Boeing Delivers 1st P-8A Poseidon Production Aircraft to US Navy
SEATTLE, March 6, 2012 — Boeing [NYSE: BA] on March 4 officially delivered the first production P-8A Poseidon aircraft to the U.S. Navy in Seattle. The P-8A is the first of 13 anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance aircraft Boeing will deliver as part of a low-rate initial production (LRIP) contract awarded in 2011.
“Delivering this capability to the warfighter is the ultimate goal and we’re proud to be able to meet our commitment and hand over the P-8A ‘keys’ to the Navy fleet,” said Chuck Dabundo, Boeing vice president and P-8 program manager. “This is a great day for Boeing, our supplier teammates and our Navy customer.”
“The Navy fleet is more than ready to receive the P-8A, which will provide the users and operators a step increase in mission capabilities,” said Rear Admiral Paul Grosklags, U.S. Navy Program Executive Officer for Air Anti-Submarine Warfare, Assault & Special Mission Programs. “Thanks to Boeing and the entire team for its efforts and great partnership to date.”
Following delivery in Seattle, Navy pilots flew the first production P-8A, LRIP1-1, to Naval Air Station Jacksonville, Fla., where it will be used for aircrew training.
The Poseidon team is using a first-in-industry in-line production process that draws on Boeing’s Next-Generation 737 production system. All P-8A-unique aircraft modifications are made in sequence during fabrication and assembly.
Along with production aircraft, the P-8A team also has built and is testing six flight-test and two ground-test aircraft. The flight-test aircraft are based at Naval Air Station Patuxent River, Md., and have completed more than 1,500 flight hours.
A derivative of the Next-Generation 737-800, the Poseidon is built by a Boeing-led industry team that includes CFM International, Northrop Grumman, Raytheon, Spirit AeroSystems, BAE Systems and GE Aviation.
The Navy plans to purchase 117 Boeing 737-based P-8A aircraft to replace its P-3 fleet. Initial operational capability is planned for 2013.

U.S. Guided-Missile Frigate Makes First Full Deployment with Own UAV Capability
USS SIMPSON, Gulf of Guinea | The guided-missile frigate USS Simpson (FFG 56) has the Unmanned Aerial Vehicle (UAV), MQ-8B Fire Scout embarked for solo missions, a U.S. Navy first during a full deployment, Mar. 7. The Fire Scout is the Navy’s only unmanned aircraft to operate on land and at sea. The Fire Scout is a vertical take-off and landing UAV capable of carrying out surveillance, tracking and targeting missions.
Lt. Cmdr. Darren Capo is the officer-in-charge of Helicopter Anti-Submarine Squadron Light Six Zero (HSL-60), the “Jaguars”, the detachment embarked on Simpson that maintains and flies the Fire Scout.
“There are benefits to flying from inside a ship,” said Lt. Cmdr. Capo, who’s previously flown the SH-60B Sea Hawk helicopter, about taking on his latest assignment.
Flying the Fire Scout has been a completely new experience, especially physically.
“When you’re done, your ears don’t ring from noise and vibration and you’re not soaked in sweat like you are after flying a long helicopter mission,” said Lt. Cmdr. Capo.
Two people operate the Fire Scout during flight, an Air Vehicle Operator (AVO) and a Mission Payload Operator (MPO). Both the AVO and MPO sit at control stations next to each other in the same room.
“Nothing can beat the sensation of flying a helicopter, but flying the Fire Scout is really cool knowing that you’re on the cutting edge of technology,” said Lt. Cmdr. Capo.
The AVO is responsible for the overall current mission, navigation and system safety of the Fire Scout’s airframe. The MPO is responsible for operating the Fire Scout’s built-in surveillance camera and communicating with the AVO to get the best shots needed during a mission.
“It’s much like a video game with a trackball, keyboard and two monitors to handle all the open windows,” Lt. Cmdr. Capo said about operating the Fire Scout as an AVO. “It’s very interesting if you’re willing to learn new ways of flying.”
Lt. Cmdr. Capo also said the future of air warfare will include a large contribution from UAV’s. “The Fire Scout is a truly remarkable piece of equipment that will make its mark on naval aviation for years to come,” said Lt. Cmdr. Capo. “The capabilities and freedom from risk of human life are significant benefits to employing the Fire Scout.”
HSL-60 embarked on Simpson with two Fire Scouts and a crew of 15 maintainers; three aircrew act as MPO’s and four pilots act as AVO’s.
