P-3C concerns may freeze deliveries from Lockheed plant

Citation :

US government officials may freeze deliveries from a major Lockheed Martin aircraft factory after finding "quality issues" on P-3C Orion wing components.

A team of inspectors from the Defense Contract Management Agency and Naval Air Systems Command are assessing Lockheed's plans for fixing the root causes of the issues, the company says.

If the inspectors decide Lockheed's plan is inadequate, the team can order a freeze on all deliveries from and new contracts for the factory in Greenville, South Carolina, or order Lockheed to develop another plan.

Lockheed expects the inspectors "will acknowledge that we are making good progress and have confidence in our ability" to fix the causes of the quality problems in Greenville, the company says.

Lockheed's Greenville site is spread across 65Ha (161 acres), where aircraft maintenance and overhaul services are performed in 16 hangars with 31 bays. It is installing outer wing assemblies on 17 P-3Cs operated by the US Navy, plus about 40 more for other P-3 customers.
The inspections began earlier this year after "quality issues" were discovered on corner wing fittings on P-3Cs delivered to the USN, Lockheed says.

The company was given a 180-day deadline to develop the correction plan, which expires on 20 November.

US Congress Could Approve Littoral Combat Ships Deal
Congress is expected to approve US Navy plans to alter a wording change to move forward with a plan to buy littoral combat ships from two builders.
The navy has plans to buy 20 ships, costing $480m each, of two different designs from Marinette Marine, which is working with Lockheed, and an Alabama yard that is contracted by Austal.
A review of the proposals from both companies indicated that the navy could purchase both designs without allocating more funding for the programme, according to Green Bay Press Gazette.
Marinette Marine CEO and president Richard McCreary said the change could be approved within two weeks.
"We have a lot of political support. We believe this will get done because it's truly a language change, it's not new money ... but again it's a work in progress," he said.
The dual purchase option will be approved by Congress by the middle of December and if the option is not approved, a single supplier will be selected.

Raytheon Awarded $32 Million U.S. Navy Bomb Rack Contract


The U.S. Navy’s Naval Air Systems Command has awarded Raytheon Company (NYSE: RTN) a $32.4 million cost-plus-incentive-fee contract for engineering and manufacturing development of the BRU-69/A Multi-Purpose Bomb Rack system.

The MPBR will replace several bomb racks currently deployed on Navy aircraft. It will use pneumatic energy instead of an explosive charge to release the weapon from the rack. Advanced electronics built into the bomb rack will ensure the new system is compatible with current and future precision-guided weapons, or “smart bombs.”
The MPBR system will be designed and built at the Raytheon Technical Services Company LLC (RTSC) facility in Indianapolis, Ind. The engineering and manufacturing development phase of the program will be completed in 2014, when low rate initial production is expected to begin, with full scale production starting in 2017.
For this program, RTSC is teamed with Ultra Electronics Precision Air Systems. Raytheon will design, develop and build the bomb rack, while Ultra will produce the airborne High Pressure Pure Air Generator that produces the pneumatic energy for the release system.
“Because of its low-maintenance, high-reliability design, the MPBR is expected to provide substantial life-cycle cost savings, compared with existing racks,” said RTSC Customized Engineering and Depot Support Vice President Wayne Iurillo. “The single configuration for multiple stores will also be designed to significantly increase savings.”

Lockheed Martin-led Industry Team Launches Nation’s Third Littoral Combat Ship



MARINETTE, Wis. | The Lockheed Martin [NYSE: LMT]-led industry team today launched the nation’s third Littoral Combat Ship (LCS), Fort Worth, at the Marinette Marine shipyard.

The 389-foot Fort Worth was launched into the Menominee River. Just prior to its launch, the ship’s sponsor, Congresswoman Kay Granger of Texas, christened Fort Worth with the traditional smashing of a champagne bottle across the ship’s bow.

“It is an incredibly rewarding experience to see Fort Worth launch into the water – on time and on budget,” said Orlando Carvalho, president of Lockheed Martin’s Mission Systems and Sensors business. “The team’s strong performance and hard work in bringing Fort Worth to this point illustrates our ability to meet the Navy’s need for a class of affordable, multi-mission combatants.”

“Serving as the USS Fort Worth’s sponsor is one of the proudest moments in my career,” Congresswoman Granger said. “This is just the beginning of a commitment I am making with everyone in Fort Worth to all those who will sail on the ship over the course of her life. The enthusiastic residents of our fine city and I have pledged to take great care of this magnificent ship and its crew. With ‘Grit and Tenacity’ we will once again demonstrate our community’s key principles of service and patriotism.”

In March 2009, the U.S. Navy awarded the Lockheed Martin-led industry team a contract to construct Fort Worth. Only 20 months later, the ship is 80 percent complete. Now formally christened and launched, Fort Worth will continue to undergo outfitting and testing at Marinette Marine before delivery to the Navy in 2012.

Prior to constructing Fort Worth, the Lockheed Martin-led team designed and constructed USS Freedom (LCS 1), which was deployed in February and is now based in its homeport of San Diego, Calif. USS Freedom was christened in 2006 and delivered to the Navy in 2008.

In addition to Marinette Marine Corporation, a Fincantieri company, the Lockheed Martin-led industry team for Fort Worth includes naval architect Gibbs & Cox as well as best-of-industry domestic and international companies.

