Lockheed Martin Receives $1.05 Billion, Five-year U.S. Navy Contract for MH-60R/S Cockpits and Integrated Systems
WASHINGTON, April 5, 2012 /PRNewswire/ -- The U.S. Navy awarded Lockheed Martin (NYSE: LMT) a $1.05 billion, five-year contract to provide more than 200 digital cockpits and integrated mission systems and sensors for the Navy MH-60R "Romeo" and MH-60S "Sierra" helicopters.
"U.S. Navy crews operating the 300-plus MH-60 Romeo and Sierra helicopters already in the fleet understand just how critical these aircraft are to protecting our ships from surface and undersea threats," said Rear Adm. Paul Grosklags, U.S. Naval Air Systems vice commander. "This contract represents the Navy's commitment to build and field the most technologically advanced maritime helicopter fleet in the world."
Specifically, the new multi-year contract includes 162 cockpits, integrated missions systems and sensors for MH-60R "Romeo," an anti-surface and anti-submarine warfare helicopter. It also funds 62 digital cockpits to complete the Navy's program of record for Sierra aircraft, used for ship-to-ship cargo resupply, search and rescue, and close-in defense of Navy ships.
A multi-year procurement contract such as this one must meet rigorous criteria before being approved by Congress, including being able to demonstrate double-digit cost savings.
"This contract award ensures uninterrupted, on-time deliveries of the MH-60R and MH-60S helicopter to the U.S. Navy fleet," said Dan Spoor, vice president of aviation systems for Lockheed Martin's Mission Systems & Sensors business. "Plus the multi-year structure, versus an annual contract, allows us to provide our customer with more than 10 percent savings annually, surpassing Pentagon cost predictions."
Lockheed Martin provides the digital cockpit common to the MH-60R and MH-60S, and integrates the mission systems and sensors aboard the MH-60R helicopter in Owego, N.Y.
Both aircraft are designed and manufactured by Sikorsky Aircraft, Stratford, Conn.
Headquartered in Bethesda, Md., Lockheed Martin is a global security and aerospace company that employs about 123,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation's net sales for 2011 were $46.5 billion.

Boeing Receives Additional Laser JDAM Contract from US Navy
The Boeing Company received a $12.5 million contract from U.S. Naval Air Systems Command (NAVAIR) on March 12 for 1,116 Laser Joint Direct Attack Munition (Laser JDAM) sensors. This is NAVAIR’s third Low Rate Initial Production order for its Direct Attack Moving Target Capability (DAMTC). It follows an $8.3 million NAVAIR order for 700 laser sensors on Jan. 31 that allows the U.S. Air Force to maintain its Laser JDAM combat inventory levels.
Deliveries for both laser sensor contracts will begin in April and continue through February 2013.
“The Boeing JDAM family of weapons has been used by warfighters and their allies around the globe for more than a decade,” said Debbie Rub, Boeing vice president and general manager, Missiles and Unmanned Airborne Systems. “The advanced capability of Laser JDAM offers our customers unparalleled accuracy and flexibility against a wider range of emerging threats on today’s battlefields.”
JDAM is a low-cost guidance kit that converts existing unguided free-fall bombs into near precision-guided weapons. Laser JDAMs have added the capability to prosecute moving targets, maritime threats and other relocatable targets of opportunity. Boeing intentionally designed its JDAM kit to be modular so that the product can mature with a variety of other technological upgrades, such as wing kits that triple its range, improved immunity to GPS jamming, and an all-weather radar sensor.
“Laser JDAMs are being used more and more by the U.S. Navy and Air Force,” said Kristin Robertson, director, Boeing Direct Attack Weapons. “The laser variant has been incredibly effective in attacking moving targets accurately and reliably, with minimal collateral damage. Adding the laser sensor to a conventional JDAM kit is an affordable option that’s easy for ordnance crews to install and very straightforward for pilots already familiar with JDAM.”
Boeing completed the development and testing cycle for its Laser JDAM less than 17 months after it was identified as an urgent operational need in early 2007. The company delivered the first production laser sensor kits to the U.S. Air Force in May 2008 and to the U.S. Navy in October 2008. Laser JDAM was successfully employed by the Air Force in combat in Iraq in August 2008. NAVAIR’s first Low Rate Initial Production order under DAMTC was a March 2011 contract for 700 Laser JDAM kits.
Since starting JDAM production in 1998, Boeing has built more than 230,000 JDAM tail kits in its St. Charles, Mo., facility on time and at cost for use by the U.S. Department of Defense and 26 international militaries.