“So far it’s been good working with the Fire Scout’s system,” said Aviation Machinist’s Mate 2nd Class Jonathan Moody, one of HSL-60’s maintainers working with the Fire Scout. “I’m glad to be involved with something that’s part of the Navy’s future and a growing portion of intelligence gathering.”
“I see the Fire Scout as a risk mitigator,” said Petty Officer Moody, who volunteered from his parent command in San Diego to embark with HSL-60 specifically to have a chance to work with the Fire Scout. “It gives you all that you can get from a manned aircraft, but with no exposure to danger for the air crew.”
Petty Officer Moody often finds himself working with a laptop right next to the Fire Scout before and after launch and recoveries. He said such interfacing makes his job of running aircraft diagnostics much easier.
“Having a computer to assist with aircraft diagnostics is more maintenance-friendly than without,” said Petty Officer Moody. “It allows you to find problems quickly and easily because all pertinent information is displayed on the monitor right in front of you, at a moment’s notice.”
Petty Officer Moody, like Lt. Cmdr. Capo, said he recognizes the larger role UAV’s will play in the Navy’s future, but he believes UAV’s won’t completely replace manned aircraft.
“UAV’s should be an addition to the Navy and work alongside manned aircraft,” said Moody, “but we still need manned aircraft for operations like Search and Rescue at sea.”
The Fire Scout was first deployed in 2009 aboard the guided-missile frigate, USS McInerney (FFG , in 2009. Since then it has exceeded 2,000 hours of real-time intelligence, surveillance and reconnaissance to support U.S. and allied troops in northern Afghanistan.
Simpson, homeported out of Mayport, Fla. is currently conducting theater security cooperation and maritime security operations in the Naval Forces Africa area of responsibility.

US Navy to formalise unmanned carrier strike plans
Washington DC - The US Navy is set to approve the unmanned carrier launched surveillance and strike (UCLASS) aircraft as a formal acquisition programme later this year, but has yet to decide the scope of what the type's limited operational capability - set for 2020 - will constitute.
"The contract award date will be [identified] in the approved strategy in support of a 2012 Milestone A decision," says navy UCLASS programme manager Charlie Nava in a written statement to Flightglobal. This status would signify that a new procurement programme has been formally approved.
The USN will issue a request for proposals (RfP) only after the service and the US Department of Defense have fully examined the data gathered from a previously issued request of information and broad agency announcement studies. The information collected is already proving to be useful, Nava says.
"The date is still [to] be determined," he says of a potential RfP. "The overarching acquisition strategy for UCLASS is being vetted through the Department of [the] Navy and Office of the Secretary of Defense."
On 24 February, the navy announced it would seek further broad agency studies, having awarded four such studies last June. According to the navy, these will help to develop new operating concepts, system architectures, requirements documents and examine new "potential material solutions" to meet its operational needs.
In previous years, the USN emphasised getting the unmanned reconnaissance and strike aircraft into service as soon as possible, with an initial operational capability date set for 2018. However, with the roll-out of President Barack Obama's fiscal year [FY] 2013 budget request, the service says "limited operational capability" will be pushed back to FY2020.
The delay was not unexpected, says analyst Dan Goure of the Lexington Institute in Virginia. "That wasn't surprising, really," he says. The navy still has not clearly articulated what the aircraft's role will be and the technology is still very immature, Goure adds.
The navy says it needs a carrier-based unmanned air system to provide persistent intelligence, surveillance and reconnaissance (ISR) and precision strike capabilities.
Much of the technology needed for the UCLASS is being developed and tested under the auspices of the navy's X-47B unmanned combat air system demonstration (UCAS-D) effort being performed by Northrop Grumman. The service hopes that the UCLASS will be an operational follow-on to the X-47B.
"The ongoing UCAS-D programme is an essential early step that will demonstrate the suitability of unmanned air systems operating in the [carrier] environment, but contains no operational mission systems," Nava says. "UCLASS will be the navy's first carrier-based operational unmanned air system capable of integrating with manned platforms as part of the Carrier Air Wing."
Technology from the X-47B, including government-owned hardware, software and aircraft-ship interfaces, will also be harvested for the UCLASS effort, Nava says.
According to the solicitation for additional broad agency announcement studies last month, an operational system would consist of an air segment, which includes the air vehicle, ISR hardware and remote vehicle control system. But the UCLASS would also include a control system and connectivity segment that would be able to link to other US military assets and a carrier segment for shipboard interfaces, shipboard facilities and aircraft launch/recovery apparatus.