U.S. Navy Announces USS Nimitz Homeport Change to Everett, Wash

09: The U.S. Navy announced today that the nuclear aircraft carrier USS Nimitz (CVN 68) will be homeported at Naval Station Everett, Wash., upon completion of the ship’s docking planned incremental availability (DPIA) maintenance at Bremerton, Wash., in December 2011. After a thorough analysis and review of related factors, Secretary of the Navy Ray Mabus decided to homeport Nimitz in Everett following the departure of USS Abraham Lincoln (CVN 72) in early fiscal 2012 for a four-year refueling complex overhaul (RCOH) in Hampton Roads, Va. Abraham Lincoln is presently deployed to the Central Command area of responsibility. Nimitz was homeported in San Diego from Nov. 13, 2001, to Dec. 6, 2010, when the ship administratively shifted homeport to Bremerton for the duration of its year-long maintenance period. The Navy’s decision to homeport Nimitz in Everett ensures long-term strategic dispersal of aircraft carriers on the West Coast and yields estimated cost savings and avoidance totaling more than $100 million. “Many factors were considered here, including the quality of life for our sailors and their families, and the considerable cost savings to the American taxpayers,” said Mabus. “Maintaining a carrier in Everett will ensure long-term strategic dispersal and operational readiness of our fleet which is critical to our national security.” Nimitz crewmembers who opted not to move family members during the extended maintenance period in Bremerton will be afforded the opportunity to conduct permanent change of station moves for eligible family members from San Diego to Bremerton and, subsequently, to Everett after completion of the DPIA. The first in its class of 10 nuclear-powered aircraft carriers, Nimitz was commissioned May 3, 1975, and was homeported in Bremerton from 1987 to 1997. With a planned 50-year service life expectancy, Nimitz conducted a RCOH at Newport News, Va., from 1998 to 2001. Nimitz is commanded by Capt. Paul O. Monger.

La marine américaine teste avec succès un canon électromagnétique
(AFP) –

WASHINGTON — Un canon électromagnétique, qui permet de tirer un projectile à 200 km de distance et à cinq fois la vitesse du son, a été testé avec succès vendredi aux Etats-Unis, battant au passage un record de puissance, a annoncé la marine américaine.

Il s'agit de l'étape la plus récente dans les efforts de l'US Navy pour mettre au point un canon futuriste qui permet de lancer des projectiles sans poudre ou autre propulseur chimique.

Le canon, en fait une sorte de grille-pain à rallonge, maintient en place deux rails entre lesquels est posé un projectile et permet de tirer des munitions grâce au passage d'un courant électrique très puissant dans les rails.

L'essai du "railgun" s'est déroulé dans la journée au Centre de recherche de la Navy basé à Dahlgren en Virginie (est), a indiqué cet institut dans un communiqué.

La puissance du tir a atteint 33 mégajoules, soit trois fois plus qu'un précédent essai effectué en janvier 2008 (10,64 mégajoules). Un mégajoule correspond à l'énergie dégagée par une voiture de une tonne qui s'écraserait contre un mur à plus de 160 kmh.

Un tir de projectile à la puissance de 33 mégajoules permet d'atteindre mach 5, soit cinq fois la vitesse du son, a expliqué la marine.

"Ce tir montre que la marine peut tirer des projectiles à une distance d'au moins 110 miles nautiques" (200 km), soit près de 20 fois plus loin que les engins embarqués actuellement en mer, s'est félicité l'amiral Nevin Carr, chef de la recherche navale.

Un tel canon permettrait de tirer de plus loin --ce qui protège le navire d'une éventuelle riposte ennemie-- mais aussi d'améliorer les conditions de sécurité des équipages qui n'auront plus à manipuler des obus ou des missiles bourrés de matières explosives.

"Le test du canon électromagnétique effectué aujourd'hui démontre l'intérêt tactique de cette technologie, qui pourrait un jour compléter l'arsenal des systèmes de combat des bâtiments de surface", a ajouté l'amiral cité dans le communiqué.

Unmanned Strike Jet Nearly Set For First Flight



The first unmanned aircraft designed as a carrier-based strike jet is almost ready to take to the air for the first time, U.S. Navy officials have confirmed.
Northrop Grumman's X-47B Unmanned Combat Air System Demonstration (UCAS-D) drone has been performing taxi tests for several weeks at Edwards Air Force Base, Calif., as engineers run the aircraft through a long series of pre-flight tests and checks. Related Topics

Program officials had hoped for a flight by mid-December, but weather and other factors have delayed the event. Officials were reluctant to specify an exact date, but are hopeful the flight will take place before the end of the year.
Two X-47Bs have been built by Northrop's Aerospace Systems sector under a 2007 development contract. The stealthy aircraft, which resembles a miniature B-2 bomber - also built by Northrop - is intended to test the concept of operating a small, unmanned, combat jet from aircraft carriers.
Although numerous technical and command-and-control issues need to be addressed to bring the concept to maturity, war planners have routinely been using X-47s in war games as part of a carrier strike group. In some cases, they have even swapped out the manned air wing for an all-UCAS wing, with, reportedly, great success.
Northrop's work on the program includes the design and development of airborne precision-guided positioning system algorithms to help navigate the aircraft, and autonomous aerial refueling technology to keep the planes aloft - perhaps for several days at a time.
The first plane was to have taken to the air in late 2009 under the original contract, with the first at-sea tests on a carrier to have been in 2011, but those dates have been pushed back. Initial seagoing tests now are scheduled for early 2013.
The single-engine, tailless X-47B has a wingspan of 62 feet and is 38 feet long. It is designed to carry 4,500 pounds of weapons in its payload bay, reach high subsonic speeds, and fly to altitudes of about 40,000 feet. Without refueling, it should be able to operate at ranges up to 2,100 nautical miles and stay in the air for more than six hours.
Lockheed Martin, Pratt & Whitney and GKN Aerospace are teamed with prime contractor Northrop on the UCAS-D program.