General Dynamics NASSCO Begins Construction of the Future USNS John Glenn
Posted on April 17, 2012 by Mary Montgomery
SAN DIEGO – General Dynamics NASSCO today began construction of the future USNS John Glenn, the second ship of the U.S. Navy’s Mobile Landing Platform (MLP) program. The 765-foot long ship is scheduled to be delivered to the Navy in the first quarter of 2014. When in service, the ship will be used as an offshore staging area for Navy and U.S. Marine Corps personnel and equipment.
NASSCO has construction contracts to build a total of three Mobile Landing Platform ships. The first ship of the class, the future USNS Montford Point, is currently 48 percent complete at the San Diego shipyard. Once delivered to the fleet, MLP ships will join the Maritime Prepositioning Force squadrons that are strategically located around the world to enable rapid response in a crisis. These ships will provide a “pier at sea” that will become the core of the Navy/Marine Corps sea basing concept. This capability will allow prepositioning ships to offload equipment and supplies to the MLP for transshipment to shore by other vessels.

L’US Navy met en vente son catamaran furtif Sea Shadow 30 avril 2012 – 12:41
Il ne reste plus que quelques jours pour tenter d’acquérir le Sea Shadow (ou IX-529), un catamaran furtif conçu dans la plus grande confidentialité, au cours des années 1980, par le chantier naval de Redwood City, en Californie, lequel appartient à Lockheed-Martin.
En effet, et après avoir vainement tenté de le placer auprès d’un musée, l’US Navy a décidé de se séparer de ce bâtiment pour le moins singulier en le mettant aux enchères sur le site GSA Auctions.
Au 30 avril, le seuil des 100.000 dollars a été dépassé, ce qui peut paraître cher lorsque l’on sait que l’acquéreur n’aura pas le droit de naviguer avec le Sea Shadow puisqu’il devra être démantelé. En fait, ce qui fait son prix, ce sont les 50 tonnes de matéraux avec lesquels il a été construit.
Long de 50m pour 21m de large, ce navire a été contruit en 1985 pour 50 millions de dollars. Il s’agissait alors de mettre au point un bâtiment indetectable aux radars et difficilement repérable à l’oeil nu. D’où, d’ailleurs, son profil particulier. A propulsion diesel-électique, le Sea Shadow pouvait atteindre une vitesse comprise de 10 à 14 noeuds. Non armé, il était mis en oeuvre par un équipage de 10 marins
Son existence n’a été révélée qu’en 1993, soit deux ans après la chute de l’URSS et le programme Sea Shadow a officiellement pris fin un an plus tard. Mais ce navire a toutefois continué à être ponctuellement utilisé à des fins d’expériences jusqu’en 2006. http://www.opex360.com/