While it might be possible to bring the aircraft into "limited" service by 2020, it is not clear what the navy means by limited operational capability, Goure says.
The navy does not disagree, having yet to fully flesh out what it hopes to accomplish.
"Based upon the ongoing analysis, the navy has recently identified 2020 as the operational assessment timeframe," Nava says. Right now, it is using the terms "operational assessment" and "limited operational capability" interchangeably, he adds.
The challenge will be to build an aircraft that can not only operate routinely from the deck of a carrier at sea, but also conduct some sort of useful mission once it is in the air, Goure says.
Given the state of the technology and current budgetary climate, entering into an operational assessment phase by 2020 might be a more reasonable objective, Goure says.
"An operational assessment is much more limited than an initial operating capability," he says. "That would make more sense."
Industry officials say the navy's plans are too nebulous for them to comment in any meaningful way.
The USN has asked for just over $122 million in the FY2013 budget proposal to fund the UCLASS programme.
If there are no further defence cuts, the navy might have a chance of funding the programme to fruition, Goure says. But if US defence outlays are seriously curtailed because of the so-called budget sequestration measure in Congress, he believes the UCLASS programme is all but doomed.

Boeing Delivers 1st Aircraft Under US Navy F/A-18E/F and EA-18G MYP III Contract
(Photo: Boeing)
Current Super Hornet and Growler Multi-Year Procurement contract provides more than $605M in savings
15:17 GMT, March 15, 2012 ST. LOUIS | Boeing has completed delivery of the U.S. Navy's first aircraft acquired through the F/A-18E/F and EA-18G Multi-Year Procurement (MYP) III contract, ahead of schedule.
Aircraft G-57, an EA-18G Growler, was the first of 148 F/A-18E/Fs and EA-18Gs that the Navy will purchase through the contract. The aircraft was delivered to the Navy on Jan. 26 and arrived at its home base at Naval Air Station Whidbey Island on Jan. 30.
On Sept. 28, 2010, the Navy awarded Boeing the MYP III contract for delivery of 66 F/A-18E/Fs and 58 EA-18Gs, to be purchased through 2013. The Navy has since expanded the contract with the addition of 24 F/A-18E/Fs. The Navy has the option to procure up to 194 F/A-18E/Fs and EA-18Gs under the MYP III contract terms.
"This program continues to successfully draw on efficiencies from across Boeing to reduce cost, while increasing capability for the men and women who serve this nation around the globe," said Mike Gibbons, Boeing F/A-18 and EA-18 Programs vice president. "Today's new Super Hornets provide unequaled air dominance and precision strike capability for the U.S. Navy carrier fleet. At the same time, the EA-18G continues to expand its dominance as the world's premier airborne electronic attack aircraft, as demonstrated by its recent successes supporting operations in Libya. The Super Hornet and Growler give the U.S. Navy a significant capability for a broad spectrum of anti-access, area-denial missions."
Boeing delivered 210 Super Hornets to the Navy during MYP I, which spanned fiscal years 2000 through 2004. The company then received a second multi-year contract that included 213 F/A-18E/F and EA-18G aircraft, and spanned fiscal years 2005 through 2009. Through fiscal year 2009, 44 more aircraft were added to MYP II, including 24 F/A-18Fs acquired by the Royal Australian Air Force under a Foreign Military Sales agreement with the U.S. Navy.
Procuring aircraft through the first two multi-year contracts generated $1.7 billion in savings for the Navy. The MYP III contract is projected to generate more than $605 million in savings, for total savings of more than $2.3 billion across the three F/A-18E/F and EA-18G contracts.
The Boeing F/A-18E/F Super Hornet is a low observable, multirole aircraft that performs virtually every mission in the tactical spectrum, including air superiority, day/night strike with precision-guided weapons, fighter escort, close air support, suppression of enemy air defenses, maritime strike, reconnaissance, forward air control and tanker missions. Boeing has delivered more than 480 F/A-18E/Fs to the U.S. Navy. The F/A-18E/F has logged more than 166,000 combat flight hours supporting operations in Iraq and Afghanistan.
The Boeing EA-18G Growler is the only air combat platform that delivers full-spectrum airborne electronic attack capability along with the targeting and self-defense capabilities derived from the F/A-18E/F Block II Super Hornet. A derivative of the two-seat F/A-18F Block II, the EA-18G's highly flexible design enables warfighters to operate either from the deck of an aircraft carrier or from land-based airfields. The EA-18G was a critical platform employed during NATO operations in Libya in support of Operation Odyssey Dawn in 2011. The EA-18G logged more than 7,000 combat flight hours supporting operations in Libya.

