Raytheon Receives First Production Order for US Naval SATCOM Programme


Raytheon has received the first production order for its next-generation NMT satellite communication terminals from the US Navy, marking a key milestone in the navy multiband terminal programme.
Valued at $37.6m, the initial production order calls for 22 systems that includes 15 ship, five submarine and two shore terminals, and other services and products.
NMT is a family of multibanded ship, submarine and shore communications terminals providing five times the bandwidth than other systems to the navy's military-band satellite communications.
NMT integrates its extremely-high-frequency / advanced extremely-high-frequency (EHF/AEHF) capability with two-way military Ka and X band, and the global broadcast service.
NMT is also compatible with wideband global SATCOM, backward compatible with legacy satellite systems, and interoperable with legacy navy and other service terminals.
Raytheon Integrated Communications Systems vice-president Brian McKeon said that NMT gave the navy secure communications connectivity to the latest satellite constellations that users can absolutely depend on, in a smaller package, and at much lower cost.
Raytheon was initially awarded the NMT prototype development phase in August 2003 and the procurement of terminals could potentially increase the programme's value to $1bn.

U.S. Navy Conducts COBRA System Flight Test from Fire Scout UAV

An MQ-8A Fire Scout prepares to land aboard USS Nashville.

AN/DVS-1 COBRA System to Provide Littoral Areas Reconnaissance
08:24 GMT, October 25, 2010 YUMA PROVING GROUND, Ariz. | The Navy successfully conducted the first flight test of the Coastal Battlefield Reconnaissance and Analysis (COBRA) Block I system at Yuma Proving Ground, Ariz., October 13, testing the system's performance on the Fire Scout vertical take-off unmanned aerial vehicle.

The AN/DVS-1 COBRA system allows the MQ-8B Fire Scout to conduct unmanned aerial reconnaissance in littoral areas, detecting minefields and obstacles to prepare for amphibious assaults. Incrementally development, the Block I upgrade was designed to specifically address the beach zone and inland areas.

"COBRA will provide valuable minefield, obstacle, and bathymetry information to the warfighter and amphibious task groups, information which is critical to amphibious assault planning," said Capt. John Hardison, deputy program manager for Mine Warfare Programs. "Successful completion of these tests is a significant leap forward in delivering this capability."

The Fire Scout, equipped with COBRA, conducted integration testing and flew for approximately 2 1/2 hours. Several successful tracks were completed in both pre-planned and operator-controlled modes and the systems conducted simulated missions. Take-off and landing went without incident, and the system completed all test scenarios.

With the successful completion of the first COBRA flight on Fire Scout, the system moves closer to delivery and deployment. The COBRA Block I system will enter low-rate initial production under a Small Business Innovative Research (SBIR) Phase III contract. Under this contract, the first production unit is scheduled for delivery to the fleet in fiscal year 2012.

An affiliated program executive office of the Naval Sea Systems Command, PEO LMW designs, delivers and maintains systems, equipment and weapons needed by the warfighter to dominate the littoral battle space, and provides assured access to the warfighter.

La marine américaine a annoncé qu'une vingtaine de femmes serviront à bord de sous-marins

Citation :

La marine américaine a annoncé jeudi qu'une vingtaine de femmes militaires commenceraient à servir à bord de sous-marins d'ici à la fin de l'année prochaine.

Les quatre sous-marins à intégrer les femmes militaires sont USS Wyoming, USS Géorgie, USS Maine et USS Ohio, ont précisé les autorités de la 10e escadrille de sous-marins de la marine dans un communiqué de presse. Chaque sous-marin disposera à bord de six femmes militaires.
L'USS Wyoming et l'USS Maine sont des sous-marins nucléaires lanceurs de missiles balistiques, alors que l'USS Georgia et l'USS Ohio sont des sous-marins nucléaires lanceurs de missiles de croisière.

L'intégration de femmes militaires dans le service des sous-marins est en cours depuis que le secrétaire à la Défense Robert Gates a notifié au Congrès en février la volonté du service de faire de la sorte. Suite à une révision du Congrès, la marine a déclaré en avril qu'elle commencerait à accepter les candidatures des femmes militaires pour l'entraînement à bord de sous-marins.

La 10e escadrille de sous-marins est sous commandement du contre-amiral Barry Bruner, qui dirige le détachement spécial des femmes à bord de sous-marins.

La marine américaine a tout d'abord permis aux femmes de servir à bord de navires non-combattants en 1973 et puis à bord de navires combattants en 1993, selon le Pentagone.

US Navy Tests New Warhead for Tomahawk Block IV Missile



The US Navy has successfully completed the first live test of the joint multi-effects warhead system (JMEWS), the new warhead for the Tomahawk block IV tactical cruise missile.
The JMEWS programme is designed to deliver a warhead that will provide blast-fragmentation capabilities to the missile and to introduce enhanced penetration capabilities into a single warhead.
Raytheon's Tomahawk programme director Gary Hagedon said the Tomahawk block IV missile includes a series of enhancements to provide the warfighter with a more capable system.
"JMEWS is the first of the planned system enhancements, and this test demonstrates that we have the right team in place to deliver these capabilities," he said.
The warhead detonated during the test conducted on 16 August 2010.

.S. Navy Awards Raytheon $14.8 Million for Helicopter Protection System

INDIANAPOLIS | The U.S. Department of the Navy's Naval Air Systems Command has awarded Raytheon Company (NYSE: RTN) a $14.8 million contract to produce dual pod countermeasures dispensers for U.S. Marine Corps CH-53 heavy-lift helicopters. Raytheon Technical Services Company LLC (RTSC) will manufacture the units at its Indianapolis operation.

Aircrews will use the pods to dispense chaff and flares to counter incoming missiles. The dual pods will replace current single-pod dispenser systems on the aircraft, enhancing the protection provided to crews and passengers.

"The CH-53 dual pod system will improve survivability of the aircraft in the combat zone," said Wayne Iurillo, RTSC vice president of customized engineering and depot support. "But most important, it will save lives of our warfighters."

US Navy Warships Could Get Powerful New Warheads


The US Navy warships in San Diego may be equipped with a new warhead, the Bunker Buster, for the Tomahawk block IV missile.
Raytheon business development manager Jeff Meyer said that the new joint multi-effects warhead system aimed to enhance the missile's ability to penetrate thicker concrete and steel structures.
"It just improves the capability of the system in different environments, whether it's hitting an aircraft on the airfield or if you want to go in and hit a command post that's underground a bit," he said.
Raytheon and the navy will continue to develop and test the new tandem warhead over the next few years and could integrate it with the missile in 2014 or 2015, according to CBS8.com.
The Tomahawk cruise missile has been used in virtually every combat operation till date, with more than 1,900 Tomahawk missiles fired in combat.