US Navy launches official Request for Information (RFI) for F/A-XX strike fighter
The US Navy has launched mid-April an official RFI for the F/A-XX carrier-based strike fighter. The F/A-XX is intended to replace both F/A-18E/F Super Hornet fighter and EA-18G Growler electronic warfare aircraft currently in service in the US Navy by the years 2030ies.
The official RFI for the sixth generation fighter, issued by the Department of the Navy Naval Air Systems Command Aircraft Division, goes as follow:
The Director for Air Warfare (OPNAV N98) has requested NAVAIR Warfare Analysis and Integration Department (AIR-4.10) to conduct trade space refinement as a precursor to an analysis of alternatives for candidate strike fighter aircraft replacements for the FA-18E/F and EA-18G.
F/A-XX concept (Picture: Boeing)
CAPABILITY DESCRIPTION:The intent of this research is to solicit Industry inputs on candidate solutions for CVN based aircraft to provide multi-role capability in an A2AD operational environment. Primary missions include, but are notlimited to, air warfare (AW), strike warfare (STW), surface warfare (SUW), and close air support (CAS). Also consider the ability of your concept to provide other capabilities currently provided by strike fighteraircraft, such as organic air-to-air refueling (AAR), Tactical Reconnaissance, Surveillance and Target Acquisition (RSTA), and airborne electronic attack (AEA). The trade space refinement activity will characterize a broad trade space, to include unmanned, optionally manned and manned aircraft. System attributes and system capabilities will be considered in the context of cost and affordability. Concepts that are derived from legacy aircraft, “clean sheet” new design aircraft, as well as innovative technology concepts specifically tailored for the operational context are all relevant. Please provide a separate whitepaper for each technology concept or family of related and complementary technology concepts; multiple white papers may be provided
F/A-XX artist impression (Picture: Boeing)
As a top level summary of some of the required system capabilities, the air vehicle should be capable of addressing the following needs: 1.Capable of operating from CVN 68 and CVN 78 class aircraft carriers, as part of the Carrier AirWing (CVW), with minimal impact on the ship configuration and the operations of the rest of theCVW.
2.This aircraft will be a complementary CVW asset to the F-35C and an unmanned persistent intelligence, surveillance, and reconnaissance (ISR) vehicle with precision strike capability.
3.The ability to conduct persistent, penetrating operations in an A2AD operational environment.
4.The ability for an IOC in the 2030 timeframe. If a spiral approach to incorporation of systems and/or technology to achieve full operational capability is employed, provide the timeline toachieve full capability.

General Dynamics Delivers Submarine Mississippi to U.S. Navy 363 Days Ahead of Schedule
GROTON, Conn., May 2, 2012 /PRNewswire via COMTEX/ -- General Dynamics Electric Boat today delivered the nuclear-powered attack submarine Mississippi (SSN-782) to the U.S. Navy 363 days ahead of contract schedule and more than $60 million below target cost. Electric Boat is a wholly owned subsidiary of General Dynamics.
John Holmander, vice president and Virginia program manager for General Dynamics Electric Boat, noted that Mississippi was at the most combat-ready state of any Virginia-class submarine at delivery. He credited the Navy, the shipbuilders and the supplier base for achieving significant shipbuilding benchmarks with the delivery of Mississippi.
Mississippi is the ninth ship of the Virginia Class, the most advanced submarines in the world. These ships are providing the Navy with the capabilities it requires to retain its undersea dominance well into the 21st century. Mississippi will join the fleet in a commissioning ceremony June 2 in Pascagoula, Miss.
"When compared with the lead ship of the Virginia Class, we have reduced our construction span time by two years, and implemented improvements that reduced construction labor hours by 30 percent," Holmander said.
"These are remarkable achievements that demonstrate the skill and commitment of everyone involved in the Virginia-class submarine program," he said. "This kind of performance is the best way to help the Navy attain its shipbuilding goals and ensure our continuing success as a business."
Electric Boat and its major subcontractor, Newport News Shipbuilding, have received contracts to build the first 18 submarines of a planned 30-ship Virginia Class under a unique teaming agreement.