La marine américaine va doubler ses capacités anti-mines dans le golfe Persique
Actuellement, la Ve Flotte de l’US Navy, dont l’état-major est basé à Bahrein, dispose de 4 navires de type « chasseur de mines », lesquels sont prêts à intervenir au cas où Téhéran serait tenté de bloquer le détroit d’Ormuz, comme ses dirigeants ont récemment menacé de le faire quand il était question d’appliquer à leur pays des sanctions visant ses exportations pétrolières afin de le contraindre à coopérer avec l’Agence internationale de l’énergie atomique (AIEA) sur son programme nucléaire controversé.
Justement, l’ambition prêtée à la République islamique de se doter d’armes nucléaires et l’ambiguïté qu’elle cultive à ce sujet font que les rumeurs d’une opération militaire isréalienne contre les sites du programme iranien se font pressantes, même si une telle intervention paraît compliquée à planifier sur le papier.
Quoi qu’il en soit, si une telle opération doit avoir lieu, elle provoquerait des tensions dans le détroit d’Ormuz, d’une importance stratégique évidente quand l’on sait que près de 40% du trafic maritime pétrolier mondial y transite. Ainsi, la marine iranienne pourrait miner ce goulet (50 km de large pour 60 m de profondeur), ce qui interdirait le passage aux navires commerciaux.
Même si les Etats-Unis ne sont pas favorables à une action israélienne contre les complexes nucléaires iraniens, il n’en reste pas moins que le détroit d’Ormuz peut faire l’objet d’un blocus imposé par l’Iran en raison, par exemple, de tensions avec les monarchies pétrolières du Golfe persique, lesquelles sont par ailleurs en pointe contre le régime syrien de Bachar el-Assad, soutenu par Téhéran.
Aussi, « afin de répondre à une éventuelle action de l’Iran visant à bloquer le détroit d’Ormuz », le chef des opérations de l’US Navy, l’amiral Jonathan Greenert, a annoncé, le 15 mars, le déploiement de 4 chasseurs de mines supplémentaires dans le golfe Persique. Les bâtiments concernés sont les USS Sentry, Devastator, Pioneer et Warrior. En outre, des hélicoptères MH-53 Sea Dragon, dotés d’équipements de lutte anti-mines, seront également envoyés en renfort dans le secteur.
Par ailleurs, les corvettes israéliennes INS Lahav et INS Yaffo, armées de missiles anti-navire, ont franchi, le 13 mars dernier, le canal de Suez, officiellement pour rejoindre la base d’Eilat, sur la mer Rouge. Ce déploiement répond sans doute à celui de deux bâtiments de la marine iranienne, qui s’étaient rendus en Syrie le mois dernier, comme cela avait été le cas en août 2011.

L'US Navy désarme deux frégates du type O.H. Perry
L'USS Boone crédits : US NAVY
19/03/2012
La marine américaine continue de désarmer ses frégates du type O.H. Perry (FFG 7). Ainsi, les USS Boone (FFG 28) et USS John L. Hall (FFG 32), qui datent de 1982, ont été retirées du service, respectivement le 23 février et le 9 mars. L'US Navy ne compte donc plus que 25 frégates de ce type opérationnelles, sur les 51 qui avaient initialement été construites. Le prochain bâtiment à être désarmé sera l'USS Crommelin (FFG 37) le 30 octobre prochain. Puis, en 2013, ce sera au tour de l'USS Underwood (FFG 36) le 15 février, de l'USS Curts (FFG 38) le 27 février, de l'USS Carr (FFG 52) le 15 mars, de l'USS Klakring (FFG 42) le 22 mars et de l'USS Reuben James (FFG 57) le 30 août. Dans les prévisions de désarmement de l'US Navy, 7 autres frégates de ce type seront retirées du service en 2014 : Les USS Halyburton (FFG 40), USS Mc Clusky (FFG 41), USS Thach (FFG 43), USS De Werft (FFG 45), USS Rentz (FFG 46), USS Nicholas (FFG 47) et USS Robert G. Bradley (FFG 49). Longues de 138.8 mètres pour un déplacement de 4100 tonnes en charge, les frégates du type O.H. Perry disposent d'un canon de 76mm, un système multitubes Phalanx, deux canons de 25mm, des mitrailleuses de 12.7mm et deux hélicoptères. Elles sont remplacées par les nouveaux Littoral Combat Ship (LCS).
