each day. It enables supplies or personnel to arrive at a destination in an efficient way and provides the U.S. Navy, Marine Corps and Coast Guard cost savings.

The new system has saved the naval services more than $30 million in transportation costs, officials say. When fully implemented, savings estimates range to more than $200 million over 10 years.

The system was developed with coordinated support from several Office of Naval Research teams.

Peruvian Navy Tall Ship to be Built with GL
La Unión, the new Peruvian Navy tall ship sail training vessel, will be constructed under the supervision of classification society Germanischer Lloyd (Hamburg, Germany). Tall ships are used in navies around the world to build leadership and foster teamwork under challenging conditions at sea.

The keel laying for the new ship took place at the Peruvian shipyard where the new vessel will be constructed. The 50-million-dollar project will involve more than 800 people working on the vesselís construction, including regional craftsmen from Peru who will provide the carved wood used on the ship.

The design of the vessel is a four-masted barque, with a 3,400-meter-square sail area. Each of the masts is anchored in the keel and stretches some 60 meters in height.

Northrop Grumman to Supply Steering Gear Systems
Northrop Grumman Corp. (Falls Church, Virginia) has been awarded contracts totaling $14.4 million by General Dynamics Bath Iron Works (Bath, Maine) and Huntington Ingalls Industries (Newport News, Virginia) to supply the steering gear system for three new DDG-51-class Arleigh Burke destroyers.

The steering gear system functions in the control and maneuverability of the ship and is linked to the integrated bridge, as well as the navigation and inertial navigation systems.

Northrop Grumman has been the provider of the steering gear system for the DDG-51-class since production began during the 1980s. This contract brings the programís total to 69 steering systems. The steering systems will be installed on the DDGs at the Bath Iron Works shipyard in Maine and the Huntington Ingalls shipyard in Mississippi before the destroyers are delivered to the U.S. Navy.