La seconde génération de missile antimissile balistique en action
Tir de SM-3 Block 1B le 9 mai sur l'USS Lake Erie
La seconde génération de défense antimissile balistique américaine a franchi un nouveau pas. Le 9 mai, dans l'océan Pacifique, le croiseur USS Lake Erie a tiré le nouveau missile SM-3 Block 1B, qui a intercepté avec succès une cible simulant un missile balistique à courte portée. L'engin avait été lancé depuis le centre d'essais de Kauai, à Hawaii. Equipé avec la seconde génération du système de défense Aegis BMD 4.0.1, le Lake Erie a pu détecter et pister la cible grâce à son radar SPY-1. Le système de combat a, alors, offert une solution d'interception, permettant de lancer le SM-3 Block 1B vers sa cible et la détruire. Pour mémoire, les précédents tirs avaient été réalisés avec un système Aegis BMD 3.6.1 et des missiles SM-3 Block 1A. « Le SM-3 a manoeuvré jusqu'à un point dans l'espace, comme désigné par la solution de tir, et a libéré son ogive cinétique. Celle-ci a acquis la cible et, utilisant seulement la force d'un impact direct, a engagé et a détruit la menace », explique la marine américaine.
Tir de SM-3 Block 1B le 9 mai
Le couple Aegis BMD 4.0.1 / SM-3 Block 1B va permettre d'améliorer la capacité du système de défense américain contre une gamme de missiles balistiques à plus longue portée et des engins de plus en plus sophistiqués, tout en construisant une parade contre des attaques massives. Le SM-3 Block 1B dispose d'un autodirecteur infrarouge à deux couleurs, qui améliore la sensibilité pour l'acquisition de cibles à plus longue portée et la rapidité du traitement de données pour l'identification. Le missile compte aussi un processeur de signal amélioré et un nouveau système de commande d'altitude pour manoeuvrer l'engin dans sa phase d'interception
Tir de SM-3 sur un Arleigh Burke
Arleigh Burke
Lancé à la fin des années 90, le programme de défense anti-missile balistique américain a connu de nombreux tirs d'essais depuis 2001, avec 53 interceptions réussies sur 67 lancements effectués. L'Aegis Ballistic Missile Defense (BMD) compte, plus particulièrement, 22 neutralisations de cibles sur 27 tirs réalisés. Le dispositif vise à apporter un bouclier anti-missile aux Etats-Unis et à leurs alliés. Les moyens d'interception sont mis en oeuvre depuis les croiseurs du type Ticonderoga et les destroyers du type Arleigh Burke. En dehors des côtes américaines, le dispositif présente l'avantage, du fait de sa nature navale, de pouvoir être déployé partout dans le monde, là où les bâtiments sont positionnés. Cette capacité est, par exemple, disponible dans la région du golfe Persique et en Asie du sud-est. Washington a aussi décidé, pour procurer un parapluie à l'Europe dans le cadre de l'OTAN, de baser quatre Arleigh Burke en Espagne en 2014 et 2015. Le Japon bénéficie également de cette technologie, mise en oeuvre depuis les destroyers du type Kongo, dérivés des Arleigh Burke.

Il s'agit du futur USS North Dakota (SSN 784), dont la livraison est prévue en 2014, soit cinq ans après la découpe de la première tôle. Long de 114.9 mètres, ce SNA affichera un déplacement de 7800 tonnes en plongée. Capable d'atteindre la vitesse de 34 noeuds, il disposera de 12 tubes pour missiles de croisière Tomahawk et 4 tubes pour le lancement de 26 torpilles Mk48. Le premier bâtiment de la série, l'USS Virgina (SSN 774), a été livré à l'US Navy en 2004. L'USS Mississipi (SSN 782) doit être mis en service le mois prochain, alors que le baptême de l'USS Minnesota (SSN 783) est prévu en novembre. M&M

Construit par les chantiers Austal de Mobile (Alabama), l'USNS Spearhead, premier des 10 Joint High Speed Vessel (JHSV) commandés par l'US Navy, a réalisé avec ses succès sa première campagne d'essais en mer. Le bâtiment, qui a appareillé pour la première fois fin avril, a navigué dans le golfe du Mexique, établissant une première pointe de vitesse à 35 noeuds. Longs de 103 mètres, les JHSV sont des catamarans en aluminium conçus pour le transport rapide de troupes, de véhicules et de matériel. Devant pouvoir atteindre la vitesse de 43 noeuds, ils pourront transporter 600 tonnes de matériel et héberger 146 personnes en cabines, avec également la possibilité de d'accueillir 312 autres passagers sur des sièges. Dotés d'une plateforme pour un hélicoptère lourd, ils comptent aussi, sur l'arrière, une rampe permettant de débarquer le fret et les véhicules transportés. C'est en 2008 que le programme a été notifié à Austal, le coût des 10 JHSV étant de 1.6 milliard de dollars. Alors que la tête de série est en essais, le second navire est en achèvement, la mise sur cale du troisième étant intervenue le 3 mai au chantier de Mobile, où Austal réalise également les Littoral Combat Ship (LCS) de la classe Independence.