The future USS Michael Murphy (DDG 112), and the final ship of the original 62-ship procurement of the DDG 51 class shipbuilding program, successfully completed a combined builder's and acceptance "super trial" March 9, after spending four days underway in the Atlantic Ocean.
Because of the maturity of the class, the Navy holds only one round of trials on each ship prior to delivery, instead of separate builder's and acceptance trials. This "super trial" requires less time, fuel and manpower than the typical method.
During the trial, Bath Iron Works and the U.S. Navy's Board of Inspection and Survey (INSURV) tested the ship's weapons, communications, and propulsion systems as well as conducting several other inspections including habitability, water purification and food preparation.
"DDG 112's strong performance in these combined trial has a very special significance," said Capt. Mark Vandroff, DDG 51-class program manager for the Navy's Program Executive Office (PEO) Ships. "The success of these trials after 62 ships underscores the value of the DDG 51 class and its continued importance to the 21st century surface fleet."
The DDG 51 class ship is a multi-mission guided missile destroyer designed to operate in multi threat air, surface and subsurface threat environments. The class provides outstanding combat capability and survivability characteristics while minimizing procurement and lifetime support costs due to the program's maturity. The DDG 51 program continues to reinforce affordability and efficiency in its shipbuilding program, with a commitment to deliver ships at the highest possible quality allowing seamless transition to the fleet.
The new destroyer honors the late Lt. Michael P. Murphy, who was posthumously awarded the Medal of Honor for his actions as leader of a Navy SEAL team in Afghanistan. Lt. Murphy was the first person to be awarded the medal for actions in Afghanistan and the first member of the Navy to receive the award since the Vietnam War.
These trials are the last significant production milestone before delivery of the ship to the Navy this spring. A commissioning ceremony will be held in New York City in October.
As one of the Defense Department's largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft. Currently, the majority of shipbuilding programs managed by PEO Ships are benefiting from serial production efficiencies, which are critical to delivering ships on cost and schedule.

La marine américaine se séparera en 2013 de 10 grands bâtiments de combat
L'US Navy va connaître un trou d'air dans ses capacités l'an prochain avec le désarmement de 10 grands bâtiments. Tout d'abord le porte-avions à propulsion nucléaire USS Entreprise (CVN 65), qui doit être désarmé le 15 mars 2013. Le bâtiment, qui effectue actuellement le dernier déploiement de sa carrière, sera remplacé par le futur USS Gerald R. Ford (CVN 78), dont l'entrée en service n'est pas prévue avant 2015. Dans le même temps, la marine américaine va se séparer l'an prochain de quatre croiseurs lance-missiles du type Ticonderoga : L'USS Cowpens (CG 63), l'USS Anzio (CG 68), l'USS Vicksburg (CG 69) et l'USS Port Royal (CG 73), dont le retrait est fixé au 31 mai 2013. On notera que le Port Royal, mis en service en 1994, est le plus récent des croiseurs de ce type. Mais le bâtiment a été victime d'un grave échouement en février 2009 à Hawaii. Malgré un passage en cale sèche de 6 mois, les réparations menées sur le CG 73 ne seraient pas satisfaisantes, l'accident ayant apparemment fragilisé la structure. On notera que le remplacement de ces croiseurs n'est pas prévu, même si l'US Navy doit s'enrichir des trois gros destroyers lance-missiles du type Zumwalt (DDG 1000), dont le premier sera livré à partir de 2014. Dans le domaine des frégates, le nombre d'unités du type O.H. Perry (FFG 7) va encore se réduire l'an prochain. Après le désarmement cette année des USS Boone (FFG 28), USS John L. Hall (FFG 32) et USS Crommelin (FFG 37), cinq autres frégates sortiront en 2013 de l'ordre de bataille américain : les l'USS Underwood (FFG 36) le 15 février, l'USS Curts (FFG 38) le 27 février, l'USS Carr (FFG 52) le 15 mars, l'USS Klakring (FFG 42) le 22 mars et l'USS Reuben James (FFG 57) le 30 août 2013. Les bâtiments du type O.H. Perry doivent être remplacés par les nouveaux Littoral Combat Ship des types Freedom et Independence, dont 55 exemplaires sont prévus. Mais, pour l'heure, seules les deux premiers ont été livrés et deux autres sont en essais ou en achèvement à flot.

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.
