Choctaw County Launches Successfully As Second JHSV for US Navy
Austal USA (Mobile, Alabama) successfully launched in October the second joint high-speed vessel (JHSV), the USNS Choctaw County (JHSV-2), which was christened in September. The 103-meter, 1,600-metric-ton catamaran is part of Austalís 10-ship, $1.6 billion contract with the U.S. Navy, which includes nine JHSVs.

The Choctaw County will undergo final outfitting and activation before sea trials and delivery to the Navy. It will operate out of Little Creek, Virginia, and is expected to begin conducting missions in the first quarter of fiscal year 2014.

Military Sealift Command will own and operate all the JHSVs under contract to be built for the Navy. The aluminum catamarans will have 20,000-square-foot mission-bay areas that can be reconfigured to adapt quickly to various missions, such as carrying containerized portable hospitals to support disaster relief or transporting tanks and troops.

The JHSV-class suits the goal of forward-basing to reduce the number of overseas bases by equipping more forward-deployed ships with troops and gear, the Navy said. The JHSVs will be able to transport 600 tons of military troops, vehicles, supplies and equipment 1,200 nautical miles at an average of 35 knots and can operate in shallow-draft, austere ports and waterways.


Hydroid to Provide Six REMUS AUVs for German Navy
After trials by the German Bundeswehr Technical Center for Ships and Naval Weapons (WTD 71) in Eckernförde, Germany, the Federal Office of Defence Technology and Procurement has placed a contract for six REMUS 100 AUVs manufactured by Hydroid Inc. (Pocasset, Massachusetts) to enhance the capabilities of the German Navyís mine divers.

Delivery and operational training will occur in the next 12 months, Hydroid said in October.

The REMUS 100 AUV is equipped with side scan sonar and other sensors. It navigates by transponder interrogation and Doppler velocity log-aided inertial dead reckoning in preprogrammed missions. The recorded data will be used to search for mines, lost objects, debris and wrecks or to collect topographic ocean-floor mapping for hydrographic and scientific applications.


Navy to Name Newest Research Vessel After First Man Who Set Foot on the Moon
The newest U.S. research vessel will be named the RV Neil Armstrong, after the recently deceased astronaut who was the first man to set foot on the moon. The ship, which is the first oceanographic research vessel named for a space explorer, will be operated by the Woods Hole Oceanographic Institution (WHOI).

WHOI was selected by the Office of Naval Research to operate AGOR-27 (Auxiliary General Oceanographic Research), one of two new research vessels to be built by the U.S. Navy that will now be known as the Armstrong-class.

The 238-foot Neil Armstrong, scheduled to launch in early 2014 and be ready for service in 2015, will be based in the East Coast and deployed for oceanographic and ocean-engineering missions. It is also expected to support new initiatives in ocean observing at high latitudes and new studies of North Atlantic ecosystems and their sustainability.

The vessel will include over-the-side handling systems and hull-mounted bottom-mapping and acoustics transducers to improve safety and enable operation in higher sea states than existing vessels of its size.


GE Energy Completes Delivery of Electric Propulsion Motors to UK Royal Navy
GE Energy Power Conversion (Rugby, England) has delivered the last of eight propulsion motors, 110-ton GE advanced induction motors, for two aircraft carriers under construction for the U.K.ís Royal Navy.

The Queen Elizabeth and the Prince of Wales, each 280 meters long with a displacement of 65,000 tons, will be the largest warships in the world to use fully electric propulsion systems, as well as the Royal Navyís largest warships.

With their integrated full electric propulsion systems, the warships are expected to consume no more fuel during typical routine operations than the smaller 22,000-ton predecessor carriers.

This approach is designed to improve ship survivability by decoupling the placement of the turbines and the generators from the propellersí mechanical drive. Power generation and propulsion equipment are instead distributed across several independent compartments rather than concentrated into a single space or small number of spaces.

GE Energy Power Conversion won a contract in 2008 to deliver the major elements of the integrated full electric propulsion systems for the new Queen Elizabeth-class carriers.
